Eczema isn’t just a skin problem.

It’s a cellular one.

Here’s exactly what red light does about it — and why nothing you’ve put on your skin ever could.

Why Nothing Has Worked...

You’ve tried the creams...

The steroids. The elimination diets. The GP appointments that ended with the same prescription you already had. The expensive moisturisers. The antihistamines. Maybe immunosuppressants. Maybe Chinese medicine. Maybe sunbeds, because at least those actually did something.

None of it fixed it.

Not because you didn’t try hard enough. Not because you got unlucky. But because every single one of those things — including the ones prescribed by doctors — was working on the surface of a problem that lives underneath it.

Eczema is not a problem of dry skin or the wrong moisturiser. It is a problem of broken cellular function: a faulty skin barrier, overactive inflammatory signals, hypersensitive nerve endings, and — for many people who have used steroids for years — skin that has been structurally thinned by the very treatment meant to help it.

No cream can reach that. No pill addresses all four. But light can.

Here is what is actually happening in your skin — and what red light therapy does about each of it.

01 — The Itch Signal

The itch is not in your skin. It’s in your nerves. Here’s why that changes everything.

If you’ve ever scratched until you bled — in your sleep, without even meaning to — you already know that willpower is not the problem. The problem is that the signal telling your body to scratch is firing constantly, at a volume that cannot be ignored.

In eczema skin, the nerve endings just beneath the surface — specifically a type called C-fibres — become chronically sensitised. They fire the itch signal far more easily than they should, in response to things as minor as fabric, cool air, or a change in temperature. The scratch reflex that follows is not a conscious decision. It is a neurological response to an alarm that will not stop going off.

This is why every topical treatment only manages eczema rather than resolving it. Creams and steroids address the skin surface. They cannot reach the nerve endings underneath. The alarm keeps firing.

Cream won't stop the itch, because the nerve endings responsible sit deeper below the skin.

What red and near-infrared light does:


Wavelengths at 830nm and 850nm penetrate beneath the skin surface to the dermal layer where these hypersensitive nerve endings live. At the cellular level, the light reduces the release of neuropeptides — the chemical signals that trigger the itch-scratch reflex. It does not numb the nerves. It calms the sensitivity that has been driving the alarm in the first place.


In clinical trials, this mechanism produced results that creams simply cannot: patients reported the itch itself reducing, not just their skin looking better. When the itch reduces, the scratch cycle breaks. When the scratch cycle breaks, the skin gets the chance to actually heal.


In a 112-patient trial published in the Japanese Journal of Clinical Dermatology, 79% of eczema patients reported that itching was reduced following red light therapy at 830nm.

02 — The Broken Barrier

Why your skin lets everything in and holds nothing back — and how red light helps rebuild it from below.

Healthy skin has a barrier. Think of it as a tightly packed wall of cells, held together by natural fats, that keeps moisture in and allergens, bacteria, and irritants out. In eczema skin, this wall is structurally compromised — the cells are spaced too far apart and the fats between them are insufficient.

The result is a skin that cannot hold moisture, so it dries out relentlessly. A skin that cannot keep things out, so tap water stings, central heating inflames, and certain fabrics trigger a flare within minutes. A skin that heals slowly, because the cells responsible for repair — called fibroblasts — are operating in a constant state of inflammatory overload.

This is why winter in the UK is so particularly brutal for eczema. The combination of cold air outside and dry, heated air indoors strips the already-compromised barrier of what little moisture it can hold. The same reason a foreign holiday can feel like a reset — the humidity, the warmth, the natural light — is the same reason coming home feels like starting from scratch.

A cream applied to the surface can temporarily add moisture. It cannot rebuild the barrier structure that has been broken.

What red and near-infrared light does:


Red light at 660nm stimulates fibroblast activity — the cells responsible for producing collagen and repairing the structural components of the skin. Near-infrared wavelengths at 830–850nm penetrate deeper, reducing the pro-inflammatory cytokines that keep the barrier in a state of chronic inflammation.


The result is not temporary surface moisture. It is accelerated structural repair: the skin gradually rebuilds its own barrier, becoming better at retaining moisture and excluding triggers. For people who have experienced eczema skin all their lives, this is a qualitative shift that feels materially different from anything a topical product can achieve.



In a Kyoto University clinical trial of 81 patients, red light therapy at 660nm produced a 47% reduction in eczema severity scores (SCORAD) and significantly decreased the leathery, thickened skin patches associated with chronic scratching.

"I have been suffering from eczema for the last 3 years and have been in TSW for around 2.7 years. My skin was stagnant — no healing or progress for over a year. Just red, dry, cracked, flaking and oozing. At the start, the panel did end up making my skin flake a lot temporarily for around a week, but underneath came soft skin, the redness had reduced significantly, I had a lot more elasticity. Several weeks later my skin had become a lot stronger. At one point I couldn’t tolerate wind hitting my skin. Now I can use cleansers and all sorts."

03 — The Damage Steroids Leave Behind

If you’ve used steroid creams for months or years, your skin has a second problem. This one almost no one talks about.

Topical steroids work. In the short term, they reduce inflammation, calm a flare, and give the skin a temporary window of relief. No one disputes this. But there is a side effect that most GPs mention only in passing, and that most patients are never properly warned about.

Long-term use of topical corticosteroids suppresses the activity of fibroblasts — the cells whose job it is to produce collagen. Collagen is not just about looking younger. In the skin, it is the structural scaffolding: it gives skin its thickness, its tensile strength, its ability to heal. When fibroblast activity is consistently suppressed, the skin gradually thins. It becomes more fragile, more easily damaged, slower to heal, and more prone to visible surface changes — including broken capillaries, easy bruising, and a papery texture that does not recover between flares.

This is a documented dermatological process called corticosteroid-induced skin atrophy. And it means that many long-term eczema sufferers are not just dealing with the condition itself. They are dealing with skin that has been structurally weakened by years of the treatment.


An illustrative diagram showing the fibroblast mechanism

What red and near-infrared light does — and why this matters most:


Red light at 630–660nm penetrates to the dermal layer and directly reactivates fibroblast activity. These fibroblasts respond by producing new collagen and elastin — rebuilding the structural components of the dermis that have been depleted. This is not a surface effect. It is the same cellular mechanism used in clinical skin rejuvenation and post-procedure recovery, now applied to skin that has been thinned by years of steroid use.


The mitochondria in each fibroblast absorb the red light through a protein called cytochrome c oxidase. This triggers increased ATP production — adenosine triphosphate, the molecule that powers every cellular repair process. For steroid-damaged skin, this is the equivalent of refuelling a repair system that has been running on empty. New collagen is laid down. Skin gradually becomes thicker, more elastic, more resilient, and better able to heal between flares.



This is the part of the mechanism that is often missed: it is not only anti-inflammatory, it is structurally restorative. For someone whose skin has been thinned and weakened by long-term steroid use, this distinction matters enormously.

In plain terms:


Steroids borrow against your skin’s structure. Red light helps pay it back.

04 — Why It Has To Be Clinical Grade

If you’ve tried a home LED device and seen nothing, this is why. The mechanism only activates above a specific power threshold — and most consumer devices never reach it.

Red light therapy works. This is not a fringe claim. It is backed by over 10,000 peer-reviewed clinical studies, and the NHS already prescribes UV-based light therapy for eczema (the waiting list, depending on where you are in the UK, can be well over a year).

But here is the thing that the industry almost never tells you: the results those clinical studies demonstrate depend entirely on the device being used. Specifically, they depend on something called irradiance — the power output of the light, measured in milliwatts per square centimetre (mW/cm²).

The studies that show 79% reductions in itching, 47% improvements in severity scores, and meaningful barrier repair — all of them used devices operating at a minimum of 50 mW/cm² for surface effects, and 100 mW/cm² or above for deep tissue benefit. Below this threshold, the cellular mechanism does not activate. You are not getting a weaker version of the result. You are getting nothing.

The LED masks sold in pharmacies and on beauty websites typically output between 5 and 15 mW/cm². They are not under-delivering on the promise. They are operating at a power level where the therapeutic mechanism cannot begin.

The Solis specification:


• ~180 mW/cm² at 6 inchesclinical grade, deep tissue penetration


• 5 wavelengths630nm, 660nm, 810nm, 830nm, 850nm — weighted to match the most studied frequencies in published eczema research


• FDA/CE manufacturing standardssafe for use on broken, sensitised, and TSW-affected skin


• Anti-EMF materials0 EMF at 3+ inches: important for a community that is acutely aware of environmental triggers


• Personalised eczema protocol includedspecific guidance for your condition, not a generic leaflet

The reason your previous experience with a home device produced nothing is not that red light therapy does not work. It is that the device you used had nowhere near the power to trigger the mechanism. This is the distinction that matters.

"Finally … something that is easing my eczema! I started with a smaller solo panel to try it. So a month later I invested in the full panel. I started with a smaller solo panel to try it — but found that whilst I could feel the benefits, it took a long time to do all parts of my body. So a month later I invested in the full panel. I would heartily recommend it — and the customer service at Solis has been second to none."

"I decided to give RLT a try. It was a big investment but it paid off. At the start the panel did end up making my skin flake a lot temporarily for around a week but underneath came soft skin, the redness had reduced significantly, I had a lot more elasticity and instead of going through 500ml tubs of moisturiser per week I noticed my skin was self-moisturising. Several weeks later I could notice my skin had become a lot stronger."

Red Light for Eczema FAQs

Will it work for my specific type of eczema?

The mechanisms described on this page — nerve calming, barrier repair, collagen restoration, and inflammation reduction — are not specific to one type of eczema. They address the underlying cellular processes that drive atopic dermatitis, contact dermatitis, dyshidrotic eczema (hands and feet), and TSW-related inflammation. The clinical studies cited used patients with atopic dermatitis specifically. The Solis panel has been used by sufferers across all eczema subtypes and severities. Your personalised protocol will be tailored to your specific pattern.

My skin is very sensitive — is it safe to use during a flare or on broken skin?

Red light therapy is non-invasive — nothing is applied to the skin surface. For highly sensitised or broken skin, including active TSW, start at a greater distance (30–40cm rather than 20cm) and reduce session time to 5 minutes until the skin builds tolerance. Many TSW sufferers have used the panel during active withdrawal with positive results (see M.H.’s review above). Your personalised protocol will include specific guidance for sensitised skin. The Solis panel is built to FDA and CE manufacturing standards, with zero EMF at 3+ inches.

I tried a red light device before and it did nothing. Why will this be different?

Almost certainly because the device you used was operating below the therapeutic activation threshold. Consumer LED masks and low-powered home devices typically output 5–15 mW/cm². The clinical studies that demonstrate the results described on this page used devices at 50–100 mW/cm² minimum. The Solis panel delivers ~180 mW/cm² at 6 inches — well above the clinical threshold. The mechanism could not activate in your previous device. At Solis’s irradiance level, it can.

How quickly will I see results?

Be honest with yourself here: eczema that has taken years or decades to develop will not reverse in a week. What most people notice first, within the first two to three weeks of consistent use, is a reduction in itching — specifically at night, which is where the impact on quality of life is often most felt. Skin barrier improvement and structural collagen repair take longer because you are rebuilding at a cellular level. Some users experience an initial shedding of damaged surface skin in week one — this is a sign that the healing process has begun, not a problem. Results compound with consistency. Three sessions per week, sustained over 6–8 weeks, is the recommended baseline.

Is this just another thing I’ll waste money on?

We understand why you’d ask that. If you’ve spent years cycling through creams, prescriptions, and supplements, this is the most rational question on this page. What makes Solis different is not the marketing claim. It is the mechanism — the cellular level at which the treatment operates — and the irradiance specification that means the mechanism can actually activate. It is also the honesty: results take time and consistency. We tell you this upfront because we would rather set a realistic expectation than make a promise that fails you. Your personalised protocol is included free with every purchase and comes from a team that has worked with thousands of eczema customers.
