LED Devices for Acne: Science Behind Blue & Red Light
Summary:
LED light therapy has become one of the most sought-after non-invasive treatments for acne-prone skin. Using precise wavelengths of blue and red light, these devices reduce breakouts, calm inflammation, and improve overall skin clarity without harsh chemicals or downtime.
How LED Light Therapy Works for Acne
LED (Light Emitting Diode) therapy delivers low-level wavelengths of light into the skin’s surface layers. Each color targets specific cellular responses that help restore skin balance.
| Light Type | Wavelength Range | Key Action |
|---|---|---|
| Blue Light | 415–470 nm | Kills acne-causing bacteria (*Propionibacterium acnes*) and helps control sebum production. |
| Red Light | 620–660 nm | Reduces inflammation, accelerates healing, and minimizes post-acne marks. |
| Near-Infrared | 800–900 nm | Enhances blood circulation and supports tissue repair for long-term skin health. |
