Topical Resveratrol, Topical/Ingested Grape Seed and Natural Supplements Found to Inhibit Skin Cancer
Researchers at the University of Texas Health Science Center, San Antonio, report that the combination of topical resveratrol, topical or dietary grape seed extract, and calcium D-glucarate and ellagic acid supplements suppress skin cancer and inflammation. These findings could be used to develop supplements or creams to protect skin.

Variations in Pigmentation and Ultrastructural Skin Differences Among Ethnic Groups
By: Rupa Pugashetti, MD, Santa Clara Valley Medica…
As formulators create products for varying ethnic backgrounds and with diverse skin types, an understanding of differences in pigmentation and skin structure and function becomes more important. This column reviews recent studies on the structural, genetic and ultraviolet (UV)-responsive differences in skin pigmentation to allow the formulator to create successful products for varying ethnicities and to accurately measure pigmentation.

Enhancing Sunscreen Efficacy for Realistic Application
By: Elsa Jungman, University of Paris XI, and Howa…
The ability of a sunscreen to protect the skin from erythema is expressed on product labels as the sunburn protection factor (SPF)—i.e., the ratio of the minimum erythema dose (MED) with sunscreen to the MED without protection. Yet in reality, consumers do not apply the same mass/cm2 as is utilized in SPF testing, so maximal protection is not achieved.

Researchers Identify Physiological Sensor Important for Skin Barrier Function
Researchers at the National Institute for Physiological Sciences (NIPS) have reported that the transient receptor potential vanilloid 4 (TRPV4) ion channel in keratinocytes is important to maintain skin barrier function and prevent skin dehydation. According to these researchers, chemicals that modulate TRPV4 activity, could affect barrier repair of damaged skin.

Research Reveals Multiple Conformations of Collagen
Collin Stultz, Massachusetts Institute of Technology (MIT) associate professor, cardiologist and biomedical engineer, recently examined how collagen breaks down in his work published online in the journal Biochemistry. His research suggests that collagen has multiple conformations, both rigid and flexible, that depend upon temperature.

Is Cosmetic Science Really "Bad"? Part V: Who do you think you are fooling?
By: Johann W. Wiechers, PhD, JW Solutions
In previous installments of this series, the author applied Michael Shermer's Baloney Detection Kit, which includes ten questions to ask to validate a science, to cosmetic science. Having previously applied the first eight questions, the author addresses the final two in this installment.
