On the Mixture of Retinoic Acid and Glycolic Acid
The principle of compatibility is as good as fine. Retinoic acid and glycolic acid are both commonly used for skin care, but whether it is appropriate to mix them needs to be explored in detail.

Retinoic acid can promote the renewal of skin cells, make the metabolism of the stratum corneum orderly, and often improve acne, wrinkles and other diseases. It is severe in nature, and when used properly, the skin will be rejuvenated; if it loses its degree, it is easy to cause skin redness, swelling and desquamation.

Glycolic acid is a fruit acid, which can loosen the adhesion between keratinocytes, make the skin smooth and delicate, and is also often used to rejuvenate and improve dullness. It is irritating to a certain extent, and it may be uncomfortable for those with thin skin.

As for the combination of the two, caution is required. Captretinoin has increased the sensitivity of the skin, and the addition of glycolic acid stimulates the superposition. In mild cases, the skin is red and itchy; in severe cases, it may cause inflammation and damage the barrier. If the skin has strong tolerance, you can try it before a small piece of skin, observe its reaction, and there is no abnormality before using it gradually. And when using it, it is appropriate to start with a low concentration, step by step, and observe the skin's adaptation.

The way of using medicine is to weigh the pros and cons. The mixing of retinoic acid and glycolic acid, although it may have the possibility of synergy, is accompanied by risks. Doctors should choose carefully according to the characteristics of the patient's skin and the severity of the disease, so as to make the best use of the medicine and avoid its harm, so as to achieve the good state of skin care.
