In makeup, what is the purpose of using a brow gel?

Using a brow gel serves the primary purpose of holding eyebrows in place, ensuring they maintain a well-groomed and polished appearance throughout the day. Brow gels are often formulated with a lightweight, sometimes clear, texture that helps to set the hairs without weighing them down or making them feel sticky. This results in a defined, tidy look that enhances the overall makeup application and adds to the professionalism of the makeup artist's work.

While brow gels can also sometimes offer a hint of color or tint, their main function is to control the brow hairs and shape them, making option C the most accurate choice regarding their purpose in makeup. Other options, such as enhancing or darkening the color of the eyebrows, may be features of specific brow products but are not the core purpose of brow gel itself.
