Can at-home red-light therapy really cure acne?
Red-light therapy has emerged as a major beauty trend in the last couple of years, with fans touting its ability to give their face a youthful, blemish-free glow. The treatment uses low levels of red light to penetrate deep into the skin to stimulate the production of collagen, reduce redness and inflammation, lessen the appearance of fine lines and wrinkles, and promote wound healing – all of which helps combat acne.
The treatment can be done in a doctor’s office, where advanced technology is available, but the ease and convenience of red-light therapy devices that can be used at home have made them explode into the market. However, not all dermatologists agree that at-home red-light therapy is effective for acne.
A new study published recently found that using at-home red and/or blue LED devices led to a 45.3% reduction in acne among 216 participants with mild to moderate acne. The study’s authors believe that these devices can be most effective as part of a broader acne-fighting strategy rather than standalone use.
Dr. Raman Madan, chief of dermatology and director of cosmetic dermatology for Northwell Health, recommends red-light therapy to patients who want a nonpharmaceutical intervention for their acne. He suggests that at-home LED devices, particularly those that combine red and blue light, are efficacious for acne and can complement other over-the-counter and prescription treatments.
Red-light therapy is considered generally safe to use, but it’s essential to consult with your medical provider if you have any underlying medical conditions that might affect its effects. Additionally, when buying a red-light therapy device, make sure it is FDA-cleared and from a reputable company.
“I recommend red-light therapy to patients who do not want to take medications,” Dr. Madan said. “We have great treatments for acne, but a lot of the pills can cause some side effects.”
While the study’s results are promising, Dr. Madan believes that consumers should not expect miracles when purchasing at-home red-light therapy products to treat their acne. “I think it is an option for patients, but they should not expect miracles,” he said.
