What is the purpose of the unused red nail polish?

You can decorate bottles and jars, graffiti on the walls, etc.

If possible, the landlord may wish to go to the nail salon for care.

If you say your own, buy a polishing block, polish it, buy a bottle of better primer, and buy a bottle of bright oil, first apply primer, then nail polish according to personal preference, and finally apply bright oil.

The base oil bright oil is recommended OPI's set Both bottles are included in it, and it is best to buy it online, which will be much cheaper.

Nail polish is still recommended opi If you find it troublesome or too expensive to buy, it's not bad to buy Revlon or something.

Nail polish is applied underneath, then nail polish is applied, and a thin layer of clear nail polish is added at the end. This way it won't fade so easily.

Also note:

1.Be sure to wait for the nail polish to dry before applying other nail polish2Try to apply each layer too thickly to make the color even.

3.Nail polish is harmful to the body, so it's OK to use it occasionally. Just like a person's **, applying too much will also hinder its breathing.

First of all, you should choose the best nail polish, which is not only easy to last, but also healthier for the body.

Second, before applying nail polish, do a good job of cleaning and treating the nail surface, wash off the residual nail polish and trim and polish it with a nail file, a smooth nail surface is more conducive to the retention of nail polish.

Third, apply nail polish layer by layer in the order of base coat - nail polish - bright oil, and the latter layer should be dried to 8 percent or completely dry before applying.

The base coat wow, and the base coat should be chosen well, because it is the "barrier cream" of the nails.

Yellowish hands, especially those in the winter months, tend to be darker, so using nail polish to brighten the entire skin tone is the most important thing. People with yellow hands in winter can choose nude, champagne, light orange, peach, shrimp, and brown-gray nail polish (be careful not to use bright orange), which can visually brighten the color of the skin on the hands.

Personally, I think it can be unified with the bright spot color of your upper body, that is, if you plan to use a certain eye-catching color accessory to embellish, the nail polish color can be the same as it; If you plan to wear clothes in a certain color, then your nail polish color is the same as this color system.

Of course, it can be used, and there is no harm in drying it out.

Nail polish is also known as "nail paint". Its main components are 70%-80% volatile solvents, about 15% nitrocellulose, a small amount of oily solvents, camphor, titanium dioxide and oil-soluble pigments. The thin film formed by nail polish applied to the nails is firm and has a moderately pigmented luster, which not only protects the nails, but also gives the nails a sense of beauty.

However, most of these raw materials have certain biological toxicity, and should be avoided from entering the human body, causing chronic poisoning. After applying nail polish, do not hold the food with your hands, so as not to stick the nail polish to the food, and prevent "poison from entering the mouth". In particular, it should be noted that oily fritters, cakes and other oily foods should not be eaten with your hands, because the compounds contained in nail polish are fat-soluble compounds that are easy to dissolve in oil, so you should be extra careful.

At the same time, nail polish contains a substance called phthalate, which is not only very harmful to human health if it is absorbed by the human body for a long time, but also most likely to cause miscarriage and give birth to deformed babies in pregnant women.

I myself love to wear nail polish, especially the transparent type. It's a good match, and it's not too conspicuous. But sometimes I think that when my nails touch food, such as bread, there are strips, I worry, no matter what, eh.

So in the end, I didn't get into this habit. Changing nail polish often can also damage nails, and painstaking care and maintenance does not seem to be very wise.

That's my opinion. It's your own judgment that matters.
