Detailed Description:
Light would be efficacious in improving scar appearance due to its known effects on wound healing, acne, and its use for skin rejuvenation. Light interacts with cells and stimulates the production of new collagen and elastin. This same energy can be used to inhibit collagen formation and help improve scars.
