People with oily skin are often disturbed by excessive oil secretion, resulting in oily skin, enlarged pores, and prone to acne diseases. Glycolic acid has gradually attracted attention in the field of skin care, and its effect on oily skin has been explored in real terms.

Glycolic acid is one of the α-hydroxy acids with unique chemical properties. Its molecules are small and can easily penetrate the stratum corneum of the skin. For oily skin, glycolic acid regulates oil secretion first. It can act on the sebaceous glands to moderately inhibit excessive oil production, balance the amount of oil on the surface of the skin, and then reduce oil shine and make the skin look refreshing.

Furthermore, glycolic acid can promote keratin metabolism. The stratum corneum of oily skin is often metabolized disordered due to the accumulation of oil. Glycolic acid can loosen the connection between keratinocytes, accelerate the shedding of old waste keratin, and return the skin's metabolism to normal. In this way, pores can be unobstructed, reducing the risk of blockage and reducing the chance of acne formation. And the new stratum corneum is more delicate and smooth, and the texture of the skin has also been improved.

And glycolic acid has a certain moisturizing effect. Although oily skin has a lot of oil secretion, its moisturizing ability may not be good. Glycolic acid can improve the skin's hydration ability, help the skin retain moisture, and achieve a balance of water and oil, so that the skin is neither too greasy nor dry.

And sun protection should be paid attention to when using, because glycolic acid makes the skin more vulnerable to UV damage.

In summary, glycolic acid does have many benefits in oily skin care. It can regulate oil, improve keratin metabolism and moisturize, but rational use is the key, so as to restore oily skin to a healthy luster.
