Hi just had second treatment on hands with ipl. Doctor said he was disappointed with results of first treatment. Spots darkened but never faded. He said he used max strength and same on second.The spots have gone slightly darker again day after treatment,but i now dont hold up hope for good outcome and the doctor said he wouldnt normally do more than 2 treatments.He said he would consider a chemical peel. All the web sites discussing this treatment say it takes 3 or 4 treatments for improvement, what are my options?
