I still Have 2more session tho so far, my tattoo doesn't change at all. I assume 1st and 4th session laser was light, cuz I asked its way too hurt after 3rd session. Should I ask to go back as same level of laser as 2nd and 3rd time? It doesn't necessary to be all gone but if it doesn't change even after 6times session, I just want them to pay me back my pain and money...
