Description

Technical Field

[0001] The present invention relates to the technical field of eyelash beauty, and particularly to a seven-nourishing eyelash grafting method. Background Art

[0002] In recent years, the eyelash beauty industry has developed vigorously, and consumers' demand for eyelash grafting services has been increasing day by day. However, there are many limitations in traditional eyelash grafting methods, which are difficult to meet the growing personalized needs of customers and the high standards for eyelash beauty effects.

[0003] In the prior art, eyelash grafting usually relies on the experience and manual operation of eyelash beauticians, lacking accurate customer analysis and personalized design. This makes it difficult to ensure the consistency and durability of eyelash beauty effects, and at the same time, it cannot fully meet the personalized needs of different customers. In addition, traditional false eyelash materials and glue formulas often cannot balance comfort, safety, and durability, and are prone to causing eye discomfort or allergic reactions.

[0004] In terms of tool and environment preparation, the prior art mostly uses simple alcohol wiping or ultraviolet irradiation, which is difficult to achieve long-term antibacterial effects. This not only increases the risk of eye infections but also affects the long-term stability of eyelash beauty effects. At the same time, traditional eyelash beautician training methods are inefficient and difficult to quickly cultivate high-level professionals, restricting the development of the entire industry.

[0005] In view of the above problems, there is an urgent need for an innovative eyelash grafting method that can achieve accurate customer analysis, personalized design, a safe and comfortable grafting process, and long-term stable eyelash beauty effects. At the same time, an efficient quality control and training system is also needed to improve the service level of the entire industry. Summary of the Invention

[0006] Based on in-depth thinking about the above problems, the present invention proposes a new seven-nourishing eyelash grafting method.

[0018] (2) Only select the eyelashes in the robust growth stage (i.e., prime period) for grafting.

[0019] Specifically, the tool and environment preparation includes the following steps:

[0020] (1) First, soak all tools in 75% alcohol for 5 minutes;

[0021] (2) Second, disinfect the tools with ultraviolet light of wavelength 254 nm for 15 minutes;

[0022] (3) Then, immerse the tools and false eyelashes in a 0.1 - 0.5 wt% silver nanosol for 30 - 60 seconds;

[0023] (4) Again, dry at 60 - 80 °C for 10 - 15 minutes;

[0024] (5) Finally, conduct ultraviolet irradiation treatment with a wavelength of 254 nm for 5 - 10 minutes.

[0025] Specifically, the grafting process includes the following steps:

[0026] (1) Eye cleaning and protection:

[0027] a) Clean the periocular area with a mild eye cleaning solution with a pH value of 6.5 - 7.5;

[0028] b) Apply an eye patch to protect the lower eyelashes and fix the adhesive tape on the leading edge of the eye patch;

[0029] (2) Eyelash selection and preparation:

[0030] a) Based on the AI analysis results, select the eyelashes in the prime period for grafting;

[0031] b) Use a modified bionic false eyelash, and its material composition (parts by weight) is:

[0032] 70 - 80 parts of modified polyamide fiber;

[0033] 5 - 10 parts of silicone copolymer;

[0034] 2 - 5 parts of amino silicone oil;

[0054] (3) The specific grafting steps are as follows:

[0055] a) Separate the eyelashes: Hold the forceps vertically with the left hand and separate a single eyelash independently at 2 mm from the natural eyelashes;

[0056] b) Pick up the false eyelashes: Use the curved forceps in the right hand to pick up the false eyelashes, and pick up at the one - third part close to the tip of the false eyelashes;

[0057] c) Glue picking: Hold the root of the false eyelashes vertically downward and slowly place it in the middle of the dripping glue, so that two-thirds of the bottom of the false eyelashes are completely immersed in the glue, and then quickly lift it up to ensure that 3 drops of glue adhere to the false eyelashes. The drop at the bottom is larger in volume, and the two drops on the top gradually become smaller, with an equal distance between adjacent drops;

[0058] d) Glue sliding: Hold the tip of the natural eyelashes to be grafted upward, parallelly attach the false eyelashes with the picked glue to a single separated natural eyelash, and slide the false eyelashes up and down along the curvature of the natural eyelash. The sliding curvature is small and the frequency is fast. Slide 7 - 8 times. Each time during sliding, keep a distance of 1 mm between the root of the false eyelashes and the root of the natural eyelashes. After sliding, make the root of the false eyelashes stay at a position 1.5 mm away from the root of the natural eyelashes;

[0059] e) Eyelash fixing: Hold the eyelashes after glue sliding with straight forceps and keep the tip of the eyelashes upward for 3 seconds.

[0060] Specifically, the supplementary grafting includes the following steps:

[0066] b) If any problems are found, immediately remove and re - graft;

[0067] (2) Shaping and cleaning:

[0068] a) Use a small fan to dry the glue on the upper surface of the eyelashes for 3 - 5 minutes;

[0069] b) Carefully remove the adhesive tape and eye patch;

[0070] c) Clean the upper and lower eyelid positions with a cotton swab soaked in clear water;

[0071] (3) Post - care:

[0072] a) Provide a multi - functional care spray, and its ingredients (by weight) are:

[0073] Glycerol 5 - 10 parts;

[0074] 1 - 3 parts of glutathione;

[0075] 0.5 - 1 part of polyhexamethylene biguanide;

[0077] 0.5 - 1 part of phenoxyethanol;

[0078] 82 - 92.8 parts of purified water;

[0079] b) Guide the customer to use the care spray correctly, once in the morning and once in the evening every day, spraying at a distance of 20 cm from the eyes.

[0080] The innovation points and technical effects of the present invention are mainly reflected in the following aspects:

[0081] It is particularly worth mentioning that the intelligent responsive multifunctional nano - glue in the present invention exhibits excellent performance. Among them, the modified polyurethane resin, as the main material, optimizes its flexibility and bonding strength through molecular design. The introduction of chitosan derivatives and sodium hyaluronate not only enhances the biocompatibility of the glue but also endows it with moisturizing and nourishing functions. The synergistic effect among these components forms a dynamically balanced network structure at the molecular level, which can adaptively adjust its physicochemical properties according to environmental changes.

[0082] From the perspective of molecular orbital theory, the amino and carbonyl groups in the modified polyurethane resin form a complex hydrogen - bond network with the hydroxyl groups in chitosan derivatives and sodium hyaluronate. This network structure not only provides excellent bonding performance but also enables controlled release of moisture and nutrients at the microscale. At the same time, the introduction of the nano - silver - copper composite, through its special electronic structure, while maintaining antibacterial properties, can also form a synergistic effect with other components to enhance the overall stability.

[0083] At the process level, the present invention innovatively adopts the plasma - nano composite disinfection technology and the dynamic multi - point positioning method, significantly improving the accuracy and safety of the grafting process. High - energy low - temperature plasma can not only effectively kill microorganisms but also activate the material surface at the nanoscale, enhancing the effect of subsequent treatment. This multi - level synergistic effect, from the molecular level to the macroscopic effect, jointly constructs a highly integrated eyelash extension system.

[0084] The beneficial effects of the present invention are not only reflected in the expected aesthetic effects, comfort and durability, but also include some unexpected positive effects. For example, the improvement of periocular microcirculation observed after long-term use may be due to the subtle effects of nanomaterials and smart pH regulators in the skin microenvironment. In addition, the anti-blue light performance exhibited by the bionic nanocomposite false eyelash material provides users with additional eye protection. This discovery has opened up a new direction for the development of functional eyelash products.

[0085] In general, the present invention not only solves many problems faced by traditional eyelash enhancement methods through the organic combination and synergy of multiple innovative technologies, but also creates a new paradigm for the eyelash enhancement industry. It not only improves the quality and effect of eyelash enhancement services, but also provides valuable ideas and experience for technological innovation in related fields. This all-round and multi-level innovation marks that eyelash enhancement technology has entered a new stage of development, and is expected to promote the entire industry to develop in a more scientific, personalized and healthy direction.

[0111] 4) Slowly add N-methylpyrrolidone and stir evenly to obtain a modified polyurethane resin solution.

[0112] The acrylate copolymer selects a commercial product with a glass transition temperature (Tg) between -20 and -10 °C, such as Acrysol ASE-60 from Rohm and Haas Company or Joncryl 77 from BASF Company, which can improve the flexibility and bonding strength of the glue.

[0113] Preparation method of chitosan derivative (N,O-carboxymethyl chitosan): Chitosan (degree of deacetylation ≥ 90%): 100 parts by weight; Chloroacetic acid: 120 - 150 parts by weight; Sodium hydroxide: 80 - 100 parts by weight; Isopropanol: 500 parts by weight; Deionized water: 1000 parts by weight

[0120] 6) Dialyze for 48 - 72 hours and freeze-dry to obtain N,O-carboxymethyl chitosan powder.

[0121] These refined formulations and preparation methods are designed to improve the innovation and effectiveness of the Qiyang Eyelash Extension Method. Nano-titanium dioxide, keratin hydrolysate, and optimized preparation processes can achieve synergistic effects in material properties. For example, nano-titanium dioxide can interact with modified polyamide fibers to improve the durability and UV resistance of false eyelashes; while keratin hydrolysate can synergistically act with amino silicone oil to improve the compatibility and comfort between false eyelashes and real eyelashes.

[0122] In the glue formulation, N-acetylcysteine can form additional cross-linking points with modified polyurethane resin to enhance the persistence of the glue; at the same time, it also has an antioxidant effect to protect other active ingredients. The addition of kojic acid can adjust the pH value of the glue and synergistically play an antibacterial role with chitosan derivatives to extend the service life of the glue.

[0123] The hindered phenolic antioxidant plays a crucial role in modified polyamide fibers. The four 3,5-di-tert-butyl-4-hydroxyphenyl groups in its molecular structure can effectively capture free radicals and prevent the oxidative degradation of polymer chains. Irganox1010 terminates the free radical chain reaction by donating hydrogen atoms. Its phenolic hydroxyl group reacts with polymer free radicals to generate stable phenoxy free radicals, thus interrupting the oxidation process. With amino silicone oil (such as When used in combination with ASF 66), Irganox 1010 not only protects polyamide fibers but also prevents the oxidation of silicone oil, extending the service life of the entire material system. In addition, Irganox 1010 can slightly enhance the UV resistance of the material, possibly due to the scattering effect of its macromolecular structure on UV light. Siloxane copolymer (Silwet L-7602, Dow Chemical Company), this polydimethylsiloxane-polyethylene glycol copolymer plays a key role as an interfacial modifier in false eyelash materials. The siloxane part of Silwet L-7602 provides hydrophobicity, while the polyethylene glycol segment provides hydrophilicity. This amphiphilic structure enables it to significantly reduce the surface tension of the material, improving the flexibility and comfort of false eyelashes. When used in combination with amino silicone oil (such as GP-4), Silwet L-7602 can form a more uniform surface coating, further enhancing the gloss and touch of false eyelashes. And this copolymer also has a weak anti-fogging property, possibly because the hydrophilic layer formed on the material surface can prevent water droplets from condensing. Amino silicone oil ( ASF 66, Wacker Chemie AG), aminopropyl polydimethylsiloxane plays a key modification role in false eyelash materials.

[0124] The amino terminus of ASF 66 can form a chemical bond with polyamide fibers, while the long-chain siloxane backbone provides excellent flexibility and heat resistance. When used in combination with a siloxane copolymer (such as SF1288), ASF 66 can significantly improve the abrasion resistance and chemical resistance of the material while maintaining a good touch. After long-term use, this material is also observed to have a certain static electricity elimination ability, possibly due to the presence of amino groups changing the charge distribution on the material surface. Vitamin E derivative (Toco-Pheryl PGS, DSM), this water-soluble vitamin E not only plays an antioxidant role in the false eyelash material but also provides additional biological activity. The tocopherol part in Toco-Pheryl PGS captures free radicals, while the polyethylene glycol succinate part increases its dispersibility in the aqueous phase. When used in combination with antioxidant 1010, Toco-Pheryl PGS can form a protective film on the material surface, not only enhancing the antioxidant effect but also providing trace amounts of nutrients. After long-term use of false eyelashes containing this derivative, customer feedback indicates that the growth condition of the eyelashes has improved, possibly due to the role of vitamin E in promoting microcirculation. Chitosan derivative (Chitoscience, Heppe Medical Chitosan GmbH), N,O-carboxymethyl chitosan plays a multifunctional role in the glue formulation. Carboxymethylation modification enhances the water solubility and biocompatibility of chitosan. Its polysaccharide structure can form a network structure, enhancing the adhesiveness and moisture retention of the glue. When combined with sodium hyaluronate, a complex polysaccharide network is formed, not only improving the bonding strength of the glue but also having excellent moisture retention and slow-release functions. This composite system also exhibits a certain antibacterial activity, possibly due to the antibacterial properties of chitosan itself being further enhanced during the carboxymethylation process.

[0125] In summary, the synergistic effect of these uncommon compounds not only achieves the expected performance improvement but also brings a number of unexpected positive effects. For example, the enhancement of antioxidant performance, the emergence of static electricity elimination ability, weak anti-fogging characteristics, the improvement of eyelash growth condition, and the generation of antibacterial activity, etc. These findings provide additional value for the Qiyang Eyelash Grafting Method and also point out new directions for future product development and technological innovation.

[0126] Example 1

[0127] This example provides a Qiyang Eyelash Grafting Method, which includes the following steps:

[0128] (1) Customer analysis and customization

[0129] First, use 3D facial scanning technology with an accuracy of ±0.1 mm to capture the customer's facial and eye structures. Secondly, adopt an AI-assisted design system to generate the best eyelash design based on the scanned data, facial golden ratio, customer's occupation, lifestyle, and personal style preferences. This high-precision scanning technology combined with the AI system can achieve highly personalized eyelash design and significantly improve customer satisfaction.

[0130] (2) Eyelash growth cycle analysis

[0131] Use a deep learning-based image analysis system with a training dataset of over 10,000 images to identify the growth stage of each eyelash. The system only selects eyelashes in the robust growth stage (i.e., prime years) for grafting, thus ensuring the durability of the grafting effect.

[0132] (3) Tool and environment preparation

[0133] Double disinfect and nano-silver antibacterial treatment for all tools, and the specific steps include:

[0134] a) First, soak the tools in 75% alcohol for 5 minutes;

[0135] b) Secondly, perform ultraviolet disinfection with a wavelength of 254 nm for 15 minutes;

[0136] c) Then, immerse the tools and false eyelashes in a 0.1 wt% nano-silver solution for 60 seconds;

[0137] d) Again, dry at 60 °C for 15 minutes;

[0138] e) Finally, perform ultraviolet irradiation treatment with a wavelength of 254 nm for 10 minutes.

[0139] This series of treatments can effectively kill various microorganisms and significantly reduce the risk of eye infections.

[0140] (4) Grafting process

[0141] The grafting process includes the following steps:

[0142] a) Eye cleaning and protection: Clean the periorbital area with a mild eye cleaning solution with a pH value of 6.5, then apply an eye patch to protect the lower eyelashes, and stick the tape on the front edge of the eye patch for fixation.

[0143] b) Eyelash selection and preparation: Based on the AI analysis results, select eyelashes in the prime years for grafting. Use modified bionic false eyelashes, and its material composition (parts by weight) is: 80 parts of modified polyamide fiber, 10 parts of silicone copolymer, 5 parts of amino silicone oil, 3 parts of organic pigment, 1 part of vitamin E derivative, 0.5 part of nano-titanium dioxide, and 1 part of keratin hydrolyzate.

[0144] c) Improved glue - sliding technique: Use a new type of multifunctional glue, and its formula composition (parts by weight) is as follows: modified polyurethane resin 50 parts, acrylate copolymer 15 parts, chitosan derivative 5 parts, sodium hyaluronate 3 parts, biotin 1 part, N - acetylcysteine 0.5 part, kojic acid 0.3 part, ethanol 15 parts, deionized water 10.2 parts. Adopt the manual glue - sliding method and combine it with a glue shaker.

[0145] d) Seven - point positioning method: Select and graft 7 key eyelashes in the following order:

[0146] 1. The second mature - stage eyelash counted from the inner canthus outwards;

[0147] 2. The first mature - stage eyelash counted from the outer canthus inwards;

[0148] 3. The mid - point between the first and the second;

[0149] 4. The mid - point between the first and the third;

[0150] 5. The mid - point between the fourth and the second;

[0151] 6. The mid - point between the first and the fourth;

[0152] 7. The mid - point between the fifth and the second; By selecting the eyelashes at 7 key positions for grafting, the overall contour can be quickly formed, improving efficiency and uniformity.

[0153] The specific grafting steps are as follows:

[0154] Separate the eyelashes: Hold the forceps vertically with the left hand and separate a single eyelash independently 2 mm above the natural eyelashes;

[0155] Pick up the false eyelash: Use the curved forceps in the right hand to pick up the false eyelash, and pick up the one - third part near the tip of the false eyelash;

[0156] Pick up the glue: Hold the root of the false eyelash vertically downward and slowly place it in the middle of the dripping glue, so that two - thirds of the bottom of the false eyelash is completely immersed in the glue, and then quickly lift it up to ensure that 3 drops of glue adhere to the false eyelash, with a larger drop at the bottom and two gradually smaller drops on the top, and the distance between adjacent drops is equal;

[0157] Slide the glue: Keep the tip of the natural eyelash to be grafted upward, parallelly attach the false eyelash with the picked - up glue and the separated single natural eyelash, and slide the false eyelash up and down along the curvature of the natural eyelash. The sliding curvature is small and the frequency is fast. Slide it 7 - 8 times. Each time when sliding, keep a 1 - mm distance between the root of the false eyelash and the root of the natural eyelash. After sliding, make the root of the false eyelash stay at a position 1.5 mm away from the root of the natural eyelash;

[0158] Fixing the Eyelashes: Hold the eyelashes after applying the sliding glue with straight forceps, and keep the tips of the eyelashes upward for 3 seconds.

[0159] e) Supplementary Grafting: According to the number of natural eyelashes, evenly select the sparse positions of the eyelashes for supplementary grafting. Adopt a skipping grafting method. Each time when selecting the next eyelash for supplementary grafting, keep it far away from the previously grafted eyelash. This can avoid overcrowding in a local area and achieve a more natural effect.

[0160] (5) Post-treatment and Care

[0300] (5) Intelligent evaluation system: Using computer vision and 3D modeling technologies, it conducts a comprehensive evaluation of the completed eyelash extension works. The system can accurately measure the position, angle, and curvature of each eyelash and compare them with the design plan to give an objective quality score. At the same time, the system will also generate a detailed improvement suggestion report.

[0301] (6) Continuous learning module: The system continuously collects and analyzes the latest eyelash extension technology and trend data, and automatically updates the training content and evaluation criteria. Eyelash extension technicians can participate in online courses, technical discussions, and virtual workshops through this module to keep their skills continuously updated.

[0302] This comprehensive quality control and training system can not only ensure the high quality and consistency of the grafting process, but also greatly shorten the learning curve of eyelash extension technicians and improve the service level of the entire industry. Through continuous data collection and analysis, the system can also continuously optimize the grafting method and promote the progress of eyelash extension technology. At the same time, the modular design of this system allows for flexible configuration according to different requirements and budgets, making it suitable for eyelash extension institutions of various scales.

[0303] Preferably, in the embodiments of the present invention, this quality control and training system can be seamlessly integrated with the aforementioned Qiyang Eyelash Extension Method to form a complete intelligent eyelash extension ecosystem. This can not only ensure the high quality of each eyelash extension service, but also promote the entire industry to develop in a more professional, precise, and personalized direction.

[0304] Comparative Example 1: Traditional customer analysis and customization method

[0305] This comparative example provides a method for analyzing and customizing clients for the Seven Nourishing Eyelash Grafting method, using traditional manual measurement and empirical design methods. Specifically, the eyelash beautician uses an ordinary tape measure to measure the key facial dimensions of the client, with an accuracy of approximately ±1 mm. Subsequently, based on personal experience and a simple paper template, an eyelash design plan is drawn. This method is in sharp contrast to Example 1, lacking precise data support and personalized consideration.

[0306] In practical applications, this traditional method results in significantly lower accuracy and personalization of the design plan compared to Example 1. Through a satisfaction survey of 100 clients, it shows that the satisfaction rate of clients using the traditional method is only 65%, while the satisfaction rate of clients using the method of Example 1 is as high as 95%. This significant difference fully demonstrates the importance of the 3D scanning technology (accuracy ±0.1 mm) and the AI-assisted design system in the present invention, which can provide more precise facial data and more personalized design plans, thereby greatly improving client satisfaction.

[0307] Comparative Example 2: Method for Analyzing the Eyelash Growth Cycle by Simple Image Analysis

[0308] This comparative example provides another method for the Seven Nourishing Eyelash Grafting method. For the eyelash growth cycle analysis step, simple image processing technology is used. Specifically, an ordinary digital camera (with a resolution of 12 million pixels) is used to take photos of the client's eyelashes, and then analyzed through basic image processing software to identify the approximate length and density of the eyelashes. This method is in contrast to Example 2, lacking the support of deep learning algorithms and large-scale training datasets.

[0309] In a three-month follow-up survey, the durability of the grafting effect using the simple image analysis method is significantly lower than that of Example 2. Specifically, the average maintenance time of the grafting effect using the simple image analysis method is 3.5 weeks, while the average maintenance time of Example 2 reaches 6 weeks. This result fully demonstrates the importance of the deep learning-based image analysis system (training dataset > 10,000 images) in the present invention, which can more accurately identify eyelashes in the vigorous growth period, thereby significantly improving the durability of the grafting effect.

[0310] Comparative Example 3: Preparation of Tools and Environment by Conventional Disinfection Methods

[0311] This comparative example provides a third method for the Seven Nourishing Eyelash Grafting method. For the tool and environment preparation step, only conventional alcohol wiping and ultraviolet irradiation disinfection methods are used. Specifically, first, the tools are wiped with 75% concentration alcohol, and then irradiated in an ultraviolet disinfection box for 15 minutes. This method is in contrast to Example 3, lacking advanced technologies such as nano-silver antibacterial treatment.

[0312] Through microbial culture experiments, it was found that after 24 hours of use, the number of surface bacteria on tools treated with conventional disinfection methods was 5 times that of the tools in Example 3. In a one-month customer survey, the probability of mild eye discomfort symptoms in the customer group using conventional disinfection methods was 20% higher than that in Example 3. This result fully demonstrates the importance of the nano-silver antibacterial treatment (0.1 - 0.5 wt% nano-silver solution) in the present invention, which can provide a more persistent antibacterial effect and significantly reduce the risk of eye infections.

[0313] Comparative Example 4: Grafting process of single-material false eyelashes

[0314] This comparative example provides a fourth Qiyang Meijie false eyelash grafting method, using traditional single-material false eyelashes during the grafting process. Specifically, the false eyelash material is only composed of polyamide fibers, and its preparation method is as follows:

[0315] Under nitrogen protection, 100 parts by weight of ε-caprolactam was heated to 220 °C, with a pressure of 0.1 MPa, and stirred and reacted for 4 hours. Subsequently, the temperature was lowered to 180 °C, the pressure was reduced to 5 kPa, and the reaction was continued for 2 hours. Finally, the product was extruded into filaments, cooled and pelletized to obtain single-material polyamide fiber pellets.

[0316] This method is in sharp contrast to Example 4 and lacks the synergistic effect of multi-component composite materials. Through customer experience surveys, it was found that the comfort score of using single-material false eyelashes was 35% lower than that of Example 4, and the naturalness score was 28% lower. In a four-week wearing test, the probability of deformation and curling of single-material false eyelashes was 2.2 times that of Example 4. This result fully demonstrates the importance of the multi-component composite materials in the present invention, especially the synergistic effect of siloxane copolymer (5 - 10 parts), amino silicone oil (2 - 5 parts) and vitamin E derivative (0.5 - 1 part), which significantly improves the comfort, naturalness and durability of false eyelashes.

[0317] Comparative Example 5: Improved slip glue technology for conventional glue

[0318] This comparative example provides a fifth Qiyang Meijie false eyelash grafting method, using conventional glue in the improved slip glue technology. Specifically, the glue formulation only contains the following components (parts by weight): 20 parts of acrylate copolymer, 20 parts of ethanol, and 60 parts of deionized water. Its preparation method is simple, and only needs to mix and stir the components evenly at room temperature. This method is in contrast to the new multi-functional glue in Example 1 and lacks functional components such as modified polyurethane resin.

[0319] Through the bonding strength test, it was found that the initial bonding strength of the conventional glue was similar to that of Example 1. However, during the simulated 3-week wearing process, the bonding strength decreased by 45%, while that of Example 1 only decreased by 8%. In addition, the customer group using the conventional glue reported a 40% higher eyelash loss rate than Example 1. This result fully demonstrates the importance of the multifunctional glue formulation in the present invention, especially the synergistic effect of modified polyurethane resin (40-50 parts), chitosan derivative (2-5 parts), and sodium hyaluronate (1-3 parts), which not only provides a lasting bonding effect but also has the function of nourishing and protecting the eyelashes.

[0320] Comparative Example 6: Quality Control and Training System of Traditional Training Method

[0321] This comparative example provides the sixth method for grafting seven-nourishing eyelashes. The quality control and training system adopts the traditional face-to-face teaching and experience accumulation method. Specifically, novice eyelash technicians learn by observing the on-site operations of senior eyelash technicians and practice on real models. Quality control mainly relies on the naked-eye observation and subjective judgment of senior eyelash technicians. This method is in sharp contrast to the high-tech quality control and training system of Example 4.

[0322] Through the comparison of the training effects over a period of 6 months, it was found that the average time required for novice eyelash technicians trained by the traditional method to reach a proficient level was 4 months, while those trained using the system of Example 4 only needed 2.5 months. In the customer satisfaction survey, the scores of eyelash technicians trained by the traditional method were 15% lower than those of Example 4. This result fully demonstrates the importance of the high-tech quality control and training system in the present invention, especially the synergistic effect of the real-time monitoring system (frame rate ≥ 240fps) and the VR training system (resolution ≥ 4K per eye, refresh rate ≥ 90Hz), which significantly improves the training efficiency and the consistency of service quality.

[0323] Through the above 6 comparative examples, it can be clearly seen the innovation points and superiority of the present invention in aspects such as customer analysis, eyelash selection, material preparation, glue formulation, and training system. These innovations not only improve each link of the grafting process respectively, but more importantly, there are significant synergistic effects among them, jointly enhancing the overall effect of the method for grafting seven-nourishing eyelashes. This all-round systematic innovation makes the present invention have outstanding creativity and practical value in the eyelash industry.

[0324] To comprehensively evaluate the effectiveness and superiority of the method for grafting seven-nourishing eyelashes, a series of test experiments were designed, covering multiple aspects such as aesthetic effect, comfort, durability, safety, and training efficiency. These experiments not only reflect the core innovation points of the present invention but also reveal the synergistic effects among various components and technologies.

[0325] Experiment 1: Customer Satisfaction and Aesthetic Effect Evaluation

[0326] Experimental method: 300 volunteers were recruited and randomly divided into 5 groups, and they received eyelash beautification services of Examples 1-4 and the traditional method (Comparative Example 1) respectively. After the service was completed, the eyelash beautification effects were scored by a professional aesthetics jury and the volunteers themselves. The scoring criteria included naturalness, three-dimensionality, fineness and overall coordination. Experimental results:

[0327] Table 1: Customer satisfaction and aesthetics effect scores (full score: 100 points)

[0328] Group Naturalness Stereoscopic effect Precision Overall coordination Customer satisfaction Example 1 92 90 93 91 93 Example 2 94 93 95 94 95 Example 3 96 95 97 96 97 Example 4 98 97 98 98 99 Comparative example 1 75 72 70 73 71

[0329] Analysis: Examples 1-4 were all significantly superior to the traditional method, and Example 4 was the most prominent. This fully demonstrated the synergistic effect of the 3D scanning technology, AI-aided design system and improved bionic false eyelash materials in the present invention, jointly enhancing the naturalness and fineness of the eyelash beautification effect.

[0330] Experiment 2: Comfort and safety evaluation

[0331] Experimental method: 150 volunteers were randomly selected from the volunteers in Experiment 1 and continuously wore them for one month. The eye comfort was evaluated and the safety was checked every week. The comfort score adopted a 0-10 scale (0 points being the least comfortable and 10 points being the most comfortable). At the same time, the incidence of adverse reactions such as eye inflammation and allergies was monitored. Experimental results:

[0332] Table 2: Comfort scores and safety data

[0333] Group Average comfort score Incidence of adverse reactions Example 1 8.5 2％ Example 2 8.8 1.5％ Example 3 9.2 0.8％ Example 4 9.6 0.3％ Comparative example 3 6.2 8％ Comparative example 4 5.8 7％

[0334] Analysis: The comfort scores of Examples 1-4 were significantly higher than those of the comparative example, and the incidence of adverse reactions was significantly reduced. This reflected the importance of the nano-silver antibacterial treatment and multi-component composite materials in the present invention. In particular, the intelligent responsive multi-functional nano glue formula in Example 4 not only improved the comfort but also significantly reduced the incidence of adverse reactions.

[0335] Experiment 3: Durability and stability test

[0336] Experimental method: The volunteers in Experiment 2 were followed up for 8 weeks, and the eyelash shedding rate and shape retention degree were recorded every week. The shape retention degree score adopted a 0-10 scale (0 points being completely deformed and 10 points being completely unchanged). Experimental results:

[0337] Table 3: 8-week durability and stability data

[0338] Group 4-week dropout rate 8-week dropout rate 4-week shape retention 8-week shape retention Example 1 15％ 35％ 8.5 7.2 Example 2 12％ 28％ 8.8 7.6 Example 3 8％ 20％ 9.2 8.3 Example 4 5％ 15％ 9.5 8.8 Comparative example 5 35％ 70％ 6 4.5

[0339] Analysis: The persistence and stability of Examples 1-4 are significantly better than those of Comparative Example 5. Especially in Example 4, a relatively low shedding rate and high morphological retention were maintained after 8 weeks. This fully demonstrates the synergistic effect of the improved bionic false eyelash material and the new multifunctional glue in the present invention, providing strong support for long-term eyelash beautification effects.

[0340] Experiment 4: Evaluation of Training Efficiency and Skill Improvement

[0341] Experimental method: 50 novice eyelash beauticians were recruited and randomly divided into 5 groups, and were trained respectively with the quality control and training system of Example 4 and the traditional training method (Comparative Example 6). The training period was 3 months, and skill evaluations were conducted once a month. The evaluation contents included operation speed, accuracy, and customer satisfaction. Experimental results:

[0342] Table 4: Data on Skill Improvement of Novice Eyelash Beauticians

[0343] Training method After 1 month After 2 months After 3 months Example 4 65 85 95 Comparative example 6 40 60 75

[0344] Note: The data are comprehensive scores (full score 100 points), including the weighted average of operation speed, accuracy, and customer satisfaction.

[0345] Analysis: By adopting the quality control and training system of Example 4, the skill improvement speed of novice eyelash beauticians is significantly faster than that of the traditional method. This highlights the superiority of the high-tech training system in the present invention, especially the synergistic effect of the VR training system and the real-time monitoring system, which greatly shortens the learning curve and improves the training efficiency.

[0346] Through the above series of experiments, not only the effectiveness and superiority of the Qiyang Eyelash Grafting Method were verified, but also some unexpected technical effects were discovered:

[0347] 1. Long-term care effect: The intelligent response type multifunctional nano glue in Example 4 not only provides excellent bonding performance, but also shows the effect of nourishing eyelashes during long-term use. The follow-up survey after 8 weeks found that the strength and gloss of the natural eyelashes of the customer group using this method have been significantly improved. This may be due to the continuous release of biotin-panthenol complex and cross-linked sodium hyaluronate in the glue in a trace amount, providing long-term nutritional support for the eyelashes.

[0348] 2. Microcirculation improvement: It was unexpectedly found that the microcirculation condition around the eyes of the customer groups of Example 3 and Example 4 was significantly improved after one month of use. This may be due to the synergistic effect of the nano-level material and the intelligent pH regulator, which unconsciously promotes blood circulation around the eyes, thus bringing unexpected skin care effects.

[0349] 3. Anti - blue light performance: During the durability test, it was unexpectedly found that the bionic nano - composite false eyelashes in Example 4 have certain anti - blue light performance. Further research shows that this may be due to the synergistic effect of functionalized graphene and nano - titanium dioxide, forming a microscopic protective barrier that provides additional protection for the eyes.

[0350] 4. Adaptive adjustment: The intelligent - response multi - functional nano - glue in Example 4 shows unexpected environmental adaptability. Under different temperature and humidity conditions, the glue can automatically adjust its physicochemical properties to maintain the best bonding state. This adaptive ability greatly improves the stability of the eyelash extension effect under various climate conditions.

[0351] 5. The role of the training system in promoting mental health: When evaluating the effectiveness of the training system, it was unexpectedly found that the group of eyelash extension artists using the training system in Example 4 showed higher job satisfaction and lower work pressure. In - depth analysis found that this may be due to the combination of the VR training system and the data - analysis platform, which not only provides skills training but also invisibly cultivates the self - confidence and sense of achievement of eyelash extension artists.

[0352] Through the synergistic effect of multiple innovative technologies, the Qiyang Eyelash Extension Method has achieved remarkable breakthroughs in aesthetic effects, comfort, safety, durability, and training efficiency. In particular, the technologies in Example 4, such as nano - level 3D scanning, AI - assisted design, breakthrough bionic nano - composite false eyelash materials, intelligent - response multi - functional nano - glue, etc., their synergistic effect not only brings the expected performance improvement but also produces a number of unexpected positive effects. These findings provide new ideas for the future development of the eyelash extension industry and also point the way for technological innovation in related fields.
