Hi, Thanks for writing to us. Firstly you need to treat your active acne lesions. For the same, you may need topical antiacne creams (like adapalene, tretinoin, clindamycin or benzoyl peroxide) or/and oral antiacne medicine like azithromycin/minocycline/doxycycline/ isotretinoin depending upon severity of lesions. If lesions are just few and mild, you may use an antiacne soap(acnelak/d acne/dermadew acne) and apply a topical gel like epiduo gel once in night. Once acne lesions are gone, use a good sunscreen in morning and azelaic acid 20 percent cream in night to reduce marks. Hope this helped. Take care
