The choice of clays derived from the earth as the base for a setting mask is well-founded due to the unique properties of these clays. Clay masks are known for their ability to absorb excess oils and impurities from the skin, making them highly effective, especially for those with oily or acne-prone skin. This property helps to unclog pores and reduce the appearance of blemishes.

Additionally, clays such as kaolin, bentonite, and fuller's earth also have mineral content, which can provide benefits such as exfoliation, nourishment, and a tightening effect on the skin. When combined with other ingredients, these clays form a paste that can harden as it dries, characteristic of a setting mask, helping to lift impurities from the skin.

In contrast, gelatin serves primarily as a thickening agent in various applications, and while creams may be used in masks, they tend to remain moist rather than setting. Aloe vera, while excellent for soothing and hydration, does not possess the properties required for a traditional setting mask to function effectively. Clays therefore stand out as the most appropriate choice for this purpose.
