What does exfoliation peel do to the skin's outer layer?

1. Sloughs the outer layers of the stratum corneum

2. Hydrates the skin

3. Brightens the complexion

4. Repairs skin damage

The correct answer is: Sloughs the outer layers of the stratum corneum

Exfoliation peels are specifically designed to remove dead skin cells from the outermost layer of the skin, known as the stratum corneum. This process, often referred to as "sloughing," helps to enhance the texture and appearance of the skin by allowing fresher, healthier skin to emerge. By effectively removing the buildup of dead cells, exfoliation can promote cell turnover and encourage the skin to rejuvenate itself, leading to a smoother and more radiant complexion. Other options, while they may be benefits of a broader skincare routine or different treatments, do not specifically describe the primary action of exfoliation peels. Hydration is more about moisture retention than cell removal, brightening the complexion can be a secondary effect but is not the main action, and repairing skin damage typically involves more intensive treatments than what is described by an exfoliation peel. Therefore, the primary and most accurate function of an exfoliation peel is to slough off these outer layers, making the skin appear healthier and more vibrant.
