Does vitamin E oil help scars?

The evidence is weak. A 2016 review found 6 prospective studies of vitamin E put on the skin for scars. Three found that scars looked better: one used vitamin E alone in children, and two used it with other treatments in adults. The other three found no effect of vitamin E alone.^[1] Two studies reported skin reactions: contact dermatitis, itching and rash.^[1] The authors concluded that the evidence is not enough to support its wide use.^[1]
