Oily skin

Oily skin is characterized by a shiny, oily to the touch, thick and dull aspect. It is sensitive and delicate as dry skin, although it has different characteristics. Pores are dilated especially in the area of nose and cheeks, highlighting the so-called lemon peel appearance. Sebum changes the appearance of the skin depending on its qualitative and quantitative changes, influenced by hormones. The excreted sebum by the sebaceous glands can flow from the dilated follicular ducts and generate an oily appearance or be waxy and remain stagnant in the follicle forming blackheads. Observed with a magnifying glass oily skin shows an expansion of the hosts pilo-sebaceous often associated with a thickening of the stratum corneum, hyperkeratosis, the skin is dull and lifeless, full of blackheads.

Oily skin is affected by unbalanced diets in which fats are the main culprits, together with chocolate, nuts, stress, anxiety states and air pollution. Increase the imperfections of oily skin also trivial factors like "fringe" that in these cases facilitates the formation of blackheads and pimples on the forehead.

Advise:

cleansing, the first essential cosmetic gesture, must be particularly careful and performed morning and evening. The detergent used aims to gently remove excess sebum and small impurities. A too energic degreasing leaves the skin without adequate protection and favors the "rebound effect" that is an extra burst of sebum.

The detergent should be easy to rinse, and does not leave residue of sebum and dirt on the skin, it should be free of alcohol and parabens.

After the cleaning is essential to use specific treatments sebum-balancing.

Sebum is known to be normal wool for the presence of cholesterol that is able to emulsify fats with water. The sebum of oily skin is mainly hydrophobic because it is poor of cholesterol. The balance of water and fat is broken causing the increase in lubricity and thickening of the lipid film surface. When unsaturated fatty acids decreased, simultaneously increase the hydrocarbons and the skin loses its ability to self-sterilization becoming more prone to irritations and infections.

The predisposition to an overproduction of sebum from glands is inherited from parents. This factor does not appear at birth, but occurs during puberty, when hormones urge the sebaceous glands. This is a typical endocrine seborrhea of the adolescence and is due to the impaired response of the gland following a normal stress hormones. The lifeless skin, characteristic of the adolescent, is due to hypersecretion of sebaceous wax type that invades the follicle often associated with hyperkeratosis of the stratum corneum. On this type of skin there are blackheads and acne and it requires professional advice of a dermatologist.
