One of the most commercially successful applications of LED light therapy is its use for hair growth.
LED treatment is effective for treating burns -- decreasing symptoms of burning, redness, swelling, and peeling.
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).
Red LED therapy is effective for skin rejuvenation. It improves skin complexion, collagen production, skin roughness, and wrinkle status.
