On the Effect of Glycolic Acid on the Skin Barrier
Skin care practitioners in the world often hear the name of glycolic acid, but there are different opinions on whether it damages the skin barrier. If you want to understand it, you should investigate its essence.

Glycolic acid belongs to the class of fruit acids, with simple molecules and strong penetration. Its effect on the skin is the first to promote keratin renewal. Glycolic acid can loosen the connection between keratinocytes, promote the shedding of old keratin, and make the surface of the skin often new, making it smoother and more delicate.

However, everything has advantages and disadvantages. Glycolic acid has strong permeability. If it is used improperly, or if the concentration is too high and the frequency is too complicated, it is indeed at risk of harming the skin barrier. Skin barriers, such as the walls of city walls, protect the skin from the inside and guard against external objects. Excessive action of glycolic acid may cause lipid imbalance in the barrier structure and damage to the tight connections between cells. If the bricks and soil of the city wall are loose, the gate of the city is solidified, and external stimuli are easy to drive straight in, the skin will be sensitive and dry.

However, do not give up eating because of choking. Use it in moderation, and gradually adjust the way of use according to the skin's tolerance. Glycolic acid can improve the skin without damaging the foundation of the skin barrier. For beginners, it is recommended to choose low-concentration products and use them sparsely. When the skin adapts, consider the frequency of increment and encryption.

Therefore, glycolic acid itself does not necessarily damage the skin barrier. The key lies in whether the user can know its nature and make good use of it. If used properly, it is a good skin care agent; if used incorrectly, it is easy to cause skin problems. Therefore, skin care people should treat it carefully and weigh the pros and cons in order to obtain healthy and moist skin.
