Depending on your age and the amount of skin laxity there are different things that can be done. I would be wary of doing another CO2 laser treatment although the fractional CO2 lasers safer to use in my experience. If there is a slight "crepiness", then a superficial laser resurfacing may be in order but make sure that the physician treating you has experience in this area. The same goes for removal of excess skin. As one of the other commenters stated, removal of too much skin can cause lower eyelid retraction where the white part of the below the iris is exposed. As one of my professors once told me, sometimes the opposite of "good" is "better" and you can open up a whole can of worms turning a small problem into a major one.
