Glycolic acid is a type of alpha hydroxy acid (AHA) that is found in sugarcane and other natural sources. It is commonly used in skincare products due to its ability to exfoliate the skin by removing the top layers of dead skin cells. This helps to reveal newer, brighter layers of skin underneath and can improve skin texture, tone, and radiance. Glycolic acid also stimulates new cell generation, which can help to reduce the appearance of fine lines and wrinkles. Additionally, it can boost collagen production, which can make the skin appear smoother and firmer. Glycolic acid is used to treat a variety of skin conditions, including acne, aging skin, dark skin patches on the face, and acne scars. It is also used to improve the appearance of stretch marks, hyperpigmentation, enlarged pores, psoriasis, keratosis pilaris, and hyperkeratosis. Glycolic acid is generally considered safe for use in skincare products, but it can cause skin irritation and sensitivity in some people, especially at higher concentrations. It is important to follow the instructions on the product label and to use sunscreen when using glycolic acid products, as they can increase the skins sensitivity to the sun.
