Sun protection factor, or SPF, refers to a grade that ranges from 15 to 50 and reflects how well a product protects against the sun. A sunscreen's SPF rating shows how much UV light it will prevent if used as directed. A sunblock with SPF 15 protects against the sun's rays, for instance, for 14 of every 15 of them, or 93%. SPF 50+, on the other hand, is effective against at least 98% UV rays.
