Why wavelength is the most important factor in LED therapy
Not all LED light is equal. The wavelength — measured in nanometers (nm) — determines how deeply the light penetrates your skin and what biological processes it activates. This is why a $30 LED mask from Amazon and a $380 CurrentBody mask are fundamentally different products, even if they both glow red.
The three wavelengths used in CurrentBody's most advanced devices are red (633nm), near-infrared (830nm), and deep near-infrared (1072nm). Each one does something distinct.
Red light (633nm): the collagen builder
Red light at 633nm penetrates the epidermis and upper dermis — roughly 1–2mm into the skin. At this depth, it's absorbed by fibroblasts, the cells responsible for producing collagen and elastin.
The result: increased collagen synthesis, improved skin texture, reduced fine lines, calmer redness and inflammation, and brighter overall complexion.
This is the most well-studied wavelength in skincare. If you see clinical data for LED therapy showing wrinkle reduction and skin quality improvement, it's almost always based on 633nm (or the closely related 630nm and 660nm variants). CurrentBody's clinical data shows a 30% reduction in wrinkles at this wavelength over 8 weeks.
Best for: Surface wrinkles, skin texture, redness, overall complexion improvement.
Near-infrared (830nm): the deep repair wavelength
Near-infrared at 830nm is invisible to the naked eye — your skin absorbs it but you can't see it glowing. It penetrates deeper than red light, reaching 3–5mm into the dermis and even into underlying tissue.
At this depth, it has more pronounced effects on cellular energy production (ATP synthesis), inflammation reduction, and tissue repair. It's the wavelength used in clinical and military settings for wound healing and injury recovery.
For skin, 830nm enhances the collagen-building effect of 633nm and adds a firming, tightening component that red light alone doesn't provide. The combination of 633nm + 830nm is the gold standard in anti-aging LED therapy.
Best for: Deeper wrinkles, skin firmness, inflammation, enhanced anti-aging results when combined with red light.
Deep near-infrared (1072nm): the new frontier
CurrentBody's Series 2 LED Face Mask introduced 1072nm — a wavelength exclusive to their devices and not found in competitors' masks. This is where things get genuinely interesting.
1072nm penetrates even deeper than 830nm, reaching beyond the dermis into the subcutaneous tissue. At this depth, it targets more pronounced signs of aging — the structural collagen that gives skin its volume and resilience, not just the surface-level collagen.
Think of 633nm as treating the surface of a wall, 830nm as treating the plaster beneath, and 1072nm as treating the brick underneath that. Each layer adds to the result.
Best for: More established signs of aging, pronounced wrinkles, volume loss, enhanced overall results for 40s and 50s skin.
Which device uses which wavelengths?
- CurrentBody LED Face Mask Series 2: 633nm + 830nm + 1072nm — the most comprehensive combination for anti-aging.
- CurrentBody LED Multi-Light Mask: 6 wavelengths including blue (415nm) for acne, yellow (590nm) for pigmentation, green (532nm) for dark circles, plus red and NIR — the most versatile option.
- CurrentBody LED Neck Mask Series 2: 633nm + 830nm — same core anti-aging wavelengths for the neck and décolletage.
The bottom line
If anti-aging is your goal, look for a device with both 633nm and 830nm as a minimum. The addition of 1072nm (exclusive to CurrentBody's Series 2) gives you the deepest collagen stimulation currently available in a home device. The more wavelengths working together, the more comprehensive the result.
