Full Sleeve Tattoo Removal - Austria

I am removing many tattoos on my left arm. i keep just some of my cryptic tattoos and the rest will be removed completely. I habe noticed that the skin looks brownish where the background was removed and i am wondering if my skin will be like before the tattoo or if a shadow will stay. i have an appointment every month so that they can always treat another area of my arm.. the light blue colors were gone after one session.. the background was also gone in one session

the first fotos will be bofore i had any laser treatment, the fotos after will be like this:

U.F.O : 2 times
statue of liberty : 2 times
waves : each side one time
lettering : one time
background beside U.F.O. : one time

i will keep the diamond

Here are some before after pictures..

after one session except U.F.O., writing and statue of liberty

The statue has even faded more and i cant wait for my next treatment.. im hoping that the statue is gone in some months!

The brown shadows will dissolve over time as this portrays burning or scarring and have not much ink left inside the tissue
