SEBO: what is it? what is needed?
The sebum it is a natural secretion of the skin elaborated by specific glands called sebaceous, located under the skin of the whole body, except on the palms of the hands and feet. It is an oily fatty substance that contributes to the hydration of the skin thanks to the maintenance of the hydrolipidic film, the natural barrier of the skin, the first bulwark of protection from external agents.

fatty acids
squalene

The sebaceous glands have a round shape and are located just below the surface of the skin, in the dermal layer, not present evenly in the body. The sebum produced by the sebaceous gland flows into the hair follicle and from there to the surface of the skin.
The sebum is the promoter of numerous activities: it is a good one waterproofing for the skin, it makes it soft and pliable, it has anti-fungal properties and finally determines the specific odor of the individual.
Many factors can determine a increase or decrease in sebum production. Generally, the peak of production occurs during puberty.

As we age, the body reduces sebum production and it is precisely for this reason that older people are more prone to have a dry skin .
