Nanotechnology, Inflammation and the Skin Barrier: Innovative Approaches for Skin Health and Cosmesis

Dermatologic physiology and aesthetics are profoundly connected. Inflammatory stimuli abound in the environment, and have the potential to impact both the physiology and aesthetics of the integument. Inflammation results in a compromised epidermal barrier, impaired moisture retention, erythema, scale and pigment alteration. The advent of nanotechnology has introduced a variety of new approaches to preserving skin cosmesis in the face of inflammation. In this article, we review the architecture and physiology of the epidermal barrier, describe the pathological and aesthetic effects of inflammation, and report recent advances in the development of nanomaterials to offset the aesthetic impact of inflammation.
