Q&A: Do sunscreens expire?

Should I throw away the tubes of sunscreen that have been sitting in my medicine cabinet for several years? —J.A.,Torrance, Calif. 

Most likely. Sunscreens eventually start losing their sun-protecting power when the ingredients start to separate.That generally happens after the expiration date, which should be printed on the label; it’s usually two to three years after the product was made.Toss out any sunscreen that has expired or shows signs of separating, such as grittiness or changed appearance.
