Many women and men may not know that cosmetics also have an expiration date, just like other products. Many people may not be interested or give much importance to checking the manufacturing date or expiration date. But of course, expired cosmetics are something that should not be used. Even though some people may argue in their minds that the cosmetics they are using have been used for many years, they do not see any danger in it.
But because expired cosmetics are a source of many contaminants and bacteria that damage the skin. When the product expires, of course, the condition of the product will change. Now, microorganisms, contaminants and bacteria will grow rapidly. So we should not use it anymore. Even if it still looks good, it seems like it can still be used. But we have to throw it away for the safety of our skin health.
