Expired Beauty Products
Hanging on to beauty products past their prime won't do your skin any favors. Aside from the safety aspect, if your skincare product contains antioxidants or skin-replenishing ingredients, they will eventually start to deteriorate and get contaminated. That's why it's important to note the PAO (period after opening) and BBE (best before expiration) symbol on your beauty products. A PAO and BBE indicate how many months after opening a product, you should throw it out. Another way to tell if your beauty product has gone bad is to see if it has changed color, separated, developed a strange odor, or feels different on your skin.
