Vitamin E is an antioxidant that can help fight free radicals, which are molecules that damage the DNA in cells. People can usually get adequate vitamin E from their diet, but it is also available in the form of supplements and skin care products.
Some companies add vitamin E to skin care products, such as oils and moisturizers. However, many claims about the benefits of applying vitamin E topically lack evidence.
Keep reading to learn about the benefits of vitamin E for the skin and its possible risks.
Vitamin E is a nutrient that the body cannot make on its own. It comes from certain foods, such as nuts and seeds, and supplements.
Vitamin E is an antioxidant, which means that it can stop or reverse the damage that free radicals cause to cells. It can also reduce inflammation around the body.
The body stores vitamin E in the skin, in both the outer epidermis and the deeper dermis layers. This is one reason why many skin care products contain vitamin E.
The nutrient lives in sebaceous glands, which form the base of hair follicles. The body transports vitamin E to the skin through sebum, an oily substance that protects and lubricates the skin.
Types of vitamin E
Vitamin E actually refers to two groups of eight vitamins. The two types of vitamin E are:
Tocopherols
These are the most abundant type of vitamin E in the human body. There are four subtypes of tocopherols: alpha, beta, delta, and gamma.
Tocotrienols
These are present in lower quantities throughout the body. Tocotrienols also have alpha, beta, delta, and gamma subtypes.
vSkin benefits of vitamin E
Some potential skin benefits of vitamin E include:
Moisturizing
Researchers have found that products containing vitamin E can moisturize the skin. However, they have not identified links between vitamin E intake and skin hydration.
Therefore, people who wish to use vitamin E as a moisturizer should stick with topical products that contain the vitamin.
Fighting UV-related skin damage
Oregan State University highlights several studies suggesting that vitamin E could fight skin damage from sun exposure. However, most of the research to date has involved animals or human skin cells in a lab setting.
It is possible that adding vitamin E to sunscreen provides some additional skin benefits, but it is important to note that vitamin E itself is not an effective sunscreen.
Wound healing
The author of a review article in the International Wound JournalTrusted Source suggests that vitamin E can promote wound healing.
The theory is that because vitamin E deficiencies can slow wound healing, a good amount of this nutrient could have the opposite effect. However, the review highlighted the lack of high quality research to support this idea.
Anti-inflammatory properties
Inflammation is the body’s reaction to an injury or infection. It can cause pain, discoloration, and swelling. Many common skin conditions cause inflammation, including acne.
A 2020 study in Scientific ReportsTrusted Source reviewed 26 clinical trials and found some evidence that vitamin E supplements reduce inflammation in adults. More high quality research is necessary to verify this finding, though.
Does vitamin E lighten the skin?
Some people use vitamin E with lemon juice or other ingredientsTrusted Source to bleach the skin. There is no evidence that this works, and these products can cause side effects that include:
damage to the skin
increased sensitivity to the sun
uneven skin tone
Many homemade skin lightening treatments that people can find online have no scientific evidence to support their use and may cause irreversible effects.
Does vitamin E help with scars?
Although vitamin E has a long history of use for healing scars, most research does not support this use.
A 2016 review of six studies concluded that there was insufficient evidence to recommend vitamin E for scar treatment. Three of the studies showed some reduction in the appearance of scars with topical use of vitamin E, while the other three showed no improvement.
The American Academy of Dermatology Association advises that keeping a wound moist could prevent the formation of scars. It recommends using petroleum jelly for this.
Summary
Vitamin E helps keep the skin healthy. People can often get enough vitamin E from food, but they can also get it in the form of supplements and skin care products.
