Sunscreen is a non-negotiable in any sun protection routine, but did you know that it has an expiration date? Using expired sunscreen can leave your skin vulnerable to harmful UV rays, increasing the risk of sunburn, premature aging, and even skin cancer. Here’s how to know when to replace your sunscreen bottle and ensure you’re always protected.
Check the Expiration Date
Most sunscreens have an expiration date printed on the bottle, typically two to three years from the manufacturing date. If your sunscreen is past this date, it’s time to toss it—expired formulas lose their effectiveness, meaning they won’t shield you from UVA and UVB rays as well as they should.
Look for Changes in Texture and Smell
If your sunscreen has separated, become watery, lumpy, or grainy, it’s a sign that the ingredients have broken down. Additionally, an off or rancid smell is a clear indicator that the formula is no longer good. Even if the expiration date hasn’t passed, any noticeable changes mean it’s time for a new bottle.
Consider Storage Conditions
Sunscreen should be stored in a cool, dry place. If you’ve left it in a hot car, on the beach, or exposed to direct sunlight for extended periods, the heat may have degraded the active ingredients, making it less effective. If you’re unsure, it’s safer to replace it.
If in Doubt, Replace Annually
Even if your sunscreen isn’t expired, replacing it at least once a year is a good rule of thumb—especially if you use it frequently. A single bottle shouldn’t last multiple summers if you’re applying the recommended amount (about a shot glass full for the body).
Signs Your Sunscreen Isn’t Working
If you’re applying sunscreen correctly but still getting sunburned, your sunscreen may have lost its effectiveness. This could be due to expiration, improper storage, or not applying enough. To stay protected, always apply generously and reapply every two hours.
The Bottom Line
Sunscreen is your skin’s first line of defense against UV damage, but only if it’s fresh and effective. To avoid sunburn and long-term skin damage, replace expired or compromised sunscreen immediately. And if you’re looking for additional sun protection, consider high-quality UPF clothing, which offers built-in protection without the need for reapplication.
