Does sunscreen expire? Learn how to read expiration dates, how long SPF really lasts, and when to replace your COOLA favorites. Keep your sun protection effective.
Quick answer
Yes, sunscreen expires. The FDA requires sunscreens to retain their original strength for at least three years, but if there's no expiration date, assume it expires three years from purchase. Once expired, the SPF protection may be weaker, so it's best to replace it. Always check the date on your COOLA products and store them properly to maximize shelf life.
How to Read Sunscreen Expiration Dates
Sunscreen expiration dates are usually printed on the tube or bottle, either as a specific date (e.g., 'EXP 2026-12') or as a symbol like an open jar with a number and 'M' (e.g., '12M' means 12 months after opening). If you don't see a date, the product typically expires three years from the date of purchase. COOLA products include an expiration date on the packaging, so check there first.
How Long Does SPF Last?
Unopened sunscreen generally lasts three years from the manufacturing date, as required by the FDA. Once opened, its shelf life can be shorter—usually six months to one year—because exposure to air, heat, and bacteria can degrade the formula. For COOLA sunscreens, follow the period-after-opening (PAO) symbol on the label. If you can't find it, play it safe and replace after one year of regular use.
Is Expired Sunscreen Safe to Use?
Expired sunscreen won't necessarily harm your skin, but it may not protect you as well. The active ingredients can break down over time, reducing SPF effectiveness and increasing your risk of sunburn. If the texture, color, or smell has changed, toss it. When in doubt, replace it—especially if you'll be spending extended time outdoors.
Signs It's Time to Replace Your Sunscreen
Besides the expiration date, watch for these clues: the formula separates, becomes watery or gritty, changes color, or develops an odd odor. If the bottle has been exposed to high heat (like a hot car), replace it even if the date hasn't passed. For daily use, mark your calendar to replace your go-to sunscreen every six months to a year.
Sunscreen Storage Tips to Extend Shelf Life
Store sunscreen in a cool, dry place away from direct sun. Avoid leaving it in the car or by a window, as heat accelerates degradation. Keep the cap tightly closed to prevent contamination and drying out. If you're using a stick formula, like COOLA's Clear Sunscreen Stick, keep it out of extreme heat to maintain its texture.
Sunscreen Expiration FAQ
- Can I use sunscreen after its expiration date?
- It's not recommended. The SPF may be reduced, leaving you vulnerable to sunburn and skin damage. Replace it with a fresh product. When in doubt, throw it out.
- How do I find the expiration date on COOLA sunscreen?
- Check the crimp of the tube or the bottom of the bottle for a printed date or a period-after-opening (PAO) symbol. If missing, assume three years from purchase. Mark the purchase date on the bottle if you can't find a date.
- Does sunscreen expire faster if it's been opened?
- Yes. Once opened, exposure to air and bacteria can degrade the formula. Most sunscreens are best used within 6-12 months after opening. Write the open date on the cap as a reminder.
- What happens if I use expired sunscreen?
- You may not get the full SPF protection, leading to sunburn and increased skin cancer risk. It's safer to replace it. Don't risk it—fresh sunscreen is your best defense.
- How should I store sunscreen to make it last?
- Keep it in a cool, dry place, away from direct sunlight and heat. Avoid leaving it in the car. Proper storage can help maintain effectiveness until the expiration date.
