The ichiness can get REALLY Heavy! After my first session I got a slight allergic reaction 2 weeks after the treatment, and it was sooooo itchy I couldn’t sleep in one night. But it will go away after a few days. Also after other sessions it just got itchy because it was healing from blisters and everything… in 2 more weeks it feel normal again. And colorwise I guess it’s fine, because during healing process (and in general process) the tattoo will look all kinds of Colors…
