Raman Imaging Produces Melanoma 'Snapshot'

Pheomelanin is the red/blond pigment. Its presence has been associated with an elevated risk of melanoma. However, a new technique has been developed to visualize it, which could serve as an early indicator.

Corn-derived Biosurfactant Shows Lower Temp = Higher Hair Adsorption

Want faster hair adsorption? Lower the temperature. As least, that's what one study with a corn-derived biosurfactant, from the Royal Society of Chemistry, showed.

The Perplexing Topic of Hair 'Type': How Do We Classify Hair?

Most hair-related properties and issues can be rationalized by fiber size and shape, and/or the consequences of extreme conditions. However, the varying reactivity of different hair types with chemical treatments suggests potential differences in structure.

Hydration Detection as Simple as a Selfie?

What do you get when you cross the selfie with skin care research and a few brilliant engineers? The mobile turgor test.

IFSCC Has Some Fun with Sun

Sunscreen failure, SPF as a myth, an alternative vitamin D and others were topics of discussion at the sun care session during the IFSCC Congress. Following are some highlights.

Prove It: At-home Use Studies

In-home usage studies put your beauty care brand to the test and yield compelling consumer claims.

'Mirror, Mirror, in the Internet of Things. . .

...use great caution with the advice you bring.' Just what we need. Another critic scrutinizing appearance. And before coffee no less. Yet, this unbiased, digitized evaluation offers interesting potential; and if we don't like it, we can always turn it off.

PCPC's Beth Jonas Defends Cosmetic Science to the U.S. Senate

It's nice to see our government liaison supporting our scientists' efforts by standing up to share with others the notion that cosmetic science is real.

Editor's Note: Positive Vibes

Intuition, vibe, instinct, gut feeling—most of us have experienced it. Science has tried to measure it. What does this have to do with cosmetics? Well, everything.

Quantifying Wellness: Anti-aging Benefits Beyond Wrinkle Reduction

Rather than anti-aging claims, these authors sought to quantify well-being as it relates to the effects of a new active: centcyamine. The authors confirmed a correlation between well-being scores, instrumental observations, self-assessment and, indirectly, in vitro mechanistic data.

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.
