Shelf life of sunscreen: what to keep in mind
The spring sun is particularly aggressive for our untanned skin. In order to avoid skin damage with consequences such as an increased risk of skin cancer, adequate protection in the form of sun cream is extremely important. But somehow warm temperatures always surprise us relatively suddenly - and a new sun care product is not yet at hand. Can we still use the product from last year?

Use by date for sun protection products
Sun creams also have an expiration date. As a widespread misconception would lead us to believe, the UV filter does not disappear over time! Rather, the drainage of the product is due to the ingredients - such as fat that becomes rancid or water that colonizes germs. The best before date of your product can be read from the symbols on the packaging. There are also certain factors that we can use to influence the shelf life of creams and lotions.

Shelf life for sunscreen: read symbols correctly
An hourglass is often depicted on sun protection products. This is always combined with a classic best-before date, similar to food. It provides information about how long a product can be used if it is generally stable (when closed) for less than 30 months. The time information that can be found here applies regardless of the first opening!
If a cream jar is shown on the product, this basically means that it can be kept for at least 30 months unopened. There is also the symbol of the opened cream jar with a number inside. This indicates how long the product can be used after it has been opened for the first time. Usually this is a shelf life of between three and 30 months.
Storage: This is how sunscreen lasts
As with food, when it comes to sun protection, the best-before date does not indicate the day when the product will expire. The creams usually have a longer shelf life. Conventional sunscreens usually last between 12 and 14 months, so they can normally be used over two summers without hesitation. Be sure to look out for signs of quality such as smell and consistency. If the lotion is watery, crumbly or smells unpleasant - throw it in the trash!
In order to maintain the shelf life of the sun care as long as possible, you can consider a few things when storing and using it:
- Avoid extreme temperatures and direct sunlight. So don't even leave your sunscreen next to the hammock in the blazing sun.
- If the pack has survived last summer well, it is best to store the sun protection in the basement or another cool, dark and dry place until the next spring arrives.
- When using the products, avoid germs getting into the packaging. With direct finger contact on the opening or dirt in the lid, nasty bacteria can quickly reduce the quality of the sunscreen and make it unusable by next summer. Avoid direct skin contact, for example with spray bottles or by squeezing out the lotion.
If you follow these tips, you can usually use your sun care product for two or three summers without any problems. However, do not skimp on the amount when applying to ensure sufficient UV protection.
