Acne on the breasts should be treated by cleansing the skin on the surface of the breasts and also through the use of medications and other methods. Acne is a mild form of acne that occurs on the face, but can also occur on the chest and back. For the treatment of acne on breasts, medications such as retinoic acid gel and adapalene gel can be used to help dissolve and expel acne, benzoyl peroxide gel can be used to kill Propionibacterium acnes and dissolve acne, and medications such as azelaic acid ointment and selenium disulfide lotion can be used. In addition, acne on breasts can be treated by using special acne squeezers to squeeze out the contents. Since the onset of acne is associated with abnormal keratinization of the sebaceous gland ducts of the hair follicles, it can also be treated by using fruit acids to accelerate the exfoliation and renewal of the epidermal cells and to reduce the adhesion of the keratin-forming cells. If acne develops on the breasts, it is recommended to seek medical attention and follow the doctor’s instructions.
