I once found an old bottle of sunscreen tucked away in the back of my cupboard and thought, “Hey, it’s just sunscreen; how bad can it be?” Well, sunscreen does have an expiration date for a reason, even if it seems like it never really expires! Sunscreen is like that friend who always needs a little extra attention—over time, it can lose its potency and might not protect you as well as it used to. Did you know that the effectiveness of sunscreen can drop significantly after a few years? So while slathering on expired sunscreen might not turn you into a tomato, it’s probably worth getting a fresh bottle if you want to stay sun-safe. Plus, it gives you an excuse to shop for new summer gear!
