Peels always get a bad rap among people. We always tend to forget that they have been around for more than 3000 years. The Pharaos used them. We tend to think of lasers these days, but peels have been tried, tested and do work.
I always recommend regular peels, because I tell my patients...
50% TCA is notoriously unpredictable and may scar. Lower percentages of TCA are much safer. Arms can be nicely improved using lower strengths of TCA artfully applied by a well trained peeling expert such as a dermatologist. See link below
Recover is on average 3 days to 1 week. But you should discuss this with the peeling doctor in detail so you are not un informed. Be careful out there.
