Vitamin E

Vitamin E (D-alpha-tocopherol; DL-alpha-tocopherol; tocopherol) — considered the most important oil-soluble anti-oxidant and free radical scavenger. Studies indicate that vitamin E performs these functions when topically applied. It is also a photo-protectant, and it helps protect the cellular membrane from free-radical damage.

As a moisturizer, vitamin E is well-absorbed through the skin, demonstrating a strong affinity with small blood vessels and an ability to enhance blood circulation in the skin. It is also thought to improve the skin’s water-binding ability. In addition, vitamin E emulsions have been found to reduce trans-epidermal water loss, thereby improving the appearance of rough, dry, and damaged skin.
