Detailed explanation-1: -SPF is a measure of how much solar energy (UV radiation) is required to produce sunburn on protected skin (i.e., in the presence of sunscreen) relative to the amount of solar energy required to produce sunburn on unprotected skin. As the SPF value increases, sunburn protection increases.
Detailed explanation-2: -So sunscreen with an SPF of 50 means that when used on the skin, it can protect the skin against the harmful effects of UVB rays for about 500 minutes and has the ability to block the penetration of UVB rays into the body. up to 98%.
Detailed explanation-3: -SPF50 is estimated to filter 98% of UVB radiation with 1/50th (2%) reaching the skin. Both can provide excellent protection if they are applied properly. SPF50+ sunscreen still needs to be applied liberally as with any other sunscreen – see our recommendations below on how to apply it properly.
