What is the function of clay masks in acne treatment?

Clay masks play a significant role in acne treatment primarily due to their ability to absorb excess oil and impurities from the skin. When applied, clay has a unique texture and composition that allows it to draw out excess sebum, which is a common contributor to acne formation. By effectively reducing oiliness on the skin's surface, clay masks help prevent clogged pores that lead to breakouts.

Additionally, clay interacts with skin impurities, such as dirt and toxins, binding to them and facilitating their removal during the rinsing process. This detoxifying effect not only cleanses the skin but also helps maintain a clearer complexion, which is crucial in managing acne-prone skin.

While other options may provide benefits related to skin care, they do not primarily focus on the oil-absorbing and purifying capacity that makes clay masks particularly effective in the treatment of acne. For instance, promoting blood circulation and reducing redness are beneficial for overall skin health, but they are not the main functionality attributed to clay masks in the context of acne treatment.
