What is SPF 30?

SPF 30 is a marking that indicates the level of protection a sunscreen has against the sun's rays. This figure means the product can help prevent sunburn 30 times more effectively than if the skin were left unprotected.
In simple terms, if your skin usually starts to turn red from the sun after 10 minutes, using a product with SPF 30 will prevent sunburn for about 5 hours. However, remember that to maintain protection, the cream must be reapplied regularly - especially after swimming or physical activity.
It's important to note that SPF 30 blocks approximately 97% of UVB rays, and increasing the SPF above this value only provides slightly more protection (for example, SPF 50 blocks about 98%).
