What is the purpose of exfoliating in a skincare routine?

Exfoliating plays a crucial role in a skincare routine primarily by removing dead skin cells from the surface of the skin. This process is vital for improving overall skin texture, making it smoother and more radiant. When dead skin cells accumulate, they can lead to a variety of skin issues such as dullness, rough patches, and even clogging of pores, which can contribute to breakouts. By regularly exfoliating, individuals can promote cell turnover and encourage the growth of fresh, healthy skin underneath, leading to a brighter and more youthful appearance.

It’s important to note that while exfoliation can help with texture, it is not primarily aimed at hydrating the skin, creating protective barriers, or enhancing makeup application, which are the focuses of the other options. Each of those functions serves specific purposes in skincare, but the primary goal of exfoliation is centered around the removal of dead cells to rejuvenate the skin's surface.
