LED Light Therapy Colors Explained: What Each Wavelength Does？
Summary：LED light therapy has become one of the most popular non-invasive treatments in aesthetic clinics and spas. Different wavelengths (colors) of light penetrate the skin at varying depths, each triggering specific biological responses. From reducing acne to boosting collagen, knowing what each color does helps clinics create customized treatment plans and educate clients effectively.
How LED Light Therapy Works
LED (Light Emitting Diode) devices emit low-level light energy that stimulates the skin’s natural processes. Unlike lasers, LED does not damage the skin—it enhances cellular function. Each wavelength targets different skin concerns, making it a versatile addition to any treatment menu.
LED Light Therapy Colors and Their Benefits
| Color / Wavelength | Depth of Penetration | Key Benefits |
|---|---|---|
| Red (620–750 nm) | Medium depth | Boosts collagen, reduces wrinkles, improves circulation |
| Blue (405–470 nm) | Surface level | Kills acne-causing bacteria, reduces oil production |
| Green (520–560 nm) | Shallow to medium | Targets hyperpigmentation, evens skin tone, calms redness |
| Yellow (570–590 nm) | Medium depth | Reduces inflammation, improves lymphatic flow, brightens skin |
| Near-Infrared (700–1200 nm) | Deepest | Promotes healing, reduces pain, accelerates tissue repair |
Combining Colors for Enhanced Results
Many professional LED devices allow multi-wavelength treatments, where different colors are combined for synergistic benefits:
-
Red + Blue: Anti-aging + acne control.
-
Red + Near-Infrared: Deep collagen repair and healing.
Green + Yellow: Brightening and calming for sensitive skin.
Conclusion
LED light therapy is a powerful yet gentle tool for aesthetic clinics, with each color addressing specific skin concerns. By tailoring treatments based on client needs—whether it’s acne, pigmentation, or aging—you can deliver personalized, effective, and non-invasive results.
