What is one of the main goals of routine skin exfoliation?

One of the main goals of routine skin exfoliation is to brighten the skin's tone. Exfoliation helps remove dead skin cells from the surface of the skin, which can accumulate and lead to a dull, uneven complexion. By sloughing off these dead cells, exfoliation reveals fresher, newer skin beneath, which often has a more vibrant and uniform tone. Regular exfoliation can also enhance the effectiveness of other skincare products, allowing them to penetrate better and result in improved skin luminosity and texture.

The other choices do not align with the primary purpose of exfoliation. Stimulating hair growth is not a result of exfoliation; rather, it pertains more to specific treatments aimed at the hair follicles. Encouraging faster healing of wounds is more relevant to specific healing ingredients or treatments, rather than the act of exfoliation itself. Finally, while some exfoliants may provide a temporary tightening effect, the primary goal of exfoliation is more focused on surface cell renewal and skin tone improvement rather than skin tightening.
