Should you use 30 or 50 SPF
However, in sunscreens, the industry standard, and the SPF recommended by Dermatologists is generally SPF 30 and above. A sunscreen with SPF 30 will protect you from around 96.7% of UVB rays, whereas an SPF of 50 means protection from about 98% of UVB rays.
Is there a big difference between SPF 30 and 50
An SPF 30 allows about 3 percent of UVB rays to hit your skin. An SPF of 50 allows about 2 percent of those rays through. That may seem like a small difference until you realize that the SPF 30 is allowing 50 percent more UV radiation onto your skin.
