Co2 lasers are great for resurfacing skin or remodeling scars. The laser that you mention (The Sharplan ) has been a very effective and reliable device, we have one we still use on occasion in our office. newer CO2 lasers, however, offer safer more effective treatments usually with less healing time.
For certain types of scars, including surgical scars, burn scars, traumatic scars or acne scars, the Lumenis Ultrapulse CO2 is now the gold standard. This laser can be used as a fully ablative CO2 or used in a fractionated mode (Total FX) to provide safer treatments with less healing time. I often use the Fractionated laser on acne scars or surgical scars because it has an amazing ability to remodel skin [blur scars, fill in depressed scars and sometimes even helps to reduce the lighter color some scars have].
So, to answer your question, it is very likely that your skin would respond well to the fractionated CO2 lasers with less concern for any negative effect from your previous laser treatments. Definitely look into this possibility.
Good Luck
