Unlike adolescent acne, most adult acne is caused by stress. The autonomic nervous system and endocrine system are disrupted, disrupting various balances in the body. In addition to dryness, irritation from UV rays, and excessive secretion of sebum, dead skin cells often thicken and form lumps called keratin plugs, blocking pores and causing acne. Typical adult acne occurs on the cheeks and face lines, which tend to be dry. At our clinic, we analyze hormone levels in the blood to determine the underlying cause of acne in the body. Our clinic not only provides external treatments such as light therapy, lasers, and peeling, but also aims for a radical cure from the inside of the body, such as injections, intravenous drips, oral medications, and nutritional guidance.
