Analysis of glycolic acid and endogenous hair
Glycolic acid has attracted more and more attention in the field of skin care. The trouble of endogenous hair often makes the skin uncomfortable and affects the appearance. Today, we will investigate whether glycolic acid can stop endogenous hair.

Glycolic acid is an alpha-hydroxy acid with unique chemical properties. Its molecules are small and can easily penetrate into the surface of the skin, exerting multiple effects. In terms of keratin metabolism, glycolic acid can loosen the connections between keratinocytes and promote the shedding of old keratin. One of the causes of endogenous hair is that during the growth process, the hair is blocked by the thick stratum corneum and cannot penetrate the surface of the skin normally, thus growing inward. By improving the keratin metabolism, glycolic acid can make the stratum corneum around the hair thinner and more permeable, allowing the hair to pass out smoothly and reducing the chance of endogenous hair formation.

From the perspective of the hair follicle microenvironment, glycolic acid can slightly stimulate the dermis and promote the formation of collagen and elastic fibers. A healthy hair follicle microenvironment is essential for normal hair growth. If the surrounding tissue of the hair follicle is elastic and the nutrient supply is sufficient, the hair is more likely to grow in the normal direction. The optimization of the hair follicle microenvironment by glycolic acid indirectly helps to prevent endogenous hair.

Many practices can also be used as evidence. After long-term regular use of skin care products containing glycolic acid, some people find that the endogenous hair condition that was originally frequent has improved. The surface of the skin becomes smoother, and the discomfort symptoms caused by endogenous hair such as redness, swelling, and pain are also reduced.

However, although glycolic acid is beneficial, it should be used with caution. Because it is irritating to a certain extent, if the concentration is too high or used improperly, it is easy to cause skin allergies, redness, swelling, and tingling. Beginners should start with low-concentration products and gradually build skin tolerance. The frequency of use should also be gradual and not excessive.

In summary, glycolic acid does have potential in preventing and improving endogenous hair. However, rational and scientific use is the key to avoid possible skin damage when harvesting skin beauty effects.
