What is the shelf life of facial cleanser?

Most facial cleansers have a shelf life of three years if they are unopened, but if the facial cleansers have been opened, then their shelf life is only one or one and a half years. It is best to use up the facial cleanser within 3 to 6 months after opening. If you still have not finished a bottle of facial cleanser after six months, it is recommended that you do not use it again. Although it has not expired, once it is opened, bacteria will enter it and cause the facial cleanser to deteriorate. Many people think that facial cleanser is just something used to clean the skin, so its shelf life should be longer than that of cosmetics. But in fact, the shelf life of facial cleanser is not longer than that of cosmetics, and may even be shorter than that of ordinary cosmetics. Although the manufacturer has marked its shelf life, the shelf life marked by the manufacturer is the shelf life when the product is not used or opened. Once opened, their shelf life will be shortened by half or even two-thirds.

What are the benefits of amino acid cleanser for sensitive skin

The nature of amino acid and other facial cleansers is very gentle and has a certain maintenance effect on the sebaceous glands. After using them on sensitive skin, they can help repair the skin, enhance the skin's resistance, and avoid symptoms such as redness, itching, and dryness due to washing the face.
