Had it done because I hated the line across my forehead. Well, I sure did get rid of it, it looks great. But needless to say I dont look like me. My eye swelled so much the upper lids. its been 5 weeks and it hardley changed. And one eye looks bigger then the other. I Would not do it again. If there was a way to check if you were allergic I would certainly consider it before poking.
