A Clear, Simple Breakdown of Light Therapy for Skin
LED masks are quickly becoming a go-to in at-home skincare, but how do they actually work?
If you've seen glowing face masks all over your feed and wondered what they’re really doing beneath the surface—this guide breaks it down simply, without the jargon.
First, What Is an LED Mask?
An LED mask is a wearable skincare device that uses light therapy to treat skin concerns such as ageing, acne, sensitivity, and dullness.
LED stands for Light Emitting Diode. The mask uses low-level, non-invasive light energy to stimulate the skin—without heat, UV rays, or downtime. This clinically proven technology has been used in dermatology clinics for decades, and is now available in wearable, at-home devices.
How Does LED Light Therapy Work?
Different types of light reach different layers of the skin. These light wavelengths trigger natural processes in your skin—helping it repair, regenerate, and glow.
Red Light (around 630nm) – Collagen Support
Red light works just beneath the surface to stimulate collagen and elastin, which are essential for firm, youthful-looking skin.
Supports:
- Smoother skin texture
- Fine lines and wrinkles
- Elasticity and firmness
Blue Light (around 415nm) – Acne Defence
Blue light targets the bacteria that cause acne, while also helping to reduce oiliness and calm inflammation.
Supports:
- Fewer breakouts
- Less redness
- Clearer pores
Near-Infrared Light (around 830nm) – Deep Healing
This light penetrates deeper than red or blue to promote healing, reduce inflammation, and improve overall skin function.
Supports:
- Calming sensitive skin
- Recovery after treatments
- Long-term skin health
Why Do These Lights Matter?
These specific light wavelengths have been studied and used in clinical settings to improve a variety of skin conditions. Unlike lasers or harsh treatments, LED therapy is gentle, non-invasive, and safe for regular use at home.
With consistent use—just a few times per week—LED light therapy can support:
- Brighter, clearer skin
- Reduced breakouts
- Smoother fine lines
- A more balanced, resilient complexion
Enhancing Your Skincare Routine
An added benefit? LED therapy can actually help your skincare products work better.
When used before serums or moisturisers, the light helps stimulate circulation and opens the skin to absorb active ingredients more effectively—giving your products more power to do their job.
LED masks are more than just a trend. They’re a well-researched, proven tool to help you get more out of your skincare—with less guesswork.
Whether you're concerned about acne, scaring, ageing, redness or dullness, LED light therapy offers a customisable, effective way to care for your skin at home.
