On the irritation of glycolic acid to the skin
Glycolic acid is quite common in the field of skin care. However, whether it will irritate the skin is a matter of concern to everyone.

Glycolic acid, a fruit acid and the like, has unique chemical properties. Its molecular structure is relatively small, so it can easily penetrate the surface of the skin. When used in moderation and at the right concentration, glycolic acid can promote the metabolism of the stratum corneum, make the skin glow and improve skin texture, such as smoothing the skin and reducing fine lines.

However, if used improperly, glycolic acid can indeed irritate the skin. First, if the concentration is too high, beyond the range that the skin can tolerate, the skin will bear the brunt, will feel tingling, burning, and redness in the appearance. This is due to excessive exfoliation of glycolic acid at excessive concentrations, destroying the skin's barrier function. Second, individual skin tolerance varies. Some people's skin is naturally more sensitive, and even low concentrations of glycolic acid may cause discomfort. For people with sensitive skin, the stratum corneum is relatively weak, and glycolic acid acts like a "double-edged sword". If you are not careful, it will break the stability of the skin, causing itching, tightness, and even rashes.

Furthermore, the frequency of use is also the key. If you use products containing glycolic acid frequently, you will not give the skin enough recovery time, and the skin will be easily overwhelmed, resulting in irritation. The skin itself has its own rhythm of repair and adjustment, and excessive intervention will disrupt this rhythm and cause a series of adverse reactions.

To avoid the irritation of glycolic acid to the skin, users should be cautious. Try it on a small area of skin first and observe it for a few hours to a day. If there is no abnormality, you can expand the scope of use. And you should choose the appropriate concentration and frequency of use according to your own skin condition. In this way, you can enjoy the benefits of glycolic acid skin care while avoiding its irritation to the skin, achieving the dual goals of skin health and beauty.
