I did one arm with one layer of 30% and the other arm with 2 layers. This photo is of the arm with one layer. It started to peel first. As you can see where I have peeled it is very pink where I have not peeled very dark brown almost purple. The rest of my arm is brown from the sun damage in the TCA. This gives one a sense of what to expect from the TCA. Once the pink skin heals I should be free of the sun damage if not I will do another layer, but I can see most of it is gone. The pink new skin is so smooth like a baby's butt. the new area is small but it is the area on my upper arm HTH someone else
