![]() ![]() The FDA recommends never exposing your sunscreen container to direct sunlight or excessive heat! Sunscreens kept in a beach bag, hot car, sitting out in direct sunlight will have a shorter shelf life. Storing sunscreen in hot conditions and direct sunlight is pretty much what we do with all sunscreen except the one we put on in the bathroom at the start of our day. That being said, it should never smell rancid." If you're dealing with any of these signs, it doesn't always mean the sunscreen actives aren't effective-according to Gracia, it does mean that "the delivery system has been compromised, which signals that the actives won't be delivered in a uniform layer to provide adequate protection, or that the preservative system is no longer working to stop contamination like mold, yeast, or bacteria.Many of the chemical active ingredients (called UV filters) are notoriously unstable and breakdown quickly, especially if you store your sunscreen in the direct sun or in excessively hot conditions. "It's also important to note that there's going to be some variance in smell when using natural aromatic extracts. Then there's the scent: "If a formula doesn't smell like it typically does, there might be an issue with it," she says. "For example, when squeezing a lotion out of a tube, you may notice there's an oily substance that comes out separately." This isn't good. "If the formula's no longer uniform in texture is one warning sign," she says. "And all manufacturers make formulas to comply with this, since SPFs are OTC drugs." Since that date comes from the moment it comes off the manufacturing line, it's smart to simply expect that your SPF will be good for a year from when you get it.Īlso, in the case that your product doesn't show a date on it, Gracia says there are tell-tale signs you can watch out for that can indicate it's expired. ![]() "Regardless of the SPF actives used in a product, the FDA doesn't allow more than a three-year expiration date from the day of manufacture," says Dr. ![]() Whichever sunscreen you're dealing with, whether mineral or chemical, tends to have an expiration date that's no further than three years out from the date it was manufactured. "Sunscreens are classified as an 'over-the-counter drug' (OTC), and because of this, the FDA requires that they have an expiration date." -Dr. " the formula itself, or how well a product is formulated, stabilized, and how effective its preservative system is the packaging, including how compatible the materials are with the formula and how well they protect it from the environment during storage and use and the raw materials-for instance, natural ingredients like oils, butters, and extracts have a shorter shelf life and are also much more sensitive to light and air exposure," says Gracia. And that expiration date depends on a couple of factors including the formula and the product packaging, according to Sofia Gracia, director of product development at Supergoop! "Sunscreens are classified as an 'over-the-counter drug' (OTC), and because of this, the FDA requires that they have an expiration date," says Loretta Ciraldo, MD, FAAD, dermatologist and founder of Dr. But, as I grabbed whatever was leftover from summer 2018, something I forget to pay attention to is the fact that sunscreen can expire. I don't even think twice about it-I simply grab whatever SPF is nearest to me and swipe it all over my face. By now, the skin-care commandment that says you should be wearing sunscreen every single day is so ingrained in my brain that I practically apply it every morning with my eyes closed.
