Name a common skin treatment available in a barber shop.

Exfoliating scrubs are a common skin treatment found in many barber shops. These scrubs are designed to remove dead skin cells and impurities from the skin's surface, promoting a smoother and brighter complexion. They often contain granular substances or chemical exfoliants that help to slough off old skin, enhance skin texture, and improve overall skin health. This treatment can be beneficial before a shave, as it allows for a closer and smoother shave by providing a clearer surface for the razor.

While microdermabrasion, facial serums, and peel-off masks are effective skincare treatments, they are less commonly performed in barber shops compared to exfoliating scrubs. Microdermabrasion is typically offered at skincare clinics and spas due to its more in-depth, equipment-based nature. Facial serums are usually products used at home for skincare routines rather than treatments offered at a barber shop. Peel-off masks, while popular, are more often associated with at-home skincare or specialized beauty salons rather than barbering services. Therefore, exfoliating scrubs are the most standard and accessible treatment in this context.
