Er:YAG laser showed a decrease of 51.3% in redness, 50% in elevation, and 48.9% in hardness of keloids in one study after treating 21 keloids. The recurrence rate was not reported. [92]

Similar to the carbon dioxide laser, the argon 488-nm laser can induce collagen shrinkage via generation of excessive localized heat. The argon laser has demonstrated recurrence rates of 45-93%.
