Oily Skin: shine-free skin starts here

What is oily skin?

Oily skin is a skin type that is characterized by an overproduction of sebum. This secretion of sebum takes place in the areas where the sebaceous glands are found, mainly the face, but also the anterior surface of the thorax and the central part of the back.

An increase in sebum production occurs with an increase in androgen (male hormones) production, beginning in the teen years. It can also occur, for the first time, in menopausal women. Testosterone is secreted into the body and enters the sebaceous glands. The enzyme 5a reductase converts testosterone into dihydrotestosterone, which stimulates sebum production. In some cases, sebum production is balanced, as the skin requires oil to ensure proper barrier function and remain supple and pliable. It is the overproduction of sebum that causes the skin to become excessively oily.


What is a good skincare routine for oily skin?

With oily skin, we need to be careful not to “strip” the skin of oil, as this will only make the skin increase its sebum production to rebalance itself. Avoid alcohol that dries out the skin and disrupts the barrier function.

A cleansing gel, as opposed to a cleansing milk, is often preferred for oilier skin types. It is imperative to cleanse the skin morning and evening.

Exfoliation is also important, as excess oil acts as a “glue” that holds dead cells on the surface of the skin. This impairs the penetration of active ingredients into the skin and suffocates the skin, as it is unable to take in the oxygen it requires. Often, oily skin appears dull with a grayish undertone resulting from impaired respiration that is caused by this buildup of dead cells.


Creams and concentrates, with active ingredients that assist in balancing the sebaceous secretions, that diminish bacteria and that leave a matte finish, should be used morning and evening. Most products for oily skin are water-based, however, they may contain some specific oils that are non-comedogenic to keep skin secretions balanced.
