On the cause of skin itching caused by glycolic acid
In recent times, people mostly use glycolic acid for skin care, but some use it for itchy skin. I have tried to investigate this principle to understand the cause of itching.

Glycolic acid is sexually active, with small molecules, and can quickly penetrate the surface of the skin. When it is first used, the skin or not used, the stratum corneum is disturbed by it. The stratum corneum is also the barrier of the skin. If this barrier is slightly damaged, the nerve endings of the skin are easily exposed. Nerve endings sense stimulation from foreign objects, and then transmit itching to the brain. This is one of the reasons.

In addition, glycolic acid can promote the metabolism of the skin and cause rapid cell turnover. However, the rhythm of skin metabolism has its own rhythm. If it changes suddenly, the immune mechanism of the skin may be misjudged to be different, triggering an immune response. Immune cells tend to it and release chemical messengers, including those that make blood vessels dilate and nerves sensitive, which are also the cause of itching.

Furthermore, individual skin is different. Or those with sensitive skin have weak tolerance to glycolic acid. That is, the usual dosage is like a powerful medicine for the other, the skin is unbearable, and itching occurs.

To relieve this itching, it is advisable to try it on a small scale before use to observe the skin's reaction. If the itching has already occurred, stop it immediately, cleanse the skin with water, and slow down its irritation. Or use a soothing agent to help the skin recover.

The method of treating the skin should carefully examine the differences of individuals, know the nature of glycolic acid, and use it carefully to ensure the health of the skin and avoid itching and pain.
