What Is Red Light Therapy?
Last reviewed: May 2026 · Haute MD Editorial Team
Red light therapy (photobiomodulation) uses specific wavelengths of red (630-700nm) and near-infrared (700-1100nm) light to stimulate mitochondrial energy production, reduce inflammation, and promote tissue repair. Evidence-based applications include wound healing, musculoskeletal pain, skin rejuvenation, hair loss (FDA-cleared LLLT), and athletic recovery.
How it works
Red and near-infrared wavelengths are absorbed by cytochrome c oxidase in the mitochondrial electron transport chain, increasing ATP production and modulating reactive oxygen species. The result is improved cellular energy and reduced inflammation in treated tissue.
Common applications
Skin rejuvenation (collagen stimulation, pigmentation), pain reduction, wound healing, hair restoration (FDA-cleared LLLT devices), and athletic recovery. Increasingly used as part of longevity and wellness protocols.
Frequently Asked Questions
Is red light therapy safe?
Yes. It is non-invasive and well-tolerated. Eye protection is recommended for sessions involving facial treatment.
How long does it take to see results?
Skin and pain applications typically show benefit within 4-8 weeks of consistent use 3-5 times per week.
Are at-home devices effective?
Reputable consumer panels can be effective if they deliver adequate irradiance at the correct wavelengths. Lower-quality devices may underdose.
