Bisabolol, a naturally occurring monocyclic sesquiterpene alcohol found primarily in chamomile (Matricaria recutita), is increasingly used in skincare formulations targeting acne. The rationale for its use is based on several scientifically studied properties: anti-inflammatory, antimicrobial, and skin-soothing effects. In vitro studies have demonstrated that bisabolol can inhibit the production of pro-inflammatory cytokines and reduce irritation in skin models, which is relevant to the inflammatory component of acne vulgaris.

Additionally, bisabolol exhibits mild antimicrobial activity, including some efficacy against Propionibacterium acnes (Cutibacterium acnes), the bacteria implicated in acne pathogenesis. Its skin-calming properties also help reduce redness and irritation, side effects commonly associated with other topical acne treatments like benzoyl peroxide or retinoids.

However, while mechanistic and cell-based evidence supports bisabolol's potential role in acne management, robust clinical trials specifically evaluating its efficacy as a primary treatment for acne are limited. Most clinical data involve bisabolol as an adjunct in multi-ingredient formulations rather than as a standalone agent. Therefore, bisabolol is best categorized as a supportive ingredient that can enhance tolerance and possibly contribute to overall skin health in acne-prone individuals, rather than a primary, evidence-based acne therapy. Further well-designed human studies are needed to clarify its direct impact on acne severity and outcomes.
