What happens to the sebaceous glands?

The sebaceous glands are scattered throughout the body unevenly.So, the skin of the face, as well as the scalp, chest, interscapular area contains a large number of glands.And the skin of the feet and palms does not contain them at all.

The function of these glands is the production of sebum.The greasy secret lubricates the skin and hair, thereby softening them and protecting them from the effects of unfavorable external factors.

Fungus Pityrosporum ovale is an optional skin dweller, concentrating near the ducts of the sebaceous glands.When, under the influence of certain factors, the protective properties of the skin decrease, this leads to an increase in the reproduction of the fungus.Pityrosporum ovale splits sebum to free fatty acids, which it then uses to maintain its vital functions.

But the peculiarity is that free fatty acids have an irritating effect on the skin.So an inflammatory reaction is formed.In addition, in the pathogenesis of the disease, qualitative and quantitative changes in the production of sebum play a role.Structure-sweat glands1
