Skin Surface Proteins

Molecular classification
Structural Proteins, Cytokines, Chemokines, Peptides, Enzymes
01

Overview

Skin surface proteins are a diverse group of molecules present on or near the outermost layer of the skin, primarily within the stratum corneum and epidermis. These proteins play critical roles in maintaining skin barrier function, mediating immune responses, and serving as biomarkers for various dermatological conditions. They include structural proteins like keratin, immune/inflammatory markers such as cytokines and chemokines, and peptides used in skincare. Their levels and activity are often altered in skin diseases.
