What is vitamin E?
Vitamin E applied to the skin acts as an antioxidant, protecting it from damage. It is hydrating and helps the skin absorb and retain water.
1. Identification and Nomenclature
- INCI Name: Tocopherol (for natural Vitamin E), Tocopheryl Acetate (for synthetic Vitamin E)
- Common alternative names: α-Tocopherol, D-alpha-tocopherol, DL-alpha-tocopherol
- How to identify on product labels: Look for “Vitamin E,” “Tocopherol,” or “Tocopheryl Acetate”
2. Origin and Sourcing
- Natural sources: Vegetable oils (soybean, sunflower, corn), wheat germ, nuts, seeds
