Red Light Therapy for Psoriasis: A Natural Way to Soothe Your Skin

If you or someone you love struggles with psoriasis, you know it’s more than just a skin condition—it can affect your confidence, your comfort, and your quality of life. While prescription creams, phototherapy, and systemic medications are common treatments, many people are looking for a gentler, non-invasive alternative with fewer side effects. That’s where red light therapy (RLT) comes in.

Backed by growing scientific interest, red light therapy is emerging as a promising option for managing psoriasis symptoms. Here’s what you need to know about how it works, what the research says, and how to incorporate it into your wellness routine.

What Is Red Light Therapy?

Red light therapy involves exposing the skin to low levels of red or near-infrared light (typically in the 620–850 nm wavelength range). Unlike ultraviolet (UV) light, which can damage skin cells and increase cancer risk, red light penetrates the skin gently to stimulate cellular repair, reduce inflammation, and improve blood flow.

This therapy can be delivered through LED panels, handheld devices, light beds, or in clinical settings—making it accessible for both at-home and professional use.

How Does Red Light Therapy Help Psoriasis?

Psoriasis is an autoimmune condition that causes the skin to regenerate too quickly, leading to inflammation, redness, and scaly plaques. Red light therapy helps target several root issues associated with psoriasis:

1. Reduces Inflammation

One of the primary benefits of red light therapy is its anti-inflammatory effects. Psoriasis flare-ups are characterized by excessive inflammation in the skin. Red light helps downregulate pro-inflammatory cytokines, which are key drivers in the psoriasis response.

2. Promotes Skin Healing

Red light stimulates the production of ATP (adenosine triphosphate), the energy source for cellular repair and regeneration. This promotes faster healing of damaged skin, so psoriasis plaques may resolve more quickly with consistent treatment.

3. Improves Blood Circulation

Better circulation means more oxygen and nutrients reach the skin, supporting natural detoxification and reducing irritation. This can help reduce the thick, scaly buildup common in chronic psoriasis patches.

4. Helps Normalize Skin Cell Turnover

Psoriasis is marked by an overactive immune system that accelerates skin cell production. Red light therapy helps balance this process, potentially slowing down the overproduction and reducing plaque formation.

What Does the Research Say?

While more large-scale studies are still needed, early clinical evidence is promising:

• A 2010 study published in Photomedicine and Laser Surgery reported that patients with chronic psoriasis treated with red and near-infrared light therapy experienced significant improvement, with 60–100% clearance of lesions in some cases.

• Another small trial found that twice-weekly RLT sessions for several weeks led to substantial reductions in plaque thickness and redness, without adverse effects.

Importantly, red light therapy is generally well-tolerated and does not carry the same risks as UV-based therapies or long-term steroid use.

Is Red Light Therapy Safe for Psoriasis?

Yes—for most people, red light therapy is considered safe, non-invasive, and painless. It does not burn the skin or cause DNA damage like UV light, making it suitable for regular use. However, it's always smart to consult your dermatologist, especially if you're on medications that increase light sensitivity.

Tips for Using Red Light Therapy at Home

If you're thinking about trying red light therapy for your psoriasis, here are some practical tips:

• Choose the right wavelength: Look for devices that emit light in the 630–850 nm range.

• Be consistent: Aim for 10–20 minute sessions, 3–5 times per week, for several weeks to see results.

• Stay patient: While some people notice improvements within a few sessions, others may take several weeks to see visible changes.

Final Thoughts

Red light therapy offers a natural, side-effect-free way to manage psoriasis symptoms and support overall skin health. Whether used as a complementary therapy alongside conventional treatments or as part of a holistic approach, RLT is worth considering—especially for those looking for gentle and sustainable solutions.

With more research emerging and at-home devices becoming more affordable, there’s never been a better time to explore this therapeutic light for brighter, calmer skin.
