6. Anti-Pollution
Two types of pollution dominate in the United States: ozone (a mix of sunlight and chemicals emitted by cars, power plants, and other sources) and particle (tiny pieces of solids or liquids in the air). Both can result in skin-damaging free radicals, says Tanzi.Antioxidants are very effective for protecting the skin from free radicals, so look for a formula that includes vitamin C, vitamin E, ferulic acid, or resveratrol.
