Combination blue (415 nm) and red (633 nm) LED phototherapy in the treatment of mild to severe acne vulgaris.

Abstract in brief

• The study explores the effectiveness of a combination of blue (415 nm) and red (633 nm) LED phototherapy for treating mild to severe acne vulgaris, showing significant reductions in lesion counts over 12 weeks with minimal side effects.
• Twenty-four patients participated, receiving eight sessions of LED therapy with prior microdermabrasion, resulting in notable improvements, especially in inflammatory lesions, with both patient and dermatologist assessments aligning.
• The therapy is described as safe, painless, and promising, with severe acne responding slightly better and comedones being less responsive compared to inflammatory lesions.]
