Im a surgery resident. Im having acnes since 12 th grade . I have acnes on face chest and back. In face i most have papular acnes and in back admist papular acnes some pustular acnes erupt once in two weeks. I dont have dandruff. For maintanence im using keto+salicylic acid shampoo once in two weeks along with my shampoo. I dont apply oil. For face im using 2 percent salicylic acid face wash and clinda adapalene combo gel...and for back i use benzoly peroxide 3.5 percent but still i dont get rid of them completey and i get flare ups(pustular stage 3 acnes).i bought adapalene 10 percent for hyperpigments acne scars in back but as new acnes develop i m still using benzyl peroxide. Is there any other promising treatment and prevention options available to prevent recurrence. what would be best for hypigmented acne scars on my back.
