HOW SUNSCREEN WORKS
Most sunscreens on the market are composed of both organic (natural) and inorganic (synthetic) chemical ingredients that, when applied to the skin either deflects or absorbs UV radiation:
Inorganic chemicals like titanium dioxide work to reflect UV rays when applied to the skin. Think of this as the first line of defense in sun protection as radiation cannot have a negative effect if it’s not absorbed by the skin.
Organic chemicals like oxybenzone and avobenzone act to absorb UV light, slowly breaking down UV radiation and releasing it as energy (heat) before it can affect the skin.
TIPS FOR CHOOSING THE BEST SUNSCREEN
Choose a sunscreen that protects against both UVA and UVB rays and has a high SPF.
Opt for a water resistant sunscreen if you’ll be active in the sun.
To protect your face without clogging your pores wear sunscreen specifically made for the facial area.
Opt for a sunscreen free of the chemical PABA (para-aminobenzoic acid)
Select a water-based sunscreen if you have oily skin.
Always check the expiration date.
