Oregon Esthetics Law Practice Exam

Instruments are devices designed to work with tools to perform a procedure. They extend the capability of tools by adding precision, control, and safety, making it the best fit for “items that complement the use of tools.” In esthetics practice, you might use various specialized devices alongside basic tools to achieve the intended result, which is exactly what instruments describe.

Materials refer to the substances used during a service, equipment means the larger machines or setups, and accessories are add-ons that accompany the primary tools but aren’t themselves the devices that enable the procedure. So instruments best capture the idea of items that complement tool use.
