First, the shelf life after opening
Food has a shelf life, but after opening, it will speed up food deterioration. Just like the milk we drink regularly, the shelf life is generally 6 months. If you open and drink half of it and put it in the refrigerator, you must finish it within 4 days after the prescribed opening period. In fact, skin care products are actually the same. This is because the substance in the skin care product is in contact with the air after opening, and is prone to oxidation and deterioration.
This mark is generally near the bar code and refers to the best use of skin care products or cosmetics after opening the package.
This is different from the unopened shelf life we generally see, which is generally displayed in the text message of the product package.
Second, the license mark
The license mark is an important basis for the identification of “three no products”.
There are only two categories in the management regulations for domestic cosmetics. The cosmetics used for dyeing perm, whitening, sunscreen, etc. are collectively referred to as special-purpose cosmetics, the batch number is “Wei makeup special”, and the common cosmetic batch number is “wei makeup”.
Most cosmetics sold in the market are mainly based on "wei makeup", but there is no "medicine".
Imported cosmetics must be marked with the Ministry of Health's "Wei makeup into the word" or "Wei makeup into the word" symbol.
The skin care products sold in the market need to be filed with the State Food and Drug Administration. Whether it is a three-nothing product can also be inquired on the official website of the State Food and Drug Administration.
Talk about our common "cosmetic":
At present, China does not have the approval number of “pharmaceutical makeup”.
There is no uniform definition of "pharmaceutical makeup" in the world. In Europe and the United States, "pharmaceutical makeup" refers to an active product having the characteristics of a drug or similar drug sold as a cosmetic product. In Japan and South Korea, functional cosmetics such as whitening, wrinkle removal, and sun protection are defined as medical skin care products.
Third, cosmetic packaging
In addition to the logo on the package, the package itself has something to watch out for.
Today's cosmetics and skin care products basically have a perfect anti-corrosion system, but the habits and packaging and storage conditions (such as the jars mentioned by the koala sister above) will have an impact on the hygiene of the products.
The most susceptible to secondary pollution is the jars and balls.
Jars, as the name suggests, are large bottles, such as the most common masks, creams, as well as air cushions, blush, powder and other large contact surfaces.
Ball-type eye creams, essences, antiperspirants and perfumes, after exposure to air and skin, bring the carried pollution to the product by rolling, causing bacteria to breed.
The cleanliness and safety of the package are relatively good, such as rolling nozzles and extrusions.
