What is the purpose of using a clay mask?

The purpose of using a clay mask is primarily to absorb excess oil and impurities from the skin. Clay masks are known for their ability to draw out toxins and impurities due to their absorbent nature. When applied, the mask adheres to the skin and helps to extract excess sebum and dirt from the pores, leading to a clearer complexion. This makes them particularly beneficial for individuals with oily or acne-prone skin, as they can help reduce shine and prevent breakouts by keeping the skin's oil production in check.

In contrast, the primary function of other types of masks may include providing hydration or improving skin elasticity, but those do not align with the characteristic properties of a clay mask. Exfoliation typically involves the physical or chemical removal of dead skin cells, which is not a key function associated with clay masks specifically, as they focus more on drawing out impurities rather than sloughing away the skin's surface.
