On Witch Hazel and Glycolic Acid
When physicians explore whether witch hazel contains glycolic acid, this is an important question related to skin care pharmacology.

Witch hazel, the extracts made from its leaves and flowers are quite common in the field of skin care. It has the ability to soothe and converge, and is often used for skin discomfort and oil regulation. Glycolic acid, which belongs to the class of fruit acids, has significant effects on exfoliation and skin rejuvenation, and can make the skin delicate and radiant.

However, in the ancient books, glycolic acid is rarely found in the native ingredients of witch hazel. The effect of witch hazel comes from the tannins, flavonoids and other ingredients it contains, not glycolic acid.

Today's merchants may have products named "witch hazel glycolic acid". The reason is that Gai wants to collect the soothing astringency of witch hazel and the skin rejuvenation of glycolic acid, so as to win the favor of consumers. Those who use these products should carefully review their formulations, clarify their content, and check their skin tolerance. Those with strong glycolic acid and sensitive skin may cause discomfort and redness.

In summary, witch hazel has no glycolic acid. If you see "witch hazel glycolic acid", it is an artificial combination. Users should be cautious to seek the benefits of skin care and avoid the harm of skin damage.
