Skin Cell Proliferation Controlled Via PPARβ/δ Protein

In the most recent issue of the Journal of Cell Biology, researchers reveal that skin fibroblasts use a protein called PPARβ/δ to control the proliferation of epithelial cells.

Scientists Examine Bryophytes to Understand Innate UV Protection

A study from Minnesota State University examined the effects of UV on bryophytes to understand the development of innate defenses against UV with the goal of understanding its impact on crops, ecological systems and humans.

Transfollicular Delivery: The (W)hole Story

Various routes of entry into the skin exist, both through the SC as well as eccrine and transfollicular shunt routes. While these shunt routes may comprise only 0.1% of the skin surface, some chemicals that cannot penetrate the SC have penetrated via these routes. As a consequence, transfollicular research is being revived.

Hormesis and Cosmetic Dermatology

This review examines hormetic effects of various agents on skin biology. Recognition of this emerging biological phenomenon in dermatology could lead to markedly improved integrative assessments of animal/human skin responses to toxic substances and pharmacological agents, as well as endogenous agonists.

Eye Area Problems: Puffiness, Bags, Dark Cicles and Crowsfeet

To develop active treatment products that address eye area problems, i.e., puffiness, bags, dark circles and crowsfeet, the cosmetic chemist must better understand the biology of the eye area, the effects of aging and chronic sun exposure and how to select ingredient that will provide stuitable benefit.

Fat-synthesizing Enzyme Found to Affect the Health of Skin and Hair

Showcasing that the health of the skin and body are truly intertwined, a recent study of a fat-synthesizing enzyme provides information on how the body processes and reacts to retinoic acid.

Beeswax Could Be Threatened by Bee Shortage

The decline in honeybees could be due to infections, lack of food, pesticides and breeding, but the consensus is that honeybees are in trouble.

Berkeley Lab Finds Skin Benefit in Cancer-inducing Protein

The lab suggests that the protein linked to the spread of several major human cancers may also benefit skin.

Researchers Find Hydrocyanine Sensors Allow ROS Imaging In vivo

Research conducted in Georgia reports that a family of sensors based on a hydrocyanine scaffold allows imaging of reactive oxygen species (ROS) in vivo.

Researchers Switch Stem Cell Production "On"

Scientists at the Imperial College in London have found a way to turn "on" the production of specific adult stem cells in bone marrow, a technique that could boost the body's ability to repair itself.

Top Scientific Innovations of 2008

Microfluidics, a white laser confocal instrument, a PET/MRI combined imaging system, and a continuing-focus microscopy instrument were ranked among the top ten life science inventions of 2008.

Sensitive Skin Syndrome: Relationships Among Factors

Sensitive skin is a subjective, lay term that many consumers claim affects their comfort when using products that contact their skin. Approximately one-half of individuals surveyed in two research studies considered themselves to have sensitive skin. Researchers know this condition exists, yet it is notoriously difficult to quantify in a meaningful and uniform way.
