Development of acne
Development of acne, cut through epidermis and dermis with hair and sebaceous glands. The illustration shows the histological structure of the skin, which is a large-area organ (surface ca. 1,8 m²) that isolates the organism from the environment. With its large surface, it protects the human body against pathological germs, sunlight, or drying out. The skin consists of different layers: epidermis, dermis (corium) and subcutis. The skin contains dermal appendages like sweat glands, oil glands (here clogged and inflamed), and scent glands, blood vessels, nerve endings, thermoreceptors, and touch receptors, that serve as protection, but also communication with the environment.
