Understanding Sunscreen Expiry
Sunscreen is an essential part of protecting your skin from harmful UV rays, particularly during the sunnier months. However, one aspect that is often overlooked is whether sunscreen can expire. This is an important factor to consider, as using expired sunscreen can significantly reduce its efficacy, leaving your skin vulnerable to sun damage.
How To Check the Expiry Date
In the UK, sunscreen products often include an expiry date or a Period After Opening (PAO) symbol on their packaging. The expiry date is straightforward – it indicates the point at which the product is no longer guaranteed to be effective. The PAO symbol, represented by an open jar icon with a number inside, indicates how many months the product will remain effective after it has been opened. For instance, a '12M' indicates that the sunscreen is safe to use for 12 months after opening.
Factors Affecting Sunscreen Expiry
Several factors can affect the expiry of sunscreen. Exposure to heat and sunlight can cause ingredients to break down more quickly. Storing sunscreen in a cool, dark place will help extend its shelf life. Additionally, the frequency with which a sunscreen is opened and closed can introduce air and bacteria into the product, potentially decreasing its effectiveness over time.
Risks of Using Expired Sunscreen
Using expired sunscreen can expose your skin to the risk of sunburn, premature ageing, and increased risk of skin cancer. Expired sunscreens may lose their stability and fail to provide the protection specified on their labels. It's important to pay attention to any changes in colour, consistency, or smell, as these can be indicators that a sunscreen is past usable condition.
Best Practices for Sunscreen Use
To ensure you are always protected, consider buying sunscreen in smaller quantities so that it can be used within its PAO time frame. Always check the expiration date when purchasing sunscreen, and avoid stocking up unless you are sure you'll use it all before it expires. Additionally, keep your sunscreen in a stable environment, away from heat and direct sunlight, to preserve its efficacy.
Conclusion
In conclusion, sunscreen does expire, and using it past its expiration date can compromise your skin's protection against harmful UV rays. By understanding how to read expiration dates and proper storage practices, you can ensure that your sunscreen remains effective, helping to keep your skin safe and healthy.
Understanding Sunscreen Expiry
Sunscreen helps keep your skin safe from the sun. But did you know sunscreen can go bad? Old sunscreen might not work well, leaving your skin at risk of getting hurt by the sun.
How To Check the Expiry Date
Look for a date or a little jar picture on the sunscreen bottle. The date tells you when it stops working well. The jar picture with a number, like '12M', means the sunscreen is good for 12 months after you open it.

Old sunscreen might not stop sunburns, and can increase the chances of skin problems. If it looks a different color, feels strange, or smells bad, it might be old and not good to use.
Best Practices for Sunscreen Use
Buy small amounts of sunscreen, so you use it before it goes bad. Check the date before buying. Keep sunscreen away from heat and sunlight to make it last longer.
Conclusion
Sunscreen does go bad, so you need to check dates and store it right. This way, your sunscreen will keep your skin safe and healthy.
