How is skin exfoliation beneficial?

It promotes hair growth
It removes dead skin cells and promotes cell renewal
It increases moisture retention
It lightens skin tone

The correct answer is: It removes dead skin cells and promotes cell renewal

Skin exfoliation is particularly beneficial because it effectively removes dead skin cells from the surface of the skin. This process reveals fresh, healthier skin underneath and stimulates the growth of new skin cells, promoting overall cell renewal. By encouraging this turnover, exfoliation helps improve skin texture, clarity, and tone, making it look more vibrant and youthful. A key outcome of this process is unblocking pores, which can help prevent issues such as acne and dullness, further enhancing skin health. The other choices, while they may touch on aspects related to skin care, do not encapsulate the primary functions and benefits of exfoliation as effectively. For example, promoting hair growth is unrelated to the mechanisms of exfoliation, and while moisture retention can be an indirect result of improved skin health, it is not a direct benefit of the exfoliation process itself. Lightening skin tone may be achieved through various treatments but is not a fundamental function of exfoliation.
