LED photorejuvenation is an infrared light therapy used to slow the signs of aging and treat blemishes, including scars and sun spots. LED photorejuvenation systems are said to help boost collagen and elastin production to make skin smoother and firmer. They are also believed to promote healing of wounds and bruises, and may even provide relief from minor pain. LED light therapy is considered far gentler than chemical peeling, laser resurfacing, dermabrasion, and other skin rejuvenation procedures. Home photorejuvenation lamps are available, and considered safe for daily use on all types of skin.
The infrared lights used in LED photorejuvenation can penetrate up to 1.5 inches (4 cm) below the skin's surface. This is believed to make it effective not only for stimulating increased collagen and elastin in the skin, but for speeding the healing of injured bones, ligaments, and muscles. Boosting collagen and elastin production can firm the skin, and can help reduce the appearance of fine lines and wrinkles.
The LED lights are also believed to increase blood flow to treatment area, which can help speed the healing of bruises, cuts, and sprains. LED light therapy is believed to provide pain relief for minor injuries in muscles and joints. It may help relax tense or spasming muscles, and it's been used to ease the symptoms of arthritis and psoriasis.
LED light therapy, whether used for cosmetic or medicinal purposes, usually gives the best results when treatments are repeated. Persons seeking LED photorejuvenation therapy in a professional setting are often advised to receive five to ten treatment sessions in a row, repeated several times over the course of a year. Home LED photorejuvenation kits are available, and can be used safely on a daily basis. Persons using home LED light therapy kits are advised to treat the area daily, or twice a day, for four to ten weeks. Afterward, maintenance therapy sessions can be performed two to three times weekly. The length of time necessary for each treatment session can vary widely, depending on the type and construction of the home-use photorejuvenation lamp used.
