All of the following actions are steps of an eyebrow tweezing service, EXCEPT:

In the context of an eyebrow tweezing service, applying barrier cream is not typically a standard step. The primary purpose of eyebrow tweezing is to remove unwanted hair and shape the brows, which involves a process that includes examining the skin, applying powder to absorb any excess moisture and provide a better surface for tweezing, and trimming long hairs if necessary to achieve a clean look.

Barrier creams are generally used in procedures that involve more extensive skin treatments or exfoliation, where protection against irritants is critical. In eyebrow tweezing, the focus is on precision in hair removal rather than on barrier protection for deeper skin treatments. Therefore, the application of barrier cream does not align with the primary goals of an eyebrow tweezing session.
