dazzed 219 Share Posted February 26, 2020 (edited) Different wavelengths, different penetration. C02 laser is always ablative, meaning it removes skin and causes bleeding. With erbium, if I remember correctly it can be ablative or non-ablative. Ablative erbium removes skin but does not cause tissue contraction like co2 laser. Generally, erbium is considered safer for ethnic skin because it doesn't cause as much aggressive hyperpigmentation. Edited February 26, 2020 by dazzed Quote Link to post Share on other sites
