What Are the Benefits of Zinc Oxide?
Used topically for centuries to prevent minor skin irritations such as cuts and burns, zinc oxide is an active sunscreen ingredient that is FDA approved and widely known as one of the key ingredients in mineral sunscreens. Zinc oxide reflects and scatters UV radiation, making it a highly effective sun protectant to prevent sunburn and premature aging of skin caused by UVA rays.
Why Do We Use Zinc Oxide?
Mineral sunscreens that contain zinc oxide protect your skin from damage by reflecting as well as absorbing the sun’s rays, while chemical sunscreens chemically absorb harmful rays and prevent them from absorption. Both types of sunscreen deliver Broad Spectrum UVA/UVB protection, however because zinc oxide (ZnO) is an insoluble powder, it remains at the surface of the skin in mineral sunscreens and provides gentle non-irritating protection, making it an ideal additive for patients with sensitive skin.
