What type of ingredient is often found in exfoliating scrubs?

Exfoliating scrubs typically contain ingredients that help to remove dead skin cells and promote smoother, healthier skin. The use of microbeads or natural scrubs such as sugar or salt is particularly effective because these materials physically help slough off the upper layers of the skin during application.

Microbeads provide a synthetic option but have been largely phased out due to environmental concerns, prompting a shift towards natural alternatives. Sugar and salt are preferred in many formulations because they dissolve in water, offering a gentler, yet effective exfoliation that can be adjusted based on the pressure applied during use.

Natural oils, while beneficial for moisturizing and hydrating the skin, do not have the same exfoliating properties. Similarly, hyaluronic acid and glycerin are known for their hydrating characteristics but do not serve the purpose of exfoliating the skin. Peptides or proteins are ingredients that target skin repair and regeneration but are not typically associated with exfoliation. Therefore, the focus on microbeads, sugar, or salt clearly positions this choice as the most relevant to the function of exfoliation in scrubs.
