What characteristic of clay/mud masks helps prevent clogged pores?

Clay or mud masks are known for their ability to absorb excess oil from the skin, making them particularly beneficial for individuals with oily or acne-prone skin. When applied, these masks draw out impurities and sebum from the pores, which helps to keep them clear and prevents clogging. By reducing excess oil, clay masks can help minimize the appearance of pores and reduce the likelihood of breakouts.

The other options, while beneficial aspects of certain masks, do not primarily contribute to preventing clogged pores. Delivering beneficial ingredients may enhance skin health, hydrating and moisturizing properties can improve skin texture, and increased circulation can have various positive effects on skin rejuvenation. However, it is the oil-absorbing characteristic that directly addresses the issue of clogged pores, making it the most relevant answer in this context.
