Laser and light-based therapies for acne vulgaris: a current guide based on available data

There are some patients that, despite their continued use of optimized topical and systemic medication and skin care regimens, exhibit at least partial persistence of acne vulgaris (AV) lesions that is bothersome and treatment-resistant to pharmacologic approaches. Additionally, professional, public and governmental concern regarding "antibiotic resistance" has led to interest in therapeutic alternatives other than antibiotics. These challenges drive research into non-pharmacologic approaches to AV treatment, including laser and light-based approaches.
