What is an antioxidant, and why is SkinCeuticals the authority? With four generations of topical antioxidant formulations, 10 patents, and more than 200 studies published in prestigious medical journals, SkinCeuticals is a trailblazer in antioxidant science.
Properly formulated topical antioxidants have been shown to neutralize skin-damaging free radicals. Some improving the appearance of fine lines, wrinkles, and discoloration. But what are antioxidants, how do they work, and what other benefits do these active molecules have for the skin?
What is an antioxidant?
An antioxidant is a molecule that inhibits the oxidation of other molecules.
Oxidation is a type of damage that occurs when molecules lose electrons. Five types of antioxidants found naturally in the body that protect against cellular damage are: glutathione, ubiquinone, ascorbic acid (vitamin C), alpha tocopherol (vitamin E), and alpha lipoic acid. Antioxidants work by different mechanisms to stop or neutralize damage. Out of the five antioxidants found in the body only vitamins C and E have been proven to get into skin. Additionally, there are a few plant antioxidants known to work in skin.
What’s a free radical?
Free radicals are molecules with unpaired electrons, causing them to be unstable and highly chemically reactive.
These unstable molecules are generated by UV rays, pollution, and lifestyle factors like alcohol and cigarette smoke. Over time, free radical damage leads to visible signs of accelerated skin aging, including fine lines, wrinkles, laxity, discoloration, and even skin cancer.
While sunscreen is the first line of defense and essential for protecting skin from UVA and UVB rays, sunscreen rays filters may only protect skin from up to 55% of free radicals*. Topical antioxidants work to neutralize free radicals and protect against UV damage. Incorporating a topical antioxidant and sunscreen into a daily skincare regimen provides complete protection from environmental damage.
