EltaMD is an FDA-approved professional sunscreen brand that helps you protect, nourish and beautify your skin with a glowing, youthful vibrancy while enjoying the sun. Their main ingredient is zinc oxide that is a natural mineral that is safe even on the most sensitive skin, including post-procedure skin and even that of children 6 months or older. Zinc oxide blocks UVB (burning) and UVA (aging) rays that have been linked to photoaging and skin cancer.
