LED light therapy (LLT, Low Level Light Therapy) can be used as a stand-alone treatment to suppress active acne and to rejuvenate the skin, treating fine lines and wrinkles. It is also effective in treating muscle pain, joint pain and arthritis. In addition to this, it is used in combination with other skin treatments (such as post-surgery and post laser) to reduce bruising, pain and swelling, and to promote faster wound healing ultimately producing better results.
