Does Pixel Treat Leg Scars and Keloids?

The Pixel which is a fractionated Erbium laser would not be effective for keloids. Lasers such as CO2 and pulsed dye, have been shown to be effective. If you have failed more conservative (and probably at least as effective) treatment such as steroid injections, cryotherapy, 5- FU, intralesional Bleomycin, you might look into lasers as an option.

Keloids have a genetic component wherein the body does not recognize the endpoint or plateau phase of collagen deposition in wound healing. The optimal treatments remain keloid tissue compression and injection of corticosteroids intralesionally.
