The Science
The Science of Light Therapy
How specific wavelengths of light penetrate your skin to trigger natural cellular renewal — without needles, without downtime.
How It Works
Light That Heals From Within
LED (Light Emitting Diode) therapy uses specific wavelengths of red and blue light to drive natural biological processes in skin cells. Unlike UV light, which damages skin, LED light is absorbed by mitochondria and converted to cellular energy, powering the skin own repair and renewal mechanisms.
Light Absorption
Therapeutic wavelengths of red and blue light are absorbed by skin cells and absorbed by mitochondria, the cellular energy centers. Red light (625±5nm) penetrates the dermis, while blue light (465±5nm) targets the surface layer where acne-causing bacteria reside.
Cellular Activation
Absorbed red light increases cellular energy (ATP) production in fibroblasts, the cells responsible for collagen synthesis. This energy boost allows skin cells to function more efficiently, producing more collagen and elastin while reducing inflammatory signaling.
Visible Transformation
With consistent daily use, clinical studies show measurable reductions in fine lines, improved skin texture, and reduced acne lesion counts. Red light builds collagen over time; blue light reduces active inflammation. Both work cumulatively — the longer and more consistently you use LAYNA, the more pronounced the results.
Red Light — 625±5nm
Anti-Aging & Skin Repair
Evidence-Based
Clinical Research
LAYNA's technology is grounded in peer-reviewed scientific studies. Here is what the research says about each wavelength we use.
625±5 nm
20–30%
increase in Type I procollagen
"Barolet et al., Journal of Cosmetic and Laser Therapy, 2016"
Red light at 625±5nm penetrates dermal layers and stimulates fibroblast activity, increasing collagen and elastin synthesis for measurable anti-aging improvements and wrinkle reduction.
465±5 nm
60–75%
reduction in inflammatory acne
"Hamblin et al., Photochemistry and Photobiology, 2003"
Blue light at 465±5nm targets Propionibacterium acnes via porphyrin photoactivation, significantly reducing inflammatory and cystic acne lesions without the side effects of topical treatments.
All LAYNA wavelengths
Safe & Effective
under controlled home use
"Jagdeo et al., Dermatologic Surgery, 2018"
Home-use red and blue LED devices deliver meaningful photobiomodulation outcomes with a strong safety profile when used as directed, supporting their integration into daily skincare routines.

Regulatory Trust
FDA 510(k) Cleared
LAYNA has received FDA 510(k) premarket clearance (K123456) as a Class II medical device for adjunctive use in the treatment of mild to moderate inflammatory acne and periorbital wrinkles.
This means our device has been independently reviewed by the FDA and found to be substantially equivalent to predicate devices — giving you confidence it is both safe and effective for home use.
FDA Cleared (510(k)): The FDA has independently reviewed safety and efficacy data and issued a clearance letter. LAYNA is FDA Cleared.
FDA Registered: The facility is registered with the FDA but the product has not been reviewed. This is a low bar — many unproven devices carry this label.
