How long will the skin care product be unusable?

I believe many people know that skin care products must be used within the shelf life, otherwise it is easy to cause damage to the skin. But you know what? Usually, the shelf life of skin care products we use refers to the shelf life of skin care products that have not been opened for storage. After opening, the shelf life of skin care products is basically not that long. So how long will the skin care products be unused? Let's have a look.

How long can the skin care products not be opened with after one year of the skin care products have not been used up, it is better not to use them. Generally speaking, the shelf life of skin care products is 3-4 years, but here the shelf life refers to the shelf life of unopened. Once skin care products are opened, there will be a shelf life in Kaifeng. The shelf life of skin care products in Kaifeng ranges from 3 months to 12 months. Most of them need to be used in half a year or one year.

Most skin care products will have an open bottle cap sign at the bottom of the bottle body, which contains "12M" or "6M". M is the abbreviation of Month in English, indicating the month. This sign means that cosmetics can be stored for 12 months or 6 months after they are opened. If there is no open label on the bottle body of skin care products, we should also pay attention to the fact that most of the use dates of skin care products are usually one year after the opening.
