Does Sunscreen Expire?
Yes, sunscreen expires and should be replaced after the printed expiration date, typically 2-3 years from manufacture. Expired sunscreen may not provide the stated SPF protection, putting you at risk for sunburn and skin damage. If there is no date, discard sunscreen after 3 years.
Key Takeaways
- Sunscreen ingredients break down over time, reducing their ability to block UV rays.
- Mineral sunscreens (zinc oxide, titanium dioxide) may remain stable slightly longer than chemical sunscreens.
- Spray sunscreens have the same expiration considerations as lotions.
Explanation
Sunscreen ingredients break down over time, reducing their ability to block UV rays. The FDA requires sunscreens to maintain their original SPF strength for 3 years. After expiration, you may be getting significantly less protection than the label indicates.
Signs of degraded sunscreen include changes in color, consistency, or smell. Separation, graininess, or a watery texture suggest the formula has broken down. However, sunscreen can lose effectiveness even without visible changes, so follow the date.
Proper storage extends sunscreen life. Keep it in a cool, dry place away from direct sunlight. Do not leave sunscreen in hot cars or beach bags in the sun. Heat accelerates ingredient breakdown significantly.
Things to Know
- Mineral sunscreens (zinc oxide, titanium dioxide) may remain stable slightly longer than chemical sunscreens.
- Spray sunscreens have the same expiration considerations as lotions.
- Sunscreen in extreme temperatures (frozen or very hot) may degrade even before expiration.
