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.

Small, Smaller and Nano Materials: An Invisible Benefit

Although nanomaterials have been used in cosmetics for some time, consumers believe they may constitute a health risk due to their possible penetration into the skin. The present article evaluates the benefits as well as the skin penetration of nanoparticles used in cosmetics.

Unexpected Lessons in Dermatotoxicology: De minimis Magnesium++

Traditional dermatotoxicologic investigations focus on dermatitis as well as potential systemic effects1 but rarely have they focused on trace ions. The following lesson opens new avenues of thought and investigation for intimate care product developers, since the trace ions described may dramatically impact the end product.

Researcher Develops Lauric Acid Anti-acne 'Bombs'

In recent research from the University of California, San Diego, Jacobs School of Engineering, a smart delivery system coupled with lauric acid has been shown to deliver nano-scale liposome "bombs" to kill acne bacteria.

Researchers Reverse the Age of Cells with Induced Stem Cells

A team of North American researchers have demonstrated a reversal of the developmental aging of normal human cells with induced pluripotent stem cells.
