Blackheads, also known as blackhead pimples, are a mild form of acne, and treatment includes keeping the face clean, adjusting lifestyle, and topical medication. Blackheads and pimples are caused by the accumulation of sebum and keratin plugs at the mouth of hair follicles, which form lipid plugs and turn black after being oxidized. Choose water or suitable cleansing products to remove excess oil, dander, and bacterial mixtures from the skin surface, pay attention to oil control and moisturizing, and keep the face clean, which can reduce the occurrence of acne. Limiting the intake of high glycemic index foods and milk, keeping the bowels clear and avoiding late nights can reduce the occurrence of acne. For mild acne, topical medications can be used, commonly including retinoids (retinoic acid cream), azelaic acid, etc., to avoid hyperkeratinization of the skin and reduce the inflammatory response. When acne occurs, it is recommended to seek timely medical treatment, standardized treatment, and medication should be used under the guidance of a medical professional.
