Vitamin C vs Vitamin E
Vitamin C vs Vitamin E — two antioxidants that support skin against oxidative stress in complementary ways, where vitamin C is a water-soluble antioxidant also involved in brightening and collagen-related processes, and vitamin E is a fat-soluble antioxidant that helps protect skin lipids. They are often formulated together because they work synergistically.
Key points
- Vitamin C, such as L-ascorbic acid, is water-soluble and studied for antioxidant defense and a brightening effect on uneven tone.
- Vitamin E, mainly tocopherol, is fat-soluble and helps protect the skin's lipid barrier from oxidation.
- The two antioxidants are known to work synergistically, and vitamin E can help stabilize vitamin C in formulas.
- Many antioxidant serums combine vitamin C and E, sometimes with ferulic acid, to enhance stability and performance.
