In clinical practice, I often hear patients say they have “oily dry skin”, which is indeed an incredible statement when you consider it carefully. Why do you say you have oily skin? If you have oily skin, why do you say you have dry skin? In fact, it is very common for many patients to have oily skin, but often confused because of dryness. The reason for this situation is actually very simple. Some patients think they have oily skin, so they always scrub their skin very hard, which makes the oil come off excessively, thus leading to dry skin. At the same time, excessive grinding of the skin surface destroys the barrier role of the skin, resulting in a decrease in the skin’s ability to retain water, which further aggravates the dryness of the skin. After the skin is dry, it will lead to excessive secretion of sebum, and there will be a situation of more oil. The solution is also very simple, is not to wash away the oil, using the “no friction” method of washing the face. In this way, the sebum will not be excessively shed, the barrier function of the epidermis will be restored, and the excessive secretion of sebum will naturally stop after the dry state is repaired.
