There are so many different colors of light therapy, and it's likely that you'll want to use a variety to target different problems. If your specific skin woe is discoloration, hyper-pigmentation or dark spots, green light therapy is a great place to start.
According to Dr. Müller, green light targets "melanocytes, melanin-producing cells located in the bottom layer of the skin’s epidermis. It inhibits the production of excess melanin, prevents it from traveling to the skin’s surface, and breaks up melanin clusters to lessen existing discoloration."

The patented design includes a combination of 100 LED lights in red mode and 62 LED lights in blue mode working together to smooth wrinkles, firm skin, diminish discoloration and clear acne for a beautiful, youthful complexion. You can choose from three light treatment options—red light therapy, blue light therapy or red and blue light therapy. The red lights stimulate the natural production of collagen and elastin to reduce wrinkles, sun spots, sun damage and redness; blue lights help destroy P. acnes bacteria and prevent future breakouts; and the dual red and blue lights target wrinkles and acne at the same time.
