Almost everyone gets acne during puberty. In acne, the sebaceous glands of the skin are inflamed. For one it is a few pimples, for the other it is an extensive skin condition that can even cause psychological problems and determine the pleasure in daily life.
Fortunately, there are now a range of acne treatments available. The condition is annoying, but not dangerous. For most people it is over before the 25th year. Sometimes acne can persist after puberty or only start in adulthood.
Acne is caused by an inflammation of the part of the skin that contains the sebaceous gland. Usually acne starts in puberty when the skin undergoes all kinds of changes due to hormones. The sebaceous glands in the face, back and chest enlarge and produce more sebum or sebum. If too much sebum is made, it accumulates and can clog the sebaceous gland’s output duct. These accumulations of sebum are called blackheads or comedones. There are black and white blackheads.
Blackheads not only contain sebum, they also contain bacteria and fatty acids. At some point, the sebaceous gland ruptures. The sebum, the bacteria and the fatty acids end up in the skin. As a result, the skin inflames and pimples and pimples appear.
