What do mobile estheticians typically do?

Mobile estheticians are professionals who provide skincare and beauty services outside of traditional salon settings. They typically own portable equipment, which allows them to perform treatments in clients' homes or at their workplaces. This flexibility is a key characteristic of mobile esthetics, enabling practitioners to cater to clients who prefer the convenience and privacy of receiving services in their own environments.

The other choices do not accurately capture the nature of mobile estheticians. For instance, working exclusively in salons would limit their ability to offer their services in various locations as mobile estheticians do. Providing services only in spas contradicts the concept of mobility, as spas are fixed locations. Selling beauty products online, while it can complement a mobile esthetician's services, does not encompass the primary function of providing skincare treatments. Therefore, owning portable equipment and making house or office calls distinctly defines the role of mobile estheticians.
