The Science Behind Your Skin's Renewal
Why topical skincare alone will never be enough.
Collagen, elastin, and the fibroblasts that produce them all live in the dermis — the layer beneath the epidermis. No serum, cream, or retinol can reach that far. They work on the surface. LED light therapy works beyond it, delivering targeted photons directly to the cells responsible for your skin's structure and renewal. That's not marketing. That's physics.
The Evidence
What the published research shows.
These numbers are from peer-reviewed clinical studies on red, near-infrared, and blue light therapy — not claims about this specific device.
630nm · Red Light
+31%
Increase in intradermal collagen density over 12 weeks of red and near-infrared light treatment.
Wunsch & Matuschka, Photomed Laser Surg, 2014;32(2):93–100
850nm · Near-Infrared
4mm
Depth of light penetration into biological tissue at near-infrared wavelengths, reaching the subcutaneous layer.
Ash et al., Lasers Med Sci, 2017;32(8):1909–1918
460nm · Blue Light
77%
Of patients showed clinical improvement in acne after 5 weeks of blue light therapy sessions.
Kawada et al., J Dermatol Sci, 2002;30(2):129–135
Three wavelengths. Three targets.
'nm' stands for nanometer — the unit used to measure wavelengths of light. Different wavelengths penetrate your skin to different depths, each targeting specific concerns.
-
Red Light — 630nm
The most clinically studied wavelength for anti-aging. 630nm light penetrates the skin's surface to boost cellular energy production (ATP), accelerating natural repair. The result: reduced fine lines, improved skin tone, and a visible reduction in dark spots with consistent use.
-
Near-Infrared — 850nm
Invisible to the eye but powerful beneath the surface. 850nm near-infrared light penetrates deeper than red light to stimulate collagen synthesis and fibroblast activity — the cellular processes responsible for skin firmness and elasticity. This is the wavelength that works at the structural level.
-
Blue Light — 460nm
460nm blue light targets and destroys acne-causing bacteria (P. acnes) on the skin's surface. It works by activating porphyrins within the bacteria cells, creating a reaction that eliminates them without harsh chemicals or UV exposure — leaving skin clearer and calmer over time.
The Three Wavelengths
How light reaches the skin.
A brief explanation of what each wavelength does — drawn from forty years of dermatological research.
Depth of Penetration · Skin Cross-Section
What Each One Does
630nm · Red
The most-studied wavelength in the category. Used in dermatology since the 1990s for collagen support and tissue repair.
850nm · Near-infrared
Penetrates deeper than visible light. Reaches subcutaneous tissue. Studied for circulation, recovery, and mitochondrial activity.
460nm · Blue
Acts at the surface. Used clinically for breakout management and skin tone refinement at the epidermal layer.
