I dont think we're allowed to mention websites on here.Just look for it in a search engine.As for a oral antibiotic ive been on doxycycline for about 9 months now.I use differin at night,and wash my face with carleys clear and smooth in the morning.My face is totally clear for now,has been for about 2 months.Any stray pimples that might pop up i zap with my thermaclear device.At one time i used to get those big pimples that form under the skin but never come to a head.Since using the differn gel and doxy ,i might get a small pimple once or twice every couple months.Hope this helps.Good luck ,God bless.:)
