Hi- I can enthusiastically endorse the Mixto SX laser to you- I have had one in my practice for almost a year, and have treated a large number of patients now. It provides a significant improvement in acne scars, wrinkles, and sun damage, with a single treatment, a very reasonable and comfortable recovery, and a very low level of risk. The details of the recovery period will depend to a large extent on the indications for the procedure (treating deeper wrinkles and acne scars requires stronger settings and therefore will involve a slightly longer recovery)- but when I say the recovery is longer when the procedure is done for these problems, I mean it is maybe a day longer (not too bad). As for pain, the level of discomfort associated with the treatment itself also depends on the settings used, but most patients don't require more than a bit of numbing cream and maybe a small dose of valium if you are anxious. Pain after the procedure is usually no more than you would expect from a sunburn and Tylenol is adequate to keep you comfortable.
