An Expert Look at the Science Behind Skincare Light Treatments
LED (Light Emitting Diode) therapy has steadily gained popularity as a non-invasive, science-backed solution for improving skin health. But how does it actually work—and is it truly effective? This article explores the underlying principles, applications, and the benefits of various light wavelengths, while also comparing Kingdo’s innovative LED devices with other products on the market.

1. How LED Light Therapy Works
LED light therapy uses specific wavelengths of light to penetrate the skin at various depths, stimulating natural cellular processes. Originally developed by NASA for wound healing in space, it has since become a trusted tool in dermatology.
Light energy absorbed by skin cells promotes ATP (adenosine triphosphate) production, boosting cellular turnover and collagen synthesis. The result? Enhanced skin regeneration, reduced inflammation, and improved tone and texture.
“LEDs don't cause burns compared to other anti-aging treatments such as chemical peels, dermabrasion, and laser therapy.”
2. Common Applications of Light Therapy in Skincare
LED light therapy is used to address a wide range of skin concerns:
Acne: Blue light eliminates acne-causing bacteria.
Wrinkles & Fine Lines: Red light promotes collagen and elastin production.
Hyperpigmentation: Yellow and green light can brighten the skin and reduce dark spots.
Sensitivity and Redness: Light therapy reduces inflammation and strengthens the skin barrier.
Its non-invasive nature makes it ideal for consistent at-home use, with results that build over time.
3. Types of Light Used in Therapy
Light Type | Wavelength | Target | Main Benefit |
|---|---|---|---|
Blue | 405–470 nm | Surface | Anti-bacterial, acne prevention |
Red | 620–750 nm | Mid-layer | Collagen production, anti-aging |
Near-infrared | 750–900 nm | Deep layers | Wound healing, inflammation reduction |
Green | ~520 nm | Melanin clusters | Evens skin tone, brightens dullness |
Yellow | ~590 nm | Circulation | Reduces redness, improves glow |
Each color offers unique benefits, and combining them can enhance outcomes in multi-concern treatment.
