Consumers Getting Smarter about Health, Nutrition

As "baby boomers" turn 60 this year, it is apparent that consumers in the United States are not getting younger; however, they are getting smarter.

Monell Breakthrough Grows Mature Taste Receptors in the Lab

Researchers have succeeded in growing taste receptor cells outside of the body.

Neuropeptides in Antiaging?

Neuropeptides may be a new source for antiaging applications. According to a recent press release to the personal care industry, some physicians and clinicians say neuropeptides may revitalize skin and hair.

Biobank Project Initiated for Genetics, Disease Studies

Funded by the Wellcome Trust, the Medical Research Council, the Department of Health and the Scottish Executive, the study is designed to examine the interaction of genes, environment and disease in half a million people.

Identification of Differences in Stretch Mark-prone Individuals May Assist In Developing Novel Preventive Therapies

New data, published in the December 2005 issue of the Aesthetic Surgery Journal, suggests new potential for the development of therapies to predict, prevent and treat stretch marks.

Cationic Peptides and Cell Penetration

Controversy surrounds how certain cationic peptides enter the cell.

Nutritional Requirements of Mature Women Examined

Professor Ronni Chernoff examines the nutritional requirements of older women in, “Supplement: Women and Micronutrients: Addressing The Gap Throughout The Life Cycle.”

Stratum Corneum: The Role of Lipids and Ceramides

This paper reviews recent findings about the structure of the stratum corneum and the different models developed to better understand its function and behavior. The roles of intercellular lipids and ceramides as its key constituents are discussed.

Novel Approaches for Molecular Biology and Skin Care Products

The increasing demand for performance-driven personal care products and the need to understand a product’s mechanism of action provides a scientific challenge to the industry formulator, toxicologist and expert evaluator.

Effects of Occlusion (II): Wound Healing

This is the second article in a series discussing effects of occlusion on skin. (The series opened in November 2003 with a focus on percutaneous absorption.) The present article focuses on the effects of occlusive and semipermeable membranes on wound healing and summarizes related data.

Effects of Occlusion (III): Irritant and Allergic Contact Dermatitis

This is the third article in a series discussing effects of occlusion on skin. Previously, we reviewed the effects of occlusion on the percutaneous absorption (C&T November 2003) and on wound healing (C&T April 2004). The present article focuses and summarizes the adverse effects of occlusion. Occlusion enhances skin hydration and increases percutaneous absorption of applied substances with exception. On the other hand, it may also increase the penetration of irritants and/or antigens entering into skin and hence may increase irritant and allergic contact dermatitis. Additionally, occlusion compromises skin barrier function by impairing passive transepidermal water loss at the application site, and hence aggravates the irritant effect of applied compounds.

Gender and Dermatitis

Are females more sensitive to allergens than males? If they are, is it because of something innate in female skin or because of life patterns of exposure to irritants?
