Pattern Overview

Heat-Toxin Trapping the Skin is a severe pattern in rosacea, characterized by inflammatory cytokine storm, papules, pustules, severe erythema, and TLR2/NF-κB pathway overactivation. The core pathogenesis is accumulation of Heat-Toxin in the skin, causing severe inflammation, pustule formation, and facial lesion development.

Western Mechanism Reference

Inflammatory cytokine storm with papule/pustule formation, TLR2/NF-κB pathway overactivation, and cathelicidin abnormality. Heat-Toxin Trapping the Skin corresponds to severe inflammatory rosacea, where TLR2/NF-κB pathway overactivation and cathelicidin abnormalities contribute to severe papule and pustule formation.
