Which type of exfoliation would NOT be classified as mechanical?

1. Chemical peel

2. Microdermabrasion

3. Scrubs

4. Skin brushing

The correct answer is: Chemical peel

A chemical peel utilizes specific acids or enzymes to dissolve dead skin cells and promote skin cell turnover, rather than relying on physical friction or movement. This process alters the skin's surface through a chemical reaction, effectively exfoliating the skin without the need for any mechanical action. In contrast, methods such as microdermabrasion, scrubs, and skin brushing involve some form of physical abrasion or friction against the skin. Microdermabrasion uses tiny crystals or a diamond-tipped wand to physically buff away the outer layer of skin. Scrubs typically contain granular particles or exfoliating agents that physically scrub away dead skin cells when applied. Similarly, skin brushing involves using a brush to mechanically remove dead skin and stimulate circulation. Thus, chemical peels are classified distinctly from mechanical exfoliation methods due to their reliance on chemical agents rather than physical means.
