What's Nail Extension?

Nail extensions are basically false nails. This is a fashionable accessory worn on the nails. 

Even if your nails are short, you can do nail extensions because the nail extensions maybe longer. 

For those with shorter nails, nail extensions can help you get longer nails instead of actually letting them grow out. 

These extensions come in several shapes and sizes. However, in order to ensure that your extension is in the best condition, you still need to pay attention. 

Some people suggest that you check it every two weeks. Nail extensions are also often longer than other manicures.

What's good about nail extensions?

---

Advantage

• Acrylic extensions are suitable for women with fragile nails.

• Acrylic is good for women, they have the habit of chewing nails because nails are difficult to chew off.

• Acrylic nails have a longer history than similar products, so most nail technicians in salons and spas have extensive experience in how to apply and remove these nails.

• You don't have to worry about such side effects.

• They last longer than gel nails.

Disadvantage

• If they are not removed properly, they can damage your natural nails.

• Because acrylic nails are artificial, they present a fake look. You need a very talented technician who can bring your acrylic resin close to nature.

• The use of acrylic nails involves the use of strong chemicals and the formation of fumes. Some women may be allergic to these substances.

• You need to renew every month, which means additional expenses.

Can you use regular nail polish with gel top coat？

You can use top coat on ordinary nail polish, Before doing this you must polish the surface of the nail, the human real nail surface is smooth, and greasy, must use sanding hair, or nail polish may not stick firmly, and easy to fall off.

Detailed operation steps are:

After grinding the nail surface, dusting with a dusting brush, and then use a cotton pad with a certain amount of cleaning liquid to clean the nail surface. It is also important to note that if you do the hand care first and then cure it, if you do not apply sunscreen, it is more likely to lead to skin aging.

But in fact, for ordinary nail polish, you don’t need to do so 

nail polish is easy to cracking after curing it. The step of applying a layer of top coat is specifically for gel polish, which is difficult to dry in natural conditions, while ordinary nail polish can dry in natural conditions easily. The difference between gel polish and regular nail polish is that gel polish lasts longer and can make more beautiful shapes, and by saving the time to dry by curing, gel polish occupies the majority of the nail art market. It would be a better choice.

The steps to use gel polish for manicure are as follows.

1. First trim the nails, clean the dead skin around the nails, and then use a nail file to polish off the grease layer on the surface of the nails, so that the base gel and nails fit more closely. You can use primer as well.

2. Use the base coat, cure it, then use the color gel, every time you apply it, cure it once, after two times if you think the color is suitable, then you can carry out the top coat, if you think the color effect is not good, you can apply the third time.

3.Choose the type of top coat according to your preference and needs. After applying the top coat, cure it and let the it dry thoroughly so that all the steps are finished. Usually gel polish needs to be removed after 2~3 weeks. When removing, first grind off the top coat and then use nail remover to handle it, avoid picking nails by yourself.

There are also people asking: Can clear nail polish be used as top coat?

The answers is: No! Clear nail polish can't be used as top coat. Transparent nail polish does not have the ability to fix gel polish and is not as strong as gel polish, gel polish has a strong adhesion after use on the nail, and transparent nail polish generally only has a shelf life of four or five days, so it is not suitable for use as top coat.

The point of top coat is to hold the gel polish in place so that it doesn't layer on the nail and crack easily, but obviously clear nail polish doesn't have that ability. The ingredients contained in the top coat are usually chemical based, so it is very strong, but after applying the top coat you need to cure it.

If it is ordinary clear nail polish in the process of curing, it’s very easy to crack. Clear nail polish can't be used as top coat, these two are not the same kind of product.

How to properly treat the fluorescent agent in nail products.

In this article, we are going to explain in detail about fluorescents and hopefully help all nail art lovers to dispel their worries

First of all, we have three questions to answer

1: What exactly is fluorescent agent?

Fluorescent agent, also known as fluorescent whitening agent, is a fluorescent dye, or white dye, and a complex organic compound. It absorbs ultraviolet light and emits blue-violet fluorescence, which is neutralized with the yellow light produced by the object absorbing ultraviolet light, making the painted object look white and achieving the purpose of whitening.

2: Is fluorescent agent harmful to health?

• Fluorescents are not irritating to the skin: After years of animal and human experiments, even fluorescent whitening products that come into direct contact with the skin are not irritating to the skin and do not cause skin allergies. And through daily washing actions, such as hand washing and bathing, it can be easily washed off completely and will not be absorbed into the skin.

• No adverse effects on wound healing: The article "Toxicological properties of fluorescent brighteners" published in the German Journal of Dermatology in 1994 pointed out that even if the use of textile materials containing fluorescent brighteners in direct contact with wounds, there will be no adverse effects on wound healing, and no pathological changes to human skin.

• Metabolism: Fluorescent whitening agents are water-soluble and can be excreted quickly and completely through normal metabolism.

  The book "Environmental Quality and Safety Supplement Volume IV 'Fluorescent Whitening Agents'" published by Georg Thieme, Germany, shows that fluorescent whitening agents can be excreted in mice through metabolic studies. Metabolic studies have shown that the vast majority of fluorescent whitening agents are rapidly excreted through the intestine and are not absorbed by the intestine after heavy feeding of CBS. There is no residual fluorescent whitening agent in their blood, liver, and muscle. Therefore, even if a small amount of fluorescent whitening agent CBS enters the body, it will be excreted quickly through normal metabolism.

• Fluorescent brightener CBS is not carcinogenic: The European Union Detergent Association (A.I.S.E.) has shown that fluorescent brightener CBS (also called FWA-5) is not carcinogenic.

The toxicity of fluorescent brighteners is of the same level as that of salt used daily, and the lethal amount of both is very close, which means that, like salt, it is only life-threatening to ingest more than 50g at a time.

Moreover, fluorescent whitening agents are widely present in the items we use every day. For example: most white plastic products, white candles, white tablecloths, plastic storage boxes and A4 paper.

In the nail polish industry, fluorescent brighteners are also commonly used in top coats. And the top coat is often used on color gel and hardener that have already cured and are unlikely to be absorbed, unless you eat it.

3: What is the role of fluorescent agent in the top coat?

Why is fluorescent agent added inside the top coat? First of all, the top coat is mixed by a variety of raw materials, they can't be all transparent and colorless, so the top coat will generally become yellow under the sun.

The blue-violet fluorescence emitted by a small amount of fluorescent agent can neutralize the yellow light emitted by the top coat itself and achieve a balance, so that the top coat will not turn yellow.

However, when a top coat containing fluorescents is applied to the surface of a dark color or black nail polish, it will turn blue under the sunlight. For this problem, we recommend using a crystal clear top coat that does not contain fluorescent brighteners.

As you can see in the picture, the top part of the nail is painted with a crystal clear top coat, and under UV light, the white color turns yellow and the black color remains unchanged. And the top coat with fluorescent whitening agent has no change in the white color under the UV light, and the black color will turn blue.

Therefore, the summary is that fluorescent whitening agent is not a dangerous ingredient, it is important to choose the top coat with or without fluorescent whitening agent according to the color you apply to your nails.

What is reinforced gel polish？

Reinforced gel polish, also known as hardener ,as the name implies, is a kind of UV gel that increases the firmness. But this is just a simple literal understanding, hardener's function and use can be more than you think. 

Reinforced gel polish has the role of preventing nail polish from warping and cracking, protecting the top coat and color gel from scratches ; Reinforced gel polish is a nail polish that is needed when doing manicure, because some people's nails are too thin, applying Reinforced gel polish can increase the thickness and hardness of the nail

A lot of girls like to do a beautiful manicure, but some girls nails are naturally thin and very soft, their manicure is easy to fall off or break very easy, and that's when the Reinforced gel polish will come in handy, reinforced gel polish as the name implies is used to strengthen the nail, it can increase the thickness and hardness of the nail, to avoid the nail too soft and nail polish gel warping, so even if your nails are thin and soft, with the reinforced gel polish used you will not be afraid of the nails breaking.

It is important to note that you don't need to wash the reinforced gel polish after you apply it, so you can put the color gel on directly after it is dried.

The reinforced gel polish can be the all-purpose gel in nail polish. 

Different formulas of reinforcing gel will have different effects, some reinforced gel polish will be a little thinner, some will be a little thicker.

For the less viscous reinforced gel polish, its functions are: 

1. leveling the nail surface

2. lighten the pen marks 

3. make the pattern more transparent and vibrant. 

4. For marble ink effect,  Due to its low consistency, the color gel will spread easily on the uncured reinforced gel polish. This way you get the marble ink effect.

For the higher viscosity of the reinforced gel polish,its functions are: 

1. strengthen the nail

2. to stick some small decorations 

3. to fill in the nail surface.

If your nails are thin, you can choose a thicker reinforcing gel so that your nails are strong enough.

The right steps are: 

first apply a base coat, then apply the reinforced gel polish on top of the base coat, and finally apply the color gel.

After applying the color gel, you can apply another layer of reinforced gel polish, which should not be cured, so you can fix some small decorations on the undried reinforced gel polish.

After adding some small decorations, the nail surface will be uneven, so you can choose to use a thinner reinforced gel polish to make the whole surface smoother. A less thick reinforced gel polish will have a good flow, so it will also lighten the brush marks left on the nail surface during the application of the color gel.

You can use a sanding strip to smooth the surface of the nail and apply the top coat at the end and done!

Reinforced gel polish is just another way of saying hardener, and we have a detailed article on unna hardener. 

Scrub nail polish is a special substance that is applied to nails after all manicure sessions. This special substance is called frosted bright oil, and the main components are generally oily solvents such as pearl powder, volatile solvents, and nitrocellulose.

How to wash Scrub nail polish dirty?

If the Scrub nail polish is dirty, you can wipe it with a glue remover. Pour a small amount of the debonder onto a cotton pad and wipe the nail surface gently and quickly. Remember that the glue remover should not be used too much, because it may wash off the nail polish and destroy the nail art.

You can re-apply a layer of frosted bright oil on the manicure, apply another layer of frosted seal on the nail polish glue, and dry it with a lamp.

After the surface of the scrub nails is dirty, you can re-apply a layer of scrub seal or scrub polish, and finally illuminate. You can also clean the dirt on the nail surface.

The matte texture of frosted manicures is loved by many girls. It has a high-level sense and looks very fashionable. If the surface of the scrub nail is dirty, you can wipe the surface of the nail with a wet towel to wipe off the dirt.

Since the surface of the Scrub nail polish is not smooth, it is easy to get dirty and not easy to clean. The surface of the nails has a rough feeling. After finishing, pay attention to daily cleaning and do not do rough work. Before choosing to do Scrub nail polish, you should consider the nature of your work. If the working environment is usually dirty, it is not recommended to do Scrub nail polish.

What is HEMA?

Today, we want to bring the truth to the nail industry and to all of the Manicure Lovers.

To be precise, what we are going to talk about today is "HEMA Free gel polish"

HEMA is one of those words that if you have heard Hema before, It’s kind of those crazy words that’s taken the industry by storm and people will have a huge reaction to it. And a lot of us don’t even know why we have a huge reaction.

Now let’s talk about what Hema is and why Hema could potentially cause problems

Hema, it’s chemical name is 2-Hydroxyethyl methacrylate

• So is Hema a necessary component in gels?

Actually Hema is added because it gives us really good adhesion of the natural nail.

Natural nails are made of keratin and keratin protein likes that are carboxylic acids and Hema is sort of a long-chain carboxylic acid with a hydroxyl group on one end.

The OH group on the Hema allows it to be more miscible with water so if you have water on you fingernails, so it doesn’t reject the Hema. Hema is also really good as its seen it only has one functional reactive site for the UV cured systems or acrylic systems. So because it only has one of those carbon-carbon double bonds on one end that’s the methacrylate, because it only has one of those it only can enter into one portion of a die functional reaction. So it becomes a chain terminator. If chains could get too long they can become too rigid or they can become too brittle or just not good adhesion.

So, Hema isn’t inherently a bad thing because it creates great adhesion to the natural nail plate, it could bonds with that. But one of the downsides of Hema is that it can get out of control if it’s not bound within the formula properly, or if you get it on your skin, and when you are applying things that contain monomeric Hema you want to make sure that you avoid skin contact. And that’s why as you may have see on pretty much every label for nail care products says “avoid skin contact”

• But there are ways that we can make formulas even safer than having Hema added. 

And so if you see Hema on the ingredient list that’s not necessarily a bad thing, but question might come up what’s the concentration of Hema in a systerm. If the product has 40 percent concentration of Hema in a gel polish system, that increases the chance of becoming allergic to the Hema. There is other molecules that we can use that also have good reactions and good adhesion in a natural nail.Take Hema’s sibling HPMA Hydroxypropyl methacrylate has one additional carbon atom in the backbone and that Hydroxypropyl methacrylate is less allergenic. So some products wind up taking something that has 50％ Hema to 25％Hema and 25％HPMA. And there’s other monomers can be added in there as well.

What’s the best solution?

The answer is “oligomers”. So how it compares to a monomer? 

Oligomer is typically molecule has been built based on the backbone of one of the resins so it’s basically Hema but attached to the Oligomer chain.  And oligomer is ten times the size of Hema monomer. As a result, It’s less likely to enter you bloodstream if it comes in contact with your skin, which makes it safer.

So why companies choose to put so much monomer instead of choosing to put more oligomers in their product?

The answer is very simple. Because Hema is very cheap, so with more Hema, the price will be cheaper. Because it reduces the raw material cost. Oligomers on the other hand are mega expensive. Compared to Hema the oligomers are about 10 times the cost.

As for unna, our brand was born with the goal of being 100% HEMA-free, and we tested the most common gel polishes on the market that claim to be HEMA-free. The result is that almost none of them can do so. 

We are willing to accept the test from the market and we are confident that we will become the new standard in the nail industry. We are looking for partners and agents all over the world. If you want to start your own business, please contact us and we will help you get started.
