On the effect of glycolic acid on rosacea skin
The disease of rosacea, patients often suffer from facial skin changes, erythema, papules, pustules, and physical and mental fatigue. Glycolic acid has a unique effect on the treatment of rosacea skin, so it is discussed in detail.

Glycolic acid belongs to α-hydroxy acid. Its molecules are tiny and can penetrate into the stratum corneum of the skin. In rosacea skin, the main function is to improve the metabolism of the stratum corneum. In rosacea patients, the metabolism of the stratum corneum may be disordered, resulting in keratin accumulation, rough skin and prone to inflammation. Glycolic acid can promote the separation of keratinocytes, thin the too thick stratum corneum, and make the skin smooth again. Looking at it, the skin surface scales are reduced, and the touch is also more delicate.

Furthermore, glycolic acid can start the process of cell renewal. It stimulates the division and proliferation of basal cells, and new cells migrate up to replace senescent cells. This is of great significance to rosacea skin. New cells can carry better functions and repair damaged tissues. Such as erythema, through cell renewal, blood vessels dilate slowly, and the color of erythema fades.

And glycolic acid has antibacterial properties. The inflammation of rosacea may be related to the growth of Demodex follicularis and bacteria. Glycolic acid can create an environment that is not suitable for the survival of bacteria and insects, reduce their number, and then control the spread of inflammation. The number of pustules and papules decreases.

When using glycolic acid on rosacea skin, it should be used with caution. It is irritating to a certain extent, and when used initially, the skin may feel tingling and redness. Therefore, a skin test must be done before use, and the concentration and frequency of use should be gradually increased since the low concentration. When used, it is also necessary to strictly follow the doctor's advice to ensure skin safety.

In short, glycolic acid has great potential for the treatment of rosacea skin. Rational use can relieve the suffering of patients and restore the beauty of the skin. Doctors and patients should take it seriously, and use scientific methods to obtain its good effects.
