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.
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.
Do you often get a lot of questions about the lamps used in manicure? After all we have talked about the gel application, we should also be clarified with the lamps. Because if you don’t have curing down it doesn’t matter how awesome your application and your nail are, it’s all going to come off. And we definitely don’t want that for ourselves or our clients.
The first question is: What's the difference?
Here is a picture of a traditional UV lamp. It’s probably the most common that you’ll see especially if you’re just starting out or if you’re looking for a cheap type of lamp. This is the very original one. What a traditional UV lamp really is, is a CFL UV lamp CFL means compact fluorescent. And there is also CCFL which means cool cathode or cool compact. And the fluorescent bulbs in it are what makes it work. This fluorescent light bulb emits a portion of the spectrum of UV light. So with this, you can cure the gels. This lamp was usually used about ten years ago.
But now days, LED has completely taken over. It has a different type of light bulb inside. And LED stands for light emitting diode. You may find some of the LED bulbs have different colors, some are yellow some are transparent. That’s because they have different style of dome over the bulb to spread the light and also to protect the bulbs.
And what important is this is also UV lamp. So you can see the difference, CFL lamps and LED lamps are both UV lamps but with different bulbs. And they both cure gel polish.
So why are CFL lamps are replaced by LED lamps?
LED UV lamps are able to emit the full spectrum of light needed to cure both traditional gels and the newer LED formulas and so they can cure all the gels. So you don’t need to replace the bulbs to cure specific gels. And you can expect it to last five years or more and it almost never lose power.
You don’t need to replace the bulbs in LED lamps.
The bulbs in CFL lamps usually need to be changed after six months, because they lose their ability to cure. And LED lamps don’t have that problem.
3. LED lamps take less time to cure the gels.
How do we choose the right UV nail lamp:
In the past CFL lamps could take up to five minutes to cure traditional gels. But LED lamps with that focus very high penetrating type of light that’s going into the gel, they only need up to 1 minute to cure the gels. So LED lamps not only do faster but also better job.
But because LED lamps doesn’t glow as much as CFL lamps. It’s very focused. So you have to ensure that the number of LED bulbs to be more but also arranged properly, even on the sides.
what wattage led lamp do i need for gel nails?
About 36 watts.
the wattage of lamps is divided into 9 watts, 18 watts, 36 watts, 42 watts, the higher the wattage nail hardening speed is faster, but you need to check the relevant information before using.
The light of the nail lamp belongs to the long-wave ultraviolet light, generally does not produce serious damage to the skin, but it does make the skin tanned, aging.
Although it is harmless to take a short time to cure, you should always pay attention to the maintenance of your hands. It is best to apply sunscreen and then do your manicure
Regular nail polish: been used for a hundred years. Easy, and affordable.
Gel polish: been used for around 40 years and with some amazing features. Yet it is little high maintenance.
Regular nail polish:
For starters cost and supplies are very different, for regular nail polish, you don’t really need that much. You need a cuticle stick to push your cuticles back. You need a good file to be able to buff the natural nail and then another file to smooth it. Then you need a little bit of oil to get rid of the dust. Then you can wash your hands. Then you need a base coat, coat of color and a top coat. Finally you are gonna need some time to let it dry.
And as for gel polish,
It’s basically the same. But you need a compatible lamp that go with the gel polish.
Both polishes begin with pushing back the cuticle. Both applications also require some filing to prep. And oil goes on before nail polish application. But gel polish need more complicated preparation on nails. And that is what makes it last. And after applying the base coat, here comes the biggest advantages for gel polish, the lamp. While regular nail polish are applied, you must to wait for it to dry. It may take 3 to 5 minutes or even more. But for gel polish, when you put your hand in the lamp ,you know between 30 to 60 seconds, It’s completely cured. And that's how you can recover the time you lost in the preparation phase.
And another cool thing about gel is it doesn’t dry as you apply and it also self levels. These are some amazing features that rugular nail polish doesn't have. And It’s going to last at least two weeks on natural nails
But when it comes to remove the nail polish gel polish could get little more tricky. And for regular nail polish, you just need to get yourself some nail polish remover and take some time to wipe it off.
To remove gel polish, you need to first use a nail drill machine to sand it, then continue sanding it with a file, and finally wrap your nail with a nail remover pack. This can take up to 15 minutes or more. But to protect you natural nails, you have no choice.
So here is the conclusion.
It isn’t a matter of either or it’s just a matter of what service and what type of nail and durability and cost and time of service you are looking for.

The base coat of colored Nail polishes must usually be colorless, i.e. transparent, so that the colored Nail polish on the back can bring out the color better. There are also some base oils with some color, such as light pink and light blue. In fact, this type of Nail polish is almost invisible when applied to the nails, but it is also possible, but do not use the type of Nail polish that is visible when applied, as this will affect the color saturation of the later applied Nail polish.
What should I pay attention to before applying colored Nail polish?

Why Gel Nail Polish is better than Regular Nail Polish？
Regular nail polish is always tried and true.
This is a necessity for middle school students to spend the night away, and a staple for the working woman’s outfit planning.
But what about gel nails? What can gel manicure give you that regular nail polish can't give you?
Gel manicure has still quickly become the main product of salons.
Nevertheless, for those who are not sure whether to try new gel polishes, we have collected their benefits for you:
Gel nail polish is thicker than regular nail polish.
The main feature that distinguishes it from classic manicure is part of the curing application process
because gel nail polish does not dry naturally.
Curing refers to putting the nails under LED or ultraviolet light to activate the chemical process to dry each layer of nail polish.
Considering that the gel nail application has extra time to repair the nail polish,
you can immediately leave your appointment or home application to completely dry the nail.
Quick-drying, durable formula, gel polish is hardly broken.
Your gel manicure is very resistant to peeling or stains, and the color will be as bright and shiny as the first day.
Gel polish can be used for at least 2-3 weeks, while regular nail polish will not fall off for a week.
In the case of light application, your gel nails last at least twice as long as normal nail polishes,
but in fact, they can make your nails four to six times the standard.
Take the core ingredient color powder as an example:
when creating nail art, it is sometimes necessary to apply each color layer very thinly,
with a thin multi-layer color overlay that brings an exceptionally soft visual beauty.
The thickness of each layer is so thin that it can only be counted in microns after the color layer dries,
which requires the particles of the color powder to be very finely ground. unna selects German color powder,
processed by ultra-fine grinding process into nano-level color paste, super fine and smooth.
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. Today we'll get to know what hardener really is.
First of all, when our nails become thin and soft for some reasons, you can apply a layer of hardener after the base coat. This way the overall hardness and toughness of the nail is improved. This prevents the nail from breaking frequently and we can easily retain the length of the nail as you wish.
Also, this layer of hardener fills in the little pits on the surface of the nail. The next time you apply a color gel, you can easily apply it evenly and more flatly.
Also, by applying the hardener in the middle of the color gel and the top coat, the color gel will be better protected and will stay on the nail longer.
In addition to the above uses, when you want to put small decorations on the nail surface, such as: irregular size sequins, shell pieces, laser paper, etc., you can use hardener to fix it. Compared to the thinner top coat or thicker builder gel, the consistency of hardener is moderate, easy to operate, fast and convenient.
After applying these decorations and sequins, there will be a lot of uneven areas on the surface of the nail, which cannot be completely filled with the top coat only. It's too sticky and slow to use builder gel. So a moderate viscosity reinforcement glue can cover the raised unevenness, but also easy and fast to apply, and if there is still unevenness, you can also sand it with a sanding strip.
When you need to use a certain transparent color and do not have it by your hand, you can find a similar solid color gel with hardener to adjust the transparency. Because the consistency of the hardener is similar to that of a normal color gel, it is very easy to mix it and apply it directly with a clean brush that has been cleaned up with top coat or base coat.
Finally, there is a hidden feature of the reinforcing gel, which is the color gel blooming function. We can apply a layer of hardener on the base color without curing it, and then use various techniques to make the color gel on the hardener gel surface gradually spread out, thus forming a variety of style. Very flexible and practical.
The above is an introduction to the common knowledge and use of hardener, Hope you will gain more in learning and practice.

Gel manicure are all the rage right now. Everybody loves gel nail polish, but you’re probably removing your gel nail polish the wrong way. So today we are going to learn the right way to do it. And you can do it yourself at home.
The first way to do it , you need to prepare the tools that you need to accomplish this task.
1: Cotton balls
3: Nail groomer
4: Aluminum foil
Step 1: take 1 cotton ball, this is going to remove all of your gel polish from both hands. You can break it up to tiny pieces and what you’re going to make sure you do is you divide them into 10 separate little pieces for each nail. The cotton don’t need to be very thick beacuse you need to dip them into your acetone.
Step 2: once it’s completely saturated, put the saturated cotton ball onto the top of your nail bed and you want to make sure that you are not wrapping your entire finger with the cotton ball. This will dry out your cuticles and your nails, which is not good.
Step 3: take a small piece of aluminum foil and wrap the nail. This will create a heat conducting type of mechanism and help acetone completely goes through the gel polish. After five minutes, you can check if the gel are peeling. If your gel nails has only been on your nails for about a week, you need to wait little more longer, about ten minutes.
Step 4: after five to ten minutes, take off the aluminum foil. If you see the gel polish actually peeling up off of your nail,them you are ready for the next step. Take your nail groomer or a wooden stick, and start to push off the gel polish very very gently. Starting at your cuticle and ending at your tip. If you do it backwards and start at the tip, you will risk severely damaging your nail, which completely contradicts the whole purpose of removing your gel polish correctly
Step 5：after you remove all of your gel polish, you want to take one more cotton ball, and dip it in some acetone. Then swipe over your nail lightly to get rid of any excess polish that is left over. And finally, you may find your cuticles are a little bit dry. All you need is a bit of cuticle oil and even a moisturizer. Then your nails are good to go.
Now you know the right way to remove your gel manicure without sanding down your polish or peeling it off.
And sometimes, if the acetone doesn’t work very well, you need to start your process with buffing the gel polish. The more you can take off with the file the less time you are going to spend on soaking.
Make sure you don’t buff your natural nail, because that will cause serious damage to your nails.
Regarding the tools, you can improvise. You don't necessarily have to use aluminum foil, plastic wrap can work just as well.
If you do not want to spend too much time on this. You may also choose not to use cotton balls. Take some Acetone in a cup and sand the surface of your gel polish slightly. You can then dip five fingers into the acetone. This is very unfriendly to your cuticle and the skin of your fingers, but you can remove the nail polish very easily.
We recommend that you stock up some nail removal packs around the house. It is very convenient. All you need to do is peel off the package, cover the surface of your nails with the cotton side, and stick it on your finger. 5 to 10 minutes later, you can easily remove your nail polish.
Prime your nails before applying nail polish. In addition to remove grease or cream around and at the base of your nails, apply a protective layer to your nails. Shake the nail polish before applying nail polish to make the color in the bottle as uniform as possible.
