The Air Up There: Skin VOCs
In 2001, Japanese researchers reported that after the age of 40, some individuals develop a malodor known as “aging odor,” attributed to the presence of unsaturated C9, 2-nonenal. George Preti, PhD, a member of Monell Chemical Senses Center and an adjunct professor of dermatology at the University of Pennsylvania School of Medicine, was interested by this report and began to conduct research of his own.

Why the FDA's 'Sunscreens in the Bloodstream' Study is Flawed
A recent study published in the
Journal of the American Medical Association
tested the potential systemic absorption of certain sunscreens. Results identified their presence in subjects' bloodstreams; however, as industry expert David Steinberg explains, the study is misleading and fails to consider crucial variables.

The Dirty Truth About Pollution-induced Skin Aging: The AhR Pathway Tells All
Studies have shown that exposure to airborne, traffic-related particulate matter (PM) is associated with increased signs of extrinsic skin aging.1-3 Using model particles as surrogates, these researchers developed an in vitro model to evaluate premature aging induced via the aryl hydrocarbon receptor (AhR) pathway. They found a new AhR antagonist could inhibit the up-regulation of genes indicative for premature aging.

Skin Toxicology—The Future May Be Orange
Here, industry expert Johann Wiechers, PhD, discusses the frequent use of percentages by toxicologists to calculate skin penetration. To relate this discussion to modern day events, Wiechers describes the skin penetration of orange paint, used by fans of the Dutch national football team.

Predicting the Percutaneous Penetration of Cosmetic Ingredients
While previous algorithms for predicting the skin absorption of permeants was based on in vitro data, the present article proposes a quantitative structure-activity relationship (QSAR) model based on in vivo human data. Here, a set of human in vivo data is described that provides entry into predicting the penetration of cosmetic ingredients.
