No, snail mucin does not contain glycolic acid. Snail mucin, also known as snail secretion filtrate, is a popular ingredient in skincare products due to its potential benefits for the skin. It is rich in nutrients, such as hyaluronic acid, peptides, and glycoproteins, which can help hydrate and nourish the skin. However, snail mucin does not naturally contain glycolic acid, which is a type of alpha hydroxy acid (AHA) commonly derived from sugarcane or other natural sources. Glycolic acid is known for its exfoliating properties and is often used in skincare products to promote cell turnover and improve the appearance of skin texture and tone.
