Red, dry, itchy skin is a tell-tale sign of one of the most common—and most irritating—skin conditions: eczema. And although flare-ups can happen all year long, they tend to get worse in winter, when the air is drier and we're washing our hands more frequently.
As a refresher, "Eczema, also known as atopic dermatitis, is a chronic inflammatory skin condition that is very common in both children and adults," explains Kunal Malik, a board-certified dermatologist at Mount Sinai Hospital in New York City. "It's characterized by dry, itchy, inflamed skin and a compromised skin barrier."
According to the National Eczema Association, 31.6 million people in the U.S. have the skin condition. Although it is usually treated topically with emollient balms, creams, and lotions, red light therapy may be a more effective treatment option.
Ahead, learn more about how red light therapy can help with the chronic skin condition, with expert intel courtesy of Malik as well as Richard Hsu, a licensed acupuncturist at ORA.
What Is Red Light Therapy?
“Red light therapy is an energy-based modality that uses specific wavelengths of red and near-infrared light (typically 630-850nm) to penetrate the skin and interact with cells,” explains Malik. “It can stimulate cellular energy production and promote healing at the cellular levels and can have a variety of benefits.”
Those benefits can include everything from reducing the appearance of wrinkles and scars to, yes, even soothing eczema.
There are red light therapy tools for at-home use, or it can also be done on professional-grade machines. “A common misconception is that any device will offer the same results. Using devices that do not emit the correct wavelengths of light can lead to ineffective treatments,” says Hsu. “Additionally, low-quality devices may not provide the necessary irradiance output to achieve therapeutic benefits. Other factors such as exposure time and frequency also play crucial roles in the effectiveness of RLT, which is why professional advice is important when using red light therapy.”
What Are the Benefits of Red Light Therapy for Eczema?
Red light helps calm inflamed skin. More specifically: “Red light therapy can be an effective way to manage eczema by reducing inflammation, soothing irritation, and supporting the skin's natural healing process,” says Hsu. “Eczema flare-ups are often triggered by an overactive immune response, leading to redness, swelling, and itching. Red light therapy helps calm this response by reducing pro-inflammatory cytokines, which can result in visibly calmer, less irritated skin.” Further, explains the acupuncturist, “It also increases blood flow to affected areas, delivering oxygen and nutrients essential for skin repair, promoting faster healing and relief from discomfort.”
Another major benefit is that red light therapy supports a healthy skin barrier. “Eczema-prone skin often has a compromised barrier, leading to moisture loss and increased sensitivity,” says Hsu. “Red light therapy promotes collagen production and stimulates cellular regeneration, helping to rebuild the outer layer of the skin. This not only locks in moisture but also provides better protection from external irritants, reducing the likelihood of future flare-ups.”
All of this being said, it’s important to note that this treatment isn’t a cure-all, and you should still speak to your dermatologist before determining the best treatment plan. “Red light therapy is definitely not a standalone treatment for eczema, but should be potentially considered as part of a holistic approach,” says Malik.
When Do You See Results of Red Light Therapy for Eczema?
Treatment will vary based on severity and your skin’s response. However, “I typically recommend three to five times a week for 10 minutes per treatment area,” says Malik. “If used consistently, benefits can be seen in four to six weeks.”
Are There Any Risks to Using Red Light Therapy for Eczema?
Red light therapy is generally considered safe and well-tolerated for those with eczema. However, both experts stress the importance of using a proven, FDA-cleared device for wavelength accuracy. “Receiving treatment from a trusted provider guarantees the use of the correct light wavelength and intensity, promoting optimal skin healing and repair,” says Hsu.
The red light is also quite bright, so proper eye protection is required during treatment. “Some patients may be extremely sensitive to the light, particularly if on medications and cause photosensitivity,” says Malik.
