On the suitability of glycolic acid for dry and wet skin
The nourishment of husband's skin is related to the different states of glycolic acid in dry and wet skin. Its rationale is profound, and it should be studied in detail.

Glycolic acid has unique properties. When used for dry skin, its effect can be described. For dry skin, there is a lack of fluid and less moisturization, and the texture is astringent. Glycolic acid can be applied to the texture of the skin, which can slow down the machine of exfoliation and promote the release of old exfoliation. However, dry skin loses moisture. Although glycolic acid helps to renew the keratin, it may be irritating. If used inadvertently, it may cause dry itching and redness. Therefore, when using glycolic acid for dry skin, it is recommended to test the sensitivity first, and start with a low concentration and a small area. When the skin is suitable, the range and increase can be gradually expanded. When using, it is also necessary to supplement moisturizing products, such as oily plump cream, to protect the skin barrier, resist the danger of glycolic acid stimulation, and achieve the effect of moisturizing and rejuvenating.

As for glycolic acid for wet skin, there are other advantages. The surface of wet skin is hydrated, and glycolic acid is on it, which diffuses quickly and penetrates evenly. It can quickly reach the deep layers of the skin with the power of moisture, and act efficiently on cell metabolism. It can more smoothly promote keratinocyte renewal, making the skin bright and smooth. And the moisture can slightly slow the irritation of glycolic acid and reduce the feeling of discomfort. However, when using it for wet skin, there are also points to pay attention. Although the wet state reduces irritation, excessive use or prolonged residence time may still damage the skin barrier. Therefore, when using glycolic acid for wet skin, it needs to be controlled in quantity and time, and according to the tolerance of the skin, so as to make good use of its effect and avoid its drawbacks.

In short, glycolic acid has advantages and disadvantages when used for dry and wet skin. For dry skin, it is important to protect and gradually adapt; for wet skin, it is necessary to protect the barrier when controlling the amount. Only by understanding and using it well can we obtain the beauty of skin maintenance, make the skin rejuvenated, and keep it moist and healthy.
