Consumer-grade LED masks that deliver red, blue, and near-infrared light to trigger cellular responses — FDA-cleared devices backed by clinical evidence for acne and anti-aging.
How It Works
LED (light-emitting diode) therapy works through photobiomodulation. Red light (630–700nm) stimulates mitochondria to produce more ATP, which signals fibroblasts to increase collagen production. Blue light (415–430nm) activates porphyrins in acne-causing bacteria (C. acnes), generating singlet oxygen that kills the bacteria. Near-infrared light (800–850nm) penetrates deeper for inflammation reduction and wound healing. At-home devices are lower power than clinical versions but effective with consistent use.
What to Expect
Use on clean, bare skin (no serums or SPF during treatment). Wear the provided goggles or keep eyes closed. Treatment time: 10–20 minutes depending on the device. Red light: 4–5x per week. Blue light: daily for acne or maintenance. Post-treatment, apply your regular serum immediately — LED temporarily increases skin permeability so products absorb better. Popular devices: Dr. Dennis Gross SpectraLite FaceWare, CurrentBody Skin LED, Omnilux Contour.
Deep Dive
LED therapy was originally developed by NASA for plant growth experiments and adapted for wound healing applications. The first FDA clearance for LED devices was in the early 2000s. Korean brands rapidly entered the at-home LED space, with devices like LG Pra.L and various Cellreturn-adjacent products. The global at-home LED market exceeded $400M in 2023. Clinical studies consistently show red light efficacy for collagen stimulation; blue light for mild-moderate acne.
