Can you use sunscreen after its expiration date?

The U.S. FDA says not to use sunscreen after the expiration date printed on the package. If there is no expiration date, FDA says to treat it as expired three years after purchase.

Why the date matters

Sunscreen is intended to provide the protection stated on its label when used as directed. After its expiration date, it may no longer be safe or effective. Do not rely on an expired product to protect you from sun exposure.

If a sunscreen has no printed date, use your purchase date to track the three-year limit described by FDA. If you do not know how old it is, discard it. Store sunscreen as directed on its label, since heat and poor storage can affect products.

Check the product and label

Look for the expiration date on the container or box. Follow the product's application and reapplication instructions, and use other sun-protection measures when needed. An SPF number does not tell you how long you can stay in the sun without burning.
