What is the shelf life of sunscreen?

Depending on your vacation destination, its geographical area, and the weather conditions, sunscreen can be completely used up in one summer or remain almost untouched.

However, regardless of how much you use or how full it is, sunscreen should only be kept for one summer. That said, if you go out in the sun several times, it is possible to keep your sunscreen until its expiration date.

Each summer, its own sunscreen
Why is it recommended to keep your sunscreen for only 2 or 3 months? Sunscreen is often stored in harsh conditions: long exposure to the sun, heat, possible contact with sand...

To remain effective and filter both UVA and UVB rays, cosmetics—whether foundation, day cream, or sunscreen—should not be exposed to extreme temperatures. These conditions can prematurely and rapidly degrade sun care products.

Sunscreens, especially sprays, are often directly exposed to light, even if the packaging is opaque. In addition, by the pool or at the beach, the products often come into contact with water, which encourages the growth of bacteria.

How to properly store your sunscreen for a few months?
With the open jar symbol, which indicates the number of months the product can be used after opening, sunscreen generally keeps for 6 months, even though it is recommended to throw it away after 3 months.

To extend the shelf life of your sunscreen up to 6 months, it is advised to keep the products in the shade of a parasol or in a cool, dry place, avoid contact with sand which brings microbes, and make sure to close it tightly after use to minimize contact with air.
