What type of product is used to physically remove dead cell buildup?

Mechanical exfoliants are designed to physically scrub away dead skin cells on the surface of the skin. These products often include materials such as grains, beads, or other gritty substances that help to slough off the outer layer of dead cells when massaged onto the skin. The physical action of scrubbing not only aids in removing the buildup of dead cells but can also stimulate circulation, leading to a healthier appearance of the skin.

In contrast, chemical exfoliants use acids or enzymes to dissolve the bonds between dead skin cells, allowing them to be sloughed off without the need for physical scrubbing. Hydrating agents and moisturizers, while essential in a skincare regimen, primarily focus on adding moisture to the skin rather than removing dead cells. Therefore, the correct choice reflects the method of physically removing dead skin, which is central to the function of mechanical exfoliants.
