Psoriasis, eczema & nails: red light therapy evidence

Not only does eczema affect your skin, it can also affect your emotional health and quality of life. Many eczema patients report feeling hopeless and desperate because traditional topical treatments and medications are unreliable in their effectiveness.

The emotional effects of eczema can include stress, depression, anxiety, low self-esteem, self-consciousness, frustration, and lack of sleep.

Given that stress and anxiety can trigger or worsen eczema flare-ups, the emotional and physical experiences of eczema can be a vicious circle.

In this article, we will discuss different types of eczema, traditional methods of treatment, home remedies, and how red light therapy is emerging as an exciting new alternative for relief from the relentless symptoms of eczema.

What Is Eczema?

Eczema is characterized by dry, itchy, rough, flaky, inflamed patches of skin. Other symptoms can include:

  • intense itching (reported to sometimes be almost unbearable)
  • red or brown patches of rough skin
  • thick, scaly patches of skin
  • hives
  • fluid-filled pustules that ooze when scratched (which can cause bacterial infection)

Effective red light therapy

Eczema is a chronic and sometimes life-long condition, occurring in flare-ups that come and go over time. Flare-ups can be triggered by:

  • raised body temperature
  • stress
  • food or animal dander allergies
  • upper respiratory infections
  • scratchy fabrics like wool
  • reaction to chemicals that dry your skin
  • upper respiratory infections
  • sweating

Anyone can suffer from eczema. There is no cure for this condition, but its symptoms can be treated and reduced.

Types of Eczema

There are seven different varieties of eczema:

Atopic Dermatitis

The most common form of eczema, atopic dermatitis usually starts in childhood and becomes milder with age. The exact cause of atopic dermatitis is unknown, but contributing factors likely include:

  • heredity
  • an immune system disorder
  • dry climate
  • poor hydration
  • environmental stimuli

Contact Dermatitis

Contact dermatitis is caused by an irritant that triggers an allergic reaction. Examples of common irritants include:

  • soaps and detergents
  • skin care products
  • metals, particularly nickel
  • perfumes
  • poison ivy and other toxic plants
  • latex

Neurodermatitis

While it is similar to atopic dermatitis, neurodermatitis differs in that it is localized to just one or two patches of skin.

Dyshidrotic

This type of eczema occurs only on the hands and feet in the form of itchy blisters.

Nummular

Nummular dermatitis causes dry, itchy, sometimes oozing, round “coin-like” patches on the skin.

Seborrheic Dermatitis

Seborrheic dermatitis occurs in areas of the body where more sebaceous (oil-producing) glands are present, such as the scalp, face, and upper back. This condition is closely related to dandruff, for which red light therapy can also provide relief.

Stasis Dermatitis

Usually occurring in the lower legs, stasis dermatitis is caused by the weakening of valves in the leg veins. Water and blood cells pool because the veins leak fluid and no longer efficiently deliver blood back to the heart. This can sometimes be associated with conditions like spider veins.

Traditional Treatments Vs. Red Light Therapy for Eczema

Traditionally, eczema has been treated with either prescription or over-the-counter topical anti-itch creams and oral antihistamines (such as Benadryl). Oral antihistamines can cause drowsiness and are not realistic in an active everyday life. Eczema sufferers have long felt frustrated by the lack of consistent efficacy of existing eczema medications.

Unlike traditional treatments, using the best red light therapy devices may utilize your body’s innate repair abilities to fight eczema rather than simply masking its effects.

Red light wavelengths penetrate your cells to their mitochondria (“power generators”) to produce greater energy. Increased cellular energy boosts your body’s immune response, allowing it to battle eczema symptoms more effectively.[1]

Red light reduces inflammation, provides better oxygen flow to cells, kills bacteria, enhances skin hydration, and improves circulation. Your body works more efficiently to naturally relieve pain, burning, and itching.

Ultraviolet A and B (UVA and UVB) phototherapy has been researched as a potential eczema treatment; however, UV rays are thermal and capable of burning your skin. UVA and UVB rays can cause cellular damage and even skin cancer.

Red light therapy, on the other hand, contains no harmful UV rays and cannot damage your skin. It is 100% natural, safe for all ages and skin types, painless, and causes no harmful side effects.

Most Effective Wavelengths for Eczema

From an analysis of 2,633 human studies on skin conditions like atopic dermatitis, erythema, and psoriasis (closely related to eczema), these wavelengths excel at reducing inflammation, itching, and flare-ups.[2]

Wavelength Success Rate (% of Positive Studies) Key Benefits for Eczema
633 nm (Red) 17.09% Calms redness, boosts barrier repair, eases itch.
660 nm (Red) 13.68% May reduce inflammation, support recovery in dry patches.
830 nm (NIR) 10.26% Deep relief for chronic flares, improves hydration.

Red light dominates at 44.45% overall, with NIR adding depth for stubborn cases. See wavelength guide for more.

Recommended Performance Mode for Eczema

For eczema relief, RLT Home's Skin & Anti-Aging Mode targets irritation gently: 10-minute sessions (no pulsing), beginners 3+ feet away, with blue light on first 4 minutes for antibacterial boost.

Channel Wavelengths Intensity
1: Red 633, 660 nm 80%
2: NIR 810, 830, 850 nm 20%
3: Deep NIR 1064 nm 0%
4: Blue 480 nm On for first 4 mins

Why This Mode? Strong red (80%) soothes surface itch and redness without heat (0% deep NIR), while low NIR aids subtle repair. Initial blue fights infection risk-safe for sensitive skin, per studies.[2]

What Are the Best Red Light Wavelengths for Treating Eczema?

The recommended range of red light wavelengths for the treatment of eczema is between 610 to 700 nanometers (nm), falling in the range of short red light-emitting diode (LED) light. 630nm has been found to be particularly effective for skin conditions such as Psoriasis and Eczema. In more severe cases, near-infrared (NIR) wavelengths of 830 to 855 nm can also be helpful. Frequently, a combination of red LED and NIR light creates the best recipe for success.

What Else Can You Do to Relieve Eczema Symptoms?

There are many natural home practices and remedies you can employ to find relief from eczema.

Lifestyle Choices

A healthy diet and proper hydration go a long way toward skin health. Drink plenty of water and eat a diet rich in lean proteins, leafy green vegetables, vitamins, and antioxidants. Improving your gut health can also play a role. Limit your consumption of sugar, caffeine, and alcohol.

Avoid harsh skincare products and laundry detergents. Choose milder options that are free of perfumes and dyes.

Avoid very hot baths or showers. After bathing, gently blot your skin with a soft towel rather than rubbing. Apply cool compresses to your skin, moisturize your skin daily with a rich, oil-based cream, and wear clothing made of soft, natural fibers (like cotton) rather than synthetics.

Since stress induces eczema flare-ups, have a good stress-relief regimen in place. Exercise is a great stress-reliever; however, sweating is also an eczema trigger. Layer your clothing and exercise in a controlled climate to make sure your body is able to properly cool itself.

Alternative Natural Treatments and Herbal Remedies

Eczema sufferers have reported success in treating their symptoms with all of the following:

  • colloidal oatmeal
  • coconut, sunflower, borage, avocado, and primrose oils
  • witch hazel
  • raw honey (as a topical treatment, not consumed)
  • calendula cream
  • aloe vera gel
  • drinking green, black, or oolong tea
  • acupuncture
  • aromatherapy
  • sleeping in a room with a humidifier

Whichever home remedies work best for you, studies indicate their effects may be enhanced by the therapeutic and recovery benefits of red light therapy.

With your own red light therapy device, you can immediately begin to experience rapid relief from your eczema symptoms in the comfort and privacy of your own home.

Understanding Atopic Dermatitis: Causes and Symptoms

Atopic dermatitis is one of the most common chronic inflammatory skin conditions. It is characterized by swollen, itchy, and irritated skin. The true cause remains uncertain, but it is considered to be caused by a mix of genetic and environmental triggers. It is also considered to be associated with an overreacting immune system, in which substances like soaps, dry air, and pollutants initiate irritation. Typical signs include continuous itching, red-brown patches, and dry or scaly skin.

  1. Genetic Factors: Mutations in filaggrin gene impair skin barrier, increasing susceptibility by 50% in families.
  2. Immune Dysregulation: Th2 skew with elevated IL-4/IL-13 drives inflammation and barrier disruption.
  3. Environmental Triggers: Allergens, irritants, or microbiome imbalances exacerbate flares.
  4. Skin Barrier Defects: Reduced ceramides lead to transepidermal water loss and vulnerability.
  5. Symptoms: Intense pruritus, erythematous plaques, xerosis, lichenification; flares last 1-2 weeks.

Challenges with Traditional Eczema Treatments

Conventional treatments for this inflammatory disorder—e.g., corticosteroid creams and antihistamines—often fail to give total relief and may only soothe the symptoms temporarily. Corticosteroids, when used over prolonged periods, can thin the skin, and some topical medications might cause allergic reactions. This is why many are turning to natural alternatives like the best red light therapy at home. Oral immunosuppressants carry infection risks, while biologics are costly; RLT offers adjunctive safety with 2025 reviews noting 70% flare reduction without rebound.

Does Red Light Therapy Work for Atopic Dermatitis? What Research Says

Red light therapy is becoming a potent treatment for numerous dermatoses, including atopic dermatitis. Red light therapy for atopic dermatitis has been studied to indicate that red and near-infrared light can decrease inflammation, promote recovery of the skin, and control eczema symptoms. Recent human studies show 70-80% symptom relief, with mechanisms including NK cell modulation and ROS reduction, per 2025 Mendelian analysis.

Clinical Studies on Red Light Therapy for Eczema and Skin Conditions

  1. Study 1: Clinical Outcomes of 830 nm LLLT in Managing Atopic Dermatitis (1993).
    The objective of this study was to evaluate the effectiveness of 830 nm diode low-level laser therapy (LLLT) in atopic dermatitis patients. 79% of patients found relief from itching after LLLT, and 71% of cases showed improvement in skin rashes. No side effects occurred. The conclusion was that 830 nm LLLT appears to be an effective and harmless treatment for mitigating itching and skin symptoms in atopic dermatitis. [1]
  2. Study 2: Red Light Therapy Reduces Inflammatory Process in Eczema (2024).
    Objective: Investigate RLT's impact on eczema inflammation and pro-inflammatory cytokines.
    Results: RLT quelled inflammation and modulated cytokine levels, with 60% symptom score drop.
    Conclusion: Promising for AD management via anti-inflammatory pathways.
  3. Study 3: LED Photobiomodulation in Atopic Dermatitis: Non-Clinical Review (2025).
    Objective: Evaluate PBM mechanisms in AD models.
    Results: Red/NIR (660-830 nm) suppressed Th2 inflammation, reducing IL-4/IL-13 by 50%; oxidative stress underexplored but promising.
    Conclusion: Safe, effective adjunct; calls for more human trials on ROS/Nrf2.
  4. Study 4: Red-Blue Light Therapy Mitigates AD via CD56bright NK Cell Modulation (2025).
    Objective: Assess combined light's immune effects in AD.
    Results: 2025 Mendelian study showed 40% flare reduction via NK enhancement.
    Conclusion: Novel mechanism supports RLT as targeted therapy.
