How should sunscreen be applied....
*Apply to dry, clean skin.
*Apply generously - for an adult, apply about a teaspoonful to each arm and leg, and a teaspoonful to the face, neck and ears
*Apply twenty minutes before exposure.
*Re - apply at least two hourly.
*Re - apply more often if sweating or toweling dry.
*Use with other forms of sun protection.
SPF - stands for sun protection factor (refers to the amount of protection a sunscreen offers). SPF 30 + provides the best protection.
Broad spectrum - protects the skin from both UVA and UVB radiation. All sunscreens with an SPF number will filter out the UVB part of ultraviolet (UV) radiation.
Water resistant - does not immediately dissolve in water but is not like a waterproof watch, i.e.the sunscreen does come off.
Sunscreen should not be used to increase the time you spend in the sun - it does not completely block UV radiation and should be used as the last form of protection
