Red Light Therapy: Eczema Treatment

Red-light treatment is an alternative way of treating eczema and has gained much popularity in recent days. It provides some relief to the people looking for different options for eczema control.

Eczema is a long-lasting skin disease in which the skin itches, becomes inflamed, and sometimes develops blisters. The process often utilizes common moisturizing cream and anti-inflammatory ointment, with Red Light Therapy tried when other common treatments do not work.

Red Light Therapy & Eczema

Red light therapy uses certain wavelengths to reduce inflammation in skin conditions like eczema. It uses precise wavelengths of red light to penetrate the skin, potentially reducing inflammation and soothing irritation. [1]

Understanding the Root Cause of Eczema

Eczema does not have a sole root cause. It is a complex condition with numerous types and triggers. The following can be potential causes for it:

Immune System: It is an immune system-mediated disease, with atopic dermatitis compromising the skin barrier such that it becomes dry, itchy, and inflamed. [2]

Genetics: The skin tends to be drier and more delicate because of filaggrin protein deficiency. A family history of eczema or any family members’ history of ever having related conditions increases the risk.

Stress: It can flare up symptoms of eczema or exacerbate them.

Environmental Factors: Every external stimulus can provoke or trigger eczema. [3] The most common of them are:

  • Harsh soaps, shampoos, and laundry deter
  • Dust mites, high temperatures, and low humidity levels in the air
  • Fragrance in personal care and candle
  • Some fabrics like wool and polyester

How Red Light Therapy Can Help With Eczema

Eczema has proven successful with red light therapy and LED light therapy, which—through the application of certain wavelengths—helps reduce inflammation and encourages skin healing. These include:

  • Reducing inflammation: Redness and irritated skin indicate inflammation associated with eczema; red light therapy may help reduce such overactive reactions of the immune system by acting on cellular mechanisms.
  • Improves Skin Repair: It has been reported that RLT increases the energy produced by cells called adenosine triphosphate (ATP), which energizes the repair of tissues and also increases cellular rejuvenation. [4]
  • Stimulates Collagen Production: RLT and LED lights stimulate the natural collagen formation, which strengthens the skin barrier and slows down its reactivity.
  • Relief from Itching: Itching is among the most common symptoms in eczema. RLT acts to soothe the irritated skin and lessens the urge to scratch.

How Red Light Therapy (RLT) Improves Overall Skin Health

Red light therapy has come to the fore as a non-invasive modality in the treatment of various skin conditions and, potentially, general well-being. [5] This is through its ability to penetrate the skin and increase cellular activity.

When applied on the skin, this red light will increase ATP, which acts as the fuel source of energy to cell repair, reduce inflammation, and will stimulate fibroblasts, which produces collagen in the body, thereby reducing wrinkles and fine lines.

What Does the Science Say About Red Light Therapy & Eczema?

Studies suggest red light therapy could be an effective treatment for eczema. In a trial, researchers found that even a single 2-minute session of red light therapy per week significantly improved eczema symptoms, including:

  • Redness
  • Bumpy skin
  • Flaking
  • Swelling and pimples

Patients also reported less itchiness and fewer leathery patches. The trial noted no side effects, indicating that red light therapy is safe. Given these positive results, researchers concluded that it could become a new standard for treating eczema.

A 2013 study with immunosuppressive drugs and red light therapy found reduced skin lesion inflammation and improved skin barrier function. A 2017 study using SCORAD, a clinical tool for measuring eczema severity, confirmed reduced skin thickness, allergic cells, and dead cells after red light therapy. [6]

Eczema & Current Treatment Limitations

Current treatment focuses on the management of symptoms without addressing the root causes, leaving room for the symptoms to reoccur and be treated all over again. While there is a myriad of treatments that could be used to manage these symptoms, there are several limitations on the part of the treatments.

The problem, however, is that there are possibilities for side effects. Topical corticosteroids, usually prescribed to reduce inflammation, may thin out the skin if used for too long. [7] Oral medications, including corticosteroids and calcineurin inhibitors, can increase the risk of infection.

Therefore, researchers are in search of new approaches that would possibly target the actual problems and offer sustainable solutions.

Using At-home Red Light Therapy for Eczema

At-home red light therapy for eczema is a useful option for managing eczema, offering convenience and effective symptom relief. [8] These devices use specific wavelengths of red and near-infrared light to reduce inflammation, promote healing, and relieve itching.

Consistency is the key, so follow the directions for the device you have, and come up with a regular schedule. At-home therapy is flexible in that it could be managed around your personal schedule.

Choosing the Best At-home Red Light Therapy Device

When selecting between at-home and in-clinic red light therapy for eczema, consider these key points:

  • Ease of Use: Choose a user-friendly device with clear instructions.
  • Convenience and Lifestyle: At-home therapy offers flexibility and privacy, while in-clinic sessions are more suitable for severe cases, providing expert guidance.
  • Power and Control: In-clinic devices are more powerful and precisely controlled, while at-home devices are less potent but offer more freedom.
  • Consistency and Frequency: Effective therapy requires regular sessions. Treatments usually last 10 to 20 minutes and are recommended several times weekly.
  • Quality and Safety: These devices are generally safe and non-invasive. Opt for FDA-cleared products and read reviews for reliability.

Summary: How to Best Use Red Light Therapy for Eczema

Red light therapy (RLT) can be a valuable tool for managing eczema, offering a non-invasive way to reduce inflammation, promote skin healing, and relieve itching. Aim for 10 to 20-minute sessions a few times a week to get the most benefit. [9]

Frequently Asked Questions – FAQs
  • Yes, it can reduce inflammation and relieve symptoms like itching, promoting temporary healing. However, it is not a long-term cure for eczema.
  • Improvements in eczema symptoms may take one or two months of consistent light therapy. After that, the frequency of sessions might be reduced or paused to check if the eczema is in remission.
  • Eczema is not usually "cured," but treatment can lead to clear skin for a period. Symptoms may take several weeks to improve with topical or oral medication. If symptoms persist or worsen after a few weeks, consult your healthcare provider.
