Unlocking the Power of Light on the Skin: A Comprehensive Review on Photobiomodulation
Share
This review explores the role of photobiomodulation (PBM) in skin health, healing, and dermatological applications. PBM uses visible and near-infrared light to influence cellular functions and biological processes without causing thermal damage. The article explains how PBM has gained attention for its regenerative, anti-inflammatory, and therapeutic effects in skin-related conditions.
The study highlights that PBM mainly works by interacting with cellular photoreceptors, especially within mitochondria, which can improve ATP production, regulate oxidative stress, and activate signaling pathways involved in cell repair, collagen synthesis, and tissue regeneration. These mechanisms help improve wound healing, reduce inflammation, and support skin recovery.
The review discusses PBM’s potential use in wound healing, skin aging, inflammatory skin disorders, tissue repair, and regenerative dermatology. It also emphasizes that treatment outcomes depend on factors such as wavelength, light dose, exposure time, and treatment depth.
Key takeaway: PBM shows promising benefits for skin repair and dermatological therapies, but further clinical standardization and research are needed to optimize treatment protocols and long-term applications.
