LED treatment is effective for treating burns -- decreasing symptoms of burning, redness, swelling, and peeling.
Green light is effective in treating skin conditions involving redness, swelling, and other effects related to pigmentation.
Blue and red light are synergistic in treating acne due to their anti-bacterial and anti-inflammatory effects. LED therapy is safe and has fewer side effects compared to other treatments (e.g. topical or oral medications).
