this is a numbing cream available by prescription only, has to be made at a compounding pharmacy. used a few yrs ago while having cosmetic procedures on face. have moved to a small town since then. got new script as a favor from my regular dr so i can get laser hair removal. the only compounding pharmacist in this entire area said he needs specifics on the ingrediants, etc. so he can make it up for me. benz/lido/tetra 20/8/4 gel. info greatly appreciated.
