I've had 4 sessions using the picosure laser for removal. There are different lasers, two at least, I believe different colors work best with different lasers. For example, the pico laser has been removing the red color the slowest for me. Even so, my tattoo is very faded, and there has been no scarring at all. It does hurt, but I read an article recently that there is a new patch that you can cover the tattoo with before lasering..... supposedly the laser still goes through and does its thing, without the pain and reducing/preventing scarring for those who are prone to that. Due to pregnancy I can't get treatments for a while, but I think 2-3 more sessions will have it virtually gone.
