Which type of exfoliant uses physical particles to remove dead skin cells?

The correct response centers on the role of physical exfoliants, specifically those that utilize granules like sugar or salt to manually slough away dead skin cells on the skin's surface. These types of exfoliants rely on friction produced when the product is massaged onto the skin, effectively lifting away dead skin and debris while promoting circulation.

Physical exfoliants are particularly popular due to their immediate results and can often be tailored to different skin types based on the size and shape of the particles used in the formulation. Using scrubs containing sugar or salt offers a straightforward and tactile approach to exfoliation, making it easy for users to feel the action taking place on their skin.

In this context, the other options do not align with the definition of a physical exfoliant. Chemical exfoliants utilize active ingredients like alpha-hydroxy acids to dissolve dead skin cells without physical abrasion. Enzyme exfoliants typically employ natural enzymes derived from fruits to gently break down the bonds between dead skin cells for a more subtle exfoliating effect. Hydrating exfoliants, meanwhile, focus on moisturizing the skin rather than removing dead skin cells.
