Psoriasis red light therapy

Psoriasis is a chronic skin condition that affects millions of people worldwide, causing red, scaly patches on the skin that can be both painful and embarrassing. While there is no cure for psoriasis, various treatments aim to manage its symptoms and improve the quality of life for those affected. One such treatment of psoriasis that has gained attention in recent years is red light therapy.

Red light therapy, also known as low-level laser therapy (LLLT) or photobiomodulation (PBM), is a non-invasive treatment that uses specific wavelengths of ultraviolet light to penetrate the skin and promote healing. This is low level light therapy because the most ultraviolet light is radiation, and light therapy has been used for various medical and cosmetic purposes, including wound healing, pain relief, and skin rejuvenation.

In this blog post, we will delve into the potential benefits of red light therapy for treating plaque psoriasis further, how it works, and what to consider before trying it. Our goal is to provide a comprehensive guide for those seeking alternative or complementary treatments for plaque psoriasis, helping you make informed decisions about your health and well-being.

Understanding Psoriasis

Psoriasis is a long-term autoimmune disease that causes skin cells to multiply more quickly on the skin's surface by speeding up their life cycle. Plaques, which are dense red spots coated with silvery scales, are the result of this accumulation. These plaques may itch, hurt, and occasionally even break and bleed.

Definition and Symptoms of Psoriasis

Psoriasis is characterized by several symptoms, including:

  • Red patches of skin are covered with thick, silvery scales.

  • Dry, cracked skin that may bleed.

  • Itching, burning, or soreness in the affected areas.

  • Thickened, pitted, or ridged nails are common in some cases.

  • Swollen and stiff joints, a condition known as psoriatic arthritis, which affects up to 30% of individuals with psoriasis.

Common Triggers and Areas of the Body Affected

Psoriasis can affect any part of the body, but it most commonly appears on the:

  • Scalp

  • Knees

  • Elbows

  • Torso

  • Palms and soles of the feet

The condition can be triggered or worsened by the adverse effects of various factors, including:

  • Stress: Emotional stress is a common trigger for psoriasis flare-ups.

  • Injury to the skin: Cuts, scrapes, bug bites, or severe sunburn can trigger psoriasis.

  • Infections: Certain infections, especially strep throat, can trigger psoriasis.

  • Certain medications: Some medications, such as lithium, antimalarial drugs, and high blood pressure medications, can trigger or worsen psoriasis.

  • Alcohol and smoking: Excessive alcohol consumption and smoking can exacerbate psoriasis symptoms.

The Emotional and Physical Toll of Living with Psoriasis

Red light therapy (RLT) has emerged as a promising treatment option for psoriasis, offering a non-invasive and drug-free approach to managing symptoms. In this section, we'll explore how RLT specifically targets psoriasis symptoms, the research supporting its use, and personal stories from individuals who have tried this effective therapy.

How Red Light Therapy Specifically Targets Psoriasis Symptoms

Red light therapy works by delivering specific wavelengths of ultraviolet light to the skin, which are absorbed by the mitochondria in cells. This absorption stimulates the production of adenosine triphosphate (ATP), the energy currency of cells, leading to enhanced cell function and regeneration. For psoriasis, RLT helps in several ways:

  • Reduces inflammation: RLT can decrease the production of inflammatory cytokines, which are involved in the development of psoriasis plaques.

  • Slows down cell growth: By regulating cellular processes, RLT can help slow down the rapid growth of skin cells that leads to plaque formation.

  • Alleviates itching and pain: RLT can help soothe the skin, reducing the itching and discomfort associated with psoriasis plaques.

Studies and Research Supporting the Use of Red Light Therapy for Psoriasis

Several studies have investigated the effectiveness of RLT in treating plaque psoriasis itself with two treatments, with promising results:

  • A study published in the Journal of the European Academy of Dermatology and Venereology found that RLT, combined with topical treatment, significantly improved psoriasis symptoms compared to topical treatment alone.

  • Another study in the Photomedicine and Laser Surgery journal reported that RLT reduced the size and severity of plaque psoriasis but did not treat plaque psoriasis but improved the quality of life for participants.

While more research is needed to fully understand the mechanisms and long-term effects of RLT for psoriasis, these studies suggest that it can be a valuable addition to existing treatment options.

Benefits of Red Light Therapy for Psoriasis
