I had my third laser tattoo removal treatment 4 weeks ago and it blistered and scabbed much more than previously. I have tried to keep it dry and not interfere with it as much as possible - although not getting it wet has been hard due to it being on my hand. It now looks raised and red and if it is forming scars. I can't imagine it will be ready to re treat in just two weeks. What is happening ? Has this gone wrong?? Please kindly advise/help....
