Which statement about exfoliation is true?

The statement that exfoliation helps in removing dead skin cells is true and highlights a fundamental aspect of skincare. Exfoliation is the process of sloughing away the top layer of dead skin cells from the skin’s surface, which can improve skin texture and promote cellular turnover. This action not only clears away dead cells but also helps to unclog pores, reduce the appearance of blemishes, and can enhance the overall brightness and radiance of the skin.

Exfoliating can lead to smoother skin by revealing fresher, healthier skin underneath. This is particularly beneficial in addressing various skin concerns such as dullness, uneven texture, and aging signs, as it encourages the body's natural regeneration processes.

In contrast, other statements do not reflect accurate practices related to exfoliation. Regular daily exfoliation may not be suitable for all skin types, especially sensitive or reactive skin, where it could lead to irritation. Furthermore, exfoliation positively affects skin texture rather than having no effect on it, and while it can be beneficial for oily skin, it is not deemed unnecessary, as all skin types can benefit from removing dead skin cells to maintain healthy and balanced skin.
