On glycolic acid and clogged pores
The disease of the skin, clogged pores are a common problem. Recently, glycolic acid has become more and more popular in skin care, but its relationship with clogged pores is controversial and cannot be ignored.

Glycolic acid belongs to the class of fruit acids, which are mild and have unique properties. Its molecules are slender, which can smooth the stratum corneum of the skin and relax the connection between keratinocytes. In normal times, the skin's metabolism is orderly, and keratinocytes shed in a timely manner. However, if the metabolism is sluggish, the old keratin accumulates, and the pores are stuffed. Glycolic acid can help the keratin to renew, make the old keratin peel off, make the skin surface smooth, and the pores seem to be relaxed, which is not easy to be blocked by keratin.

Looking at various practices, many users say that when using products containing glycolic acid, the skin is slightly delicate at first, but after a long time, the pores feel transparent and seem to be clear. However, otherwise, or depending on the individual skin, the tolerance to glycolic acid is different. If the skin is already sensitive, use it rashly, or cause skin stress, which will cause swelling of the tissues around the pores and exacerbate the appearance of blockage. And if used too much, exfoliation is too fast, and the skin barrier is damaged, it will also lead to an imbalance in oil secretion, and the oil will mix with the exfoliated keratin and re-plug the pores.

From this perspective, glycolic acid is not a generalization for pore blockage. Use it reasonably, according to the characteristics of the skin, and it can be used as a good aid to dredge pores; if used improperly, it will be counterproductive. Those who want to take care of the skin should carefully review the condition of the skin and use it carefully to obtain its benefits and avoid its harm.
