Skin Barrier Function

  • Chapter
  • First Online:

Abstract

In this chapter, we will describe first an overview of current concepts of epidermal barrier function emphasizing very recent work on the influence of pigmentation on barrier function. Then, we will assess how these mechanisms go awry in the disease, atopic dermatitis, as the prototype for a barrier-driven, inflammatory dermatosis.
