Thermage is a fabulous laser to tighten the skin, especially the lower face and jowls. You should leave with no down time and minimal discomfort. I have not seen any patients look different as you say 20 days later. Please return to your treating physician for examination and of course you may post your before and after photos here. For the best cosmetic results please consult a board certified dermatologist with a great deal of experience with Thermage.
