Which ingredient in face masks is known for strong absorbent properties?

Kaolin is a type of clay that is renowned for its strong absorbent properties, making it an ideal ingredient for face masks. This natural mineral is effective in drawing out impurities, excess oil, and toxins from the skin, thus promoting a clearer complexion. It is especially beneficial for oily and acne-prone skin types, as it helps to reduce shine and prevent breakouts.

In contrast, lanolin is a moisturizing agent derived from sheep's wool and does not have absorbent properties; instead, it helps to hydrate and protect the skin. Collagen is a protein that supports skin structure and elasticity but is not known for absorbent qualities. Retinol is a derivative of vitamin A that promotes cell turnover and can enhance skin texture but does not act as an absorbent in face masks. Therefore, kaolin stands out as the key ingredient for its ability to absorb impurities effectively.
