A TCA peel on you upper arm is likely not to affect the tatto at all. If a TCA peel is done on your are your are very likely to develop deep scarring. I would never suggest a TCA peel on this area for any purpose.
I have a red and black tattoo on my left upper arm and I read somewhere that TCA Peel will effectively remove or fade the tattoo. I need to know if it will, what concentration I will need, and how much I can expect to spend.
