Throwing away expired, unused bottles of sunscreen wastes money and is harmful to the environment. But buying too many bottles at once increases your chances of having one that might degrade by the time you use it. If your expiration date isn’t on the front of the bottle, flip it over. Next, look on the back of the bottle at the top. Unfortunately, this isn't the case for all sunscreens, but some sunscreen products may bear an expiration date on the front and center of the bottle. ![]() Heat and sun can also make sunscreen less effective before the expiration date, so toss opened SPF after a year. First, look for the expiration date at the bottle’s front and center. It's always good to have extra sunscreen on hand. Even unopened bottles can expire after three years. Often, these are signs that the product is losing its effectiveness. Get rid of any sunscreen that's changed in color, smell or consistency.If you've been keeping yours in a car or beach bag, it's a good idea to buy a new supply sooner. Heat causes sunscreen to degrade and lose its potency. Replace sunscreen sooner if it's been stored in a hot place.When you do, write the purchase date on the bottle so that you'll be able to better keep up with how long you've had it. Just be sure to buy new sunscreen in its place. If it's been more than three years since you purchased it (or, if you don't remember when you bought it), go ahead and throw it out. Don't use any sunscreen past three years.Even though expiration dates aren't required, some sunscreen manufacturers choose to include them anyway.

If you're caught without any sunscreen whatsoever, fabric can provide some protection from the sun, especially if the fabric is specially woven or treated to screen out ultraviolet rays, Ploch told Live Science.

Therefore, it's impossible to say for sure how effective an expired tube of sunscreen could be, and users would be far safer seeking an unexpired option if one is available, she said. However, sunscreens can differ widely in their composition of active ingredients and inactive ingredients, and the storage history of individual containers of sunblock can vary even more. ![]() "Expired sunscreen may be better than no sunscreen, especially if the active ingredient is a physical sunblock like zinc oxide or titanium dioxide," she said. But heavy creams, which generally provide better coverage and sun protection than gels or sprays, can still provide a shield between skin and sun, even if the sunblock is expired, Ploch said. ![]() "This degradation is often accelerated by suboptimal storage conditions, so storing sunscreen in a hot car may make it ineffective even before its expiration date."Įxpired sunscreen may be less effective at blocking UV rays, raising the likelihood of sunburn and an increased risk of skin cancer. "Any ingredient in a personal care product - even inactive ones, like emulsifiers and preservatives - can degrade over time," Ploch explained. ![]()
