The Sun Protection Factor (SPF) number is not an accurate determination of a sunscreen's capability of protecting the skin from the sun's harmful rays. SPF is only an indication of protection from one wavelength of Ultraviolet light, the UVB (290nm*-320nm). UVB is the cause of early skin redness experienced during initial sun exposure. UVA (320nm - 400nm) is responsible for deeper skin damage, and many of the long term destructive changes that are harmful to the skin. Unfortunately there is no official rating system, to date, that measures a product's UVA protection.
