On the effect of glycolic acid on the fading of acne scars
To explore whether glycolic acid can dilute acne scars is a key topic in skin care. Glycolic acid has attracted much attention in the field of skin care. It is an alpha-hydroxy acid with unique chemical properties and is effective in improving skin quality.

To observe the skin structure, the formation of acne scars originates from the disruption of the tissue repair process after the skin is disturbed by acne, resulting in abnormal proliferation or loss of fibrous tissue. This scar state, either dented or raised, affects the smoothness and beauty of the skin.

The mechanism of action of glycolic acid is to accelerate the metabolism of the stratum corneum. It can loosen the connection between keratinocytes, making it easier for aging keratinocytes to fall off and rapid replacement of new cells. In this way, it can speed up the renewal rate of the skin surface, and gradually improve the appearance and smoothness of mild acne scars, such as superficial scars.

Furthermore, glycolic acid can stimulate collagen synthesis in the dermis. When glycolic acid penetrates into the dermis, it can stimulate the activity of fibroblasts, prompting them to synthesize more collagen and elastic fibers. Collagen provides solid support for the skin, increasing skin elasticity and thickness. For indented scars with collagen loss caused by acne, collagen generated by glycolic acid can fill the depression and gradually calm the scar.

Many clinical practices have also confirmed that glycolic acid is effective in diluting acne scars. However, its effect is not achieved overnight, and it depends on the type of scar, severity, and individual skin differences. Usually, mild acne scars can be significantly improved within a few months after continuous and standardized use of glycolic acid-containing products; while severe scars, although glycolic acid is difficult to completely eliminate, it can also significantly reduce their severity.

To sum up, glycolic acid is an effective means to dilute acne scars. However, when using it, you should be cautious. According to your own skin tolerance, choose the appropriate concentration of the product, and follow the correct use method, in order to not only dilute the effect of scars, but also maintain skin health.
