What is the primary purpose of exfoliation in skin care?

The primary purpose of exfoliation in skin care is to remove dead skin cells and promote cell turnover. This process is crucial because it helps to reveal fresher and healthier skin beneath the surface. As skin accumulates dead cells over time, it can lead to a dull and uneven complexion. By exfoliating, whether through physical methods (like scrubs) or chemical methods (like acids), the skin can shed these dead cells effectively.

Promoting cell turnover is also beneficial as it encourages the skin to renew itself, which can improve texture, reduce the appearance of fine lines and wrinkles, and help with issues such as acne or hyperpigmentation. This regenerative effect contributes to a brighter, smoother, and more youthful appearance, making exfoliation an essential aspect of an effective skin care routine.
