Acne is a chronic inflammatory disease of the sebaceous glands of the hair follicles. It may be related to high androgen levels, excessive secretion of sebum by the sebaceous glands, acne rods infection, and abnormal keratinization of the ducts of the sebaceous glands of the hair follicles. If you have a lot of acne, you can take oral retinoids if they are not contraindicated. If it is not very much, you can use salicylic acid or fruit acid treatment, topical retinoids, or acne needles to get rid of it. In short, it is a combination of treatments.
