LED therapy is a skin care treatment that uses light-emitting diodes (LEDs) of various colors, normally red, blue, and infrared, to maintain healthy skin. LEDs produce a low-powered glowing light, which is positioned to shine onto the face or other area being treated. No heat is produced by the LEDs, and it should not be confused with laser therapy. The skin benefits of different colors of LED light have been identified through a broad array of studies. The most often cited study is the Whelan study, published in 2001 by NASA’s Marshall Space Flight Center, which found that LED light helped speed up wound healing. Red light is most often used for general skin improvement and to reduce the visible signs of aging. Blue light has been shown to destroy acne bacteria. Infrared light may have beneficial effects on the skin’s natural supply of collagen and elastin, which are responsible for maintaining skin firmness and resilience. A series of regular treatments will provide the best results. What Can I Expect? No special preparation is necessary. Simply arrive to your appointment on time, relax, and enjoy the treatment. Your skin care professional will cleanse your skin and may also apply a serum or other facial products to enhance the benefits of your session, depending on your goals and the range of treatments offered. The LED device will be positioned on your skin, or up to a few inches away. Your eyes will be covered so that the light does not bother you. Relax and rest while the glow of the LEDs bathes your skin. Typically, no sensation is felt. Some people may feel a slight tingling, or see flashes in their vision temporarily as a result of having a light source close to their face. Keeping your eyes closed and covered during the treatment will help avoid this.
