What is a common ingredient found in exfoliating scrubs?

Sugar or salt is a common ingredient found in exfoliating scrubs due to their gritty texture, which effectively helps to remove dead skin cells from the surface of the skin. These natural exfoliants not only provide physical exfoliation but also have the added benefit of being easily accessible and cost-effective. When massaged onto the skin, the granules of sugar or salt help to slough away the outer layer of dead skin, promoting smoother and more radiant skin underneath.

In addition to their exfoliating properties, sugar and salt also have moisturizing properties; sugar is a natural humectant, which means it draws moisture to the skin. Salt, especially when used in conjunction with oils, can help to soften the skin while cleaning out pores.

Other options, while beneficial in their own right, do not typically serve the primary purpose of exfoliation in scrubs. Cocoa powder is often more associated with nourishing the skin rather than exfoliating, shea butter is known for its moisturizing properties rather than as an exfoliant, and liquid soap might be used in scrubs primarily for cleansing rather than physical exfoliation.
