Does Sunscreen Expire? Here’s What You Need to Know for Optimal Protection!
The short answer: yes, sunscreen does go bad, and relying on an expired bottle is like using an umbrella full of holes — it might offer some coverage, but not enough to keep you protected. Over time, heat, light, and exposure to air break down sunscreen’s active ingredients, making them less effective at blocking harmful UV rays. Using expired sunscreen can leave your skin vulnerable to sunburn, premature aging, and even long-term damage.
