Acne: Apparently your doctor thought that your acne is more severe than you .Both drugs are retinoids but isotrex is a bit stronger.

(Iso)tretinoin: Retin-a is tretinoin (available in states as http://www.Drugs.Com/retin-a.Html) whereas isotrex (appears to be uk brand http://www.Netdoctor.Co.Uk/skin-and-hair/medicines/isotrex-gel.Html) is isotretinoin. When taken orally as a pill (don't eat cream/gel/lotion!), Isotretinoin first gained fame as Accutane (no longer sold in states under that brand).
