What technique involves the use of a solution to remove dead skin cells?

1. Exfoliation

2. Hydration

3. Moisturizing

4. Protection

The correct answer is: Exfoliation

Exfoliation is the technique that involves the use of a solution or physical method to remove dead skin cells from the surface of the skin. This process helps to improve skin texture, reduce the appearance of fine lines, and promote cell renewal. By eliminating the layer of dead cells, exfoliation allows for better penetration of skincare products and reveals healthier, smoother skin underneath. Hydration refers to the process of adding moisture to the skin but does not specifically involve removing dead skin cells. Moisturizing also focuses on hydrating the skin and providing a protective barrier without the intent of removing dead cells. Protection involves safeguarding the skin from environmental factors like UV rays, pollution, and harmful substances, which does not entail the removal of dead skin cells either. Hence, the focus of exfoliation on dead skin cell removal makes it the correct answer.
