sorry but i would just say stick with the docs ..
i have tried a few different things before i saw an improvement
i used a cream once a few years ago that sort of burned the top layers of my skin ,it all peeled and my face was bright red .yet i still had all the acne still ..my sister used exactly the same ointment and had fantastic results .
i was refered to a dermatoligist too at one point and he told me my skin wasnt bad enough
(yeah thanks dermo man)
at the moment i am using a topical solution called zineryt and its fantastic (for me)
i have been using this for a few years now , i have to use it every day for 6 months even if my skin clears up during this time ..and then go back the docs ..
although im not always a good girl , i was at first ,whereas now ,i use it till my skin clears ,then usually go back when it flairs up again ! (latley its more frequent)
regular cleanse tone and moisurise ..as soon as i stop this my skin flares again..i also use dove exfoliating soap.
its just a matter of perseverence and finding the right course of treatment..
