The causes of spots appearance (or, scientifically, acne) can be various factors. But the mechanism of development, typically involves four main elements.
Lets consider the four main causes of acne:
Elevated levels of male sex hormones (hyperandrogenic)
Hyperactivity sebaceous
Cornification of skin tissue (follicular hyperkeratosis)
Acne and Bacteria
Hyperactivity sebaceous
Not many people know that virtually the entire surface of the skin is covered with microscopic sebaceous glands. The only exceptions are palms and soles.
However, these glands cover the body not uniformly: the largest and most frequently are located on face particularly on nose and cheeks, as well as on the upper chest, above the shoulder-blades and between them.
The sebaceous glands lie at a level of about 0.5 mm below the surface of the skin. In places of the highest concentrations of sebaceous glands (scalp, forehead, chin, back), their number reaches 800 or more per 1 cm2.
In the course of life, the depth of the skin and the magnitude of the sebaceous glands are changing. The younger the child, the greater its sebaceous glands, the more they work, and closer they located.
However, over the years, the activity of these glands gradually slow down, some of them dying. The chemical composition and texture of sebum is changing. This continues until the beginning of puberty: the action of hormones (in particular, male sex hormones – androgens) sebaceous glands increase their secretary activity increases, reaching the “maximum life” for 18-25 years.
The sebaceous glands are different from short hair and long hair. The largest glands are located just where there are typical elements of acne – in the places of greatest congestion. They consist of many parts and that is why they are called sebaceous follicles.
The main objective of the sebaceous glands, as it follows from their names – producing sebum. It serves as a lubricant for the hair during their growth, softens the upper layer of the epidermis, protects the skin from the water, microorganisms, giving it elasticity. Within 24 hours the sebaceous glands secrete up to 20 g secretion, consisting of fatty acids, fats, cholesterol, glycerol, etc. Mingling with the sweat, the fat forms a thin pellicle of water-fat emulsion (“acid mantle of the skin”), which plays an important role in maintaining the normal state of the skin.
But it is only in cases where the functioning of the sebaceous glands is normal. Continue reading
