Ablative laser resurfacing, with CO2 or Er: YAG lasers, has been shown to be effective for traumatic and surgical scars, especially when resurfaced within 6 to 10 weeks after trauma or surgery or even immediately after surgery.

 CO2 laser is a powerful laser that penetrates deeply into the skin and is better at removing thicker and deeper scars. As a consequence, recovery time is long, usually about two weeks. The procedure also can be painful. Erbium: YAG laser is less powerful than the CO2 laser and is most often used to treat shallow scars.
