Description

Technical Field

[0001] The present invention relates to the field of medical cosmetic technology, and more specifically, to a facial contour enhancement method. This method is particularly suitable for improving problems such as sagging and unclear facial contours caused by facial aging. Through specific injection techniques and aesthetic designs, it achieves facial rejuvenation, naturalization, refinement, and sophistication. Background Art

[0002] In today's society, people's pursuit of beauty is ever-increasing, and facial aesthetics plays a crucial role in personal image. As we age, the face inevitably shows signs of aging, with facial sagging being one of the most prominent. Facial sagging is primarily caused by the laxity of soft tissue ligaments, which prevents facial tissue from maintaining its original position, resulting in blurred contours and a loss of firmness.

[0003] Traditional facial aesthetics systems often adhere to a standardized "three-part, five-eye" design. While this design has a certain aesthetic basis, it ignores the diversity of individual facial features. In practice, this one-size-fits-all design fails to meet the personalized aesthetic needs of different people and fails to fully showcase each person's unique charm.

[0004] Existing facial contour enhancement technologies have many limitations. For example, while some surgical methods can improve facial sagging to a certain extent, they are associated with significant trauma, long recovery times, and high risks, placing a significant physical and mental burden on those seeking the treatment. Common injection techniques, such as some simple hyaluronic acid fillers, lack precise point design and reasonable volume control, resulting in not only limited long-lasting effects but also the potential for adverse reactions such as unnatural facial appearance and swelling. Furthermore, some injection techniques fail to fully consider the facial bone characteristics and modern aesthetic trends of Asians, and are unable to effectively address common facial issues in Asians, such as high and wide cheekbones, making it difficult to achieve the desired facial contour enhancement and rejuvenation effects.

[0005] In this context, developing a facial contour enhancement method that is safe, effective, personalized and in line with modern aesthetics is of great practical significance. Summary of the Invention

[0006] The purpose of the present invention is to provide a facial contour lifting method, which aims to solve the problems of tissue sagging and unclear contours caused by facial aging, while meeting the personalized beauty needs of different groups of people and achieving the effects of facial rejuvenation, naturalization, refinement and sophistication.

[0007] To this end, the specific technical solutions adopted in the present invention are as follows:

[0008] Point design and quantity ratio control: This invention is based on in-depth research and analysis of a large number of clinical injection cases (tens of thousands of injection cases), and on the basis of the Juvederm MD-Codes injection technique and the Elivi C-type injection technique, it summarizes and determines 9 key injection points. Each point has been precisely quantitatively designed, and the quantity ratio is accurate to 0.01ml. The selection of these points is not determined arbitrarily, but takes into account the distribution of facial muscles, the structure of bones, and the characteristics of soft tissue. The movement and contraction of facial muscles will affect the shape and expression of the face, and the muscles in different parts have different requirements for hyaluronic acid filling and support; the bone structure provides a basic framework for the face, and understanding the shape and position of the bones will help to accurately inject to achieve a better lifting effect; the thickness and elasticity of the soft tissue determine the depth and quantity ratio of the injection. By comprehensively considering these factors, key parts can be accurately filled and lifted, laying a solid foundation for improving facial contours.

[0009] This invention also fully accounts for individual differences, flexibly adding "mobile rivet points" based on the patient's facial features (such as facial contour, facial proportions, and degree of soft tissue laxity) and aesthetic preferences (such as desired facial effects and personal style preferences), especially those with sagging. This personalized point design ensures effective improvement of common facial issues while precisely adjusting to each patient's unique situation, truly achieving personalized facial contour enhancement for each individual.

[0010] "Rivet" lifting principle: The fundamental reason for facial sagging is the relaxation of soft tissue ligaments, which can no longer support facial tissues, resulting in sagging and displacement of facial tissues. The present invention innovatively proposes the "rivet" lifting principle. Through a specific injection technique, hyaluronic acid is injected into the facial periosteum or ligaments at a fixed point and in a fixed quantity. This process is like implanting a "rivet" in the face, "nailing" the sagging facial tissue back into place, playing a role of stabilization and lifting. Hyaluronic acid has good viscosity and elasticity. After being injected into the periosteum or ligaments, it can be tightly combined with the surrounding tissues to form a stable support structure, effectively improving facial sagging and restoring a firm and smooth facial contour.

[0011] Injection material selection: In order to ensure the durability, stability and naturalness of the facial contour lifting effect, the present invention selects high-quality hyaluronic acid with low water absorption swelling rate, strong viscosity, strong elasticity and strong support as the main injection material. The low water absorption swelling rate prevents the face from becoming excessively swollen or unnatural due to water absorption by the material after injection, thus ensuring the natural beauty of the facial appearance; the strong viscosity and elasticity enable hyaluronic acid to better integrate with the surrounding tissues, deform naturally with changes in facial expressions, and avoid stiffness, while enhancing the filling and lifting effects; the strong support provides reliable support for the facial tissue, can effectively counteract the sagging force of the facial tissue, maintain the lifting effect of the facial contour, and maintain it for a longer period of time, reducing the trouble and cost of frequent treatments for those seeking beauty.

[0012] Aesthetic Design Guidance: This design utilizes Yang Qingqing's "Heart-Inside" aesthetic system for facial contouring. This aesthetic system integrates the characteristics of Asian facial bones with modern aesthetic trends. Using a "double-embedded heart" aesthetic, the facial contour is divided into two parts: the outer contour (large heart) and the inner contour (small heart), for reshaping and optimization.

[0013] The external contouring focuses on creating smooth, soft lines. By filling the temporal area and reducing the concavity, the facial lines become more rounded. The zygomatic lines are softened to avoid the harsh appearance caused by high and wide cheekbones. The mandibular margin is lifted and the skin and tissue in the jaw area are tightened to improve jawline sagging and excess fat, creating a clear, refined jawline and showcasing the elegance and refinement of the face.

[0014] The inner contour focuses on lifting the infraorbital soft tissue, increasing the fullness of the infraorbital area, improving tear troughs and dark circles, and making the eyes brighter and more energetic; strengthening the three-dimensional sense of the middle face, by filling and lifting the middle face, highlighting the apple muscles, making the face fuller and more three-dimensional; making the apple muscles more plump, and enhancing the youthful vitality of the face; fading nasolabial folds, reducing signs of facial aging, and achieving dual optimization of bone and skin structure, making the overall face more coordinated and natural, achieving a high-level aesthetic.

[0015] Application of makeup techniques: This invention cleverly draws on the techniques of using highlights to create visual emphasis and shadows to create visual weakening during makeup, and applies them to the field of medical beauty. By reshaping the highlight and shadow areas on the facial tissue with hyaluronic acid, the advantages of the face can be highlighted and the shortcomings of the face can be compensated according to the facial features of different beauty seekers. For example, injecting an appropriate amount of hyaluronic acid into the forehead, nose bridge, apple muscles and other parts to simulate the highlight effect during makeup, making these parts more prominent and enhancing the three-dimensional sense of the face; performing appropriate filling and adjustments on the higher cheekbones and mandibular angles to simulate the shadow effect and weaken the visual presence of these parts, thereby making the facial contour more natural and beautiful, and further enhancing the refinement and three-dimensional sense of the face.

[0016] Beneficial effects of the present invention

[0017] Personalized customization: Breaking through the limitations of traditional standardized design, based on different facial features and aesthetic demands, through 9 basic points and flexibly added mobile rivet points, we can achieve truly personalized facial contour enhancement for thousands of people and meet diverse aesthetic needs.

[0018] Safe and minimally invasive: Compared with traditional surgical methods, the injection method has the advantages of being minimally invasive and having no recovery period, which greatly reduces the surgical risks and the physical and mental burden of the patients, and is more easily accepted.

[0019] Significant results: Comprehensively improve facial features from multiple perspectives, effectively addressing facial sagging, achieving a lifted, firmer, smoother, and more refined contour, while achieving a youthful, natural, refined, and sophisticated look. Not only can it improve facial appearance, but it can also create a unique face that suits your personality, based on different aesthetic styles (such as Childlike Double Heart, Classic Double Heart, and Supermodel Peach Heart).

[0020] Long-lasting and stable: High-quality hyaluronic acid materials combined with precise injection techniques make the filling and lifting effects long-lasting and stable, reducing the trouble and cost of frequent treatments.

[0021] Aesthetic fusion: Combining makeup techniques with medical beauty technology, and guided by advanced aesthetic systems, it makes the shaping of facial contours more scientific and artistic, and enhances the overall beauty of the face. DETAILED DESCRIPTION

[0022] According to an embodiment of the present invention, a facial contour enhancement method is provided.

[0023] The following steps are involved:

[0024] Based on the Juvederm MD-Codes injection technique and the Elivi C-type injection technique, and taking into account the characteristics of facial muscles, bone structure, and soft tissue distribution, 9 key injection points were determined, with the dosage ratio at each point accurate to 0.01ml;

[0025] Add movable rivet points according to different facial features, aesthetic demands and facial sagging of different patients;

[0026] Use high-quality hyaluronic acid as the injection material, which has low water absorption and swelling rate, strong viscosity, strong elasticity and strong supporting force;

[0027] Through a specific multi-layer and multi-tunnel technique, hyaluronic acid is injected into the facial periosteum or ligaments at a fixed point to achieve facial tissue lifting.

[0028] Guided by Yang Qingqing's "Heart-Inside" love face aesthetic system, the system creates both inner and outer contour effects. The outer contour weakens the temple area depression, softens the zygomatic line, and lifts the mandibular margin. The inner contour lifts the infraorbital soft tissue, strengthens the mid-face three-dimensionality, makes the apple muscles more plump, and reduces the nasolabial folds.

[0029] Borrowing makeup techniques, hyaluronic acid is used to reshape highlight and shadow areas on facial tissue.

[0030] The 9 key injection points specifically include the center of the eyebrows, the eyebrow arch, the infraorbital point, the apple muscle point, the zygomatic arch point, the nose base point, the corner of the mouth point, the mandibular margin point, and the chin point. The amount ratio of each point is set according to the needs and aesthetic standards of different facial areas. The amount ratio range of the center of the eyebrows is 0.1-0.3ml, the amount ratio of the eyebrow arch point is 0.2-0.5ml, the amount ratio of the infraorbital point is 0.1-0.4ml, the amount ratio of the apple muscle point is 0.3-0.8ml, the amount ratio of the zygomatic arch point is 0.2-0.6ml, the amount ratio of the nose base point is 0.2-0.5ml, the amount ratio of the corner of the mouth point is 0.1-0.3ml, the amount ratio of the mandibular margin point is 0.3-0.7ml, and the amount ratio of the chin point is 0.3-0.6ml.

[0031] When adding mobile rivet points, for cases of cheek sagging, the new points are located in the soft tissue ligament in front or behind the masseter muscle of the cheek, and the injection volume is 0.1-0.3ml; for cases of neck laxity, the new points are located near the platysma muscle from below the mandibular angle to above the clavicle, and the injection volume is 0.2-0.5ml.

[0032] High-quality hyaluronic acid is a cross-linked sodium hyaluronate gel with a cross-linking degree between 5% and 10%, an average molecular weight of 1 to 3 million Daltons, a water absorption swelling rate of less than 10%, a viscosity coefficient greater than 2000cp, and an elastic modulus greater than 100kPa.

[0033] In the specific multi-level and multi-tunnel techniques, multi-level injection is divided into three layers: shallow, middle and deep. The shallow injection is located under the dermis, the middle injection is located in the fat layer, and the deep injection is located on the periosteum or ligament surface. When injecting multiple tunnels, the number of injection tunnels at the same point is 3-5, and the angle between the tunnels is 30°-60°.

[0034] When creating the inner and outer contours using Yang Qingqing's "Heart-Inside" love face aesthetic system, the standard for weakening the outer contour's temporal depression is to achieve a natural transition between the temporal area and the forehead and zygomatic lines. Softening the zygomatic lines means reducing the protrusion of the zygomatic arches so that the angle between the zygomatic arches and the cheeks on the side of the face is between 120°-135°. The standard for lifting the mandibular margin is that the mandibular margin lines are clear and smooth, and the angle with the neck is between 105°-120°. After the inner contour lifts the infraorbital soft tissue, a smooth transition is formed between the infraorbital area and the apple muscles. When the three-dimensional sense of the mid-face is enhanced, the mid-face height is increased by 2-3mm. The improvement in the fullness of the apple muscles is manifested as the highest point of the apple muscles moving up 2-3mm and the fullness increasing by 20%-30%. The degree of fading of the nasolabial folds is at least reduced by 2 levels.

[0035] When reshaping the highlight and shadow areas by drawing on makeup techniques, hyaluronic acid is injected into the forehead, nose bridge, apple muscles, chin and other parts to form highlight areas and increase the three-dimensional effect of the face. The injection volume of the forehead highlight area is 0.2-0.4ml, the injection volume of the nose bridge highlight area is 0.1-0.3ml, the injection volume of the apple muscle highlight area is 0.2-0.5ml, and the injection volume of the chin highlight area is 0.2-0.4ml; in the temporal area, below the cheekbones, mandibular angles and other parts, hyaluronic acid injection is reduced or a small amount of filling is performed to form shadow areas to modify the facial contour. The injection volume of the temporal shadow area is 0-0.1ml, the injection volume of the shadow area below the cheekbones is 0-0.2ml, and the injection volume of the mandibular angle shadow area is 0-0.1ml.

[0036] A comprehensive preoperative facial assessment also includes using 3D facial scanning technology to obtain accurate 3D facial data, as well as understanding the aesthetic psychological state of the patient through a psychological assessment questionnaire.

[0037] In the evaluation and adjustment of postoperative effects, professional facial contour measurement software is used for quantitative evaluation in short-term evaluation, and the dynamic changes in the patient's facial expressions are combined to evaluate the effects in long-term evaluation.

[0038] 1) Preoperative preparation

[0039] Facial Assessment: Professional 3D facial scanning equipment is used to obtain precise 3D facial data, covering the subtle contours, the precise morphology of the skeletal structure, and the thickness distribution of soft tissue. High-precision photography equipment is used to capture facial images from multiple angles for subsequent comparative analysis. A psychological assessment questionnaire is also used to gain a deeper understanding of the patient's aesthetic state, including their perception of their face, desired facial effects, and personal style preferences. Based on these assessment results, the most suitable aesthetic style is determined for the patient, such as Childlike Double Heart, Classic Double Heart, or Supermodel Peach Heart.

[0040] Material Preparation: Based on the results of the preoperative facial assessment, accurately calculate the required amount of high-quality hyaluronic acid. Select cross-linked sodium hyaluronate gel as the injection material, ensuring a cross-linking degree between 5% and 10%, an average molecular weight between 1 and 3 million Daltons, a water absorption swelling rate below 10%, a viscosity coefficient greater than 2000 cp, and an elastic modulus greater than 100 kPa. Also, prepare disposable sterile syringes, injection needles of varying sizes (to accommodate different injection sites and levels), disinfectants (such as iodine tincture, alcohol cotton balls, etc.), and first aid medications (in case of emergencies such as allergies).

[0041] Environmental Preparation: Surgery must be performed in a sterile operating room that meets medical standards. Preoperatively, the operating room is disinfected for at least 30 minutes using ultraviolet light. The operating table, instrument table, and other equipment surfaces are thoroughly cleaned and disinfected to ensure a sterile environment. The operating room temperature is maintained at 22-25°C and the humidity is maintained at 40%-60% to provide comfortable surgical conditions.

[0042] (2) Injection operation

[0043] Basic point injection: Injections are performed using a precisely graduated microsyringe at nine key injection points: the brow center, brow arch, infraorbital region, apple cheek, zygomatic arch, nasal base, corner of mouth, mandibular margin, and chin. During the injection process, the injection volume is strictly adhered to the prescribed range for each point. For example, the brow center injection volume range is 0.1-0.3 ml. The specific injection volume is determined based on the patient's forehead height, brow volume, and overall facial balance. During the injection, the injection depth and angle are precisely controlled to ensure that the hyaluronic acid is accurately injected into the facial periosteum or ligaments. For example, when injecting into the brow arch, to create a more profound effect, the injection angle should be adjusted based on the natural curvature of the brow arch and the patient's eye contour. Generally, the needle is inserted at a 30-45° angle to the skin, and the injection depth is controlled above the periosteum.

[0044] Mobile rivet point addition: Carefully observe the specific facial sagging of the patient. For sagging cheeks, additional points are added to the soft tissue ligaments in front of or behind the masseter muscle in the cheek. Before injection, gently press with your fingers to determine the optimal injection location, and the injection volume should be controlled between 0.1-0.3ml. For neck laxity, additional points are added near the platysma muscle below the mandibular angle and above the clavicle, with an injection volume of 0.2-0.5ml. When injecting, be careful to avoid the blood vessels and nerves in the neck. Use small doses and multiple injections to ensure a uniform and natural lifting effect.

[0045] Injection technique: Use a multi-level, multi-tunnel injection method. Multi-level injection is divided into three layers: shallow, middle, and deep. The shallow injection is located below the dermis and is mainly used to improve skin texture and minor depressions; the middle injection is located in the fat layer to enhance the filling effect; the deep injection is located on the periosteum or ligament surface, playing a key supporting and lifting role. When multi-tunnel injection is used, the number of injection tunnels at the same point is 3-5, and the angle between the tunnels is 30°-60°. For example, when injecting into the apple muscle point, a deep injection is performed first to inject most of the hyaluronic acid into the periosteum surface to provide stable support; then, the middle and shallow injections are performed to adjust the fullness and surface smoothness of the apple muscle. During the injection process, closely observe the patient's facial expressions and reactions, and adjust the injection dose and speed in a timely manner according to the actual situation to ensure a safe and comfortable injection process.

[0046] (3) Postoperative care

[0047] Wound Care: Immediately after the injection, gently press the injection site with a sterile cotton ball for 3-5 minutes until the bleeding stops. Instruct the patient to avoid contact with water for 24 hours after the procedure and to keep the injection site clean and dry. If slight bleeding occurs, gently wipe with iodine. Avoid touching the injection site for 3 days after the procedure to prevent infection.

[0048] Swelling Management: Slight swelling may occur after surgery, which is normal. Generally, the swelling will gradually subside within 1-3 days. It is recommended that patients apply cold compresses within the first 24 hours after surgery, using ice packs or cold towels (wrapped in clean plastic wrap to prevent moisture from contacting the wound), for 15-20 minutes each time, with intervals of 1-2 hours, to reduce swelling and pain. After 24 hours, apply hot compresses using warm towels (controlled at 40-50°C) for 15-20 minutes each time, 3-4 times a day, to promote blood circulation and accelerate the subsidence of swelling.

[0049] Daily precautions: Advise patients to avoid strenuous exercise, such as running, swimming, and fitness, within one week after surgery to prevent excessive facial muscle activity from affecting the injection effect. Avoid facial massage, especially the injection site, to prevent hyaluronic acid displacement. Avoid high-temperature activities such as saunas and hot springs within one week after surgery to prevent facial blood vessels from dilating and causing increased swelling. In terms of diet, avoid spicy and irritating foods, such as chili peppers, peppercorns, ginger, etc., as well as seafood and other foods that are prone to allergies. Eat more fresh fruits and vegetables, maintain good living habits and get enough sleep to help recover and maintain the injection effect.

[0050] (IV) Effect evaluation and adjustment

[0051] Short-term evaluation: 1-2 weeks after surgery, the patient will undergo the first effect evaluation. Professional facial contour measurement software will be used to quantitatively evaluate the patient's facial contour, including indicators such as the smoothness of the outer contour, the three-dimensionality of the inner contour, and the lifting effect of facial sagging. At the same time, the improvement will be visually demonstrated by comparison with preoperative facial photos and data. The patient will be asked about their satisfaction with the effect and whether they have any discomfort. If the local effect is found to be unsatisfactory, such as uneven filling or the lifting effect does not meet expectations, appropriate adjustments and supplementary injections can be made according to the specific situation. When making adjustments, the local area needs to be evaluated again to determine the dosage and location that need to be supplemented or adjusted to ensure that the adjusted effect is natural and beautiful.

[0052] Long-term evaluation: Long-term effect evaluation will be conducted 3-6 months after surgery. At this point, the hyaluronic acid has fully integrated with the facial tissue, and the effect is stable. Facial contour measurement software will be used again to evaluate the durability and naturalness of the facial contour, and to check for complications or adverse reactions such as local nodules, infection, and allergies. The dynamic changes in the patient's facial expressions will be observed to assess the naturalness and coordination of the hyaluronic acid in facial expressions. Based on the long-term evaluation results, the patient will be provided with follow-up maintenance recommendations, such as regular skin care and sun protection, as well as possible re-treatment plans. For example, based on the absorption of hyaluronic acid, the need for re-injection, as well as the timing and dosage of injections, will be determined.

[0053] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
