Red Light Therapy For Eczema: Does It Really Work?

Eczema is a common skin disease that appears as red, swollen, itchy, oozing, and crusted skin. The causes of eczema are complex, and although many treatment methods are available, the desired effect is not always achieved. After undergoing repeated treatments and experiencing recurrent episodes of pain, many patients lose faith in their treatment.

There is new hope for patients suffering from eczema in the form of red light therapy. Red light therapy for eczema uses specific wavelengths of red light that are shone on the skin to improve skin conditions. It works by stimulating skin cells to produce cytokines, which boost the metabolism of skin cells, speed up wound healing, and reduce inflammation.

Red Light Therapy For Eczema: Does It Really Work?

Factors That Cause Eczema

Some of the common triggers include stress, allergens, irritants, infections, changes in temperature, and certain foods. It is important to identify the factors that cause your eczema to flare up so that you can take steps to avoid them and keep your skin healthy.

Several factors can contribute to a defective skin barrier in eczema:

  • Genetics: A family history of eczema or related allergic conditions like asthma increases risk. Defects in filaggrin, a protein important for skin barrier function, are linked to eczema development.
  • Immune system dysfunction: Eczema is linked to overactivity of the immune system and inflammation.
  • Barrier dysfunction: The outer layer of the skin fails to retain moisture and protect against irritants.
  • Triggers: Things like stress, hot showers, soaps, detergents, dust mites, and certain fabrics can trigger flare-ups.
  • Microbe: bacteria like staphylococcus aureus colonize the skin of many eczema patients, worsening inflammation.
  •  Stress: stress hormones may inhibit skin barrier repair and amplify itch intensity.

The goal of treatment is to reduce inflammation and itch during flares. This helps prevent infection and damage to the skin from excessive scratching.

Why Can Red Light Therapy For Eczema?

Red light is thought to deliver the following benefits that may relieve eczema:

  • Reduces Inflammation: Red light exposure has anti-inflammatory effects on the body. It can calm pro-inflammatory cytokines and immune activity implicated in eczema flares.
  • Repairs Skin Barrier: By stimulating cells called fibroblasts, red light encourages collagen production and helps rebuild the damaged skin barrier seen in eczema.
  • Improves Circulation: Red light boosts microcirculation in the skin. Improved blood flow provides nutrients, removes waste, and promotes healing.
  • Eases Itch: Red light is thought to reduce itch by interacting with nerves in the skin and stabilizing mast cells (allergy cells) that release histamine.

So in summary, red light therapy helps create an environment to heal the skin at a cellular level.

Studies Support

Clinical studies support red light therapy as an effective complementary treatment for eczema.

A study explores the clinical efficacy of narrow-band medium-wave ultraviolet, red light, and low-power helium-neon laser combined in treating post-burn eczema. 80 patients were selected and divided into four groups for different treatments. The results showed that the combined treatment group was superior to single drug treatment in terms of effective time and efficacy, without obvious adverse reactions.

A recent study delves into the possible applications of light-emitting diodes (LEDs) in the fields of dermatology and aesthetics. A study finds red  lights have a significant effect on eczema vulgaris treatment

While more research is welcome, current evidence supports red light as an adjunct treatment for moderate to severe eczema. It consistently ameliorates symptoms, heals skin damage, and improves patient quality of life.

It Is Both Safe And Effective

Red light therapy is a non-invasive treatment that does not cause any damage to the skin. Proper red light devices are designed to be safe and gentle. Visible red wavelengths are used at low-intensity levels. High-quality home devices have irradiance levels similar to sunlight. Overall, red light therapy is very well-tolerated with an exceptional safety profile. So you can feel confident adding it to your eczema treatment routine.

Using Red Light Therapy to Soothe Eczema At Home

If you want to add red light therapy to your treatment list, here are some tips:

  • Clean & Dry Skin: Cleanse and thoroughly dry the treatment area to maximize light penetration into the skin. Try to avoid creams, oils, or moisturizers beforehand.
  • Position Device & Expose Skin: Place the red light panel directly over the clean treatment area, about 2-4 inches from the skin. Expose as much affected skin as possible to ensure sufficient coverage.
  • Begin Treatment: Turn on the device. Most quality home units automatically deliver the ideal power density and wavelengths of therapeutic red light.
  • Continue Session: Maintain the position, keeping light beams focused on eczema-affected skin for the full treatment session. Typical times range from 5-20 minutes depending on the device and severity.
  • Repeat Regularly: Consistent daily use provides cumulative benefits, so aim for ongoing treatments. Most people see improvements within 4-6 weeks. Maintenance sessions can continue 1-3 times per week.
  • Track Progress: Keep notes on changes in inflammation, discomfort, and appearance of skin over time. Take photos to compare. Adjust treatment times and frequency as needed.

Be patient and committed to the process for best eczema relief with red light therapy. Results improve over a series of sessions as your skin heals at the cellular level.
