Hello. Thanks for writing to us at healthcaremagic Acne can involve the face as well as back and chest, as all these areas are rich in sebaceous glands. Acne involving the torso is more stubborn and slow to respond as compared to acne affecting face. It may recur. Diet, specially high calorie foods may have a role in flaring acne but it is not consistent in all the patients. I usually don t advice any dietary restrictions in my patients of acne. I usually recommend Oral treatment with Retinoids in my patients of acne involving torso. I also combine an Oral antibiotic e.g azithromycin along with retinoids for faster improvements. Topical benzoyl peroxide gel or body wash forms an important part of treatment along with Oral treatment in my patients of acne on torso. These are all prescription products. I would suggest that you visit your dermatologist. Your dermatologist will assess the severity of your acne and advice accordingly. Regards
