Broad-spectrum sunscreen + zinc oxide = superior protection
Since SPF only indicates UVB protection, you need a broad-spectrum sunscreen, meaning the sunscreen also protects against UVA rays. However, beware not all products labeled “broad-spectrum UVA/UVB protection” provide optimum protection against UVA rays.
The four FDA-recognized sunscreen ingredients that provide adequate UVA protection are:
• Zinc oxide, an inorganic compound (composed of minerals)
• Titanium dioxide, also an inorganic compound
• Ecamsule (mexoryl SX and anthelios SX), a chemical compound
• Avobenzone (Parsol 1789), a chemical compound but one that loses 60% of its potency after one hour
What makes zinc so special?
• Zinc creates a physical barrier that reflects UV rays away from the skin
• Only zinc effectively blocks UVA1, UVA2 and UVB rays
• Micronized zinc oxide won’t degrade or lose potency over time
• And won’t produce the skin sensitivities and rashes commonly caused by chemical sunscreens
