Hi doctor. My name is kevin. from the start: Since the mid october 2015 I have been using No Scar cream (Hydroquinone     I.P.     2%w/w Tretinoin     B.P.     0.025%w/w Mometasone     I.P.     0.10%w/w In a cream base q.s.) for a couple of months which gave me results in reducing my acne and pimple scars. later I discontinued for a month and then continued it again for a month. In late december I developed prickly heat like bumps on my fore head due which i visited a dermatologist. He started with Cutisoft (Hydrocortisone Acetate Cream BP 1% w/w) for the first 20 days, then Deriva CMS gel ( next 20 days),then Tretenoin 0.025% (next 20 days), then microbenz 3.5% (next 20 days). He said i had an allergy. Moreover I have been having Doxol 100 for this entire treatment. I wash my face every 3 hr with Clean and clear face wash. Nothing seems to be working. Those small bumps grew up into pimples with a spread on all over my face. The old one subsides and there are new once coming up. One more thing to mention is that ive been treated for my stomach upset (which the doctor suspects to be an infection for a couple of times during this period. I had been passing motion for 3-4 times a day with a lot of gas) for a couple of times during this period. Please suggest is there any thing to worry. What could be going wrong and how to i correct it.
