Synopsis

Source of validity: Traditional
Rating (out of 5): 1

Vitamin E is traditionally used to support or treat scars and scar tissue, largely based on its reputation as an antioxidant and its widespread inclusion in over-the-counter scar creams and oils. The use of vitamin E for scars is rooted in popular and anecdotal beliefs rather than robust clinical evidence. Historically, many people have applied vitamin E oil directly to scars, believing it helps improve the appearance, soften the tissue, and speed healing. This practice has been perpetuated by word-of-mouth, cosmetic marketing, and some early small-scale studies, but it is not strongly supported by high-quality scientific data.

Scientific research on vitamin E’s effectiveness for scar treatment is limited and mixed. Several controlled studies have found no significant benefit of topical vitamin E over placebo in improving the cosmetic appearance of scars. In some cases, vitamin E has actually caused skin irritation or contact dermatitis, potentially worsening the appearance of healing wounds. Reviews from dermatological organizations generally conclude that there is insufficient evidence to recommend vitamin E for scar management. Despite this, the tradition persists, and vitamin E continues to be marketed for this use. In summary, while vitamin E is widely used for scars due to tradition, the scientific evidence supporting its efficacy is weak.
