Annoying isn't it.
I have suffered acne since early teens. took the pill throughout most of my adult life, Dianette being the wonder pill. Even when the GP refused to prescribe it for me due to a blood disorder I bought it over the counter on my trips to Spain rather than suffer spotty face, neck, back, chest.
It was never cystic acne, but a lot of spots.
However in Jan this year I stopped taking it andwent to GP for a referral to Dermatology. typically when I went the spots weren't that bad. I think I have 'grown out' of it, a bit. Still very oily. Also my diet is 100% better than it used to be. And I don't smoke now. So maybe that helped?
Anyway - the Dermatologist was quite helpful. He prescribed me Differin Gel to use for awhile in the first instance. Very good. It basically increases cel turnover, prventing blockagesin the pores. He did say that if I was still not totally happy then to go to the GP and ask for Trimethoprim anti biotics. He said that these give the best results in all anti biotics. And if they don't work then he prescribes Roaccutane.
so I have been taking the anti bs for a month or so now, and using the Differin gel each evening. And all is well. Still get the very occasinal small pimple, but not the big hard welts that take three weeks to go away.
My opinion is that if you have true acne, any cosmetic product won't touch it.
p.s. The Differin Gel makes my skin look much better in general tone too, saves on the acid peel stuff :)
