I've not used DDF products but have battled with severe acne for years and that's what I suggest..If you are dealing with what's called mild acne or occasional break-outs like around the time of the month, then such products may come handy..but if you're suffering from severe acne, then go see your derma at the first opportunity and let him treat your acne because severe acne wouldn't go away without prescription medicine and topical antibiotic...
I think you may know this already as I recall you mentioning in one my threads that your sister used Tazorac, which I was put on too along with accutane, and that she has the most gorgeous skin now...but I just wanted to give a heads up for others who may not know this already...
Sorry, didn't mean to derail your thread!
