Eggs go bad and milk goes sourâ€¦ but sunscreen? Absolutely, according to the experts at BeautyBrains.com. Sunscreen formulations are delicate balances of oil and water, and if the mixture gets out of whack, the whole formula can pretty much, well, go sour. Here are a few easy ways to tell itâ€™s time to get new sunscreen before you hit the beach.
1. The consistency has changed or has separated into layers. Your sunscreen is either too thin or too thick to spread properly. Even application is crucial for good protection so if it doesnâ€™t spread right, it wonâ€™t work right.
2. The active ingredients have crystallized, making the lotion feel gritty and sandy. Donâ€™t blame the beach, your lotion has gone bad. Shaking it wonâ€™t remix the ingredients and itâ€™s time to get a new batch.
3. The sunscreen has an unusual color or smell. Yes, just like sour milk, sunscreen can take on a funny odor or color when it’s past its time. Don’t quetion, just dump it!
4 It’s past the expiration date. This might seem obvious, but just remember that if a sunscreen isn’t labeled with an expiry date, it usually has a shelf life of about two to three years.
