The active ingredients in sunscreen help prevent the sun’s UV radiation from reaching the skin. Zinc oxide (ZnO) sunscreens work by scattering the sun’s rays, preventing potentially damaging ultraviolet radiation from getting to the skin.
Is zinc oxide cancerous?
This in turn could increase the risk of skin cancer. Ma also found that the longer zinc oxide is exposed to sunlight, the greater the potential damage to human cells. “Zinc oxide may generate free radicals when exposed to UV (ultraviolet) sunlight,” May says, “and those free radicals can kill cells.”

Commercial sunscreens protect against the skin-damaging effects of ultraviolet radiation through either chemical or physical ingredients.
Is zinc oxide natural and safe?
