Red light therapy uses very low levels of heat and doesn’t hurt or burn the skin. It’s not the same type of light used in tanning booths, and it doesn’t expose your skin to damaging UV rays.
What Does It Treat?
Researchers have known about red light therapy for a while. But there aren’t a lot of studies on it, and they don’t know if it’s better than other types of treatment used to help you heal. Red light therapy may help with:
Dementia. -----In one small study, people with dementia who got regular near-infrared light therapy on their heads and through their noses for 12 weeks had better memories, slept better, and were angry less often.
Dental pain.----- In another small study, people with temporomandibular dysfunction syndrome (TMD) had less pain, clicking, and jaw tenderness after red light therapy.
Hair loss----. One study found that men and women with androgenetic alopecia (a genetic disorder that causes hair loss) who used an at-home RLT device for 24 weeks grew thicker hair. People in the study who used a fake RLT device didn’t get the same results.
Osteoarthritis.---- One study found red and infrared light therapy cut osteoarthritis-related pain by more than 50%.
Tendinitis----. A very small study of 7 people suggests RLT lessens inflammation and pain in people with Achilles tendinitis.
Wrinkles and other signs of skin aging and skin damage-----. Research shows RLT may smooth your skin and help with wrinkles. RLT also helps with acne scars, burns, and signs of UV sun damage.
