Red light therapy isn't one-size-fits-all. The wavelength — measured in nanometers (nm) — determines how deep the light travels and what it triggers inside your body. Here's what each frequency does.

630nm — Visible Red Collagen | Skin tone | Acne & inflammation |
630nm penetrates 1–2mm into the skin, targeting the epidermis and upper dermis. It activates fibroblasts — the cells that produce collagen and elastin — leading to firmer, smoother skin with regular use. It's also highly anti-inflammatory at the surface level, making it effective for active acne, redness, and rosacea. If your primary goal is visible skin improvement — tone, texture, glow — this is the wavelength driving those results.
• Collagen and elastin production
• Acne, rosacea, and surface inflammation
• Skin tone, texture, and brightness

660nm — Deep Red Deep repair | Wound healing | Muscle recovery |
At 660nm, light penetrates deeper — reaching 2–3mm into the dermis and beginning to affect muscle tissue. It drives ATP production more intensely than 630nm, giving cells significantly more energy to repair and rebuild. This is the wavelength behind red light therapy's use in sports medicine: it reduces muscle soreness, speeds recovery, and accelerates wound and scar healing. For skin, it works deeper in the collagen matrix than 630nm, addressing more significant aging and elasticity loss.
• Deep collagen remodeling and scar reduction
• Muscle repair and post-workout recovery
• Higher ATP output for accelerated healing

830nm — Near-Infrared Deep tissue | Sleep | Nervous system recovery |
830nm crosses into near-infrared — invisible to the eye but the most physiologically powerful wavelength. It penetrates 4–5cm, reaching muscle, joints, nerves, and bone. Clinically, it reduces systemic inflammation, lowers cortisol, and supports deeper sleep by regulating the nervous system. This is the wavelength most relevant to full-body wellness and recovery — not just what your skin looks like, but how your body functions day to day.
• Cortisol reduction and sleep quality
• Deep tissue and joint inflammation
• Nervous system regulation and recovery
Why Both Matter
The most effective devices pair visible red (630–660nm) with near-infrared (830nm) — skin-level renewal and deep physiological recovery in one session. That's the foundation of every VESA device.
