Individuals who want to heal acne scars should avoid using vitamin E, according to WebMD. Studies demonstrate that it hinders the healing process.
A study from the University of Miami found that vitamin E makes the acne scar healing process worse in 90 percent of users, and has no effect for the rest. In addition, 33 percent of study participants developed contact dermatitis when using vitamin E.
There are ways acne sufferers can promote scar healing. Not picking the scars and staying out of the sun are effective. Sunlight stimulates the production of melanin, which darkens the skin and can cause scar discoloration.
