What is the main purpose of using scrub during a pedicure?

The main purpose of using a scrub during a pedicure is to exfoliate the skin. Exfoliation is the process of removing dead skin cells from the surface of the skin, which helps to improve the skin's texture and appearance. When a scrub is applied, it typically contains granular ingredients that physically slough off the outermost layer of dead skin. This not only reveals fresher, healthier skin underneath but also prepares the feet for further treatments by allowing moisturizers to penetrate better.

In the context of a pedicure, exfoliating the feet can help prevent rough patches and calluses, contributing to an overall smooth and polished look. Additionally, it can stimulate circulation and enhance the effectiveness of subsequent pedicure steps, such as moisturizing.
