What is the role of glycolic acid in skincare?

To moisturize and hydrate the skin

To exfoliate and promote cell turnover

Glycolic acid is a type of alpha hydroxy acid (AHA) that plays a significant role in skincare primarily through its exfoliating properties. It works by loosening the bonds between dead skin cells on the surface of the skin, which promotes a process known as cell turnover. This means that dead skin cells are sloughed off more easily, allowing for the emergence of fresher, healthier skin underneath. As a result, glycolic acid helps to improve skin texture, reduce the appearance of fine lines and wrinkles, and can also enhance the overall brightness of the complexion.

Additionally, by promoting cell turnover, glycolic acid can increase the skin's ability to absorb other skincare products more effectively, making it a valuable ingredient in many treatments aimed at achieving smoother and more radiant skin.
