Description

Technical Field

[0001] This invention relates to the field of beauty technology, and more specifically to a method for promoting the absorption of beauty serums. Background Technology

[0002] Beauty serums are typically positioned as cosmetics with specific effects, highlighting at least one function, such as whitening, anti-oxidation, anti-aging, or soothing. They compensate for the shortcomings of traditional skincare products in terms of efficacy and are absorbed through the skin. To improve the skin's absorption efficiency, microneedles or bone needles (sponge bone needles) are used to puncture the skin to enhance the absorption of the beauty serum. Current technology often involves manually applying the beauty serum, which contains bone needles, and manually massaging to puncture the skin to promote absorption.

[0003] Microneedling has been proven to be an effective drug delivery method. Cosmed Pharmaceutical Co., Ltd. of Japan has successfully launched a microneedling product using sodium hyaluronate and collagen for whitening and spot removal applications. For example, patent document CN116687784 A discloses a cosmetic soluble microneedle, its preparation method, and its application. The microneedle comprises a first component, a second component, and water. The first component is an organic acid, and the second component is an amino acid and / or an active peptide. The mass ratio of the first component to the second component is 0.2-2:1. The mass percentage of injectable water is 0.05-5%, and the elastic modulus of the microneedle is greater than 1 GPa.

[0004] For example, document CN 105999535 A discloses the application of sponge spicules as a skin physical penetration enhancer. This application involves sponge spicules. The skin physical penetration enhancer includes skin drug physical penetration enhancers and skin care cosmetic physical penetration enhancers. The sponge spicules can be directly applied to cleansed skin. A sponge spicule solution is obtained by adding phosphate buffer to the sponge spicules to achieve a mass concentration of 10-100 mg / mL. The sponge spicule skin physical penetration enhancer composition includes sponge spicule drug formulation compositions and sponge spicule cosmetic formulation compositions. This sponge spicule skin physical penetration enhancer composition can be directly applied to cleansed skin. It overcomes the skin's stratum corneum barrier, promoting the transdermal absorption of drugs, vaccines, and cosmetic active ingredients, allowing them to enter various layers of the skin or be absorbed through skin capillaries / lymphatic vessels into the systemic bloodstream. It can be used for local or systemic drug administration, and can also be used in skin care cosmetics to increase the transdermal absorption of drugs and active ingredients.

[0005] However, there are still some problems with the use of microneedles and bone needles in existing technologies.

[0006] 1. The distance at which microneedles penetrate the skin is uncontrollable, which can easily puncture the stratum corneum and dermis, leading to bleeding and infection.

[0007] 2. The microneedling effect could not achieve the expected results, and the skin's absorption efficiency was poor.

[0008] 3. Applying solutions containing bone needles directly to the skin by hand can cause a stinging sensation, and direct contact poses a health and safety hazard. Summary of the Invention

[0009] This invention provides a method for promoting the absorption of beauty serums, thus solving the aforementioned problems.

[0010] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0011] A method for promoting the absorption of a beauty serum, characterized by comprising the following steps:

[0012] S1. Install the container containing the solution with bone needles onto the spraying equipment;

[0013] S2. The solution containing bone needles is sprayed onto the skin using a spraying device. The bone needles pierce the stratum corneum of the skin and remain on the skin.

[0014] S3. Apply the serum to the skin and use the applicator to deliver the serum into the skin.

[0015] Furthermore, the bone needles use four-axis needles, which can more effectively pierce the stratum corneum of the skin while reducing damage to the skin and improving the permeability and absorption efficiency of the serum.

[0016] Furthermore, the four-axis needle includes a main shaft with a length of 250-350 micrometers.

[0017] Furthermore, the quadcopter also includes three slave axes, each with a length of 50-100 micrometers.

[0018] Furthermore, the automatic detachment time of the bone needle is a, where 9 hours < a < 30 hours.

[0019] Furthermore, the content of bone needles in the solution is 5%-16%.

[0020] Furthermore, the solution includes acrylic acid and propylene ester / C10-30 alkanol acrylate crosslinked polymers. Due to their easy dispersibility, these polymers can produce excellent thickening efficiency, suspension capacity, long-term viscous flow characteristics, and crystal-clear transparency in gel systems. The crosslinked structure of the polymer can increase its viscosity, enabling the bone needles to be better suspended in the solution.

[0021] Furthermore, the spraying equipment has a spraying pressure of 400kp-1000kp, and the equipment has a large pressure adjustment range to adapt to different application scenarios and needs.

[0022] Furthermore, the spray device can adjust the amount of solution sprayed, which ensures that the solution with the bone needle is sprayed evenly onto the skin, avoiding waste and overuse. For different skin types and needs, the spray device can adjust the spray volume as needed to provide a personalized skin care experience.

[0023] Furthermore, the container can be disassembled and connected to the spraying equipment, increasing the equipment's reusability and reducing costs.

[0024] The present invention, by adopting the above-described technical solution, has the following beneficial effects:

[0025] This invention provides a method for promoting the absorption of beauty serum, which can improve the absorption efficiency of the serum; the bone needle will not pierce the epidermis and enter the dermis, so it will not cause infection or bleeding pain, and will not damage the skin; it reduces the risk of infection and improves safety; when manually applying the solution, the massage is very painful, while the spray method can both puncture and greatly reduce pain, while avoiding direct contact between the hand and the skin, making it safer.

[0032] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0034] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

[0035] like Figures 1 to 5 As shown, the present invention provides a method for promoting the absorption of a beauty serum, comprising the following steps:

[0036] S1. The seaweed sample (Callyspongia sponge) was subjected to ultrasonic oscillation and water washing to remove organic matter and carbonate minerals. It was then washed with pure water until neutral, followed by heavy liquid separation, dispersant washing, and drying to obtain siliceous spicules. Figure 5 and Figure 4 As shown, the bone needle is tetraaxial in shape and is formed through natural extraction.

[0037] S2. The extracted bone needles are mixed with the solution, which includes hydrolyzed sponge (bone needles), glycerin, and acrylate / C10-30 alkanol acrylate crosspolymer or glycerin and other ingredients. The other ingredients are determined according to the different effects of the beauty serum. Different beauty serums contain different ingredients. In the beauty serum, acrylate or glycerin / C10-30 alkanol acrylate crosspolymer can produce excellent thickening efficiency, suspension ability, long viscosity flow characteristics and crystal-clear transparency in the gel system. Its presence makes the solution viscous, so that the bone needles are suspended in the solution. The mixed solution containing bone needles is collected through a container.

[0038] like Figure 2 The experimental data show that

[0039] The insulin penetration rate in the group treated with 1% intravenous insulin was 1.65% ± 0.33%.

[0040] The insulin penetration rate in the group treated with 3% intravenous insulin was 3.39% ± 0.53%.

[0041] The insulin penetration rate in the group treated with 5% intravenous insulin was 18.5% ± 0.56%.

[0042] The insulin penetration rate in the group treated with 10% intravenous insulin was 34.48% ± 0.63%.

[0043] The insulin penetration rate in the group treated with 16% intravenous insulin was 54.38% ± 0.7%.

[0044] The insulin penetration rate in the group treated with 20% intravenous insulin was 56.52% ± 0.84%.

[0045] The insulin penetration rate in the group treated with 30% intravenous insulin was 59.81% ± 1.05%.

[0046] Based on the above data, when the content of the needle in the solution reaches 5%, the insulin permeability increases significantly. When the content of the needle exceeds 16%, the increase in permeability decreases. Therefore, considering both cost and effectiveness, the optimal ratio of the needle content in the solution is 5%-16%.

[0047] S3. Install a container containing a solution with bone needles onto a spraying device. The spraying device can be, for example, the applicant's application number 2024201378596 filed on January 19, 2024, which discloses a beauty device handle for air pressure spraying, or any existing device with the same effect. The spraying device can atomize the solution in the container so that the solution is sprayed out in an atomized state. The container can be detached and connected to the spraying device, which improves the reusability of the device and reduces costs.

[0048] S4. The solution containing bone needles is sprayed onto the skin using the spray device. Due to the unique shape of the bone needles, manual massage of the solution can cause a stinging sensation. The spray device uses pneumatic spraying to avoid direct skin contact, reducing the risk of infection and minimizing stinging. The spray pressure ranges from 400kp to 1000kp, offering a wide pressure adjustment range to adapt to different application scenarios and needs. The spray device can adjust the solution spray volume to ensure that serums and beauty essences are evenly sprayed onto the skin, avoiding waste and overuse. For different skin types and needs, the spray device can adjust the spray volume as required to provide a personalized skincare experience.

[0049] The four-axis needle consists of one main axis and three secondary axes. The main axis is 250-350 micrometers long, and the secondary axes are 50-100 micrometers long. The four-axis needle can more effectively pierce the stratum corneum of the skin. When one of the main or secondary axes pierces the skin, the other three axes will restrict the position of the axis that pierces the skin, preventing it from piercing the epidermis and entering the dermis. Therefore, it will not cause infection, bleeding, or pain, while reducing damage to the skin and improving the permeability and absorption efficiency of the serum. The bone needle pierces the stratum corneum of the skin and stays on the skin.

[0050] like Figure 3 As shown in the data obtained from the experiment, the insulin permeability of the group using the tape peeling method reached 63.24% ± 1.09%, which was the highest among all groups. However, this method is troublesome to operate and causes significant damage to the skin, so it has no practical value.

[0051] After treatment with 16% flying needles (bone needles), the penetration rate of the massage-introduced group was 54.38% ± 0.7%, indicating good absorption. The effects of flying needles are: firstly, the operator does not have direct contact with the skin through their hands, reducing the risk of infection; secondly, due to the depth, the flying needles only pierce the stratum corneum, so there is no risk of bleeding or infection, and there is basically no pain.

[0052] The permeability of the microneedling treatment group was 3.65% ± 0.58%. Both microneedling and microneedling rollers carry the risk of bleeding and infection because the pressure applied by microneedling rollers varies from person to person, and their absorption efficiency is much lower than that of microneedling rollers.

[0053] The insulin permeability of untreated skin was 0.6% ± 0.26%, indicating that insulin could hardly pass through the skin normally. Based on the above experimental data, it can be concluded that using bone needles can significantly increase skin absorption efficiency and reduce skin damage.

[0054] S5. Apply the serum to the skin surface. The serum can be a cosmetic solvent with different effects available in existing technology. The serum is then introduced into the skin through an importer (the importer is a product available in existing technology, and a low-frequency ultrasound import probe can be used to import the product).

[0055] S6. After the essence is introduced, the skin will automatically absorb it. The time that the bone needle stays on the skin surface (the time it falls off) is a. 9 hours < a < 30 hours. When this value is reached, the stratum corneum with the bone needle falls off, that is, the bone needle falls off automatically.

[0056] The above are merely specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on the present invention to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of the present invention.
