What is one benefit of using exfoliants in skincare?

Using exfoliants in skincare primarily improves skin texture by removing dead skin cells, which is why this option is the correct choice. Exfoliation helps to slough off the outermost layer of dead skin, encouraging cell turnover and revealing fresher, healthier skin beneath. This process can lead to a smoother, more radiant complexion and can also enhance the absorption of other skincare products, making them more effective.

The other options, while relevant to skincare, do not accurately describe a primary benefit of exfoliants. Adding moisture to the skin is more commonly associated with moisturizers rather than exfoliants, as they work to hydrate rather than exfoliate. Sun protection is typically provided by sunscreens, which have active ingredients designed to shield the skin from UV damage, not by exfoliants. Lastly, makeup removal is a function of cleansers or makeup removing products rather than being an effect of exfoliation.
