How long do Simple products last? Does taking the “baddies” out mean products are less effective? Like other facial care products, unopened Simple products last for an average of 900 days.
What happens if you use expired face moisturizer? Expired products may not only lack potency, but could also cause an adverse skin reaction. If you’re unsure how old something is, the general rule is to toss anything that has significantly changed in color or odor, or separated, clumped, thickened or thinned, says cosmetic chemist Mort Westman.
How do you know if a product is expired? Products will contain an unopened or shelf-life expiration date on the packaging. This date tells us when a product expires even if it remains unopened and unused. Manufacturers typically print the second expiration date on the product.
Do skin care products expire if not opened? 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).
