Vitamin E, also known as Tocopherol, is a versatile antioxidant that both moisturises the skin and strengthens the skin barrier function. It also helps to stabilise certain other antioxidants and boost their effectiveness – it partners especially well with Vitamin C. Vitamin E has both humectant and emollient properties, which means it both attracts water to the skin, and helps to prevent moisture evaporation. It can soothe dryness and itching, and encourage repair, so it’s a good option if your skin is sensitive, red or reactive.
