Sir, I am Dr.Deepthi, i have been suffering from acne for the past 6 months, i am a known case of PCOS, my dermatologist has put me on azifast 500mg for 8 weeks, Aldactone 150mg, T.Yasmin, T.Sotret 20mg, i had also got 4 salicylic acid peels done, though my acne has come under control and i am having only fewer breakouts, i hav PIH on my cheeks... i hav been given Demelan for it... but i hav noticed not too much difference with it ( been usin it for 2 months now) and also i was wondering if it would cause hyper pigmentation because i noticed a small patch on my face which has become a little dark( not from PIH), kindly address my queries...thank you.
