An oil-soluble antioxidant that also occurs naturally in our skin, it helps protect our skin from free radicals and UV rays. It also has anti-inflammatory properties and can minimize the redness and inflammation symptoms associated with sun damage (source).
While Vitamin E by itself is a great antioxidant against UV damage, it truly shines when it is used in combination with Vitamin C and the synergy of both antioxidants significantly enhances their ability to protect the skin (source). This synergy can be further increased by the addition of ferulic acid which can help stabilize the ingredients (source). As such, Vitamin E (and Vitamin C) based products are great for mornings as they provide another layer of protection under your sunscreen.
Since Vitamin E is such a powerful antioxidant, it’s also frequently used as a natural preservative in food an cosmetics (source).
