The Science Behind Light Therapy
Every claim we make is grounded in published clinical research. Explore the peer-reviewed studies, mechanisms, and clinical results behind LED photobiomodulation — the technology inside the Radiant Pro.
Three Wavelengths. Three Purposes.
We’ve taken advanced skincare tech out of the clinic and put it in your hands. Learn how our devices deliver real, science-backed results.
Our Breakdown
Red light therapy at 630 nanometers penetrates 2–3mm into the dermis to stimulate collagen production, improve cellular energy (ATP), and reduce the activity of collagenase — the enzyme that breaks down existing collagen.[3]
In a controlled trial of 136 volunteers, red and near-infrared light significantly improved skin complexion, reduced roughness, and increased intradermal collagen density measured by ultrasound.[1] A separate study found collagen I density increased 28% on average, with results persisting at 12-month follow-up.[3]
Our Breakdown
Near-infrared light at 850 nanometers has the deepest tissue penetration of any LED wavelength — reaching 5–10mm below the skin surface into subcutaneous tissue.[4]
At this depth, NIR light enhances mitochondrial ATP production more powerfully than visible wavelengths, activates stem cells for tissue regeneration, and reduces oxidative stress and inflammation.[6] A 2021 review in the Aesthetic Surgery Journal concluded that red and near-infrared light therapy is a "safe and effective method of skin rejuvenation."[6]
Our Breakdown
Blue light at 415 nanometers targets the skin surface to destroy Cutibacterium acnes bacteria by generating reactive oxygen species — without antibiotics, without drying, and without resistance.[5]
In a landmark randomized controlled trial, combined blue and red light achieved a 76% mean improvement in inflammatory acne lesions after 12 weeks — significantly outperforming benzoyl peroxide and blue light alone.[2] Beyond bacteria, blue light also suppresses inflammatory marker IL-1α, calming skin irritation independently of its antibacterial action.[7]
How Light Heals Your Skin
LED photobiomodulation is a process where specific wavelengths of light trigger biological changes in your skin cells without heat, UV, or chemicals.
1. Light Penetrates
Red, blue, and near-infrared photons pass through the skin and are absorbed by cytochrome c oxidase in the mitochondria — your cells' energy centers.[4]
2. Cells Power Up
Mitochondria produce more ATP — the cellular fuel that powers every biological process in your skin, from repair to collagen synthesis.[6]
3. Repair Activates
Boosted ATP triggers increased blood flow, growth factor synthesis, stem cell activation, and collagen production cascades.[4]
4. Results Emerge
Over weeks of consistent use, collagen density measurably increases, fine lines diminish, acne clears, and skin texture improves.[1]
What the Research Found
No marketing claims, just peer-reviewed findings from controlled clinical trials and systematic reviews published in medical journals.
28% average increase in collagen density
Histologic biopsies confirmed increased Collagen I in 100% of treated specimens, while MMP-1 (collagenase) decreased. Results persisted at 12-month follow-up.

76% reduction in inflammatory acne
Combined blue-red light significantly outperformed benzoyl peroxide and blue light alone in a randomized controlled trial, with no significant adverse effects.

90% showed visible photoaging reversal
Digital imaging confirmed reduction in wrinkles, redness, and pigmentation. Surface profilometry showed 10% topographical improvement sustained at 12 months.

136 volunteers in controlled collagen study
Ultrasound-measured collagen density increased significantly in treated groups vs. controls. Blinded photography confirmed visible improvement after 30 sessions.

IL-1α inflammatory marker suppressed
First in vivo evidence that 453nm blue light suppresses inflammatory markers independently of antibacterial effects — directly calming skin irritation.

3 of 3 scarring hallmarks reduced
Red LED inhibited fibroblast overproliferation, excess collagen overproduction in scar tissue, and fibroblast migration speed — modulating all three mechanisms of scar formation.

Science-backed skincare. At home.
348 LEDs. 3 clinically studied wavelengths. Professional results without the clinic visit.
Transparency note: The clinical studies cited on this page validate the wavelengths and biological mechanisms of LED photobiomodulation. The Radiant Pro uses the same clinically studied wavelengths (630nm red, 415nm blue, 850nm near-infrared) shown to be effective in peer-reviewed research. The Radiant Pro device itself has not been independently studied in a separate clinical trial.
Individual results may vary. The studies referenced represent controlled clinical conditions. LED light therapy is not intended to diagnose, treat, cure, or prevent any disease. Consult a dermatologist or healthcare provider with any medical concerns. All studies indexed in PubMed.
