Dermatologist Shereene Idriss explains when to throw out sunscreen. If it separates or gets chunky, toss it: expired sunscreen won't protect evenly and leaves you vulnerable to sunburn, wrinkles, and skin cancer.
If your sunscreen looks like this, it's time to throw it out. I'm a board certified dermatologist and let's talk expired sunscreens. Unlike other products, skin care products. The reason why it's so important to avoid expired sunscreens is because they're no longer doing the work that they are intended to do, which is to protect your skin. You're basically playing Russian roulette with your skincare each time you apply it. When a product is visibly chunky or separated, it means it is not homogenous or uniform. Applying it will lead to an uneven distribution of your protective ingredients which will result in either a burn or premature wrinkles or unwanted skin cancer. And although you can probably shake it and it will look better in the process, the damage is already done, the product has already separated. And even though I'm a firm believer in using unwanted products in other parts of your body, when it comes to expired sunscreen, just suck it up, swallow the sun cost and move on with your life.
