Description

[Technical Field]

[0001] The present invention relates to a gel nail application method. [Background technology]

[0002] In recent years, a treatment method has become known in which gel nails (artificial nails) are formed by applying a gel-like resin to the nails and hardening it in order to make the fingertips look beautiful.

[0003] One method for fixing gel nails to nails uses a fixative. This method involves applying a gel nail containing a fixative with strong adhesive power, such as acrylic acid, to the surface of the nail to enhance adhesion between the nail and the gel nail (see, for example, Patent Document 1). Another method involves applying a primer (a liquid agent for enhancing adhesion to the nail, also known as a base coat) before applying the gel nail. According to the treatment method described in Patent Document 1, acrylic acid contains a carboxyl group in its molecule, which is thought to chemically improve the adhesive strength of the cured coating film (gel nail) to the substrate (nail), resulting in the formation of a cured coating film (gel nail) with excellent adhesiveness.

[0004] Another method for fixing gel nails to nails is to sand the surface of the nail, allowing the base gel to penetrate into the unevenness of the nail, thereby exerting an anchoring effect and fixing the gel nail (see, for example, Patent Document 2).

[0005] Gel nails come in three types: hard gel (mainly composed of acrylic resin, for example), soft gel (mainly composed of urethane, polyurethane, polyvinyl, etc.), and semi-hard gel, and the above two fixing methods are used for all gels. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Patent Application Publication No. 2024-177722 [Patent Document 2] Japanese Patent Application Publication No. 2025-025560 Summary of the Invention [Problem to be solved by the invention]

[0007] Over time, gel nails deteriorate, discoloring and developing surface irregularities due to moisture evaporation and penetration. Over time, not only do gel nails themselves deteriorate, but they can also loosen from their original adhesion to the nail or chip. To prevent gel nails from peeling from the nail, they are typically applied not only to the surface but also to the tip of the nail. However, this can wear off and damage the exposed nail. Therefore, to keep your fingertips looking beautiful, it's necessary to periodically remove old gel nails and apply new ones.

[0008] However, when removing old gel nails, if the gel nails were fixed using a fixative or primer, the fixative penetrates the surface of the nail and chemically bonds to it. Therefore, the gel nail is softened with a gel nail remover (also called a remover), and the softened gel nail is then filed off along with the surface of the nail using a metal pusher or washable file. Even for gel nails formed by sanding the surface of the nail, the gel nail is often softened, filed off, and then the surface of the nail is filed down to form a new gel nail. Regardless of which method is used, there is a risk that the nail will become thinner each time a gel nail is formed.

[0013] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings, components having substantially the same functions are designated by the same reference numerals, and redundant description thereof will be omitted.

[0014] FIG. 1 is a cross-sectional view showing a state in which gel nails have been applied to the fingernails, as seen from the fingertip side. The structure of the nail 2 of the finger 1 is a three-layer structure consisting of, from the finger 1 side, the ventral nail (also called the underplate) 21, the central nail (also called the middle plate) 22, and the dorsal nail (also called the top plate) 23. The ventral nail 21 and the dorsal nail 23 have keratin that runs vertically (the length of the finger), while the central nail 22 is thicker than the ventral nail 21 and the dorsal nail 23 and has keratin that runs horizontally. The gel nail 3 is applied to the surface 2a of the dorsal nail 23, etc.

[0015] Gel nails 3 generally consist of a base gel 31 applied to the back nail 23, a color gel 32 applied on top of the base gel 31, and a top gel 33 applied on top of the color gel 32. A design may also be applied when applying the color gel 32. The base gel 31, color gel 32, and top gel 33 are examples of the multiple layers that make up the gel nail 3 and are examples of gel nail resins. The base gel 31 is an example of the bottom layer. The gel nail 3 may also consist of two or four or more layers. For example, the top gel 33 may be applied on top of the base gel 31 without the color gel 32. In this case, the base gel 31 is often transparent, and removing only the top gel 33 requires skill.

[0016] FIG. 2 is a cross-sectional view showing a fingernail with gel nail applied, as seen from the side. A cuticle (also called cuticle or cuticle cuticle) 24 is formed around the base of the nail 2, and a loose cuticle (also called cuticle cuticle keratin) 25 is formed between the nail 2 and the cuticle 24. A loose hyponychium (also called hyponychium keratin) 27, which originates from a hyponychium (also called hyponychium) 26, is formed on the underside 2b of the nail 2. The loose cuticle 25 originates from the cuticle 24 and is a thin layer of keratin attached to the surface 2a of the nail 2, and extends toward the tip of the nail 2 as the nail 2 grows. The loose hyponychium 27 is a thin layer of keratin attached to the underside 2b of the nail 2, and extends toward the tip of the nail 2 as the nail 2 grows.

[0017] (Overview of treatment method) The gel nail application method according to this embodiment involves removing the old gel nail 3, which consists of multiple layers formed on the surface 2a of the nail 2, without scraping the nail 2, and then forming a new gel nail 3 on the nail 2 by utilizing intermolecular bonds between the nail 2 without using a fixing agent or primer. In other words, this gel nail application method applies room-temperature bonding technology, which bonds thin metal films together at room temperature without using adhesive. Room-temperature bonding technology is a technology that bonds thin films together by utilizing intermolecular bonds. "Removing without scraping the nail 2" means that some scraping of the nail 2 is acceptable.

[0018] The removal of the old gel nail 3 preferably includes the following steps: a first step of scraping and removing the old gel nail 3 so that the base gel 31 remains; a second step of applying a gel nail remover that swells the base gel 31 and lifts it off the nail 2; a third step of applying a moisturizing and lubricating nail serum between the surface 2a of the nail 2 and the base gel 31 that has lifted off the nail 2, and to the back surface 2b of the nail 2, thereby moisturizing the dried nail 2 with the gel nail remover; and a fourth step of removing the base gel 31, the loose cuticle 25, keratinous material such as keratin flakes on the surface 2a of the nail 2, and the loose hyponychium 27, keratinous material such as keratin flakes on the back surface 2b of the nail 2, with a pusher while using the nail serum as a lubricant, so as not to scrape the nail 2. Furthermore, after removing the old gel nail 3, and before forming a new gel nail 3, it is preferable to further include a preparation step of wiping off oil and other deposits (e.g., dirt, dust, dead skin cells, etc.) on the surface 2a and back surface 2b of the nail 2 to clean and smooth it.

[0019] In the first step, by filing the gel nail so that only the bottom layer of base gel 31 remains, the base gel 31 is more likely to lift compared to applying a gel nail remover without filing the gel nail at all. In the first step, "filing so that only the bottom layer of base gel 31 remains" includes leaving only the base gel 31 to the extent that only the surface of the base gel 31 is filed away. The method of leaving only the bottom layer of base gel 31 is known as fill-in (leaving one layer). In the second step, by lifting the base gel 31 from the nail 2, the base gel 31 can be removed without causing pain to the nail 2. If the fourth step is performed without the third step, friction may occur between the dried and hardened nail 2 and the pusher, causing pain to the nail 2. In the third step, by applying a nail serum, the serum acts as a lubricant between the nail 2 and the tip of the pusher, making it less likely that pain will occur to the nail 2. The "keratinous material" in the fourth step includes, for example, pieces of keratin separated from the loose cuticle 25 and the loose hyponychium 27, and pieces of keratin separated from the nail 2. By carrying out the preparation step, the surface 2a of the nail 2 becomes smooth, increasing the contact area between the surface 2a of the nail 2 and the new gel nail, and increasing the bonding strength.

[0020] Gel nail removers have the effect of swelling the base gel 31 (e.g., soft gel) and lifting it from the nail 2, and commercially available removers include those containing acetone (solvent) and those that are acetone-free. Acetone has the effect of dissolving resins and the like, which has the advantage of making it easy to remove gel nails, but the disadvantage is that it dries out fingers and nails and makes nails more prone to cracking, so acetone-free removers are preferable for protecting and nurturing nails.

[0021] (Nail serum composition) A nail serum that has, for example, the effect of softening the skin epidermis, permeability to the skin, moisturizing properties, and lubrication properties is preferred. The lubricity of the serum acts as a lubricant for the metal pusher, making it easier to remove the gel nail 3 with little force, and thus plays an important role in the gel nail removal process. For example, a cuticle remover or the like may be used as such a nail serum.

[0022] The nail serum used in this embodiment may contain, for example, water, butylene glycol (BG), glycerin, PEG-7 glyceryl cocoate, olive oil, tocopherol, hydrolyzed collagen, sodium hyaluronate, hydrolyzed keratin, hawthorn extract, jujube fruit extract, grapefruit extract, apple extract, orange juice, lemon juice, lime juice, dipropylene glycol (DPG), acrylates / C10-30 alkyl acrylate crosspolymer, polysorbate 20, potassium hydroxide, phenoxyethanol, methylparaben, and lavender oil (e.g., PCN Cuticle Treatment manufactured by Superion Corporation), or may further contain hydrolyzed (Bifidobacterium / Enterococcus faecium / Lactobacillus / Streptococcus thermophilus) / fermented soy milk curd, hot spring water, lactose, and ethanol. BG has high moisturizing and penetrating properties. Glycerin prevents dry skin and provides moisturizing effects. PEG-7 glyceryl coconut oil fatty acid is a cleansing ingredient. Olive fruit oil has lubricating properties and prevents dryness, thereby preventing nail cracking. Tocopherol, a vitamin E, aids skin metabolism. Hydrolyzed collagen prevents dryness, moisturizes, and prevents cracks and breakages. Sodium hyaluronate moisturizes the skin. Hydrolyzed keratin protects, repairs, and strengthens nails. Hawthorn extract has antioxidant properties. The above three fruit extracts and three fruit juices are fruit-derived ingredients with skin-beautifying properties. DPG has moisturizing properties. The above crosspolymers and polysorbate 20 act as emulsifiers and solubilizers. Potassium hydroxide is used to break down and dissolve oily stains. Phenoxyethanol and methylparaben have antibacterial properties. Lavender oil promotes nail growth. The components of the nail beauty serum are not limited to those mentioned above, and other components may be used as long as they have similar effects.

[0023] The cuticle remover may contain, for example, water, liquid lanolin, potassium hydroxide, and carrageenan (e.g., Blue Cross, manufactured by Link Co.). Liquid lanolin is a liquid form of sheep's wool oil (lanolin) and has excellent skin penetration, moisturizing, and lubrication properties. Potassium hydroxide softens the skin's epidermis. Carrageenan is a polysaccharide extracted from red seaweed, and has a fluid viscosity, forming a weak, elastic gel. The inventors discovered that cuticle removers can soften the keratin that normally forms between the nail and the gel nail by their keratin-softening effect, thereby lifting the gel nail 3 from the nail 2, and therefore have made it usable as a remover for the gel nail 3. Note that the ingredients of the cuticle remover are not limited to those listed above; other ingredients with similar effects may be used.

[0024] (Specific examples of treatment methods) Next, an example of a treatment method from removing an old gel nail 3 to applying a new gel nail 3 will be described with reference to Figs. 3 to 6. Fig. 3 is a cross-sectional view schematically showing the process of removing a gel nail. Fig. 4 is a cross-sectional view schematically showing the process of preparation before applying a gel nail. Fig. 5(a) is a cross-sectional view of a main part schematically showing the process of preparation before applying a gel nail, and Fig. 5(b) is a view of Fig. 5(a) from the back side. Fig. 6 is a cross-sectional view schematically showing the process of applying a gel nail.

[0025] (1) Gel nail removal (gel nail removal process) Remove the gel nail 3 in the following order.

[0026] (a) The surface of the applied old gel nail 3 is scraped off with a gel nail removal tool (for example, a gold bit of a nail machine (at the recommended speed), a washable file, etc.) until the top gel 33 and color gel 32 are gone and the surface of the base gel 31 is scraped off, or until the base gel 31 is almost gone. (b) Next, cotton soaked in gel nail remover 5 is applied to the fingertips (one or two fingers at a time) according to the size of the nails 2. At this time, to prevent the nails 2 from drying out, the cotton is wrapped around the fingertips in aluminum foil, for example.

[0027] (c) Repeat step (b) above until you have completed all 10 fingers.

[0028] (d) After approximately 10 to 15 minutes have passed since the aluminum foil was wrapped around the nail, the aluminum foil is removed. Immediately return to the first nail and apply nail serum to the entire nail 2 (surface 2a, back surface 2b, and tip surface 2c) with a brush or similar tool. Then, as shown in Figure 3, remove the gel nail 3 (mainly the base gel 31) with a specially designed metal pusher 4A. The specially designed metal pusher 4A is a commercially available metal pusher 4B with a rounded edge. First, remove the gel nail 3 from the area where the gel nail 3 is beginning to peel toward the base of the nail 2 without applying too much force. The angle θ1 of the metal pusher 4A when removing the gel nail 3 is preferably approximately 20 to 30°. It is preferable to support the metal pusher 4A with the thumb and middle finger to avoid applying too much pressure. Because nail serum evaporates easily, it is important to frequently apply nail serum to the nail 2 to prevent the exposed surfaces, such as the surface 2a of the nail 2, from drying out. The metal pushers 4A and 4B are an example of a pusher. The pusher may be, for example, a ceramic pusher, a wooden stick, a cotton swab, or the like.

[0029] (e) Remove the base gel 31 from all ten nails using the metal pusher 4A. If there is still gel nail 3 remaining on the surface 2a of the nail 2, gently peel off the gel nail 3 using the oval carbide of the nail machine (rotation speed: approximately 5000 rpm). Be careful not to damage the nail 2. Note that a ceramic pusher, wood stick, cotton swab, etc. may be used instead of the metal pusher 4A.

[0030] (2) Nail care (a) Pour hot water into a finger bowl to soften the area around the cuticle 24 and both sides of the nail 2, and then dip the five fingertips of one hand into the hot water and lightly wipe them off. Repeat with the five fingers of the other hand.

[0031] (b) Push-ups Nail serum is applied to the entire nail (surface 2a, back surface 2b, and tip surface 2c). As shown in FIG. 4, a commercially available metal pusher 4B is applied to the loose cuticle 25 at a predetermined angle θ2 (e.g., 45 to 90°) to push the loose cuticle 25 toward the base of the nail 2 and remove it. The push-up is performed in a radial pattern. This also removes dead skin cells attached around the sideline (arising from the sidewall). Similarly, the loose hyponychium 27 is removed by pushing it toward the hyponychium 26. If the loose hyponychium 27 is not removed, depending on the degree of growth of the loose hyponychium 27, it may cause a decrease in the holding power of the gel nail 3, so it is necessary to remove the loose hyponychium 27, especially near the tip of the nail.

[0032] (c) Peeling (exfoliation) Peeling (keratin care) is performed using a specially designed metal pusher 4A to remove the keratin flakes present under the loose cuticle 25 on the surface 2a of the nail 2 and the keratin flakes present under the loose hyponychium 27 on the back surface 2b. If the gel nail 3 is applied without removing the keratin flakes present under the loose cuticle 25 and loose hyponychium 27, the contact area between the gel nail 3 and the nail 2 will be reduced, causing the gel nail 3 to last less long, so removing the keratin flakes is an important step. Peeling is performed sequentially on the surface 2a and back surface 2b of the nail 2 while applying nail serum to the surface 2a and back surface 2b of the nail 2 to keep them moisturized. Immediately after peeling, nail serum is also applied to the surface 2a and back surface 2b of the nail 2.

[0033] (3) Preparation before applying gel nails Prepare before applying gel nails in the following order:

[0034] (a) Wet a special cloth (for example, Hadapi Kaigo made by Nachihama Co., Ltd.) with water and wipe off oil and other deposits (dirt, dust, dead skin, etc.) from the surface 2a and back surface 2b of the nail 2 to clean (purify) and smooth (smooth) the surface 2a and back surface 2b of the nail 2. The special cloth is made of cloth fabric coated with rubber particles, and can remove oil stains using only water. Note that other fabrics such as microfiber cloth may be used instead of the special cloth.

[0035] Figure 7 is a photograph of a magnified view of the surface 2a of the thumb nail 2. Figure 7(a) is a photograph taken immediately after peeling of the thumb, and Figure 7(b) is a photograph taken immediately after wiping the surface 2a of the nail 2 with a specific cloth. The surface 2a of the nail 2 is somewhat smooth even immediately after peeling, but it can be seen that by wiping the surface 2a of the nail 2 with a specific cloth, the dead skin cells on the surface 2a of the nail 2 are removed, making it even smoother.

[0036] Figure 8 is a magnified photograph of the surface 2a of the index finger nail 2. Figure 8(a) is a photograph after the gel nail 3 has been removed, Figure 8(b) is a photograph immediately after peeling, and Figure 8(c) is a photograph immediately after wiping the surface 2a of the nail 2 with a specific cloth. After the gel nail 3 has been removed, the surface 2a of the nail 2 appears rough due to the presence of loose cuticles 25. Immediately after peeling, the yellow line (also known as the yellow line, the arc-shaped part in the photograph) becomes more visible, and the surface 2a of the nail 2 appears somewhat smoother. However, after wiping away dead skin cells with a specific cloth, there is almost no change in the appearance of the yellow line, but it can be seen that the surface 2a of the nail 2 has become even smoother. Therefore, the degree of smoothness of the surface 2a of the nail 2 serves as a guide for determining how far to wipe with a specific cloth.

[0037] (b) Use cuticle nippers to remove any cuticles, thin skin, and small nails remaining around the cuticle. (c) The nail 2 is shaped using an emery board, and the underside of the nail is deburred using a sponge buffer, as shown in Figure 5, while forming an inclined surface 2d between the tip surface 2c and the back surface 2b of the nail 2.

[0038] (4) Applying base gel (gel nail formation process) First, a pre-primer, anhydrous ethanol, or other oil-removing solvent is applied to the entire nail 2 (front surface 2a, back surface 2b, tip surface 2c, and inclined surface 2d) using a brush or similar to remove oil from the nail 2. Next, a base gel 31 is applied to the front surface 2a, tip surface 2c, and inclined surface 2d of the nail 2 using a brush. Next, the base gel 31 is cured by irradiating it with light appropriate for the base gel 31. Examples of light appropriate for the base gel 31 include LED (light-emitting diode) light, UV (ultraviolet) light, and CCFL (cold cathode fluorescent light). The light is applied to the nail 2 not only from the front surface 2a side but also from the back surface 2b side.

[0039] (5) Applying color gel A design is created by applying color gel 32 with a brush onto the hardened base gel 31. Next, the color gel 32 is hardened by irradiating it with light appropriate for the color gel 32. Examples of light appropriate for the color gel 32 include LED light, UV light, and CCFL light. The light is applied to the nail 2 from both the front surface 2a and the back surface 2b.

[0040] (6) Applying top gel A top gel 33 is applied with a brush onto the cured color gel 32. Next, the top gel 33 is cured by irradiating it with light appropriate for the top gel 33. Examples of light appropriate for the top gel 33 include LED light, UV light, and CCFL light. The light is applied not only from the front surface 2a of the nail 2 but also from the back surface 2b.

[0041] To prolong the life of the gel nail 3, it is preferable to apply the base gel 31, color gel 32, and top gel 33 not only to the surface 2a and tip surface 2c of the nail 2 but also to the inclined surface 2d, as shown in Figure 6. In other words, applying the gel nail 3 to the inclined surface 2d as well as the surface 2a and tip surface 2c improves the holding power (grip strength) of the gel nail 3 and makes the gel nail 3 less likely to peel off from the nail 2 than when the gel nail 3 is applied only to the surface 2a and tip surface 2c. Furthermore, compared to when the gel nail 3 is applied only to the surface 2a and tip surface 2c of the nail 2, moisture and other substances are less likely to penetrate between the surface 2a of the nail 2 and the gel nail 3, making the gel nail 3 less likely to peel off from the nail 2 and lasting longer. Furthermore, if the gel nail 3 lifts off the nail 2, bacteria such as Pseudomonas aeruginosa can enter the gap, leading to unsanitary conditions. However, this can be prevented. Note that the amount of color gel 32 applied can be small, as long as it is colored. Furthermore, even when a two-layer structure of base gel 31 and top gel 33 is employed without using color gel 32, it is preferable to apply base gel 31 and top gel 33 not only to the surface 2a and tip surface 2c of nail 2, but also to the inclined surface 2d. Furthermore, since the base gel 31, color gel 32, and top gel 33 tend to peel off easily if they reach the back surface 2b of nail 2, it is preferable that they do not reach the back surface 2b.

[0042] (Example) Table 1 shows the results of interviews with 10 subjects regarding the presence or absence of pain. In Examples 1 and 2, acetone-free gel nail remover 5 was used, manufactured by Medical Arc Co., Ltd. (Shared D'Oir Trell Yarn). Then, in Example 1, PCN Cuticle Treatment by Super Ion Co., Ltd. was used as the nail serum, and in Example 2, a cuticle remover was used instead of the nail serum. In the conventional example, the gel nail 3 remaining on the surface of the nail 2 was removed using a metal pusher 4B without using the gel nail remover 5, nail serum, or cuticle remover. In Example 1, an inclined surface 2d was formed between the leading edge 2c and the rear surface 2b of the nail 2, and the gel nail 3 was applied not only to the leading edge 2a and leading edge 2c of the nail 2 but also to the inclined surface 2d. In Example 2 and the conventional example, the inclined surface 2d was not formed between the leading edge 2c and the rear surface 2b of the nail 2, and the gel nail 3 was applied to the leading edge 2a and leading edge 2c of the nail 2. In addition, in Examples 1, 2, and the conventional example, soft gel was used as the gel nail 3.

[0043] [Table 1]

[0044] As shown in Table 1, with the treatment methods of Examples 1 and 2, none of the 10 people felt pain, whereas with the conventional treatment method, 9 out of 10 people felt pain.

[0045] Table 2 shows the results of interviews with three subjects regarding the durability of the gel nail 3. The durability is the time from when the gel nail 3 is applied to the nail 2 until a part of the gel nail 3 peels off. [Table 2]

[0046] As shown in Table 2, with the conventional treatment method, the gel nails 3 lasted only one or two weeks, but with the treatment methods of Examples 1 and 2, the gel nails 3 lasted more than twice as long as with the conventional treatment method. With the treatment method of Example 1, the lasting time was even longer than with the treatment method of Example 2.

[0047] (Actions and Effects of the Embodiments) According to this embodiment, the following actions and effects are achieved. (1) Because the gel nail is formed by utilizing the intermolecular bond between the nail and the gel nail without using a fixative or primer and without sanding the nail, the gel nail can be removed without damaging the nail, and the gel nail can last longer than if this treatment method is not used. (2) When removing the old gel nail 3, the base gel 31 remaining on the surface 2a of the nail 2 is swelled and lifted off the nail 2 using the gel nail remover 5, and then a lubricating nail serum is applied to the surface 2a and back surface 2b of the nail 2. This allows the base gel 31 to be removed with only a slight force on the metal pusher 4A, so the gel nail 3 can be removed without causing much pain to the person receiving the treatment. (3) By forming an inclined surface 2d on the tip side of the nail 2 and applying gel nail 3 not only to the surface 2a and the tip surface 2c but also to the inclined surface 2d, the tip side of the gel nail 3 does not lift, peel, or chip, and the gel nail 3 lasts longer. (4) Nail serums contain not only moisturizing ingredients, but also various beauty ingredients such as ingredients that moisturize the skin, ingredients that repair, protect, and strengthen nails, ingredients that have skin-beautifying effects, and ingredients that promote nail growth, so they can help grow nails and keep them healthy.

[0048] The present invention is not limited to the above-described embodiment, and various other embodiments are possible.
