On the Effect of Glycolic Acid on Skin Thickness

In modern times and skin maintenance, the use of glycolic acid has become more and more widespread. However, the impact of glycolic acid on skin thickness is what everyone is concerned about.

Glycolic acid belongs to α-hydroxy acids and the like. Its effect on the skin is quite complicated. According to research, glycolic acid can promote the renewal of stratum corneum cells. The stratum corneum is the outermost structure of the skin. If it is renewed and orderly, the skin condition may be improved. When glycolic acid is applied to the skin, it can loosen the connections between keratinocytes, making the old keratinocytes easy to fall off, and then promote the differentiation and maturation of the underlying cells to accelerate, and form a new stratum corneum. In this process, the skin metabolism accelerates, or indirectly affects

Studies have shown that moderate use of products containing glycolic acid can thicken the epidermis. This is due to active proliferation of underlying cells, more cells participate in epidermal construction, resulting in increased epidermal thickness. However, this thickening is not disorderly growth, but an orderly and healthy state. Thickening of the epidermis can enhance the skin barrier function. Like city wall reinforcement, external stimuli such as ultraviolet rays and pollutants are more difficult to invade the inside of the skin, thus protecting the skin.

However, everything is appropriate. If glycolic acid is used improperly, or the concentration is too high, and the frequency of use is too dense, there are also disadvantages. Excessive concentration of glycolic acid may cause skin irritation and inflammatory reactions. Under inflammation, the skin may be red, swollen, tingling, etc. Long-term inflammation not only does not benefit the thickening of the skin, but can damage the skin structure, hinder normal metabolism, and even cause the skin to become thinner and more sensitive.

Therefore, if you want to use glycolic acid to thicken the skin, you should be cautious. According to the individual skin type, choose the product with the appropriate concentration, and follow the correct use method, in order to achieve the effect of thickening the skin and nourishing the skin, and avoid its harm.

To sum up, the effect of glycolic acid on skin thickness has both opportunities and challenges. If used reasonably, it can become a good skin care method; if misused, it may damage the skin.
