What SPF Actually Is?
Sunscreen SPF(sun protection factors) works by how much spf you use it. It works when you wear sunscreen rightly.
Example:
Spf 30 protected skin from sunburn about 30 minutes longer than usual, if you wear no sunscreen. It protect skin about 97% of sun rays .
SPF 50 protected skin slightly greater than Spf 30 , not double but slightly greater level.
The evidence reveals:

- SPF 50 protect skin from about 98% of sun rays, improve glow in skin, but not have very large difference from Spf 30
Higher SPFs block more slowly, but never completely. This is why reapplication matters as much as SPF number.
