What is the main purpose of applying face powder?

The primary purpose of applying face powder is to set the foundation, which helps to lock in makeup and prolong its wear throughout the day. When foundation is applied, it can remain tacky or moist, and face powder works by absorbing excess oils and providing a matte finish. This not only helps to reduce shine but also creates a smooth surface that can enhance the overall appearance of the makeup.

When foundation is set with powder, it can prevent creasing and ensure a more polished, blended look. In addition to setting the foundation, powder can also provide a lightweight layer that helps to control oil and shine for those with oily skin types, making it an essential step in many makeup routines.

While face powder can have other effects, such as adding a subtle tint if colored powders are used, its primary function is to set the foundation and create a smooth, matte finish.
