The science of
light reaching deeper
Peer-reviewed research on red light therapy, collagen production, and photobiomodulation. Primary Wavelengths — 640nm & 690nm Red Light
Light your cells can actually use
Your skin cells run on energy. When red light at the right wavelength reaches the dermis, it's absorbed by the mitochondria — your cells' power source — and converted into usable energy. With more energy available, skin cells repair faster, fibroblasts produce more collagen, and the structural proteins that keep skin firm and smooth begin to rebuild. This process is called photobiomodulation, and it's one of the most studied non-invasive approaches in dermatology.
The velumā mask aims to deliver red light therapy at both 640nm and 690nm (plus 5 additional wavelengths), targeting the dermis where collagen is produced — the layer your skincare products usually cannot reach. Starting in your 30's, collagen production has been estimated to decrease by roughly 1% per year.
Light enters the dermis
640nm & 690nm red light penetrates to the dermal layer, where fibroblasts and collagen networks are located.
Mitochondria absorb the energy
Cytochrome c oxidase absorbs the light, boosting ATP production — the cellular fuel that powers repair.
Fibroblasts activate
Energized fibroblasts increase output of type-1 collagen and elastin — the structural proteins that keep skin firm.
Collagen density improves
With consistent use, measurable increases in intradermal collagen density have been documented in clinical settings.
Published research on red light therapy & skin rejuvenation
Photobiomodulation Reduces Periocular Wrinkle Volume by 30%: A Randomized Controlled Trial
A split-face randomized controlled trial of 137 women found that 10 sessions of red (660nm) photobiomodulation produced a 31.6% reduction in periocular wrinkle volume, measured using objective 3D imaging equipment. Both quality-of-life scores improved significantly. No adverse events were reported.
Regulation of skin collagen metabolism in vitro using a pulsed 660nm LED light source: clinical correlation with a single-blinded study
LED treatment at 660nm produced a 31% increase in type-1 procollagen levels and an 18% decrease in MMP-1 (an enzyme that degrades collagen) compared to untreated controls. Over 90% of participants showed reduced skin roughness and 87% experienced a reduction in the Fitzpatrick wrinkling severity score after 12 treatments. No adverse events reported.
Low-level red and infrared light increases expression of collagen, elastin, and hyaluronic acid in skin
LED treatment with red and infrared light significantly increased hyaluronic acid synthase (HAS2) and elastin gene expression in human fibroblasts in as little as 3 days. Also demonstrated measurable increases in collagen protein synthesis, supporting the use of low-level LED therapy for photoaging.
A controlled trial to determine the efficacy of red and near-infrared light treatment in patient satisfaction, reduction of fine lines, wrinkles, skin roughness, and intradermal collagen density increase
In this prospective, randomized, controlled study of 136 volunteers treated twice weekly, subjects showed significantly improved skin complexion, skin feeling, and profilometrically assessed skin roughness. Ultrasonographic measurements confirmed measurable increases in intradermal collagen density compared to controls.
Low-level laser (light) therapy (LLLT) in skin: stimulating, healing, restoring
A comprehensive review of laboratory and clinical studies found that red and near-infrared light stimulates fibroblast proliferation and significantly increases collagen synthesis. Identified the mitochondrial pathway (cytochrome c oxidase) as the primary mechanism of action. One of the most widely cited papers in photobiomodulation research.
