Analysis of Glycolic Acid Tingling
Or when someone uses glycolic acid, the reason for this should be carefully investigated. Glycolic acid, a fruit acid, has unique chemical properties. Its molecules are small, penetrating, and can quickly reach the deep layers of the skin.

The skin has its own barrier, like a city wall protecting the city. Glycolic acid first touches, like an "uninvited guest", causing the skin to be uncomfortable for a while. The stratum corneum bears the brunt, and the lipids between keratinocytes encounter glycolic acid, causing some structural changes, making the skin barrier temporarily weak. At this time, external stimuli are more likely to reach nerve endings, and the feeling of tingling occurs.

Furthermore, glycolic acid may stimulate epidermal nerve fibers. Nerve fibers in the skin are sensitive to environmental changes. Glycolic acid causes pH to drop, environmental changes, nerve fibers are stimulated, electrical signals are transmitted to the brain, and people feel tingling.

In addition, individual skin differences are also key. Sensitive skin is like a delicate stamen, with a weak barrier and sensitive nerves. With glycolic acid, the tingling may be more severe; while healthy and tolerant skin has strong adaptability to glycolic acid, and the tingling may be light or no.

In short, glycolic acid tingling is not for no reason, but is related to skin barrier, nerve stimulation, and individual skin type. Those who use it should predict their own skin type, use it cautiously, so that glycolic acid can be used to promote its longevity and avoid its shortness when skin care.
