On the use of glycolic acid on the face
In modern times, everyone has attached great importance to the maintenance of facial skin, and glycolic acid has attracted more and more attention in skin care. However, whether glycolic acid can be used on the face needs to be carefully studied.

Glycolic acid belongs to the class of fruit acids and has unique chemical properties. Its molecules are small and can easily penetrate into the surface of the skin. At a suitable concentration, it can promote the renewal of stratum corneum cells. If the stratum corneum is renewed and orderly, the skin can be tender and smooth, and the color may be more uniform. Because glycolic acid can accelerate the shedding of old waste keratin, the metabolism of the skin can be put back on track.

However, the facial skin is delicate and abnormal, and the risk of using glycolic acid coexists. If the concentration is too high, or improper use, it is very easy to cause skin discomfort. Light or short-term tingling, redness, severe can cause skin burns, allergies and other diseases. Therefore, glycolic acid is used on the face for the first heavy skin type screening. For dry skin, the stratum corneum is thin, easy to dry and sensitive. Extra caution is required when using, and it should start from a very low concentration, and the frequency of use should not be high. For oily skin, although the relative tolerance is slightly stronger, it should not be used at high concentration and high frequency.

Furthermore, when using glycolic acid, it is necessary to do a good job of skin adaptability testing. It is recommended to apply a small amount of the product to the skin behind the ear or inside the arm, and observe it for a few hours or even a day. If there is no adverse reaction such as redness, swelling, itching, etc., it can be tried on the face. And during use, sun protection is particularly critical. Glycolic acid makes the skin more sensitive to ultraviolet rays. If sun protection is not done well, it is easy to cause sunburn, tanning, and even accelerate skin aging.

In short, the use of glycolic acid on the face, such as the use of blades on the hands, should be done with caution. Detailed observation of skin type, standardized use, and good protection can take advantage of advantages and avoid disadvantages, and gain the benefits of skin care.
