LED Therapy
Light-emitting diode treatment that stimulates collagen, reduces inflammation, and supports healing.
Evidence: moderate
LED therapy uses specific wavelengths (red 630nm, near-infrared 830nm, blue 415nm) to stimulate cellular activity, reduce inflammation, and support collagen production.
Overview
Red + near-infrared light stimulate fibroblast ATP production. Blue light kills acne bacteria.
