Whether retinoic acid can be mixed with glycolic acid is a question that has attracted much attention in skin care. Retinoic acid, known for its ability to regulate the differentiation and proliferation of epidermal cells, has been effective in improving abnormal skin keratosis, anti-aging and wrinkle; glycolic acid, as a member of the fruit acid family, can loosen the connection between keratinocytes, promote the exfoliation of the stratum corneum, rejuvenate the skin, and improve its smoothness and color.

However, when the two are mixed, caution is required. Retinoic acid itself has a certain irritation to the skin, or causes the skin to redness, desquamation, and burning. Glycolic acid is also irritating. If the two are superimposed, this irritation may be significantly enhanced, which is beyond the tolerance limit of the skin.

Under normal circumstances, it is not recommended to mix the two directly. If you want to use retinoic acid and glycolic acid at the same time to achieve better skin care effect, it should be done in time. You can use glycolic acid products first during the day, and then do a good job of sun protection; at night, when the skin condition is stable, then use retinoic acid. In this way, it can not only give full play to the advantages of both, but also avoid damage to the skin caused by excessive stimulation. And at the beginning of use, you should try it from a low concentration and a small area, observe the skin reaction, and then make adjustments. In short, skin care should take care of the skin and choose and match products reasonably according to your own skin type.
