The connection between glycolic acid and acne
The disease of acne has puzzled everyone for a long time. Recently, glycolic acid has emerged in the field of skin care, and its association with acne has attracted much attention.

Glycolic acid belongs to alpha-hydroxy acids. Its molecules are small and can easily penetrate into the surface of the skin. The stratum corneum of the skin is closely arranged by keratinocytes, just like a city wall. However, too thick "city walls" can easily cause blockage of the hair follicle mouth, resulting in acne. Glycolic acid has the unique ability to loosen the connection between keratinocytes, causing the too thick stratum corneum to gradually fall off, which is the so-called exfoliation. After the blockage of the hair follicle mouth is removed, the sebum excretion is smooth, and the foundation of acne generation is weakened.

Furthermore, glycolic acid can stimulate the metabolism of the skin. The metabolism of skin cells is like an endless stream of water, new cells are generated, and old cells are replaced. When the metabolism is slow, old cells are easy to accumulate, hindering the normal physiological function of the skin. Glycolic acid can stimulate cell vitality, accelerate the metabolic process, and prompt new healthy cells to quickly replace old cells. In this way, the skin condition can be improved, which is beneficial to the prevention and treatment of acne.

In addition, inflammation is a key link in the pathogenesis of acne. Glycolic acid has certain anti-inflammatory properties, which can reduce the inflammatory reactions such as redness, swelling and pain caused by acne. It can inhibit the release of inflammatory factors, regulate the skin's immune response, and act like a wise general to calm the "war" in the skin and restore tranquility to the skin.

However, when using glycolic acid, you should also be cautious. Because it is irritating to a certain extent, if used improperly, it will cause skin discomfort, such as redness, swelling, tingling, etc. For beginners, it is recommended to try it on a small area of skin first to observe whether there are any adverse reactions. And the frequency of use should be gradual and not rushed.

In summary, glycolic acid is closely related to acne. Reasonable use of glycolic acid products may provide an effective way to improve acne problems. Only by using it effectively can we obtain its benefits and avoid its harm.
