dazzed 200 Posted February 26 (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.
