Making Hair Loss History: Native Polyphenols to Kick-start Hair Regrowth

Research has shown the deregulation of two major hair follicle cell types are involved in androgenic alopecia: human fibroblast dermal papilla cells (HFDPc) and outer root sheath cells (ORSc). This article explores the effects of an active blend containing dihydroquercetin glucoside and epigallocatechin glucoside to stimulate ORSc and HFDPc, in turn reversing hair loss.

[NYSCC Suppliers’ Day 2017] Chemyunion Talks Efficacy at the Show

Companies at the show had at least one launch, trend or new technology to talk to attendees about, but Chemyunion came prepared with multiple new ingredients, ranges and test results to chat about.

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.

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.

In relation, these authors propose a new in vitro test to compare the wet skin factor of sun care products. Here, 20 products were tested and compared according to several conditions in order to define the best parameters for the method.

In vivo Delivery Confirmation: Measuring the Deposition of Salicylic Acid from Anti-acne Face Wash

Measuring the delivery of active ingredients is an important part of the product development process, and particularly desirable are non-invasive, in vivo methods. This work describes the use of fluorescence excitation emission matrices in vivo to measure the deposition of salicylic acid from anti-acne face wash products.
