Cosmetic Lipids
and the Skin Barrier
edited by Thomas Förster

This state-of-the-art reference provides essential quantitative information on the interaction of topically applied lipids with skin barrier lipids—focusing on new biophysical and analytical methods that can assess lipid status and the improvement of skin condition.

Exploring how different lipid varieties function in cosmetic formulations and on the skin, Cosmetic Lipids and the Skin Barrier:

• reviews synthetic skin barrier lipid analogues in creams
• presents evidence for results obtained by lipidic refatters in personal cleansing products
• reveals benefits of molecular dynamics and computerized lamellar layer research
• highlights in vivo and in vitro studies of the stratum corneum
• discusses the use of infrared and Raman spectroscopy as powerful tools in skin surface inspection
• surveys the physicochemical properties of various lipids
• analyzes consumer perceptions of leave-on and rinse-off products

Containing contributions from internationally recognized specialists and over 1000 references, drawings, photographs, and tables, Cosmetic Lipids and the Skin Barrier is an up-to-date resource for cosmetic scientists and technologists; dermatologists; skin biologists; physical, surface, colloid, analytical, and formulation chemists and biochemists; regulatory personnel; and upper-level undergraduate and graduate students in these disciplines.
