Center for Skin Sciences Established, Reports New Findings in Skin Tanning

Twenty five years after a fire claimed many lives, the Center for Skin Sciences at the University of Bradford (Bradford, UK), specializing in wound healing, was officially established to honor those who died. The occasion was marked by a symposium. In addition, the group recently announced new findings in relation to sunburn-prone skin and the potential for tanning.

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.

Is Asian Skin Really Different from Black or Caucasian Skin?

It often is claimed, particularly in East Asia, that Asian skin is more sensitive than Black or Caucasian. To explore this claim, the author investigates the current literature in this review and concludes there are two aspects being overlooked: the skin’s capability to cope with perturbations and the route of penetration.

Gene Variable Identified to Predict European Hair Curliness

Researchers at the Queensland Institute of Medical Research have identified a link between a gene and the degree of curliness in hair of European descent. This finding could be applied in forensic investigations or be used to manipulate hair with proteins.

Kangaroo DNA Repair Enzyme Could Prevent Skin Cancer

Scientists in Australia and Austria are studying a DNA repair enzyme found in kangaroos that reportedly fights the damage caused by skin cancer.

Study of Twins Correlates Aging with Genetics

While up to 40% of aging-related changes in skin are due to non-genetic factors, a recent study found a high correlation between the photodamage scores among both monozygotic (identical) and dizygotic (fraternal) twins.

The Effects of Showering Too Often, Too Hot and Too Long

This article is about something that anyone with teenage children will recognize: the fact that while you cannot get pre-teens to go into the shower, you cannot get teenagers out of the shower. However, when their showering is too often, too hot and too long, they are steam-stripping their skin.
