Hair - - Now Trending -

Sun­screen con­tains in­gre­di­ents which fil­ter out UVA and UVB rays.s. UVA can cause pre­ma­ture skin age­ing, whilst UVB can cause burn­ingg and skin can­cer.

The Sun Pro­tec­tion Fac­tor (SPF) in sun­screen de­ter­mines how longng your skin can stay pro­tected from th­ese rays. For ex­am­ple, if it takes s 20 min­utes for your skin to burn, us­ing SPF 15 sun­screen should pre­vent red­den­ing by 15 times longer. The higher the SPF, the longer your skin should stay pro­tected.

You should ap­ply at least a shot glass full of sun­screen in or­der to achieve the full po­ten­tial of the SPF. Reap­ply ev­ery one to two hours, and af­ter swim­ming.

No sun­screen can block all UV rays.
