What is PDT LED?
PDT (Photodynamic/Photobiomodulation) LED uses specific wavelengths that interact with skin chromophores to modulate cell activity and inflammation. In professional devices, common options include red (~633 nm) for glow and regeneration, blue (~415 nm) for acne-prone skin, and near-infrared (~830 nm) for comfort and tissue recovery. Configuration may vary by model.
