Vitamin E for skin: benefits, side effects and the scar myth

Vitamin E is an antioxidant and emollient. On skin it helps neutralize free radicals from UV light and pollution, softens dry patches, and makes vitamin C serums more stable and effective. In products it also stops oils from going rancid. It does not fade scars, and a small number of people are allergic to it.

What vitamin E does for your skin

Vitamin E is the name for a family of fat-soluble compounds. The form your body keeps and uses most is alpha-tocopherol. Your skin already contains it, and much of it reaches the surface through sebum, the oil your skin makes. That is why oilier areas such as the face tend to have more of it.

• Antioxidant: it neutralizes free radicals, unstable molecules made by UV light and pollution that damage skin lipids and contribute to skin aging. Applied to skin, vitamin E generally adds some protection against UV damage in studies.
• Emollient: as an oily ingredient it softens and smooths rough, dry skin and helps the surface hold on to water.
• Partner for vitamin C: vitamin C helps regenerate vitamin E, and the two protect better together than either one alone.
• Product protector: formulators add a little tocopherol to creams, balms and oils so the plant oils inside don't oxidize and turn rancid. This is why you see it on so many labels, often near the end of the list.

Tocopherol vs tocopheryl acetate on the label

On an ingredient list (INCI), vitamin E usually appears in one of two forms. The difference matters more than you might think. If you are new to INCI names, our guide on how to read cosmetic ingredient labels walks you through the basics.

Research summarized by the Linus Pauling Institute suggests that skin converts very little of the ester forms into active vitamin E, and that free tocopherol has given the most consistent results in topical studies. In practice, tocopheryl acetate is still a useful moisturizing and conditioning ingredient, but if you want vitamin E for its antioxidant effect, a well-packaged tocopherol product (opaque, airtight) is the better bet.

Vitamin E with vitamin C and ferulic acid

The best-studied use of topical vitamin E is in antioxidant serums. Vitamin C (L-ascorbic acid) is notoriously unstable, and pairing it with vitamin E helps. In a laboratory study on skin, adding ferulic acid, a plant antioxidant, to a solution of 15% vitamin C and 1% vitamin E made the vitamins more chemically stable and doubled the protection against simulated sunlight, from about 4-fold to about 8-fold, measured by redness and sunburn cells.

This is why "C E Ferulic" style serums are popular. They are applied in the morning under sunscreen, and the combination adds a layer of defense rather than replacing SPF. Read more about choosing and storing these serums in our vitamin C serum guide.

Is vitamin E good for dry skin?

It can help, mostly because it is an oil. Like other emollients, vitamin E fills gaps between rough skin cells and slows water loss, so dry skin feels softer. A couple of small studies found that topical vitamin E improved the skin's ability to hold water after two to four weeks, but researchers note that the evidence is limited. Eating more vitamin E has not been linked to better skin hydration.

For dry or flaky skin, vitamin E works best as one ingredient in a moisturizer alongside humectants like glycerin and barrier lipids like ceramides, rather than as the star of your routine. See our guides to dry skin on your face and repairing your skin barrier for a full plan.

Does vitamin E oil heal scars? The evidence says no

Breaking open a vitamin E capsule over a scar is one of the most widespread skincare habits, and one of the least supported. In a double-blind study, people who had skin cancer surgery applied a plain ointment to one half of their scar and the same ointment mixed with vitamin E to the other half. In 90% of cases, vitamin E either made no difference or made the scar look worse, and 33% of patients developed contact dermatitis (an itchy rash) from it. The authors advised against using vitamin E on surgical wounds.

A later systematic review found only six good-quality studies. Three reported some benefit, mostly when vitamin E was combined with other treatments, and three found none. The reviewers concluded there isn't enough evidence to justify using vitamin E on its own for scars. If a scar bothers you, ask a dermatologist about options with better evidence, and protect healing skin from the sun.

Vitamin E allergy and side effects

Most people use vitamin E without any problem, and true allergy is relatively rare given how common it is. In a large North American study of almost 39,000 people patch tested for skin allergies, 0.9% reacted to tocopherol or tocopheryl acetate, most often from moisturizers. Reactions tended to show up on the face or scattered across the body.

• Signs of a reaction: redness, itching, bumps or flaking where you applied the product, sometimes appearing a day or two later.
• Higher risk: pure vitamin E oil or high concentrations applied to broken or freshly healing skin, as in the scar study above.
• If you react: stop the product, let your skin settle, and see a dermatologist if the rash persists. Patch testing can confirm whether vitamin E is the culprit, and then you can avoid it on labels.

If you have sensitive or allergy-prone skin, patch test new products on a small area first. Our sensitive skin guide explains how, and the guide to fragrance allergens covers the ingredients that cause reactions far more often.

Does vitamin E clog pores?

Vitamin E as an ingredient in a light lotion or serum is unlikely to be the main problem for most people. Pure vitamin E oil is different: it is very thick and sticky, and it is often sold blended with heavier carrier oils. On acne-prone or oily skin, a heavy oil left on the face can contribute to breakouts. If you break out easily, choose lightweight products labeled non-comedogenic and skip straight vitamin E oil on your face.

How to use vitamin E in your routine

1. Get it from a finished product, such as a vitamin C and E serum or a moisturizer, rather than from capsules.
2. Use an antioxidant serum in the morning on clean skin, then moisturizer and sunscreen.
3. If your skin is very dry, a moisturizer or balm with vitamin E at night can add extra softness.
4. Store serums away from light and heat and close them tightly. If a vitamin C and E serum turns dark orange or brown, it has oxidized.
5. Avoid putting pure vitamin E oil on fresh wounds, stitches or new scars.
