What is a cosmetic product’s shelf life? A product’s “shelf life” generally means the length of time you can expect a product to look and act as expected and to stay safe for use. This length of time varies, depending on the type of product, how it is used, and how it is stored.
What is the shelf life of skin care products?
Specific products can vary, but in general, unopened skin care can last from one to three years. After opened, you should use a product as directed promptly, within one year. Always throw away a product if it seems discolored, develops a strange odor, or the consistency changes (if it becomes lumpy, runny, etc).
