Rapid Colorimetric Analysis of para-Phenylenediamine in Henna-based, Non-permanent Tattoo Color Mixtures
In some henna mixtures, para-phenylenediamine (PPD) has illegally been added and it is responsible for complications such as allergic contact dermatitis. While high-performance liquid chromatography has previously been used to detect PPD, a colorimetric method that is faster and portable, described here, has been developed. For product developers, this method can be used to evaluate henna plant extracts.

Bio + Chemo Guidance Uncover New Benefits in Known Naturals:
Murraya Koenigii
Extract Case Study
Murraya koenigii
extracts derived via various techniques were compared. One developed through chem- and bio-guidance paired with a natural deep eutectic technology uncovered lesser-known efficacies, leading to a natural active to boost elastin synthesis.

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.

Narcissus Tazetta
and
Schizandra Chinensis
to Regulate ‘Youth Gene Clusters’—An In vitro Analysis
A blend of
Narcissus tazetta
bulb and
Schizandra chinensis
fruit extracts was developed for anti-aging benefits and tested for efficacy on a human skin equivalent. Results indicate it regulates the functions of youth gene clusters by increasing the activities found in younger skin and reducing the activities found in aging skin specific to structure, hydration, cellular proliferation and pigmentation.

In the Land of the Blind: Applying a Single-blind Study to Finished Products
Following positive feedback from a previous column on the placebo effect, Wiechers readdresses clinical study design in relation to cosmetic claim substantiation—this time discussing when to perform double-blind studies and when to perform single-blind studies.

Snail Slime, MMP-2 Trigger and More: Advances in Delivery and Efficacy at IFSCC19
Using the same approach to develop or test a product will not result in a step-change innovation. For this reason, new solutions to deliver, develop and test product efficacy were presented during the 2019 IFSCC Conference.

Fluorescence Laser Scanning Confocal Microscopy to Assess the Penetration of Low Molecular Protein Hydrolyzates Into Hair
The present study uses confocal laser scanning fluorescence microscopy to assess the penetration of protein hydrolyzates into hair. While higher amounts of protein were found in the cuticle, still significant quantities were observed in the cortical parts of hair, and this penetration was enhanced by longer incubation times.
