How is Mild Acne Formed?
The study of how acne is formed is a fascinating one.The arrival of puberty causes a surge of androgenic hormones in the body. They have specific action on the sebaceous glands, which start secreting thick, sticky oily sebum into the hair follicle ducts. The hormones also act on the lining cells of the follicular wall, which become thickened and keratinous. This cellular debris and the sticky sebum accumulate in the hair follicle duct and form a plug to close the pore. This plug is known as a microcomedone. When the keratinous plug pushes out under a thin layer of the skin, it is known as closed comedone or whitehead. When the opening is open, it widens under the pressure from the plug to form a blackhead or open comedone. The black color of the blackheads is not due to dirt accumulation, but due the action of oxygen in the atmosphere on the fatty acids of the sebum.
