Which of the following is an example of a poleolytic (protein dissolving) treatment?

A gommage is an effective formulation often used in skincare that provides a poleolytic (protein dissolving) action. This treatment typically involves applying a gel or lotion that contains enzymes or acids designed to help break down and dissolve dead skin cells, sebum, and other impurities on the skin's surface. The key characteristic of a gommage is its ability to chemically exfoliate the skin through the dissolution of proteins, making it distinct from other exfoliating treatments which might primarily rely on physical abrasion or scrubbing.

In comparing gommage to other treatments listed, an exfoliating scrub focuses more on physical exfoliation through the use of granules or particles that mechanically slough off dead skin rather than breaking down proteins. Microdermabrasion utilizes a device to gently sand the skin, also emphasizing mechanical action rather than a biochemical response. Facial steam mainly serves to enhance hydration and open pores but does not provide the same protein-dissolving effect as a gommage. Thus, gommage stands out as the method specifically aimed at poleolytic action.
