Aquaporins: The One-Molecule-at-a-Time Moisturizer

This column describes aquaporins and outlines their 16-year history, with particular interest in an aquaglycero-porin found in human skin. Future columns will highlight the activities of several cosmetic manufacturers and their compositions to “stimulate” that aquaporin as a way to beautify human skin and hair.

Researchers Discover MicroRNA Suppresses p63 Protein

Researchers at Rockefeller University have discovered a tiny RNA molecule that helps create the protective barrier between the inner layer of skin and the surface of skin.

Targeting the Tyrosinase Gene Via the PPARg Complex

Sederma SAS launched a skin brightening ingredient with a new mechanism of action from the heart of the melanocyte.

Columbia Researchers Uncover Hair Density, Texture Gene

A Columbia University research team has discovered a gene involved in determining hair texture that could lead to treatments for unwanted hair, or potentially grow hair.

Exercise May Help Decrease Inflammation in Skin Tissue

University of Illinois researchers have found that exercise can aid in decreasing the inflammation of damaged skin, helping to heal wounds.

Bench & Beyond: Stimulating Sirtuins' Antiaging Appeal

Nicotinamide, the amide of niacin or vitamin B3, is used to treat arthritis. It also has demonstrated anti-inflammatory actions that may be of benefit in patients with inflammatory acne vulgaris. Nicotinamide, therefore, would appear to play a positive role in inhibiting inflammation but a negative role in aging. Are there other ways to stimulate sirtuins?

Sirtuins: A Breakthrough in Antiaging Research

This article reviews the first scientific evidence confirming the presence of sirtuins in the skin, as well as their role in cell survival, senescence and longevity. This vital discovery could lead the way to new and innovative types of antiaging cosmetic ingredients that activate sirtuins.

New Research Shows a Reverse in Skin Aging

Researchers at the Stanford University School of Medicine have reversed the effects of aging on the skin of mice...\\

Researchers Map Genes Causing Dandruff, Other Skin Conditions

Researchers sequence a fungus to shed light on the ways to fight dandruff and other skin conditions.

In Sight: Stimulating Stem Cells for Younger Skin

Stem cell research is a hot topic that cannot be ignored in today’s scientific realm. Its research may lead to the reversal of Parkinson’s and diabetes, to the growth of new organs, to strengthening bones and to healing damaged skin. The research of stem cells in conjunction with burn victims has led to innovation in another field—skin care.

Tech Edge: RNA Interference and Therapeutic Applications

Regular columnist Mindy Goldstein, PhD, welcomes this “Tech Edge” contribution from colleague Narendra Vaish, PhD, of Nastech Pharmaceutical Company.

Dermatological View: Allergic Contact Dermatitis to Linalool

This article reviews the published data on the allergenicity of linalool relating to its relative potency as a skin sensitizer. A semiquantitative evaluation of the different reports cited below has been made in accordance with the system outlined in Maibach et al., which is based on the procedures proposed by Benezra et al.2 and describes the scoring system used for assigning the degree of confidence in data reported.
