What is the primary purpose of mechanical exfoliation?

1. Hydration

2. Detoxification

3. Layer of skin removal

4. Sunscreen application

The correct answer is: Layer of skin removal

The primary purpose of mechanical exfoliation is the removal of the outermost layers of the skin, specifically dead skin cells. This process helps to promote cell turnover, resulting in a smoother and more radiant complexion. By physically sloughing off these dead cells, mechanical exfoliation enhances the skin's texture and allows for better absorption of skincare products that follow. While hydration, detoxification, and sunscreen application play important roles in overall skincare, they do not directly pertain to the primary effect of mechanical exfoliation. Hydration focuses on adding moisture to the skin, detoxification refers to clearing the skin of impurities, and sunscreen application is essential for protecting the skin from UV damage. However, these functions do not relate to the actual action of removing layers of skin, which is the core aim of mechanical exfoliation.
