ABSTRACT Introduction: Acne vulgaris is the most common skin disease worldwide, yet current treatment options, although effective, are associated with unwanted side effects, chronicity, relapses and recurrences. The adequate control of the four pathogenic mechanisms involved in the appearance of acne lesions is key to treatment success. This paper aims to discuss the novel treatment modalities that have surfaced in consequence of new knowledge obtained in acne pathogenesis. Areas covered: Pathogenic pathways are evaluated and discussed throughout the paper in relation to the mechanisms of action of novel molecules being investigated for the treatment of acne vulgaris. A comprehensive search was made in PubMed and Clinicaltrial.gov using a different combination of keywords, which included acne vulgaris, treatment, therapy, and therapeutic. Expert opinion: In the near future, more effective treatments with less side effects are expected. The use of topical anti-androgens, coenzyme-A carboxylase inhibitors, and insulin growth factor-1inhibitors to control sebum production seem promising. Selective RAR-agonists have the potential of becoming an alternative to the currently available retinoid therapy in the management of infundibular dyskeratosis with a better safety profile. Antibiotic use will probably decline as more effective options for controlling Cutinebacterium acnes colonization and the inflammation cascade emerge.
