Proof of the efficacy of dermatological products is a prerequisite for clinical testing and registration. Now, efficacy claims for cosmetics must be equally substantiated. This book provides a concise, practical but comprehensive overview of experimental models used to screen, develop and select dermatological and cosmetic formulations. The authors are recognized specialists in their field and use a standardized approach to the projects facilitating the reading for the stressed scientist, for the R+D managers general view as well as for the beginners in the field.

Cosmeceuticals and Active Cosmetics discusses the science of nearly two dozen cosmeceuticals used today. This third edition provides ample evidence on specific cosmeceutical substances, their classes of use, skin conditions for which they are used, and points of interest arising from other considerations, such as toxicology and manufacturing. The book discusses both cosmetic and therapeutic uses of cosmeceuticals for various conditions including rosacea, dry skin, alopecia, eczema, seborrheic dermatitis, purpura, and vitiligo. Active ingredients in the following products are discussed: caffeine, curcumin, green tea, Rhodiola rosea, milk thistle, and more. Also covered are topical peptides and proteins, amino acids and derivatives, antioxidants, vitamins E and C, niacinamide, botanical extracts, and biomarine actives. Providing ample scientific references, this book is an excellent guide to understanding the science behind the use of cosmeceuticals to treat a variety of dermatological conditions.

Spanning the many advancements that have taken place in the field since the First Edition of this book was published, this Second Edition emphasizes the imaging of the skin in its entirety, rather than focusing solely on surface layers. The Second Edition includes new chapters on technologies such as in vivo confocal laser scanning microscopy, Raman spectroscopy, optical coherence tomography, nuclear magnetic imaging, high-resolution ultrasound, in vivo skin topometry, and multi-photon imaging of the skin.

Bioengineering of the skin, or more precisely the biophysical assessment of skin physiology, is moving rapidly from a descriptive approach to a deeper understanding of biophysical and biochemical processes. This second edition of the popular text Bioengineering of the Skin: Water and Stratum Corneum reflects the progress in the field, focusing on the dramatically improved understanding of skin physiology. Specifically, it reviews the shift in our understanding of the stratum corneum from an inert surrounding sheet to a biologically active compartment. The stratum corneum is the interface between the sometimes harsh environment and the internal turmoil of the human body. Based on a large number of recent publications, this book explains the mechanisms involved in stratum corneum barrier function and hydration. It reflects 10 years of progress not only of the non-invasive biophysical assessment of skin physiology parameter, but also of the perfection of the available devices. It brings all research on epidermal water and transepidermal water loss in health and disease up-to-date with the revision of existing chapters as well as added chapters from new contributors on hydration and itching. This edition also includes new guidelines on the standardization of measurements. Bioengineering of the Skin will enhance communication within the research community and will be useful for scientists in the skin bioengineering field by presenting methods that offer reliable and reproducible approaches for product testing in the pharmaceutical and cosmetic industries, as well as for basic research.

Since skin forms the interface between the human body and the environment, its mechanical properties are important in health and disease. Bioengineering of the Skin: Skin Biomechanics gives a thorough introduction in the biological basis of skin biomechanics. It explains the non-invasive methods that allow measurement of the mechanical properties of the skin focusing on commercially available instruments.

Written by internationally leading experts in the field of non-invasive measurement technology of the skin, this volume describes the anatomy, biochemistry, physiology, and pathology of skin biomechanics. It explains in detail how to measure skin mechanic properties and how to use these measurements in the development of drugs and cosmetics.

Skin bioengineering is an expanding field of investigative and clinical dermatology. This guide describes all commercially available techniques and instruments. It provides a thorough overview of methods for noninvasive investigation of skin function. Commercially available instruments are reviewed and compared, with updated references given for each instrument. This book offers a technical analysis of each instrument, allowing investigators to understand its biophysical principles and to make better purchases of lab instruments. Addresses of manufacturers and worldwide distributors are included, making this an essential reference source.
Chapters are written by international experts. Topics include transepidermal water loss, hydration, the measurement of skin blood flow in Laser-Doppler flowetry, sebum, pH and ions, and transcutaneous pO2 and pO2 measurements. Skin color, roughness, and elasticity are examined in detail. Skin imaging techniques, capillaroscopy, and fluorescence videomicroscopy are described. Instruments for surface microscopy of the skin are also discussed.
Bioengineering of the Skin explains state-of-the-art techniques and is valuable reading for anyone who needs to stay abreast of the latest activities in this ever-changing field.
