Hi there Rashmi. Firstly you are newly married so relax..these things have a hormonal
background to their pathology & as such there are bound to be fluctuations. Add to that stresss & change of environment & you have enough reasons for the potential flare-up. Second, are you on any oral contraceptives & have you done any pregnancy
test & if negative, are you planing for a baby soon? Based on all this & viewing your lesions (please upload photographs), only then can a dermatologist
give you a more honest picture & a concrete managment plan ...either local treatment or systemic but that again will vary on the cost factor, side effects, expectation & type/grade of acne. As for the acne pigmentation/marks, you may try to apply a 2% hydroquinone
cream on the 'spots' for starters & then may upgrade to 4% & this of course is provided you dont have an allergy
to these creams. But as i said at the outset, this has to be visualised & hence best to fix an appointment with a dermatologist nearest you. Cheers & Good luck!
