Does LED Light Therapy Work on Psoriasis?

Living with psoriasis can be frustrating, uncomfortable, and sometimes painful. The condition often causes red, scaly patches on the skin that flare up unexpectedly, leaving many people searching for effective relief. Among the emerging solutions is LED light therapy, a treatment that has gained popularity for its skin-healing benefits. But the big question is: does LED light therapy work on psoriasis?

In this article, we’ll explore what psoriasis is, how LED light therapy works, the science behind it, and whether it could be a safe and effective option for managing psoriasis symptoms.

What Is Psoriasis?

Psoriasis is a chronic autoimmune skin condition that accelerates the life cycle of skin cells. This rapid turnover leads to the build-up of thickened, inflamed, and scaly patches on the skin. It is not contagious, but it can significantly affect confidence, comfort, and quality of life.

There are several types of psoriasis, including:

  • Plaque psoriasis – the most common form, with raised, red patches covered by silvery scales.

  • Guttate psoriasis – small red spots, often triggered by infections.

  • Inverse psoriasis – smooth, inflamed lesions in skin folds.

  • Pustular psoriasis – white pustules surrounded by red skin.

Common Triggers

Psoriasis flare-ups can be triggered by:

  • Stress

  • Cold weather

  • Certain medications

  • Alcohol consumption

  • Skin injuries

  • Infections

Managing psoriasis often requires a combination of treatments and lifestyle adjustments. That’s where therapies like LED light therapy come into the picture.

What Is LED Light Therapy?

LED light therapy uses specific wavelengths of light to penetrate the skin at different depths. Unlike UV light, which can sometimes cause damage if overused, LED therapy is non-invasive and considered safe for home or professional use.

The two most common types of LED light used in skincare are:

  • Red light (630–700nm): Promotes healing, reduces inflammation, and stimulates collagen.

  • Blue light (400–470nm): Helps reduce bacteria and may calm irritated skin.

For psoriasis specifically, red and near-infrared light are the most promising wavelengths due to their anti-inflammatory and skin-repairing effects.

Does LED Light Therapy Work on Psoriasis?

The short answer: Yes, LED light therapy can help manage psoriasis symptoms for many people.

Research suggests that LED therapy may reduce redness, scaling, and inflammation. Unlike UVB light therapy, which is a well-established medical treatment for psoriasis, LED therapy works in a gentler way, helping to calm the overactive immune response that causes skin flare-ups.

Scientific Evidence Supporting LED Therapy for Psoriasis

Several studies have shown positive results:

  • Red light therapy has been found to reduce inflammation in psoriatic lesions.

  • Near-infrared light penetrates deeper layers of the skin, promoting cellular repair.

  • Some clinical trials have reported reduced itching, scaling, and faster healing times.

While LED therapy may not cure psoriasis, it can be a valuable tool in reducing discomfort and improving skin appearance.

Benefits of LED Light Therapy for Psoriasis

Here are the key benefits psoriasis sufferers may experience from LED light therapy:

1. Reduced Inflammation

Red light therapy calms inflamed skin and helps regulate the immune response, which is often overactive in psoriasis.

2. Improved Skin Healing

By boosting cellular repair and circulation, LED therapy encourages faster recovery of damaged skin.

3. Non-Invasive and Drug-Free

Unlike some topical creams or oral medications, LED therapy has minimal side effects and doesn’t require chemicals or steroids.

4. Safe for Home Use

With portable LED devices available, many people can manage flare-ups at home without frequent clinical visits.

5. Better Confidence and Comfort

When flare-ups reduce, skin looks and feels better—helping improve quality of life and confidence.

How to Use LED Light Therapy for Psoriasis

When considering does LED light therapy work on psoriasis, the results often depend on consistency and correct usage.

Professional Treatments

Dermatology clinics may use stronger LED or laser devices under medical supervision. These treatments can provide faster results but may require multiple sessions.

At-Home Devices

Many people are now turning to at-home LED masks and handheld devices to manage psoriasis. These are convenient, safe, and can be used regularly as part of a skincare routine.

Recommended Usage

  • Frequency: 3–5 sessions per week (depending on the device).

  • Session length: 10–20 minutes per session.

  • Wavelengths: Look for red (around 630–660nm) and near-infrared light (around 850nm).

Always follow manufacturer guidelines, and if you’re under medical treatment, consult your dermatologist before starting.

Are There Any Risks or Side Effects?

LED light therapy is generally considered safe, but there are a few points to keep in mind:

  • Eye protection: Always use protective goggles when treating areas near the face.

  • Mild irritation: Some people may experience temporary redness or warmth in the skin.

  • Medical conditions: Those with photosensitivity or on light-sensitive medications should seek medical advice before use.

Compared to UV therapy, LED light is safer as it doesn’t emit harmful radiation that can damage DNA or increase skin cancer risk.

Combining LED Therapy with Other Psoriasis Treatments

LED therapy often works best as part of a broader treatment plan. Many dermatologists recommend combining it with:

  • Moisturisers to prevent dryness.

  • Topical treatments like vitamin D creams.

  • Lifestyle adjustments such as reducing stress and avoiding triggers.

This combined approach ensures the best chance of keeping flare-ups under control.

Frequently Asked Questions

How long does it take to see results?

Some users notice improvements in 4–6 weeks, while others may take longer depending on severity.

Can LED therapy cure psoriasis?

No, psoriasis is a chronic condition. LED therapy helps manage symptoms but does not cure it.

Is it better than UVB light therapy?

UVB is clinically proven and stronger, but LED light therapy offers a safer, more accessible option with fewer risks.

Final Thoughts: Does LED Light Therapy Work on Psoriasis?

So, does LED light therapy work on psoriasis? The evidence shows that it can be an effective tool to reduce inflammation, promote healing, and improve the overall comfort of those living with psoriasis. While it’s not a cure, it provides a safe, non-invasive, and drug-free option for symptom relief—especially when combined with other treatments.

If you’re struggling with psoriasis flare-ups, exploring LED light therapy could be a step toward clearer, calmer skin.
