State of the Art of Photobiomodulation in Dermatology

Photobiomodulation (PBM) is a promising therapeutic technique in dermatology, particularly for conditions like acne, psoriasis, burns, ulcers, and alopecia, with an 88.4% success rate in symptom improvement across 38 studies. It uses red and near-infrared light to induce biochemical changes in tissues, showing high effectiveness and minimal adverse effects. For alopecia, PBM, especially low-level laser therapy (LLLT), significantly improves hair count, thickness, and coverage, with red light being most effective. However, the review emphasizes the need for standardized clinical protocols and further research to validate PBM's efficacy and address potential publication bias.
