Light Therapy Modalities in the Management of Acne.

Much like the update in the classification of the acne commensal from Propionibacterium acnes (P. acnes) to Cutibacterium acnes (C. acnes), the treatment of acne has observed advances, augmenting topical and oral medications, including anti-microbial peptides, chemical peels, microencapsulated medications, and probiotics. The traditional paradigm of acne treatment has its limitations, such as skin irritation, photosensitivity, concern over antibiotic resistance, and regimen complexity. Given these challenges, discussing alternative options for acne treatment in detail is important. Light therapy, in particular, is an emerging modality that has transformed the landscape of acne management and thus merits additional discussion (Table 1).
