For external use, the clay may be added to the bath, or prepared in wet packs or poultices for application to specific parts of the body. Often, warm packs are prepared; the heat opens up the pores of the skin, and helps the interaction of the clay with the body. [notes 4]
There is a clear proportionality between pore throat radii and hydraulic conductivity. Also, there tends to be a proportionality between pore throat radii and pore volume. If the proportionality between pore throat radii and porosity exists then a proportionality between porosity and hydraulic conductivity may exist.
“Clay masks are great for acne-prone, oily skin as the clay draws out the impurities from deep in the pores,” Green tells SPY. “[They] will speed up the process of healing active breakouts.”
Fuller's earth has been used extensively for many years in motion pictures for a variety of applications, spanning from make-up, wardrobe, and set dressing, to special effects. In the area of special effects, it is used in pyrotechnics explosions and dust clouds, because it spreads farther and higher than most natural soils, resulting in a ...
The perceived effect of a facial mask treatment can be revitalizing, rejuvenating or refreshing. Although widely believed to provide tighter pores, increased skin clarity, and a reduction in facial skin wrinkles, masks have not been shown to be any more effective at accomplishing these things than a standard moisturizing lotion.

Micro CT of porous medium: Pores of the porous medium shown as purple color and impermeable porous matrix shown as green-yellow color. Pore structure is a common term employed to characterize the porosity, pore size, pore size distribution, and pore morphology (such as pore shape, surface roughness, and tortuosity of pore channels) of a porous medium.
[36] [37] [38] It consists of pure clay, without any mixture of ingredients. [36] Bentonite clay is available worldwide as a digestive aid; kaolin is also widely used as a digestive aid and as the base for some medicines. Attapulgite, another type of clay, is an active ingredient in many anti-diarrheal medicines. [26]
Representative bulk densities of soils. The percentage pore space was calculated using 2.7 g/cm 3 for particle density except for the peat soil, which is estimated.
