Picosure on Two Dense Black Tattoos

I made this huge mistake starting from the age of 18 when i did the first tattoo on my left arm. Since the beginning i decide to start tattoing myself because i develop big stretch marks on my body especially on my arms, thus i thought that these would have been my only hope to make them disappear. The big dense black samoan tattoo on my left arm is a cover up of tribal and is very recent (about 6 months ago) and you can see that is a real mess, the other tattoo with the sun it's not a cover up, but as the first was made to hide stretch marks. Well, let's say that stretch marks are much less visible, but as soon as i realized that stretch marks were no longer a problem, tattoos have become. Now i'm 26, i'm an Engineer and i don't think this ink describe myself , so i want to get rid of it . I'm italian and i live in Milan, two months ago i started looking for information about the process of tattoo removal and i found this fantastic forum, then i realized that i would have preferred only the best technology available so i search for a picosure clinic near my place. Before starting the picosure treatments i made one treatment with the qswitched alex trivantage , then i found a doctor with a picosure laser 15 minutes by car from my place and i decided to start this long process. I know that it will be very expensive and stressful but i want this complete mess removed. Need some hope from you guys.

First session done.
To anyone says that is not painful, total [RS bleep], it’s painful as fuc*, i did 45 minutes of non stop lasering with no anesthetic, the doctor was able in one single session to made both the tattoos, and i was very hurted at the end, and i think i can tolerate pain very well.
I did this session three weeks ago and to be honest i don't know how to judge the results, the tattoo with the sun has faded quite a lot on the lower part (especially on the dices) with different lines almost broken , while the other one looks like the same, maybe because it’s very recent and it contains a very dense ink so it will probably take more time.
Another thing i want to warn you about is hypo pigmentation, i have brown skin and on the sun and the dices i see some lost of pigment, i've already called the doctor and he told me is normal and that the pigment will come back within few weeks (for real??)
Sometimes i just think about it and if it worth or not, spend thousand of euro with no warranty of success. Not only this, sometimes i even think that is a matter of accepting myself , but to be honest in a world where the appearance is so relevant i want these to be removed.

These pictures are a little bit brighter than the other one. As i said, the one with the sun has faded very well, while the other one (samoan) it looks almost same. Next week i'm going for a new session.
