Red Light Therapy for Skin Conditions: Eczema, Psoriasis, Rosacea and Healthy Ageing

Skin Health — Aim Health Hoylake

Healing skin from the inside out

Red and near-infrared light therapy works at a cellular level to reduce inflammation, repair the skin barrier, boost collagen and change how your skin behaves — not just how it looks.

Skin conditions like eczema, psoriasis and rosacea aren’t primarily surface problems. They’re driven by inflammation, immune dysregulation and cellular dysfunction happening deep in the tissue. Red light therapy works from the inside out — stimulating the mitochondria inside your skin cells to produce more energy, accelerating natural repair, reducing inflammation and boosting collagen production. It’s skin healing at the level where skin health actually begins.

Why surface treatments only go so far

Most of us have been taught to think about skin health from the outside in. The right cleanser, the right moisturiser, the right serum. And while what you put on your skin matters, there’s a dimension of skin health that gets far less attention — what’s happening inside your cells.

Skin conditions like eczema, psoriasis and rosacea aren’t primarily surface problems. They’re driven by inflammation, immune dysregulation and cellular dysfunction happening deep in the tissue. And skin ageing — the loss of collagen, elasticity and tone that comes with time — is a cellular process long before it becomes a visible one.

Red light therapy works at that cellular level. Rather than treating the surface of the skin, it stimulates the mitochondria inside your skin cells to produce more energy, accelerating natural repair, reducing inflammation and supporting collagen production.

How red light therapy works on skin

Red light therapy — also called photobiomodulation — uses specific wavelengths of red and near-infrared light to reach the skin at a cellular level. The light is absorbed by the mitochondria inside your skin cells and triggers a cascade of natural repair and regeneration processes.

What happens at a cellular level during a session

Inflammation reducesThe light calms the inflammatory signals that drive eczema and psoriasis flare-ups, reducing pro-inflammatory cytokine activity systemically.

Skin barrier function improvesSupports the skin’s ability to protect itself and retain moisture — the barrier dysfunction that makes eczema skin so reactive begins to repair.

Collagen production is stimulatedStudies show collagen increases of 138–211% with regular therapy, supporting skin structure, texture and resilience.

Circulation in skin tissue improvesMore oxygen and nutrients are delivered to where they’re needed, supporting healthy cell turnover and repair.

Oxidative stress reducesA key driver of both inflammatory skin conditions and skin ageing is brought under control at the cellular level.

The result is skin that is better equipped to manage its own inflammation — rather than being constantly overwhelmed by it.

What our clients tell us

Across the clients we see at Aim Health for skin conditions, certain things come up again and again. The itching reduces — often noticeably, and often before anything else changes visibly. The redness calms. Flare-ups, when they come, tend to be less severe than before and settle more quickly.

What many clients discover is a pattern that works for them: more frequent sessions during a flare to calm things down, then regular maintenance sessions to keep the skin stable between flares. Rather than reacting to their skin, they start to feel ahead of it.

Red light therapy for eczema — the evidence

The clinical evidence for red light therapy in eczema is growing and consistently positive. A 2013 study published in the Journal of Drugs in Dermatology found significant reductions in eczema severity after four weeks of red light treatment. A 2024 study confirmed that red light exposure reduced the inflammatory processes in eczema and decreased the pro-inflammatory cytokine activity that drives flare-ups. Researchers following 81 patients over nearly a year documented consistent improvements in symptoms with regular sessions.

For eczema specifically, the advantage of whole body red light therapy is the coverage. Eczema rarely stays in one place — it appears across arms, legs, the neck, the face and the torso. A full-body session at Aim Health treats every affected area simultaneously, addressing both the local symptoms and the systemic inflammation that underlies them.

Red light therapy for psoriasis

Psoriasis is an autoimmune condition in which the immune system accelerates the skin cell cycle, causing the thick, scaly, inflamed patches that characterise the condition. The evidence for red light therapy in psoriasis is compelling.

A study published in the Journal of the American Academy of Dermatology found that red light therapy improved psoriasis symptoms — reducing itching, scaling and redness — after just four weeks. Several trials have reported 60–100% clearance rates of treatment-resistant psoriasis plaques, with researchers noting that patient satisfaction was universally high. A 2025 study confirmed that red light treatment decreased skin thickness and the abnormally rapid cell replication that causes psoriatic plaques to form.

For people with psoriasis covering large areas of the body, whole body red light therapy offers comprehensive coverage in a single session — addressing both the visible plaques and the underlying immune dysregulation that drives them.

Red light therapy for rosacea

Rosacea — characterised by facial redness, visible vessels and skin sensitivity — shares the core mechanism of dysregulated inflammation with eczema and psoriasis. Red light therapy’s anti-inflammatory action directly addresses the vascular inflammation that drives rosacea, with studies showing reductions in redness and inflammatory activity with regular sessions.

For rosacea sufferers whose skin reacts to heat, friction and many topical products, the non-contact, gentle nature of red light therapy is particularly relevant. Sessions produce no irritation and are suitable for even highly reactive skin.

Red light therapy for skin ageing and collagen

Beyond inflammatory skin conditions, red light therapy has one of the strongest evidence bases of any non-invasive approach to skin ageing. Studies have demonstrated collagen production increases of 138–211% with regular therapy, alongside measurable improvements in skin texture, tone and elasticity.

For anyone wanting to maintain their skin health long-term — whether they have a specific condition or simply want to age well — regular red light sessions support skin from the inside of the cell outwards in a way no topical product can replicate.

Regular red light therapy supports collagen, elasticity and skin repair at a cellular level — in a way no topical product can replicate.

Why whole body red light therapy is different to home devices

Home red light panels and devices have their place, but they differ from clinical whole body therapy in important ways. Our whole body pod delivers significantly higher irradiance than consumer devices, treats your entire body in a single 15–20 minute session rather than one small area at a time, and uses precisely calibrated wavelengths at therapeutic intensities.

For conditions like eczema and psoriasis that involve systemic inflammation across large areas of the body, this difference is clinically meaningful.

A note on home devices: consumer red light panels vary widely in output, wavelength accuracy and coverage area. Many do not reach the therapeutic irradiance needed to produce systemic effects. Medical-grade whole body red light therapy is categorically different in its output, coverage and clinical outcomes.

What to expect at Aim Health

Sessions last 15–20 minutes. You stand or lie in our whole body red light pod, surrounded completely by therapeutic wavelengths. Sessions are painless, warm and relaxing — most clients find them deeply comfortable. There is no recovery time and you can return to normal activities straight away.

For skin conditions, most clients notice initial improvements within 4–8 sessions. A typical course is 10–12 sessions, with many clients continuing with regular maintenance sessions to keep their skin stable. Our team will advise on the right frequency and approach for your specific situation during your free wellness assessment.

Cryotherapy and red light therapy work particularly well together for inflammatory skin conditions — addressing the same underlying problem through complementary mechanisms. You can read more about the combination approach in our article: Cryotherapy for Eczema and Skin Conditions.

Frequently asked questions

Is red light therapy safe for sensitive skin?

Yes — red light therapy produces no UV radiation and has no known side effects. It is completely non-contact and suitable for all skin types including highly sensitive or reactive skin. Importantly, red and near-infrared light works through a photochemical process, not a thermal one — it does not generate heat, making it suitable for eczema-prone skin that reacts to warmth.

How many sessions will I need?

Most clients with eczema or psoriasis notice initial improvements after 4–8 sessions, with more significant changes over a 10–12 session course. We recommend a free wellness assessment before starting so we can advise on the right programme for you.

Can I use it alongside my existing treatments?

Yes — red light therapy works well alongside conventional skin treatments and prescribed medication. We always recommend continuing any treatment plan from your GP or dermatologist alongside your sessions at Aim Health.

Will it work for me?

We can’t guarantee results for any individual. What we can say is that the clinical evidence is positive, our clients’ experiences are consistently encouraging, and red light therapy has no known side effects. The best starting point is a free wellness assessment where we can discuss your situation properly.
