Does Sunscreen Expire?

Q: Does sunscreen expire? Is sunscreen still good from last year?

A: According to Mayo Clinic, sunscreen does expire after 3 years. Sunscreens are designed to hold its strength for up to three years. This means you can use the sunscreen you bought last year. For older sunscreens, check the date and if you aren't sure just toss it. And, always remember to reapply!
