SKIN HELP PLEASE!!!!?

BASICALLY I TURNED 20 ON THE 19TH OF JUNE AND UNFORTUNATELY I STARTED USING ''TRIADCORTYL' CREAM AT THE AGE OF ABOUT 16 BUT VERY RARELY AND ONCE THIS CREAM HAD BEEN BANNED I STARTED USING THE CREAM DERMOVATE AT THE AGE OF 17 I USED IS JUST TO GET RID OF SPOTS BUT UNFORTUNATELY THE MORE U USE THE STEROID THE MORE U NEED TO BE EFFECTIVE. I CONTINUED USING THIS FOR ABOUT A YEAR AND A HALF APPLYING EVERY TWO DAYS CONSTANTLY BEFORE I WENT TO BED. I THOUGHT ENOUGH IS ENOUGH AND DECIDED TO GO TO THE DOCTORS WHERE THEY WERE SHOCKED!!! TO FIND I USED SUCH A POTENT CREAM ON MY FACE (SEEING AS IT CAN CAUSE ME TO AGE QUICKLY, THIN SKIN ETC ETC) SO THEY SUGGESTED I STOP AND TRY SOMETHING ELSE ALL THE OTHER THINGS THEY GAVE DIDNT WORK (BETNOVATE, AZELAYIC ACID, EUMOVATE, HYDROCORTISONE) GUESS THEIR NOT STRONG ENOUGH. SO I RELAPSED BACK TO MY DERMOVATE AND MY FACE WENT BACK TO NORMAL. SO THE MAIN POINT IS WHENEVER I STOP USING DERMOVATE WITHIN 3 DAYS I START GETTING REALLY ITCHY AND GET A BAD RASH THAT MAKES ME LOOK LIKE A LITTLE MONSTER. I HAVE FINALLY! STOPPED ITS BEEN 5 DAYS NOW AND I LOOK AWFUL EVEN MY MUM POINTED OUT. SO I WAS JUST WONDERING HOW LONG DO YOU THINK MY SKIN WILL RETURN BACK TO NORMAL SEEING AS IS HAS BEEN SO DEPENDANT OR DERMOVATE OR IS THERE JUST NO HOPE FOR MY FACE. (PS I AM BLACK BUT SORT OF LIGHTSKINNED AND UNFORTUNATELY ABOUT A YEAR AGO I STARTED GETTING BLACK DOTS ON MY SKIN(PIGMENTATION OR SOMETHING)) SORRY FOR THE LONG WINDED ESSAY :D
