Ajoene is a sulfur-containing compound derived from garlic (Allium sativum) and has been investigated for various medicinal properties, including antimicrobial and anti-inflammatory effects. The use of ajoene for acne is primarily supported by preliminary scientific evidence rather than traditional use. Several in vitro studies have demonstrated that ajoene possesses antibacterial activity against Propionibacterium acnes (now Cutibacterium acnes), the bacteria implicated in acne pathogenesis. Additionally, ajoene exhibits anti-inflammatory effects, which may help reduce redness and swelling associated with acne lesions.

Small-scale clinical studies and case reports suggest topical ajoene gel (typically at 0.4% concentration) may improve mild to moderate acne, with observed reductions in lesion counts and inflammation. However, the quality of evidence is limited by the small sample sizes, lack of large randomized controlled trials, and variability in study design. No major side effects have been reported in these studies, though garlic derivatives can sometimes cause skin irritation.

In summary, there is early-stage scientific support for the use of ajoene in acne, grounded in its antimicrobial and anti-inflammatory actions. However, more robust clinical trials are necessary to establish its efficacy and safety conclusively. Until then, its use remains experimental rather than standard in dermatological practice.
