Hello. Thanks for writing to us at healthcaremagic For acne I would suggest that you a topical antiacne gel e.g either clindamyicn or benzoyl peroxide gel during day At night you may use a topical retinoid e.g Adapalene gel. I would suggest that you visit a dermatologist in your vicinity for the needful. Your doctor may also start you on oral antibiotics like azithromycin or doxycycline if you have inflammatory acne. For post acne marks, you may use kojic acid cream; it is a useful skin lightening ingredient for post acne marks. Your treating dermatologist will tell you more about it I would suggest a gentle cleanser for face wash e.g cetaphil cleansing lotion, twice daily. The white spots are likely due to Pityriasis alba, which is localized light colored patch of dry skin. You may use an OTC topical steroid e.g cortisone cream, twice daily just over the hypopigmented patch. Regards
