1. It has an appropriate drying speed and can be hardened.

2. It has an viscosity that is easy to apply to nails.

Nail polish is a nail art tool, and different styles of nail polish can also meet the different nail needs of MM, so it is particularly important to choose a nail polish with the best quality. So do you know how nail polish can tell the difference between good and bad?

How to distinguish good nail polish from bad

1. Look at the expiration date. Premium nail polish generally has a longer shelf life, and for the sake of convenience, it is better to choose a longer shelf life.

2. Look at the effect of smearing. Good nail polish is easy to color, and the color is even, so it doesn't clump up.

3. Look at the condition after drying. When trying on, wait for the nail polish to dry, and see if it will slowly fall off the slag, and if it does, it will pass.

4. See if the color is layered. If you find that the nail polish has a layered condition, it means that it has been stored for a long time, and such nail polish cannot be bought.

5. Look at the quality of the brush head. Brush heads are the focus of nail polish shopping, and you should choose a longer, softer brush head for better color.

What to do if your nail polish is dry

1. Add nail polish thinner. This is the safest method, a special nail polish thinner can target any color and texture of nail polish, add a few drops of thinner to the dry nail polish, and the magic effect will be immediately visible!

2. Add water. Add water to dilute the nails that are specifically designed for natural water-based nail polishes, which dry out by simply adding a few drops of water and shaking well.

3. Add transparent nail polish. In addition to the above methods, the dried nail polish can also be diluted by adding ordinary transparent nail polish, of course, you have to pay attention to the dosage, otherwise if you add too much, the original nail polish will be diluted.

1.Observe the shape of the brush

Observing the brush can tell whether the nail polish is good or bad. The method is very simple, you only need to take out the brush covered with nail polish, at this time, if the brush is still slender at the end, it means that the brush is good. However, if the brush becomes thicker, it means that the quality of the brush is not good, and if even the quality of the brush is not good, it is conceivable that the nail polish is not much better.

Therefore, looking at the brush is a very simple and effective way to distinguish the quality of nail polish.

2.Check the brush elasticity

The elasticity of the brush is also very important, and generally the better the elasticity, the better the quality of the brush, and the higher the quality of the nail polish. When inspecting, take out the brush, and then press the bottle mouth left and right, so that you can see whether the elasticity of the brush is qualified. If it is difficult to restore the original shape after the brush presses the bottle mouth, or it is relatively hard, it means that the quality is not good.

3.Observe nail polish

After all, the brush is only a part, to judge the quality of nail polish, we also have to pay special attention to the nail polish, you can take out the nail polish brush to see if the nail polish is smooth down the brush, and at the same time pay attention to see if it is droplet-shaped. Generally, nail polish of acceptable quality will be in the shape of water droplets when sliding down the brush. At the same time, pay attention to the speed of its dripping, if the flow is very slow, it means that the bottle of nail polish is too thick, and it is not easy to apply it well and evenly when applying.

4.Pay attention to check the production date

It is the same principle as when we buy food and daily necessities, and it is important to look at the production date, which can not only help you choose high-quality nail polish, but also better ensure human health. Nail polish must be used within an effective time, otherwise it will easily volatilize and dry out, and both the color effect and uniformity will be greatly reduced.

To identify the worst nail polish, it is necessary to see whether the hail has the following properties:

1. It has an appropriate drying speed and can be hardened;

2. It has the viscosity of good sails that are easy to coat nails;

3. The place where it is applied can form a uniform coating film;

4. The color can be uniform and consistent;

5. Good nail polish will dry quickly after application;

6. Press the brush left and right on the bottle mouth, try the elasticity of the brush, and choose the slender nail polish of the brush, which is easy to even.

Nail polish:

Nail polish: also known as "nail paint" and "nail polish". Its main components are 70%-80% volatile solvent, about 15% nitrocellulose, a small amount of oily solvent, camphor and oil-soluble pigments.

After nail polish is applied to the nails, the solvent contained in the nail polish volatilizes to form a colored film, which then adheres to the nails with a moderately colored luster, which can protect the nails and give the nails a sense of beauty. It is a kind of nail polish that does not need to be lit, and is also known as self-drying nail polish, so nail polish is generally placed in a transparent bottle, and it needs to be sealed when it is stored.

But, you know what? This convenient and fast self-drying nail polish is not an ideal nail art material, in order to make the nail polish dry easily, the solvents used are mainly acetone, ethyl acetate, phthalate, formaldehyde, etc. When these solvents are volatilized, they will be inhaled into the human body, which will make the human body feel uncomfortable, and if they are inhaled for a long time, it will also affect the health of the human body; In addition, due to the strong permeability of nail polish, it may cause some bad consequences for children with fragile nails, for example, children who use nail polish too often to make nails, the nails may be yellow, dull, and in severe cases, paronychia may also appear so that nail polish must be careful not to get on the ** Oh accidentally sticked, wipe it clean with nail polish remover before drying.

Nail polish glue:

Nail polish glue: on the market, it has become QQ glue, Barbie glue, phototherapy glue, etc., its main components are natural resin and some color materials, this material will be cured under ultraviolet light, not volatilized, it will form a plastic-like film Permeability is worse than nail polish, but gloss, wear resistance and firmness are better than nail polish, the most important thing is that it almost does not volatile gases, will not have much taste, and the drying time only takes one or two minutes, not like nail polish in general, It may take about ten minutes for it to dry. So now there is a situation where nail polish glue is gradually replacing the position of nail polish

Because nail polish glue has the characteristics of curing in the light, nail polish glue is generally sealed in a opaque bottle, and it needs to be stored in the dark when preserved, and the advantage is that as long as the ultraviolet light is not too strong, the nail polish glue will not solidify so quickly, which is convenient for drawing patterns and modifications

Finally, let's talk about the difference between nail polish and nail polish glue The operation of nail polish is generally: base coat - color paint - bright oil; The nail polish glue is: primer - color glue - sealing layer, each layer should be dried with a light therapy lamp when doing It seems that nail polish glue is more troublesome, but from the health and practical aspects, the cost performance of nail polish glue is far higher than nail polish!

Okay, that's all for today's small class If you have other questions, reply to your questions, and our nail technician Aimi will come to reply to everyone's questions

First of all, nail polish that smells too strong is definitely not good. MM can brush on the foam before buying nail polish, if even the foam board is corroded, the nails can be imagined

Also, you can see if there are any lumps in the nail polish. Generally, there will be impurities when the oil is not very good, and there will be color delamination if it is left for a long time, as if it is separated (a bit like the delamination phenomenon seen in chemistry class). However, in order to be even out and prevent drying, some nail polishes will add two small steel balls to it, which is normal

En, in addition, if there is a trial size, see if his brush head is soft and neat, such a brush head will be much more convenient when we brush

After buying it, see if it's easy to drop it after brushing. It's a complete lie to say that water-based eco-friendly nail polish is easy to fall off!! Good nail polish must have stamina! The Chanel I bought last time I gritted my teeth and stamped my feet was really there!

To put it simply, it's just 2 points.

First of all, the taste, the natural quality of the heavy taste is a little worse, of course, the cheap and good brand nail polish will not have such a heavy smell, and even without nail polish, the high quality will be very delicate after application, whether it is a nail art or some popular monochrome figures, it is very even and plump.

Therefore, it is recommended to choose brand counter goods that are acceptable in terms of cost performance.

I don't think the taste is very strong. It's good that the color is very uniform. Personal opinion. Non-professional.

Apply nail polish to the foam, bad nail polish will be terrible, good nail polish will be fine.

Taste and color are all differences in appearance, but the most fundamental thing is to see whether the ingredients of nail polish have harmful substances, and the one with a test report is the best, regardless of whether the brand is true or fake, but there is no test report for the fake one.
