How to distinguish the quality of nail polish? Why are there bubbles when applying nail polish?

Applying base coat before applying nail polish is to protect the nails, because nail polish contains some ingredients that are not good for nails, so base coat is usually applied first. So how do you distinguish good nail polish from bad?

1. Check the shelf life. High-end nail polish generally has a longer shelf life, and for the sake of convenience, it is better to choose one with a longer shelf life.

2. Check the application effect. Good nail polish is easy to apply, and the color is even without clumping.

3. Check the condition after drying. When trying it out, wait for the nail polish to dry and see if it will slowly fall off. If it does, don't choose it.

4. Check whether the color is stratified. If the nail polish is found to be stratified, it means that it has been stored for a long time and such nail polish should not be purchased.

5. Check the quality of the brush head. The brush head is the key point when buying nail polish. You should choose a longer and softer brush head for easier coloring.

1. If there are small bubbles on the painted nails, it may be because the surface of the nails is not cleaned properly and there is residual oil or moisture. The nail polish will not be easy to color where these impurities exist.

2. It may be a quality problem of the nail polish itself, or it may have exceeded its shelf life.

3. If the base coat and nail polish are not from the same brand, there may be a problem of low bonding, which may lead to the appearance of bubbles.

1. Nails must be cleaned thoroughly. After cleaning, avoid getting water or dust on your nails, otherwise the effect of the nail polish will be greatly reduced.

2. Choose nail polish of good quality, and try to choose the same brand as the base paint to avoid the problem of failure to adhere.

3. Apply nail polish in one go and try to avoid applying it back and forth to avoid bubbles.

4. When brushing, make sure the brush head is flat so that bubbles are not easily generated.

1. It will cause damage to the nails. Applying nail polish too frequently will cause the nails to become thinner and cracked.

2. It will cause physical discomfort and may cause various diseases such as contact dermatitis, allergic rhinitis, etc. Some nail polishes may also produce carcinogens due to irregular production.
