Is a higher SPF more effective than a low number SPF?
Not necessarily.
Dermatologists recommend using a sunscreen with an SPF of at least 30, which blocks 97 percent of the sun's UVB rays. Higher-number SPFs block slightly more of the sun's UVB rays, but no sunscreen can block 100 percent of the sun's UVB rays. So, it’s better to use an SPF 30 and reapply every 30 minutes than to just apply an SPF 100 once! Also, never underestimate the power of a good hat! 80%+ of skin aging is cause by sun exposure or sun damage. Cover up, Buttercup!
