I am thinking of having smart dot laser can you tell me if this will be the same as erbium laser. I have fair skin and wrinkles above my lips and around the eye area I want to improve. I want to no if this is done more aggressive what that entails and would I need more than I week from public. And how bad I will look, I have seen a couple of videos on this site of a full face were it is co2 laser but no mention to how deep there treatment was. Also can I get colour change in the aggressive area?
