LED light therapy colour benefits: Each wavelength explained

If you’re a skincare enthusiast, there’s a good chance you’ve heard of LED light therapy. Once reserved only for professional use behind the doors of skincare clinics, this high-tech therapy is now accessible from the comfort and convenience of your home thanks to the CurrentBody Series 3 LED Mask.

Red light therapy might be the one you know best, but other colours are available. Each wavelength offers its own therapeutic beauty benefits. Read on to find out how they work, what they do, and how they can support your skincare goals.

What is LED light therapy?

LED (light emitting diode) therapy uses light to penetrate the skin at different depths depending on the wavelength. Research suggests that as this light passes through the skin, it’s absorbed by cells, supporting the skin’s natural processes, for visibly healthier, more youthful-looking skin.

Different wavelengths can be used during LED light therapy, each corresponding to a different visible colour.

What are the benefits of each LED light therapy colour?

The most recognised and widely used form of LED therapy, red light therapy can include red, near-infrared (NIR) and deep near-infrared wavelengths, popular due to their association with anti-ageing and overall skin-boosting effects.

Red light (633nm) has been shown to boost collagen and elastin production to help reduce the appearance of lines and wrinkles, pigmentation and redness. Meanwhile, near-infrared (830nm) and deep near-infrared (1072nm) light travel deeper into the skin to support skin renewal for advanced, visible firming, plumping and smoothing.

Blue light therapy benefits

The most superficial of all wavelengths, blue (415nm) light is associated with targeting the bacteria that contribute to spots and blemishes, supporting clearer-looking skin and helping prevent new blemishes from forming.

This clarifying wavelength is also linked to reducing oiliness, helping to limit shine and supporting more balanced-looking skin over time.

Green light therapy benefits

Targeting the cells responsible for producing your skin’s natural pigment, green (532nm) light is known for helping improve the appearance of uneven skin tone, supporting a more balanced and even-looking complexion over time.

This calming wavelength helps to visibly soothe skin, ideal for those who are prone to facial redness, or looking to complement their clarifying blue light sessions.

Green light’s calming qualities may not just be skin-deep. The wavelength has also been explored for its links to relaxation and mood, giving ‘beauty sleep’ a new meaning. So while your skin gets its glow-up, consider your session a moment of calm to unwind.

Yellow light therapy benefits

Penetrating the skin at a greater depth than blue or green light, yet shallower than red light, yellow (590nm) light targets the dermal layer of skin, where it is absorbed by cells. This supports the skin’s natural functions, helping to calm visible redness and even out skin tone for clearer, brighter skin.

By energising cells in this way, yellow light is also linked to visibly reducing puffiness, supporting a refreshed, revitalised-looking appearance.
