Rating (out of 5): 1

Tea tree oil (Melaleuca alternifolia) has a long history of traditional use, particularly in Australian Aboriginal medicine, for treating various skin ailments, including wounds and minor infections. The use of tea tree oil for scars and scar tissue is primarily based on anecdotal and traditional practices rather than robust scientific validation. Historically, tea tree oil has been valued for its antiseptic and anti-inflammatory properties, which may contribute to improved wound healing and potentially reduce the risk of abnormal scar formation by preventing infection and irritation. However, there is limited direct scientific evidence supporting its efficacy specifically for the treatment or reduction of established scars or scar tissue. Most modern studies on tea tree oil focus on its antimicrobial effects and its role in treating acne, rather than its impact on mature scars or keloids. A small number of laboratory and animal studies suggest tea tree oil may modulate inflammation, which could theoretically help in the remodeling phase of wound healing, but clinical trials in humans for scar treatment are lacking. As a result, while tea tree oil continues to be used traditionally for scar-related concerns, its effectiveness for this purpose is not well-supported by scientific research.
