On the Correct Use of Glycolic Acid
If you want to make good use of glycolic acid, you must first understand its properties. Glycolic acid has unique chemical characteristics. It has both merits and demerits in the way of skin care, so the method of use should not be careless.

First of all, review the quality of the skin. The skin may be dry or oily, sensitive or healthy, with different states. For dry skin, when using glycolic acid, it should be slow and thin. Because of its lack of moisturization, the peeling power of glycolic acid, if used too properly, may cause dry skin and loss of moisture. For oily skin, it can be slightly heavier, but it should not be excessive to prevent skin stress and anti-oil disease. Sensitive skin, especially need to be cautious. It is recommended to try it on a small part of the skin first, observe its reaction, and use it gradually if there is no discomfort.

Furthermore, know the order of use. After cleansing, the skin is initially cleansed. At this time, use glycolic acid, and its effect is easy to show. However, you need to wait for the skin to be slightly dry before applying glycolic acid products. When applying, the action should be light and evenly spread on the face to avoid delicate places such as the eyes and lips. And after use, you need to protect it with moisturizing products in time to replenish its moisture and solidify its skin barrier.

Again, control the frequency of use. Although glycolic acid has the power of rejuvenating the skin, it is overused and will hurt the skin. For beginners, it is recommended to use it once to twice a week. When the skin adapts, it can be gradually increased to three to four times a week. Do not use it frequently because of quick effect, resulting in skin damage, redness, swelling and tingling.

At the end of the year, heavy sun protection is required. After using glycolic acid, the skin's resistance to ultraviolet rays is slightly reduced. Therefore, when using it during the day, you must apply sunscreen products to avoid direct sunlight to prevent the skin from tanning and sunburn, and the results fall short.

In short, use glycolic acid, according to the quality of the skin, follow the correct order, control the frequency of use, and heavy sun protection, in order to obtain its benefits, avoid its harm, and achieve a good state of skin care.
