Red light therapy (RLT) has shown potential as a complementary treatment for psoriasis, a chronic autoimmune skin condition that leads to the rapid buildup of skin cells, causing scaling, inflammation, redness, and itching. Red light therapy’s anti-inflammatory, immune-modulating, and skin-healing effects may help alleviate some of the symptoms associated with psoriasis, making it a promising non-invasive option for managing flare-ups and improving overall skin health.
How Red Light Therapy May Help with Psoriasis
- Reduces Inflammation
Psoriasis is characterized by chronic inflammation in the skin, which leads to the accelerated production of skin cells and the formation of plaques. Red light therapy has anti-inflammatory properties that can help reduce the skin inflammation associated with psoriasis by inhibiting pro-inflammatory cytokines. By calming the immune response, RLT may help reduce redness, swelling, and the discomfort caused by psoriasis plaques.A study published in Photomedicine and Laser Surgery demonstrated that red light therapy significantly reduced inflammation in patients with chronic skin conditions, including psoriasis, by modulating inflammatory pathways (Hamblin et al., 2017).
- Promotes Skin Healing and Regeneration
Red light therapy stimulates cellular repair by increasing the production of ATP (adenosine triphosphate), which provides energy for the cells. This enhanced cellular energy promotes faster skin healing and regeneration, helping to repair damaged skin caused by psoriasis flare-ups. By encouraging the healthy turnover of skin cells, RLT can help reduce the thickness of psoriasis plaques and improve the overall texture and appearance of the skin. - Reduces Itching and Discomfort
One of the most bothersome symptoms of psoriasis is intense itching, which can lead to skin irritation and scratching. Red light therapy helps alleviate itching by soothing the skin and reducing inflammation. By promoting better blood flow and cellular repair, RLT can also enhance the skin’s ability to retain moisture, reducing dryness and itching commonly associated with psoriasis. - Improves Skin Barrier Function
Psoriasis often disrupts the skin’s barrier function, leading to increased moisture loss and sensitivity to irritants. Red light therapy helps improve the skin’s barrier function by stimulating collagen production and promoting the regeneration of the skin’s protective layers. A stronger skin barrier can help prevent moisture loss, reduce irritation, and make the skin more resilient to environmental factors that may trigger psoriasis flare-ups. - Modulates Immune Response
Psoriasis is an autoimmune condition, meaning the body’s immune system mistakenly attacks healthy skin cells. Red light therapy has been shown to have immune-modulating effects, helping to balance the immune response and reduce the overactive production of skin cells. By calming the immune system, RLT may help reduce the frequency and severity of psoriasis flare-ups.
Scientific Evidence Supporting Red Light Therapy for Psoriasis
Although more research is needed specifically for red light therapy in psoriasis treatment, several studies have explored its benefits for inflammatory skin conditions:
- Inflammation Reduction: A study published in Photomedicine and Laser Surgery found that red light therapy reduced inflammation and improved skin health in patients with inflammatory skin conditions, including psoriasis (Hamblin et al., 2017).
- Skin Healing and Repair: Research published in Lasers in Medical Science demonstrated that red light therapy promoted faster skin healing and tissue repair, making it beneficial for individuals with psoriasis who experience damaged skin (Mittermayr et al., 2012).
- Immune Modulation: A study published in Lasers in Surgery and Medicine highlighted that red light therapy helped regulate immune responses in patients with autoimmune conditions, suggesting its potential to manage immune-related skin conditions like psoriasis (Avci et al., 2014).
How to Use Red Light Therapy for Psoriasis
- At-Home Devices
There are several FDA-approved red light therapy devices available for at-home use, such as handheld devices, light panels, and flexible wraps. These devices emit red and near-infrared light that penetrates the skin and can be used to target affected areas. Consistent use, typically 10-20 minutes per session, 3-5 times per week, may help manage psoriasis symptoms over time. - Wavelength and Intensity
The most effective wavelengths for treating psoriasis range between 630 nm and 850 nm. These wavelengths penetrate deeply into the skin, promoting healing and reducing inflammation without causing damage to the skin’s surface. Treatment duration and frequency will depend on the severity of the psoriasis and the device being used, but consistency is key to achieving results. - Combining with Other Treatments
Red light therapy can be used alongside other psoriasis treatments, such as topical steroids, moisturizers, and immune-modulating medications. In some cases, RLT can enhance the absorption and effectiveness of topical treatments by improving blood circulation and skin health. However, it’s essential to consult with a healthcare provider or dermatologist to ensure that RLT complements your current treatment plan.
Safety Considerations
- Consult with a Dermatologist: Before starting red light therapy for psoriasis, it’s important to consult with a dermatologist to ensure the therapy is appropriate for your condition. A professional can help determine the best treatment approach and monitor your progress.
- Avoid Overexposure: Follow the recommended treatment times and avoid overusing red light therapy, as excessive exposure can lead to skin irritation. Sessions should generally last between 10-20 minutes per area, several times per week.
- Monitor for Skin Reactions: While red light therapy is generally safe, it’s essential to monitor your skin for any signs of irritation, redness, or sensitivity. If you experience any adverse reactions, discontinue use and consult your healthcare provider.
Conclusion
Red light therapy offers potential as a complementary treatment for managing psoriasis by reducing inflammation, promoting skin healing, and modulating the immune response. Its ability to soothe itching, improve skin barrier function, and accelerate the repair of damaged skin makes it a valuable tool for individuals seeking non-invasive treatment options. While it is not a cure for psoriasis, consistent use of red light therapy, alongside other treatments, may help reduce the frequency and severity of flare-ups and improve overall skin health.
