You say that you have had 5 TCA peels with little result. Clearly these are not being done by a physician. These are probably low concentration TCA. The 35% TCA gets dramatic results but is a medium depth peel with significant peeling. So by all means if you have 3 treatments left and want more dramatic results you need to discuss with your DOCTOR what would be the next best treatment for you. More aggressive TCA v Fraxel v other resurfacing lasers. Please note that Fraxel is a brand name and under that name there are at least 3 different types of Fraxel lasers all with a subname like "repair" , "restore" etc . They are not created equal, do not have same results, do not have same downtime, do not have same risks... SO do your research and speak with your doctor and please be sure they are skin experts .
