Vitamin E (Tocopherol)
Tocopherol · Tocopheryl AcetateAntioxidant
Lipid-soluble antioxidant. Routinely paired with vitamin C — they regenerate each other and each scavenges different free radicals.
What it does
Vitamin E protects the lipid portion of the skin barrier from oxidative damage. The classic combination is vitamin C + vitamin E + ferulic acid (the 'CE Ferulic' formulation), which has stronger photoprotective evidence than any of them alone.
