From surface skin at 630nm to deep tissue at 1060nm—understand how each wavelength in our Bio-Spectrum targets specific biological processes.
Different wavelengths reach different tissue depths. Visible red light treats the skin surface, while near-infrared penetrates to muscles, joints, and beyond.
Therapeutic light penetration depths through human tissue layers. The 1060nm wavelength (dashed) represents invisible deep infrared.

Therapeutic Wavelength Spectrum
Click a peak to explore
The Verso Bio-Spectrum includes 8 therapeutic wavelengths: 630nm (surface rejuvenation, targets epidermis), 650nm (cellular repair, targets upper dermis), 660nm (collagen production, targets dermis with peak cytochrome c oxidase absorption), 670nm (circulation, enhances blood flow), 810nm (cognitive support, penetrates neural tissue), 830nm (joint and bone health, reaches connective tissue), 850nm (muscle recovery, penetrates deep muscle at 4-5cm), and 1060nm (deep tissue and metabolic support, penetrates 5-6cm+ to subcutaneous layer). Peak therapeutic irradiance occurs at 660nm and 850nm wavelengths, with 1060nm providing frontier deep-tissue penetration that most competitors do not offer.
Surface Spectrum
Visible red wavelengths (630-670nm) have the shortest penetration depth but maximum absorption by skin chromophores. Ideal for collagen synthesis, fine lines, and wound healing.
Target: Epidermis (0-1mm)
Primary Benefit
Surface Rejuvenation
Absorbed by cytochrome c oxidase at the skin surface. Stimulates fibroblast activity for collagen type I synthesis.
Clinical Note
Studies show 630nm increases fibroblast proliferation by 150-200% in vitro. Optimal for surface-level skin concerns.
Target: Upper Dermis (1-2mm)
Primary Benefit
Cellular Repair
Enhances cellular metabolism through mitochondrial stimulation. Promotes fibroblast activity and supports healthy cell turnover.
Clinical Note
650nm provides a bridge between surface and deeper red wavelengths. Optimal for overall skin vitality and cellular health.
Target: Dermis (2-3mm)
Primary Benefit
Collagen Production
Peak absorption wavelength for cytochrome c oxidase. Displaces nitric oxide, allowing oxygen to bind and ATP production to increase by up to 150%.
Clinical Note
The "gold standard" wavelength for skin health. Most studied in dermatological literature with consistent positive outcomes.
Target: Lower Dermis (2.5-3.5mm)
Primary Benefit
Circulation Enhancement
Enhances microcirculation and capillary blood flow. Supports nitric oxide release for vasodilation and improved nutrient delivery to skin cells.
Clinical Note
670nm bridges visible red and near-infrared spectrums. Particularly effective for circulation-related skin benefits.
Deep Tissue Spectrum
Near-infrared wavelengths (810-850nm) penetrate beyond the skin into muscle, connective tissue, and bone. Invisible to the eye but powerful for systemic recovery.
Target: Neural Tissue (2-4cm)
Primary Benefit
Cognitive Support
Penetrates the skull for transcranial photobiomodulation. Increases cerebral blood flow and mitochondrial function in neurons.
Clinical Note
Transcranial PBM at 810nm shows promise for cognitive enhancement and neurodegenerative conditions. Active research area.
Target: Connective Tissue (3-4cm)
Primary Benefit
Joint & Bone Health
Penetrates to joint capsules and bone surfaces. Reduces inflammatory markers in synovial fluid and may support osteoblast activity.
Clinical Note
Studies demonstrate significant reduction in inflammatory cytokines within joint spaces. Promising for osteoarthritis.
Target: Deep Muscle (4-5cm)
Primary Benefit
Muscle Recovery
Deep tissue penetration increases blood flow to muscle fibers. Accelerates clearance of metabolic waste and enhances nutrient delivery.
Clinical Note
850nm is the most studied NIR wavelength for muscle recovery. Multiple RCTs confirm 30-40% faster recovery from exercise-induced damage.
Frontier Spectrum
At 1060nm, we enter territory few competitors reach. This wavelength passes through the "water absorption window" to affect adipose tissue, deep organs, and structures beyond 5cm.
Target: Subcutaneous Layer (5-6cm+)
Primary Benefit
Deep Tissue & Metabolic Support
Bypasses water absorption peak at 970nm to penetrate deeply. May affect adipocyte metabolism and mitochondrial function in deep organs.
Clinical Note
Emerging research suggests 1060nm influences fat cell metabolism. The "frontier wavelength" with fewer competitors offering this spectrum.
