LED light therapy has its roots in NASA research and is now standard in dermatology clinics and professional skincare. The principle is simple: different wavelengths of light are absorbed by skin cells in different ways, and each one triggers a different response.
The wavelengths, briefly
Red light stimulates collagen production and supports skin renewal — the wavelength most backed by research for visible anti-ageing results. Near-infrared penetrates deeper than any visible wavelength, amplifying red light's effect on radiance and recovery. Blue light kills acne-causing bacteria, making it the go-to for blemish-prone skin. Green reduces pigmentation and evens tone. Yellow improves elasticity and firmness. Orange boosts radiance and tackles early signs of ageing. Cyan calms inflammation and soothes irritated skin. Purple combines red and blue to rejuvenate and strengthen.
Superglow covers all eight — seven colours plus near-infrared — across 11 modes. One device, every concern.
What actually matters for results
The biggest factor is consistency. A 10-minute session most days, built into an existing routine, will outperform an occasional longer one every time. It's also worth checking any device's wavelength range and LED count against published data — not just the headline number on the box.
Superglow uses 66 quad LEDs, for a total of 264 diodes plus 66 near-infrared emitters for even coverage across the whole face.
How to use it
Cleanse and dry your skin. Place the mask, choose your mode on the cordless remote, and wear for 10 minutes, it will automatically turn off. Follow with your usual serum or moisturiser. Use daily for the first two weeks, then 3–5 times a week to maintain results.
