I have combination skin type, from 3 months I have acne on my face. I have consulted dermatologist who suggested me some creams as clindamycin & nicotinamide gel, tretinoin gel, momate creams. I am using these all. But I am not getting overcome from my problem. My thyroid level is normal. In my teen age I never got this type of pimples on my face. My concern is why I am getting acne in this age? Should I do any hormonal testing. If yes, then plz tell the name of test. I m married from 3 years and don't have children, before marriage my average periods was of 5 days, now from 2 years average reduced to 3 days. Is this normal?
