Description

The present invention relates to a gel nail application method.

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

One method for fixing gel nails to nails is to use a fixing agent. This method involves applying a gel nail containing a fixing agent with strong adhesive power, such as acrylic acid, to the surface of the nail to increase adhesion between the nail and the gel nail (see, for example, Patent Document 1), or applying a primer (a liquid agent that increases adhesion to the nail, also known as a base agent) before applying the gel nail. According to the treatment method described in Patent Document 1, since acrylic acid contains carboxyl groups in its molecules, it is thought that this can 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.

Another method for fixing gel nails to the nail involves sanding the surface of the nail, allowing the base gel to penetrate into the unevenness of the nail, creating an anchoring effect and fixing the gel nail in place (see, for example, Patent Document 2).

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 types of gel.

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

However, when removing old gel nails, if the gel nails were fixed using a fixative or primer, the fixative penetrates into the surface of the nail and chemically bonds to it. Therefore, the gel nail is softened using 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 and then filed off, and the surface of the nail is then filed down to form a new gel nail. Whichever method is used, there is a risk that the nail will become thinner each time a gel nail is formed.

The objective of the present invention is to provide a gel nail application method that can remove gel nails without damaging the nails and that allows gel nails to last longer than if this application method is not used.

Embodiments of the present invention will be described below with reference to the drawings. Note that in each drawing, components having substantially the same functions are designated by the same reference numerals, and redundant explanations will be omitted.

Figure 1 is a cross-sectional view showing the state of a fingernail with gel nail applied, seen from the fingertip side. The nail 2 of finger 1 has 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 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 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.

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 an example of a gel nail resin. The base gel 31 is an example of the bottom layer. The gel nail 3 may also consist of two layers or four or more layers. For example, the top gel 33 may be applied on top of the base gel 31 without applying the color gel 32. In this case, the base gel 31 is often transparent, and removing only the top gel 33 requires skill.

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

(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 fixative 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.

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 from 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 from 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, loose cuticle 25, keratinous material such as keratin flakes from the surface 2a of the nail 2, and loose hyponychium 27, keratinous material such as keratin flakes from the back surface 2b of the nail 2, using a pusher while using the nail serum as a lubricant, without scraping 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.) from the front surface 2a and back surface 2b of the nail 2 to clean and smooth it.

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 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, it becomes possible to remove the base gel 31 without causing pain to the nail 2. If the fourth step is performed without the third step, friction will occur between the dried and hardened nail 2 and the pusher, potentially 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, reducing the risk of pain to the nail 2. The "keratinous material" in the fourth step includes, for example, keratinous pieces separated from the loose cuticle 25 and loose hyponychium 27, and keratinous pieces separated from the nail 2. By performing 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 improving the bonding strength.

Gel nail removers swell the base gel 31 (e.g., soft gel) and lift it from the nail 2, and commercially available removers include those containing acetone (solvent) and those that are acetone-free. Acetone has the ability to dissolve resins and other substances, making it easy to remove gel nails, but it has the disadvantage of drying out fingers and nails and making nails more prone to cracking, so acetone-free removers are preferable for protecting and nurturing nails.

(Nail serum composition)
A nail beauty serum that has, for example, the effect of softening the skin epidermis, is permeable to the skin, moisturizes, and is lubricating. The lubricating properties act as a lubricant for the metal pusher, making it easier to peel off the gel nail 3 with little force, and thus play an important role in the gel nail removal process. For example, a cuticle remover or the like may be used as such a nail beauty serum.

The nail serum used in this embodiment may contain, for example, water, BG (butylene glycol), glycerin, PEG-7 glyceryl cocoate, olive fruit oil, tocopherol, hydrolyzed collagen, sodium hyaluronate, hydrolyzed keratin, hawthorn extract, jujube fruit extract, grapefruit fruit extract, apple fruit extract, orange juice, lemon juice, lime juice, DPG (dipropylene glycol), (acrylates/C10-30 alkyl acrylate) crosspolymer, polysorbate 20, potassium hydroxide, phenoxyethanol, methylparaben, and lavender oil (e.g., PCN Cuticle Treatment manufactured by Super Ion 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 breakage of nails. 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 ingredients of the nail serum are not limited to those listed above, and other ingredients may be used as long as they have similar effects.

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 through their keratin-softening action, thereby ultimately lifting the gel nail 3 from the nail 2. This led to the inventors' discovery that this cuticle remover can be used 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.

(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 Figures 3 to 6. Figure 3 is a cross-sectional view schematically showing the process of removing a gel nail. Figure 4 is a cross-sectional view schematically showing the process of preparation before applying a gel nail. Figure 5(a) is a cross-sectional view of a main part schematically showing the process of preparation before applying a gel nail, and Figure 5(b) is a view of Figure 5(a) from the back side. Figure 6 is a cross-sectional view schematically showing the process of applying a gel nail.

(1) Gel nail removal (gel nail removal process)
The gel nail 3 is removed in the following order.

(a) The surface of the old applied 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, for example, aluminum foil.

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

(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 blade. First, remove the gel nail 3 from the area where the gel nail 3 is peeling 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 force. 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. Metal pushers 4A and 4B are an example of a pusher. Other pushers may also be used, for example, ceramic pushers, wooden sticks, cotton swabs, etc.

(e) Remove the base gel 31 from all 10 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 when doing this. Note that a ceramic pusher, wood stick, cotton swab, etc. may also be used instead of the metal pusher 4A.

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

(b) Push-up: 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 radially. 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. Therefore, it is necessary to remove the loose hyponychium 27, especially near the tip of the nail.

(c) Peeling (exfoliation)
Peeling (keratin care) is performed using a specially designed metal pusher 4A to remove keratin flakes present under the loose cuticle 25 on the surface 2a of the nail 2 and keratin flakes present under the loose hyponychium 27 on the back surface 2b. If 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, resulting in a shortened lifespan of the gel nail 3. Therefore, removing the keratin flakes is an important task. 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.

(3) Preparation process before applying gel nails
Prepare before applying gel nails in the following order:

(a) Wet a special cloth (for example, Hadapi Kaigo, manufactured by Nachihama Co., Ltd.) with water and wipe off oil and other deposits (dirt, dust, dead skin, etc.) from the front surface 2a and back surface 2b of the nail 2 to clean (purify) and smooth (smooth) the front surface 2a and back surface 2b of the nail 2. The special cloth is made of cloth fabric coated with fine 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.

Figure 7 is a close-up photograph of the surface 2a of the thumb nail 2. Figure 7(a) is a photograph taken immediately after peeling the thumb, and Figure 7(b) is a photograph taken immediately after wiping the surface 2a of the nail 2 with a special 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 special cloth, the dead skin cells on the surface 2a of the nail 2 are removed, making it even smoother.

Figure 8 is a close-up 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 cuticle 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 is somewhat smoother. However, after wiping away dead skin and other debris 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 is even smoother. Therefore, the degree of smoothness of the surface 2a of the nail 2 serves as a guide for how far to wipe with a specific cloth.

(b) Remove any cuticles, thin skin, and small nails remaining around the cuticle 24 using cuticle nippers.
(c) The nail 2 is shaped with an emery board, and the back of the nail is deburred with a sponge buffer, as shown in FIG. 5, and an inclined surface 2d is formed between the tip surface 2c and the back surface 2b of the nail 2.

(4) Applying base gel (gel nail formation process)
First, a pre-primer, an oil-removing solvent such as anhydrous ethanol, or the like is applied to the entire nail 2 (front surface 2a, back surface 2b, tip surface 2c, and inclined surface 2d) using a brush or the like 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 lamp) 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.

(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.

(6) Applying Top Gel 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 to the front surface 2a of the nail 2 but also to the back surface 2b.

To extend 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 it 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 from the nail 2, bacteria such as Pseudomonas aeruginosa can enter the gap, leading to unsanitary conditions. This can be prevented. Note that the amount of color gel 32 applied can be small, as long as it produces color. Furthermore, even when a two-layer structure of base gel 31 and top gel 33 is used without using color gel 32, it is preferable to apply the base gel 31 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. Furthermore, since the base gel 31, color gel 32, and top gel 33 are prone to peeling if they get onto the back surface 2b of the nail 2, it is preferable that they do not get onto the back surface 2b.

(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 SHAREDOWA TRELLYAN manufactured by Medical Arc Co., Ltd. was used as the gel nail remover 5. Then, in Example 1, PCN Cuticle Treatment manufactured by Superion 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 distal end surface 2c and the rear surface 2b of the nail 2, and the gel nail 3 was applied not only to the distal end surface 2a and the distal end surface 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 distal end surface 2c and the rear surface 2b of the nail 2, and the gel nail 3 was applied to the distal end surface 2a and the distal end surface 2c of the nail 2. In addition, in Examples 1, 2, and the conventional example, soft gel was used as the gel nail 3.

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.

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

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 nails lasted even longer than with the treatment method of Example 2.

(Functions and Effects of the Embodiments)
According to this embodiment, the following actions and effects are achieved.
(1) Since 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. Therefore, the base gel 31 can be removed with only a slight force on the metal pusher 4A, and 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 grow nails and keep them healthy.

Note that the present invention is not limited to the above-described embodiment, and various other embodiments are possible. For example, while the above-described embodiment describes a case in which a gel nail treatment method is applied to fingernails, the gel nail treatment method may also be applied to toenails.

The above describes an embodiment of the present invention, but the present invention is not limited to the above embodiment and various modifications and implementations are possible. For example, in the above embodiment, the gel nail application method was described as including a gel nail removal process, a preparation process, and a gel nail formation process. However, even if gel nails are not used, it is possible to perform only the gel nail removal process and all or part of the preparation process to grow damaged nails and keep them healthy.
