Acne is one of the most common skin diseases. Its appearance is influenced by many factors. The general mechanism of the formation of acne lesions does not hide any secrets. It all starts with the increased production of sebaceous gland secretions and the simultaneous hyperkeratosis of the epidermis. In such a situation, the sebum produced in large amounts cannot freely reach the skin surface and clogs the sebaceous glands. The secretions become trapped in the epidermis, forming first micro-blackheads and then closed blackheads. In adolescence, it is closely related to hormonal changes. Acne is no longer just a problem for young people, but has also become a common skin condition in adults.
