Small tiny pimples with pus on face.

I always have small tiny pimples with pus on my face, sometimes its itchy..i used mometasone &fusidic acid combination for the past 2 years like once a week on the pimple site only (like dot dot)...when i used this ointment its gone...but after 5 to 7 days it comes back again...most common site is around my jaw line,my forehead and under my eyes...i don't know what to do,i know that mometasone is a steroid cream and not to use on regular basis or for a long term,so sometimes i use salicyclic or clindamycin or any pimple/acne ointment to replace it,results not good as mometasone...what i want the most is to cure this tiny pimple with pus from coming back again and again...to take an average i have this tiny pimples once every week...Can you please help me with my problems?
