What is one function of a facial steamer?

A facial steamer serves several beneficial purposes in esthetics, and one of its primary functions is to soften the skin prior to extractions. When steam is applied to the face, it helps to open up the pores and hydrate the outer layer of the skin. This softening effect makes it easier to remove impurities and blockages from the pores, such as blackheads and whiteheads, during a facial treatment. By loosening dirt and sebum, the steamer facilitates a more effective extraction process, minimizing discomfort for the client and helping achieve clearer skin.

The other options are unrelated to the specific function of a facial steamer. Light therapy involves the use of specific wavelengths of light for various skin conditions and is not performed using steam. Chemical peels utilize acids to exfoliate and improve skin texture; they do not require steaming as part of the application process. While exfoliation does occur in some facial treatments, it is usually performed using scrubs, enzymes, or mechanical devices, rather than through steaming alone.
