Vitamin E oil’s potential benefits derive from two key features: its antioxidant properties, which could fight inflammation and slow the effects of free radicals, and its moisturizing properties. Some purported benefits of vitamin E oil include: Moisturizing skin Vitamin E is found in many moisturizers, and the oil may be used as a moisturizer to prevent or treat dry, flaking skin. Wound healing Some research suggests that vitamin E supplementsTrusted Source may promote wound healing. It is possible that topical vitamin E oil might offer similar benefits, but there is little research on the subject. Skin cancer prevention A 2013 study found that mice given supplements containing vitamin E were less likely to develop skin cancer, even when exposed to large quantities of ultraviolet light. These results prompted some supporters of vitamin E oil and supplements to claim that it can prevent skin cancer. Preventing or minimizing the appearance of scars Folk wisdom has long suggested that vitamin E, applied to the skin, taken as a supplement, or both, might treat scars, or prevent them from forming in the first place. But research does not support this claim and has found no association between vitamin E use and scar prevention.
