Blog Alert: LED Photobiomodulation (PBM)
LED Photobiomodulation (PBM) is a non-invasive light-based therapy that uses specific wavelengths of visible and near-infrared light to influence cellular behaviour in the skin. Unlike heat-based or ablative devices, PBM works at a biochemical and cellular signalling level, supporting skin function rather than forcing change. At the core of photobiomodulation is the interaction between light photons and cellular chromophores, particularly within the mitochondria. When cells absorb the correct wavelength at an appropriate dose, this light energy can suhttps://www.salonsetup.co.nz/online-led-light-therapyhttps://www.salonsetup.co.nz/online-led-light-therapypport mitochondrial efficiency, ATP production, nitric oxide regulation, and downstream cellular communication involved in repair, inflammation control, and tissue regeneration. Different wavelengths produce different biological responses: - Blue light is primarily used for acne-prone skin due to its interaction with porphyrins produced by Cutibacterium acnes. - Red light supports fibroblast activity, collagen synthesis, circulation, and inflammation modulation. - Near-infrared light penetrates more deeply, influencing tissue repair, wound healing, lymphatic flow, and neuromodulation. Importantly, LED photobiomodulation is dose-dependent. More light is not better. Effective outcomes rely on correct wavelength selection, irradiance, treatment time, frequency, and appropriate client selection. When misused, PBM can be ineffective—or in some cases counterproductive—highlighting the importance of practitioner education. In professional skin practice, LED therapy is best understood as a supportive and regulatory modality. It enhances outcomes when integrated with treatments such as microneedling, chemical peeling, barrier repair protocols, acne management, and post-procedure recovery—rather than acting as a standalone “quick fix.” Our training focuses on:
