In an article published in Yahoo Life, dermatologists detailed the increasingly popular and noninvasive red-light therapy and whether the treatment is effective for various skin conditions. Dermatologists noted that the technology works by producing wavelengths of light through light emitting diodes (LEDs), which are then directed toward the skin to increase the processes of restoration and repair. They noted that the benefits of red-light therapy may be wide-ranging—including increased circulation and collagen production, as well as decreased redness and inflammation—and may alleviate acne, hyperpigmentation, psoriasis, hair loss, fine lines, and wrinkles. However, evidence for the consistency of these benefits is dependent on a few small studies and is not yet extensively proven. In addition, although red-light therapy is known to be safe, individuals may experience mild symptoms such as headaches or dizziness, and long-term exposure without the use of protective goggles can cause eye damage.
For individuals who have a history of eye disorders or seizures; conditions such as lupus; open lesions; or who are on photosensitizing medications such as tetracycline, doxycycline, hydrochlorothiazide, or naproxen, dermatologists recommended avoiding the treatment. For those who decide to proceed with red-light therapy, individuals may visit a dermatologist for a more powerful dose of the treatment or purchase a less powerful mask or wand to use at home. Dermatologists stressed the importance of looking for the U.S. Food and Drug Administration approval label on the packaging of at-home options. When undergoing each session, they suggested cleansing the face prior to using the red-light therapy, applying an antioxidant serum after each use, and conducting each session for 20 to 30 minutes two or three times weekly for masks and 10 to 20 minutes three to five times weekly for wands. Despite the promising results of red-light therapy, those with aggressive acne, skin disease, or more severe hair loss were urged to visit a dermatologist rather than attempting to treat the conditions at home.
