How does a scrub differ from a peel in skin care?

A scrub is classified as a physical exfoliant due to its use of granular or textured particles that manually slough off dead skin cells from the surface of the skin. This action helps to smooth the skin's texture and enhance circulation by physically scrubbing away impurities and dead skin layers.

In contrast, a peel typically employs chemical exfoliants, such as alpha-hydroxy acids (AHAs) or beta-hydroxy acids (BHAs), to dissolve the bonds holding dead skin cells together. This method allows for a deeper exfoliation without mechanical abrasion, leading to results that can further penetrate the skin and promote cell turnover over time.

Understanding the distinction between physical and chemical exfoliation is crucial in skin care, as it influences the choice of treatment based on individual skin types and concerns. For instance, those with sensitive skin might benefit more from chemical peels that can offer non-abrasive exfoliation, while individuals with tougher skin types might prefer the more immediate results from physical scrubs.
