hi, Acne vulgaris is a common chronic skin disease involving blockage and/or inflammation of pilosebaceous units (hair follicles and their accompanying sebaceous gland). Diet therapy, such as a low-glycemic diet and avoidance of “junk foods,” has been suggested as a nonpharmacologic measure to manage acne vulgaris. Procedural treatments for acne vulgaris include the following: Manual extraction of comedones Intralesional steroid injections Superficial peels that use glycolic or salicylic acid Benzoyl peroxide is generally safe and effective apply locally twice daily. take cap minocycline 100 mg once daily. acne scar needs procedure to correct it. dermaroller and laser are effective. hope this will help you. thanks
