Where's the Evidence? A Critical Evaluation of Common Cosmetic Recommendations - Lasers for Acne

In a review of various acne treatments, the speaker highlights that current evidence does not support any specific alternative treatment, such as lasers, being more effective than traditional methods. However, blue light therapy has shown promise for mild to moderate acne. High-dose photodynamic therapy (PDT) has demonstrated effectiveness for clearer skin, especially when utilizing longer incubation times and higher concentrations of ALA. The presentation discusses the efficacy of new selective lasers targeting sebaceous glands, highlighting two recently FDA-approved devices that utilize 1726 nanometers of light for acne treatment. These devices differ in cooling mechanisms and treatment protocols, but both show significant patient clearance rates, with purported long-lasting effects. Both PDT and retinoids are noted as possible combinations for enhanced treatment outcomes. Overall, the advancements in laser technology and photodynamic therapy represent a shift towards more effective acne treatments that may promise better results than conventional therapies.
