Which of the following is NOT a benefit of moisturizers?

The correct choice highlights the fact that moisturizers primarily aim to hydrate and maintain skin moisture levels rather than provide exfoliation.

Moisturizers play a critical role in hydrating the skin by attracting water and forming a barrier that helps to prevent water loss—these functions are essential for maintaining skin elasticity and overall health. They also can help reduce the appearance of fine lines and wrinkles by plumping the skin, which can lead to a smoother appearance. However, exfoliation is an entirely different skincare process focused on removing dead skin cells to enhance skin texture and promote cell turnover.

While some products contain ingredients that may offer mild exfoliation properties, traditional moisturizers do not inherently provide this benefit, making it the correct answer in the context of the question.
