Science
Mechanism of Action
Functions through a dual-action mechanism where calcium carbonate crystals provide physical UV blockade and sebum absorption, while bioactive shell proteins trigger collagen type I synthesis via TGF-beta/SMAD2 pathway activation. The ingredient simultaneously upregulates hyaluronic acid production by stimulating Hyaluronan Synthases (HAS1, HAS2, HAS3) and enhances skin barrier function through increased Aquaporin-3 and filaggrin expression in keratinocytes.
