anything i have used never works. im sooo allergic to it that nothing the doctor gives me seems to help. so, all i do is scatch it lightly, just enough to open the pores, then put on some benadryl or acohol. do this about 2 days and twice a day. works and goes away in about 3 days. y spend lots of money if nothing they give works...(waste) i always would take a huge list of stuff that doesn't work that they already gave me, just to show them they are nutz.
