What is the main function of a clay mask in skin care?

The main function of a clay mask in skin care is to desquamate and refine the skin. Clay masks are particularly known for their ability to draw out impurities, excess oil, and toxins from the skin, making them effective for individuals with oily or acne-prone skin. The clays, often composed of ingredients like kaolin or bentonite, work by exfoliating the surface layer of the skin, thereby promoting the shedding of dead skin cells. This process contributes to refining the skin's texture, leaving it smoother and more even.

In addition to their exfoliating properties, clay masks can also help to absorb excess sebum, reduce the appearance of pores, and improve overall skin clarity. These benefits focus on enhancing the skin's tone and texture, which aligns with the idea of refinement through desquamation, making this the most appropriate functionality of a clay mask in the context of skin care.
