Traditional cosmetic mud contains irregular quartz silt upwards of 300 microns. When massaged into wet skin, these jagged mineral fragments shear intercellular lipids, creating invisible micro-fissures that trigger trans-epidermal water loss.
Three Stages of Sifting
Geological Selection
Pharmaceutical Mesh Sifting
Hermetic De-aeration
Raw montmorillonite and kaolinite deposits are mechanically harvested from deep sub-surface strata, avoiding surface loam and biological plant matter.
Milled mineral ore passes through three sequential stainless-steel vibrating meshes, isolating uniform particles precisely at the 75-micron threshold.
Refined powders are vacuum-sealed under inert atmosphere within frosted glass vessels to prevent ambient humidity absorption and clumping.
Particulate Drag Versus Skin
The human stratum corneum is merely twenty microns thick. When cosmetic masks contain uncalibrated mineral grains between 150 and 350 microns, manual application drags jagged stone edges across delicate keratinocyte envelopes, inducing subtle inflammation and post-rinse tightness.
By calibrating particles strictly to 75 microns, ClayBea suspends minerals in liquid as a colloidal slip. The clay binds excess sebum and environmental impurities through electro-chemical cation exchange, leaving epidermal lipid bilayers fully intact after rinsing.
