Harnessing the Power of Light: Phototherapy and Red Light Therapy for Eczema
Unravel how phototherapy and red light therapy can help manage eczema.
What We'll Cover - Phototherapy and Red Light Therapy.
Key Takeaways
Phototherapy uses UV light, red light therapy uses red light.
Phototherapy reduces skin inflammation, red light therapy promotes cell healing.
Both help manage eczema but differ in cost, use, and safety.
Introduction to Light Therapy: Phototherapy and Red Light Therapy for Eczema
Welcome to our comprehensive guide on light therapy for eczema, where we'll focus on two specific types - phototherapy and red light therapy. In this blog post, we'll explain what these therapies are, delve into how they work, and highlight their role in managing eczema. We'll also discuss their pros and cons, how to use them effectively, and how they fit into your overall skincare routine. Plus, we'll explore the similarities and differences between phototherapy and red light therapy.
Understanding Phototherapy and Red Light Therapy
Phototherapy, also known as light therapy, uses natural or artificial ultraviolet (UV) light to treat various skin conditions, including eczema. The therapy involves exposing the skin to controlled amounts of UV light on a regular schedule. This can help to slow the growth of skin cells and reduce inflammation, both of which play a significant role in eczema flare-ups.
Red light therapy, a subset of phototherapy, uses wavelengths of red and near-infrared light. Rather than relying on UV light, red light therapy works at a cellular level. The red and near-infrared light penetrate deep into the skin, where they can reduce inflammation and increase cellular metabolism. This can lead to enhanced healing and a reduction in the symptoms of eczema.
The Impact of Light Therapy on Eczema: Academic Research
Several research studies have pointed to the effectiveness of both phototherapy and red light therapy in managing eczema symptoms. In the case of phototherapy, a review in the Journal of the American Academy of Dermatology highlighted that this form of treatment could significantly reduce eczema severity in a majority of patients.
Similarly, red light therapy has shown promise in several studies. A study published in the Journal of Photochemistry and Photobiology found that red light therapy could effectively improve the skin barrier function, reduce itching, and enhance the overall quality of life for eczema sufferers.
The Differences Between Phototherapy and Red Light Therapy
While both phototherapy and red light therapy are forms of light therapy used to manage skin conditions, they differ in terms of their operational wavelengths and the way they're used. Phototherapy uses ultraviolet light and typically requires a medical setting, while red light therapy uses red and near-infrared light, and can be conveniently performed at home with a suitable device.
How Phototherapy Works
Phototherapy, also known as light therapy, uses natural or artificial ultraviolet (UV) light to treat various skin conditions, including eczema. The therapy involves exposing the skin to controlled amounts of UV light on a regular schedule. The UV light acts on the skin cells (specifically T cells) that are part of the immune system and cause inflammation - a hallmark of eczema.
By suppressing these cells, phototherapy can help to slow the growth of skin cells and reduce inflammation, which helps to manage the symptoms of eczema. Phototherapy can also improve the skin's barrier function, providing it with better protection against environmental factors that can make eczema worse.
Phototherapy Suitability and The Pros and Cons
Procedure: Individuals undergoing phototherapy are usually asked to stand in a lightbox, a device that releases UV light, wearing only underwear and protective goggles. The session typically lasts a few minutes, and the therapy is usually administered two to three times a week over a few months.
Suitability: Phototherapy is generally suitable for individuals with moderate to severe eczema who have not responded well to topical treatments. However, it's not recommended for those who have a history of skin cancer or conditions that make their skin more sensitive to sunlight.
Pros: It's effective for many people; it can be used on large areas of the skin; and it can be combined with other treatments.
Cons: It requires regular hospital or clinic visits; there is a small risk of skin ageing and skin cancer; it may cause side effects like burning or dry skin; and improvements may take several weeks to become noticeable.
How Red Light Therapy Improves Eczema and How It Works
Red light therapy, a subset of phototherapy, uses wavelengths of red and near-infrared light. Rather than relying on UV light, red light therapy works at a cellular level. The red and near-infrared light penetrate deep into the skin, reaching parts of the skin cells called mitochondria. The mitochondria are the energy producing parts of the cell and the light helps to stimulate the production of adenosine triphosphate (ATP), the energy source for cells.
The increased ATP fuels cell repair and regeneration, leading to improved healing. Additionally, red light therapy can reduce inflammation and oxidative stress, which are often elevated in eczema. This multi-pronged action can result in a reduction in the symptoms of eczema, improvement in the skin's texture and appearance, and better control of the condition.
Using Red Light Therapy Effectively for Eczema
Red light therapy can be administered using a handheld device. For optimal results, the device should be held about 6 to 12 inches away from the skin. A typical session lasts around 10 to 20 minutes and can be performed daily. The therapy is often done after cleansing the skin and before applying skincare products.
Here are a few example devices that you can try:
Always make sure that you choose a product that has been clinically tested for safety and efficacy.
Pros and Cons of Red Light Therapy for Eczema
Pros:
Convenience: Red light therapy devices can be used in the comfort of your home and at your convenience. No frequent hospital or clinic visits are required.
Improves Skin Health: Regular usage can help to improve skin barrier function, reduce itching, and enhance skin texture and appearance.
Safety: Red light therapy is considered safe with few reported side effects. Unlike UV-based phototherapy, it does not increase the risk of skin cancer.
Results: Many people see improvements in their eczema symptoms within a few weeks of consistent use.
Cons:
Cost: The initial cost of buying a red light therapy device can be high. However, considering the long-term usage, it may be a worthwhile investment.
Time Commitment: Effective use of red light therapy requires daily sessions, which might be challenging for those with a busy schedule.
Individual Variations: As with many treatments, its effectiveness can vary among individuals. Some may see significant improvements, while others may see only mild benefits.
