Target intelligence / Profile preview

Skin Surface

Molecular classification: Epithelial Tissue, Anatomical Structure

Overview

The skin surface is the outermost boundary of the human body, primarily composed of the epidermis. It acts as a dynamic barrier between internal tissues and the external environment. It is a complex structure made up of multiple cell types, layers, and associated appendages, serving critical protective and sensory roles.

Other names: EpidermisCutaneous SurfaceIntegument

Mechanism of action

Varies depending on the drug and its target within the skin. For example, topical corticosteroids reduce inflammation by suppressing the immune response in the skin. Sunscreens block UV radiation.
