Creams with the SPF filter protect the skin against the negative effects of the sun, among others Burn, which is not difficult, especially on the beach. However, these cosmetics have their useful terms – usually their religious date for use since purchase is several years. However, sometimes we forget that After opening, it can be used for only a few months, after which it loses its properties.
Products with a sunscreen allow you to protect the skin from the sun, which contributes, among others for faster skin aging or discoloration. Their use is important, but like all other cosmetics, they have their usefulness after opening. SPF creams can usually be used for about 6 months after opening. After this time, the ingredients contained in them begin to break down, the product formula changes, lumps may appear, and the protective properties themselves significantly decrease.
On cosmetics you will find two dates – usefulness is usually a few years after producing the cosmetic and the expiration date after opening (the symbol of the open jar in which the number is indicated) means how many months after opening SPF you can use it. Thus, if we opened the cream last year and did not use it, it should not be taken on vacation in 2025, because its action will no longer be effective. Thus, we will not provide the skin with adequate protection.
It is also worth remembering that cosmetics kept in the sun can break faster, so if we take creams to the beach and leave it in the sun, then its properties will often escape earlier.
