First of all, you should select products with quality assurance, do not buy cosmetics without manufacturers and commodity labels, and also pay attention to the presence of inspection certificates and production licenses to prevent counterfeiting. Also pay attention to the production date and expiration date of the cosmetics.

Secondly, when choosing cosmetics, we should take into account the individual differences of the user and the environmental factors. For people of different ages and genders, we should consider using different skin care products; children have young skin and less sebum secretion, so they need cosmetics for children; elderly people have shrunken skin and dry and thin skin, so they should use cosmetics containing oil, moisturizing factors and vitamin E; men have strong sebum secretion and thicker stratum corneum, so they should use cosmetics for men that contain less oil.

For the first time use of cosmetics, should first apply a small part of sassafras in the ear or hand to do a simple skin test to determine no allergic reaction before starting to use. In the use of cosmetics should follow the principle of using as little as possible, do not abuse. People who have a history of skin allergies should be especially careful, and if they find that cosmetics have adverse reactions to their skin, they should stop using them immediately.

Finally, cosmetics should be properly stored in a cool, dry place to avoid the effects of high temperatures and high humidity on them. For cosmetics that have been opened should be used up as soon as possible, and it is best to avoid taking them directly by hand when using them, instead using clean cotton swabs and other tools. If you take too much at a time, you can apply it to other parts of your body and not put it back into the bottle. Makeup tools used on a regular basis should also be properly stored to reduce contact with dust in the air and to develop the habit of cleaning them regularly.

We all have a love of beauty, and there are more and more types of cosmetics on the market. We hope that when we buy and use cosmetics, we will remember the points we just mentioned and use them reasonably and correctly, so that we can become more beautiful and make our lives more beautiful.
