Hello. I have an unusual situation. I'm removing all of my tattoos. 3 of my tattoos unfortunately don't respond to laser, since my artist mixed something in with the ink. I know that the small one could be removed via surgical excision, but I have a question/ inquire about the other two, that are semi-large. I have read that a tissue expander has been successfully used for larger tattoos and was wondering if it could be used in my case as well.
