On the Causes of Glycolic Acid Causing Oily Skin
On the skin of the world, its oily and dry state is often observed. Recently, it has been said that glycolic acid can make the skin oily, and this theory is very popular. Therefore, it can be used as a lesson for skin care if studied in detail.

Glycolic acid is a fruit acid and the like, with small molecules that can travel freely between skin textures. It often promotes the renewal of the stratum corneum, causing aging keratin to shed and skin to be rejuvenated. However, everything has advantages and disadvantages. Glycolic acid is in this process, or causes changes in the secretion of sebaceous glands.

Sebaceous glands, hidden in the skin, are responsible for the secretion of oil. The irritation of glycolic acid to the skin may disturb the surrounding microenvironment of the sebaceous glands. Or due to differences in signal transduction, the sebaceous glands lose perception and misjudge the amount of oil the skin needs. It is like the transmission of a government order is wrong, and the official in charge is wrong. Therefore, the rate and amount of oil secreted by the sebaceous glands may change, and the oil overflows on the surface of the skin, and the skin becomes greasy.

Furthermore, glycolic acid may affect the skin barrier. The skin barrier is like a city wall, guarding the skin's moisture and foreign body invasion. Excessive action of glycolic acid may cause the bricks (keratinocytes) of the city wall to be disordered, and water loss will increase. For self-protection, the skin promotes the sebaceous glands to increase oil secretion, hoping to replenish water and This is like the frontier is in a hurry, the defenders increase their troops to defend against the enemy, but there are many soldiers and chaos, too much oil, and the greasy skin becomes more and more obvious.

In summary, although glycolic acid is beneficial for the keratin renewal of the skin, it is used improperly, resulting in sebaceous gland secretion disorders and skin barrier damage, resulting in greasy skin. Therefore, when using glycolic acid-containing materials, we should pay attention to the skin's response, step by step, so that the skin can benefit from maintenance and avoid greasy diseases.
