How to identify the safety of cosmetics

Nowadays, cosmetics have become daily necessities in our lives. However, in recent years, cosmetic safety incidents have occurred frequently. Therefore, people are paying more and more attention to the safety of cosmetics. At present, the types of cosmetics on the market have increased, with various and complex ingredients. How to judge the safety of cosmetics?

At present, in addition to using professional testing instruments to identify the safety of cosmetics, we can also master many tips to identify the pros and cons of cosmetics, which are mainly reflected in the following aspects:

First, look at the QS logo and three certificates (production license, health license and execution standards). If there is a QS logo and three certificates on the packaging, it indicates that the cosmetics are produced by a regular manufacturer with production qualifications, so you can be relatively assured.

Second, look at the ingredients. When choosing safe cosmetics, the first thing that comes to mind is to look at the ingredients. Cosmetic labeling management stipulates that all produced cosmetics must label all ingredients contained on the outer packaging or instructions.

Third, use your nose to smell and feel the smell of skin care products. You can distinguish whether it is a natural smell or a chemical fragrance. Cosmetics that do not add chemical fragrances will make people feel soothing and stress-relieving. In order to cover up the unpleasant smell of certain chemical ingredients, some cosmetics will choose to add chemical fragrances. Using cosmetics containing a large amount of chemical fragrances will cause skin allergies, dermatitis or pigmentation, etc., thus making the skin worse and worse. .

Fourth, silver jewelry detection method. Some cosmetics with whitening and freckle removal effects generally contain vitamin C and arbutin. Their main feature is that they can slowly improve skin quality. Those so-called cosmetics that can quickly and efficiently whiten and remove freckles contain a large amount of harmful substances such as lead and mercury. Chemical substances, such as cosmetics containing lead and mercury that consumers use for a long time, can cause chronic poisoning of the body. Therefore, before using this type of cosmetics, be sure to dip a small amount of skin care products into silver jewelry and make a few scratches on white paper. If the marks on the white paper turn gray and black, it means that the cosmetics contain a large amount of lead and mercury and are strictly prohibited from use.

Fifth, pH test paper test method. Since human skin is weakly acidic, only weakly acidic cosmetics can achieve skin care effects. Before use, you should apply a small amount of cosmetics to the pH test paper. After comparing the color chart of the test paper, if the cosmetics are alkaline, avoid using them.
