Complete Guide to the 7 LED Mask Colours: What Each One Treats
Share
One of the most important advantages of the multi-spectrum LED face mask is its versatility: with one device you can treat different skin concerns simply by changing the colour. But to get the most out of it, it helps to understand what each wavelength actually does.
🔴 Red light — Anti-aging and regeneration (630–660 nm)
Red light is the spectrum with the most clinical evidence. It penetrates 1–6 mm into the dermis, where fibroblasts reside — the cells responsible for producing collagen and elastin.
Treats: wrinkles and expression lines, loss of firmness and elasticity, dull and dehydrated skin, superficial scars.
Use when: you want to fight visible ageing. It is the most recommended colour for people over 30.
Frequency: 4–5 times per week, 15–20 minutes.
🔵 Blue light — Anti-acne (415–430 nm)
Blue light acts directly on Cutibacterium acnes (formerly called Propionibacterium acnes), the anaerobic bacteria responsible for inflammatory acne. By activating the bacteria's porphyrins, it generates oxygen free radicals that destroy the bacterial cell membrane.
Treats: active acne (inflammatory comedones, pustules), excess sebum, acne-prone skin.
Use when: there are active breakouts or as prevention if you have oily skin.
Frequency: 2–3 times per week during active breakouts.
🟢 Green light — Tone unifier (520–530 nm)
Green light acts on melanocytes, inhibiting excess melanin production. It also has a calming effect on sensitised skin.
Treats: sun spots and pigmentation, uneven skin tone, erythema (non-inflammatory redness).
Use when: you have dark spots or uneven skin tone.
Frequency: 3–4 times per week.
🟡 Yellow light — Radiance and dark circles (570–590 nm)
Yellow light improves superficial microcirculation and cellular oxygenation. It is especially effective on the periorbicular area and on skin that shows signs of fatigue.
Treats: dull skin, vascular dark circles, diffuse redness, sensitive or reactive skin.
Use when: skin looks lifeless or shows accumulated tiredness.
Frequency: 3–4 times per week.
🟣 Purple light — Combined repair (red + blue)
Purple light simultaneously combines the effects of red and blue: it stimulates cell regeneration while fighting bacteria. Ideal for skin with active acne that also shows signs of ageing.
Treats: acne with marks and scars, skin that needs regeneration and bacterial control at the same time.
Use when: you have breakouts and want to treat the aftermath too (scars, post-acne marks).
🔷 Cyan light — Cellular activator (490–500 nm)
Cyan light stimulates overall cellular metabolism and improves the absorption of topical actives. It is used as "preparation" before applying serum or cream, enhancing their penetration.
Treats: skin lacking vitality, poor response to cosmetics, general revitalising effect.
Use when: you want to boost your skincare routine or skin needs an energy boost.
⚪ White light — Total rejuvenator (full spectrum)
White light acts on multiple photoreceptors simultaneously, accelerating cellular metabolism and enhancing the effects of the other colours. Many users use it at the end of sessions to maximise results.
Treats: overall ageing, when you want to work on several goals at once.
Frequency: 2–3 times per week as a complement to other colours.
