Does glycolic acid make pigmentation worse: glycolic acid and pigmentation risk
The color of the skin is related to the face. The disease of pigmentation, everyone wants to get rid of it. Glycolic acid is quite common in skin care, but it is related to pigmentation. People may have doubts. Glycolic acid can make pigmentation worse?

Glycolic acid, a fruit acid and the like, is lightweight and can travel through the skin and enter the stratum corneum. Its function is to loosen the adhesion between keratinocytes, promote the shedding of old keratin, and refresh the surface of the skin. It is often used for skin rejuvenation and skin rejuvenation. However, it is also risky when used on the skin.

In the skin, melanocytes are responsible for producing melanin. The amount of melanin determines the depth of skin color. When the skin is irritated, such as sun exposure, inflammation, etc., melanocytes are active, melanin production increases sharply, resulting in pigmentation. Although glycolic acid has the effect of rejuvenating the skin, if it is used improperly, it may irritate the skin. The skin barrier is damaged and inflammation occurs. Under inflammation, melanocytes are like startled birds, melanin production accelerates, and pigmentation may become serious.

And the concentration of glycolic acid is also the key. High concentrations of glycolic acid, although strong in rejuvenating the skin, are also irritating to the skin. Sensitive skin, rashly use high concentrations of glycolic acid, skin intolerance, inflammation, and deterioration of pigmentation. Therefore, when using glycolic acid products, you must choose the appropriate concentration according to your own skin characteristics. When you first use it, you should choose low concentrations, try it on a small scale, and observe the skin reaction. If there is no discomfort, you can gradually expand the scope of use.

In addition, sunscreen is an essential skin care rule. During the use of glycolic acid, you need to pay special attention. Glycolic acid thins the stratum corneum of the skin and weakens the skin's defense against ultraviolet rays. If the sun protection is not good, ultraviolet rays will drive straight in, melanocytes will be stimulated, melanin will increase greatly, and pigmentation will increase. Therefore, after using glycolic acid products during the day, sunscreen must be applied, and physical sunscreen methods such as parasols and sun hats can also be used to protect the skin from ultraviolet rays.

To sum up, glycolic acid itself does not make pigmentation worse, but it cannot be used properly. If the concentration is improper, the skin is intolerant, and the sun protection is not done, there is a risk of pigmentation deterioration. When taking care of the skin, be careful and use glycolic acid reasonably according to the skin condition to achieve the purpose of skin care, and avoid the worry of increased pigmentation.
