As the warmer months approach, it’s tempting to reach for that half-empty bottle of sunscreen from last summer. After all, sunscreen is expensive, and using what you already have seems economical. However, when it comes to sun protection, using last year’s sunscreen might not be worth the risk. Sunscreen degrades over time, losing its effectiveness and leaving you vulnerable to harmful UV rays. Factors like heat exposure and improper storage can accelerate this process, rendering your sunscreen virtually useless. In this article, we’ll explore why using expired or old sunscreen is a gamble you shouldn’t take. We’ll delve into the science behind sunscreen degradation, potential health risks, and how to properly check your sunscreen to ensure optimal protection. Don’t compromise your skin’s health; learn why fresh sunscreen is essential for safe sun enjoyment.
How do I know if my sunscreen has expired?
To check if your sunscreen has expired, look for an expiry date printed on the bottle or tube. If there’s none, note that most sunscreens last about three years unopened, but this reduces to just 12 months if the product has been used previously. Changes in texture, smell, or colour also indicate it’s time to replace it for effective sun protection.
Is expired sunscreen still effective?
Expired sunscreen is not reliably effective. Over time, its active ingredients break down, reducing its ability to protect your skin from harmful UV rays. Using expired sunscreen increases your risk of sunburn and long-term skin damage, so it’s best to replace old products with fresh, in-date sunscreen each season.
