The skin on the lips is delicate, and whether glycolic acid can be used on the lips is of practical significance.

Glycolic acid, one of the fruit acids, has a certain exfoliation effect and is often seen in skin rejuvenation products. However, the skin on the lips is different from other parts of the face. The stratum corneum is thinner and has no sebaceous glands, and the self-protection ability is weak.

If you rashly use glycolic acid on the lips, it may cause many problems. In light cases, the lips are redness, dryness, and desquamation. This is due to glycolic acid irritating the stratum corneum, causing water loss; in severe cases, it may cause allergies, such as itching, tingling, and even swelling, which affects the normal state of the lips

Therefore, if you want to use glycolic acid to care for your lips, you need to be cautious. If the lip problem is serious, you should consult a professional dermatologist first and choose the appropriate care method according to their suggestions. Even if the lip is only slightly uncomfortable, it should be tested on a small area of skin first to see if there are any adverse reactions. After confirming that it is safe, you should use it cautiously on the lips. And the frequency of use should not be high, and the concentration should be low. Moisturize in time after use to protect the health of the lip skin.
