On whether glycolic acid causes tingling
The world has asked the doctor: "Glycolic acid can be used for skin care, but when it is applied, it often feels tingling, why?"

The doctor should say: "Glycolic acid, which is a fruit acid, has the ability to rejuvenate the skin, can exfoliate and promote skin regeneration. However, the skin is different, and its tolerance is different. For those who tolerate strong, or only feel a slight heat, there is no risk of tingling; for those who tolerate weak, glycolic acid enters the skin, stimulates nerve endings, and causes pain."

Ask again: "Is there a way to avoid this tingling?"

The doctor replied: "When starting to use it, it is advisable to try it with a low concentration, and gradually increase the frequency and concentration to make the skin suitable. And moisturize the skin before use, and moisturize and care after use, which can relieve discomfort. If the tingling is severe, stop using it immediately and consult a doctor for help."

Therefore, although the effect of glycolic acid is good, those who use it need to understand the nature of the skin and use it carefully to enjoy its benefits and avoid its harm.
