Kallikrein is a serine protease enzyme. Overactivity of kallikrein-related peptidases (KLK5, KLK7) in the skin is implicated in rosacea, psoriasis, and impaired barrier function. Formulators must ensure controlled enzymatic activity to avoid disruption of the skin barrier or excessive cathelicidin processing. Not recommended for compromised or sensitized skin.. Kallikrein enzymes play a critical role in skin desquamation by hydrolyzing corneodesmosomes and processing profilaggrin. In cosmetic...
