Dr SubramanyamAcne is an inflammatory disorder of the skin resulting from an overactive sebaceous gland. It is marked by the eruption of pimples or pustules especially on the face.
Process of acne informationAcne formation begins with excessive secretion of sebum that blocks the hair follicle, the passage that leads from the sebaceous gland to the surface of the skin. Normally sebum helps in removing the dead cells from the lining of the hair follicle and in carrying them to the outer skin surface. However, if the amount of sebum secreted from sebaceous gland increases, it blocks the hair follicle thus making it difficult for dead cells to reach the skin surface. As a result, the dead cells get trapped.
These dead cells combine with sebum and bacteria to form a plug in the follicle. When infection remains under the skin surface, it develops into white head. When the infection partly reaches the surface and changes color it develops into black head.
