LED light therapy isn't just about different colors—it's about the specific wavelengths of light measured in nanometers (nm). Each wavelength penetrates the skin at a different depth and targets different concerns, from acne and inflammation to wrinkles and skin rejuvenation.
Understanding wavelengths can help you choose the right treatment and get better results from your skincare devices.
| Wavelength | Color | Primary Benefits | Best For |
|---|---|---|---|
| 415–465nm | Blue | Helps target acne-causing bacteria, reduces breakouts | Acne-prone skin |
| 520–530nm | Green | Helps improve uneven skin tone and pigmentation | Hyperpigmentation |
| 580–595nm | Yellow | Helps calm redness and soothe sensitive skin | Rosacea, redness |
| 620–660nm | Red | Supports collagen production and skin rejuvenation | Fine lines, wrinkles |
| 830–850nm | Near Infrared | Penetrates deeper to support healing and recovery | Anti-aging, skin repair |
| 1072nm | Deep Infrared | Reaches deeper tissue layers for advanced rejuvenation | Mature skin, deep wrinkles |
Research and dermatology experts consistently identify red light (620–660nm), blue light (450–495nm), and near-infrared light (760–1400nm) as the wavelengths with the strongest evidence for skincare applications.
Blue light works near the skin's surface and helps reduce acne-causing bacteria while calming inflammation.
Blue light therapy is widely used for acne treatment because of its antibacterial effects and ability to reduce inflammation.
Yellow light works within the upper layers of the skin and is often used to soothe irritation and reduce visible redness.
While yellow light has less clinical research than red and blue light, it is commonly used for soothing and calming benefits.
630nm red light penetrates deeper than blue or yellow wavelengths and stimulates cellular activity associated with collagen production.
Red light therapy is one of the most studied wavelengths for anti-aging and skin rejuvenation.
Unlike visible light, near-infrared light is invisible to the eye. It penetrates deeper into tissue than red light and supports cellular recovery.
Near-infrared wavelengths between 830nm and 850nm are frequently included in professional-grade LED devices because of their deeper penetration capabilities.
1072nm penetrates deeper than traditional near-infrared wavelengths, reaching deeper tissue layers beneath the skin.
Many next-generation LED technologies are beginning to incorporate deeper infrared wavelengths alongside traditional red and near-infrared light to create more comprehensive treatment protocols.
Skin concerns rarely exist in isolation. That's why many advanced LED devices combine multiple wavelengths in a single treatment.
For example:
By combining wavelengths, you can address multiple skin concerns simultaneously while maximizing treatment results.
The latest generation of ZAQ LED devices combines clinically recognized wavelengths including:
Designed for both skincare professionals and home users, these technologies work together to support clearer, healthier, and more youthful-looking skin.
