Rating (out of 5): 2

Allicin is a sulfur-containing compound derived from garlic (Allium sativum) and has been used traditionally in various cultures for its purported antimicrobial and healing properties. The use of allicin to support or treat acne is primarily rooted in traditional medicine rather than strong scientific evidence. Historically, garlic preparations have been used topically or ingested to combat skin infections and inflammations, including acne, due to garlic's broad-spectrum antibacterial activity. This traditional usage is based on the idea that allicin can inhibit the growth of bacteria such as Propionibacterium acnes (now known as Cutibacterium acnes), one of the major contributors to acne. While in vitro studies have shown that allicin demonstrates antimicrobial activity against a range of bacteria, including those associated with acne, robust clinical trials specifically evaluating the effectiveness of allicin for acne in humans are lacking. Most evidence remains anecdotal or from small-scale studies, and there is a lack of standardized preparations and dosing guidelines. Some laboratory studies suggest allicin may reduce inflammation and bacterial growth, which theoretically could help with acne, but these findings have not yet been translated into strong clinical recommendations. In summary, while the use of allicin for acne has traditional roots and some preliminary laboratory support, scientific validation through rigorous clinical research is limited, and thus the evidence for its effectiveness in treating acne is relatively weak.
