Development of acne
Development of acne, cross section trough the epidermis and dermis with hair and sebaceous glands. The illustration shows the histological structure of the skin. The skin is a surface organ that establishes the border between the organism and the environment. Its surface of ca. 1,8 m² protects the human body from pathological germs, sunlight or dehydration. The skin consists of various layers: The epidermis, dermis (corium) and finally the hypoderm (subcutis). There are cutaneous appendages like sweat glands, sebaceous glands (here clogged and inflamed), and scent glands, vessels, nerve endings, thermoreceptors and sensory receptors, whose function is protection of the skin, but also its interaction with the environment.
