Browse LED masks online, and you'll find a rainbow of options: red, blue, green, yellow, purple, cyan and more. With so many LED therapy mask colours on offer, it's natural to wonder how many you really need.
The short answer? Probably fewer than you think. Let's unpick four of the most common myths about light therapy colours and look at what the research actually supports.
Myth 1: More Colours Mean More Benefits
Adding colours to a mask is easy. Proving that each one earns its place is much harder. Many multi-colour devices include wavelengths with limited evidence, or several modes with different names that deliver broadly similar light.
That can make a spec sheet look impressive without making treatment any more effective. What matters is whether each wavelength reaches the right layer of skin, at the right dose, with research to back it up.
Myth 2: Each Colour Fixes a Specific Skin Concern
Colour charts often promise neat matches: green for pigmentation, yellow for redness, blue for breakouts. The reality is more nuanced.
Blue light does have antibacterial effects that can help blemish-prone skin. But clinical research shows that blue-violet light drives more pigmentation than longer wavelengths, particularly in darker skin, so it's best used with care if you're prone to melasma.
Green light at 505nm reduced melanin in a small 2025 study, but many masks use a different green wavelength. Yellow light can ease the redness linked to melasma, yet a 2025 pilot found it only worked preventively. In the same study, 830nm near-infrared both prevented and improved existing redness and pigmentation.
Myth 3: If It Works in the Lab, It Works on Your Face
Plenty of colour claims are built on cell studies. A 2026 study, for example, found yellow light was the strongest inhibitor of melanin production in mouse cells.
But those cells grew in a single flat layer, with no skin for light to travel through, so every wavelength reached them equally. Yellow was also the only wavelength the researchers pulsed, which may have given it an edge.
On a real face, yellow and green give up most of their energy near the skin surface. Red and near-infrared on the other hand reach the basal layer, where pigment cells sit, and the dermis beneath it, where collagen is made.
Myth 4: The Longer the Wavelength, the Better
"Deep near-infrared" at 1,072nm is increasingly promoted as the next step up. Longer wavelengths are absorbed less by melanin, but water absorption climbs steeply above 1,000nm, so more energy turns into heat rather than a useful biological signal.
A 2025 study measuring light through the head even found that 810nm reached deeper in practice than 980nm or 1,064nm. We compare these options in more detail in our article on pulsed LED versus laser diodes and 1072nm.
So Which Colours Should You Prioritise?
For rejuvenation and tone, red (around 630 to 660nm) and near-infrared (around 830 to 850nm) have the strongest evidence of any colours. A 2025 randomised, sham-controlled trial of a home-use mask combining red and near-infrared light reported an 69% improvement rate in crow's feet, with 87% of individuals responding positively to the treatment.
And the science around red and near infrared is not just about anti-aging. Research indicates these are currently the most evidence-based options for a brightening or depigmentation strategy.
From an early 2016 study we know that red light at 660nm reduces melanin synthesis by downregulating tyrosinase, one of the key enzymes involved in melanin production in melanocytes.
And red (633nm) and near-infrared (830nm) combined reduced melasma intensity in one of the few studies conducted specifically on darker skin, Fitzpatrick phototypes V and VI, with no adverse effects during the study period — a valuable citation given how under-studied deeper skin tones are.
Even when used on patients who had not responded to previous treatments, an 8 week programme of pulsed near infrared (940nm) LED, preceded by microdermal abrasion, proved a successful strategy for clearing dermal melasma. And, even more encouraging, researchers reported that NIR may pre-condition the skin, helping it to build a resistance to UV exposure.
More recent studies allude to how NIR works to suppress melanin, identifying a control protein in the cell, known as a transcription factor, which acts as an internal control switch that dials the pigment machinery down.
And a 2025 pilot found NIR at 830nm both preconditioned skin against UVB and repaired existing post-inflammatory erythema and hyperpigmentation.
Customisation That Actually Helps
Having options is useful, but only the right ones.
Red light therapy is not one-size-fits-all: melanin behaves differently across skin tones, and pigmentation is the one area where all light must be used carefully since visible light, particularly blue light, can itself provoke pigment, most of all in deeper skin tones. Regardless of what the science says, individuals may respond to light differently, and for melanin-rich skin, particular caution should be used with red light therapy to avoid delivering too much energy to the surface of the skin, which could trigger melanogenesis and pigment formation.
Red light is a shorter wavelength that travels just a few millimeters into skin and is largely absorbed by melanin and haemoglobin. As a longer wavelength, not absorbed by melanin, near infrared bypasses the melanin-rich epidermis to target the deeper layers and may present a safer option for melanin-rich skin looking to treat melasma.
The ability to isolate red or near-infrared lets you tailor treatment according to your issues and skin tone. That's the thinking behind the AURA LED Light Therapy Face Mask. It uses red at 630nm and near-infrared at 830nm across three modes: red plus near-infrared, red only, or near-infrared only.
SMART Dosing automatically extends the session when you isolate a wavelength, keeping each treatment within its intended dose. And rather than shining continuously, the light is delivered through Maysama's Intelligent Micro-pulsing Technology™.
Red and Near Infrared - is all you need
Whilst emerging science around the beneficial effects of the broader visible and invisible light spectrum is interesting, the nuances that separate these wavelengths are subtle even for people in the field, and without clear guidance, it's easy to use a mask sub-optimally or choose combinations that work against your goal.
In Maysama’s view, most people are best served by a few well-designed, evidence-led modes, rather than being handed a long menu of wavelengths and left to work out the science themselves when red and near infrared already delivers the core benefits.
So the message is clear - whether you are looking for anti-aging, reducing redness and pigmentation or looking for a solar protection strategy, red and near infrared light have you covered, with the strongest evidence base of all LED wavelengths.
For us, meaningful customisation means being able to isolate the wavelengths with the strongest evidence behind them.
Pulsing and Pigmentation
If pigmentation is the main concern you want to address, wavelength is not the only consideration; how the light is delivered matters too.
Pulsed delivery switches the light on and off in rapid cycles, which allows the dose to be controlled more precisely than with a continuous beam. During each "off" interval, known as the quench period, the skin has a chance to cool, so light energy does not accumulate as heat.
This matters because heat is a recognized trigger for melasma. In the 2018 melasma study described above, which used pulsed near-infrared light, the author noted that these longer dark intervals may play a key role, partly by reducing the build-up of heat in the tissue that could increase melanocyte activity.
Extending Treatment Beyond the Face
The neck and décolletage are often overlooked, despite showing signs of ageing just as readily as the face. The AURA LED Light Therapy Neck2Dec offers the same three modes and micro-pulsing, with 155 dual LEDs across an extra-wide neck band and chest area.
Cordless and made from flexible, 3D contoured silicone, it's designed to sit close to the skin, helping light spread evenly across curves that flat devices can struggle to reach.
Why Fit Matters as Much as Colour
Choosing the right wavelengths is only half the story. Light also needs to reach your skin evenly, and that depends heavily on the shape of the device.
A mask that conforms to your face keeps every area at a consistent distance from the LEDs, so the cheeks, jawline and forehead all receive a similar dose. A flat device held in front of the face delivers light less evenly across its natural contours. Comfort plays a part too, because a mask that's pleasant to wear is one you'll keep using.
A Quick Checklist Before You Buy
Before choosing an LED mask, run through these points:
- Does it offer red at around 630 to 660nm and near-infrared at around 830 to 850nm?
- Can you use each wavelength on its own if your skin needs it?
- Is the dose controlled for you, with clear session times?
- Does it sit close to the skin, with LEDs spread evenly across the face?
- Is it comfortable and cordless enough to use three to five times a week?
If a device ticks these boxes, the number of colours on the box matters far less.
Final Thoughts
When it comes to LED therapy mask colours, focus beats variety. Red and near-infrared light remain the best-evidenced choices, while other colours play narrower roles that are often overstated.
Look for proven wavelengths, controlled delivery and a design you'll enjoy wearing, because consistency is what delivers results. Discover Maysama's range of beauty devices to find the right fit for your skin.
