A recent study published in JAMA Dermatology has demonstrated that at-home light-emitting diode (LED) devices are both safe and effective for treating mild to moderate acne. The research, conducted by Sherry Ershadi and Dr. John S. Barbieri from Brigham and Women’s Hospital in Boston, analyzed data from six studies involving 216 participants aged between 12 and 50 years.
The findings revealed significant improvements in acne lesions among users of LED devices. Specifically, there was a 45.3% reduction in inflammatory lesions and a 47.7% decrease in non-inflammatory lesions. Additionally, the Investigator Global Assessment, a scale measuring acne severity, showed a 45.7% improvement. These benefits were observed after a usage period ranging from four to 12 weeks.
The study assessed various LED devices, including those emitting red, blue, and combination wavelengths, all of which proved effective. Importantly, no severe adverse reactions were reported. However, some participants experienced mild side effects such as dryness, redness, or discomfort during the light therapy sessions.
The researchers concluded that at-home LED devices, especially those combining red and blue light wavelengths, offer a promising adjunct to existing over-the-counter and prescription acne treatments.
