Described here is an image processing system that compensates for changes in illumination and volunteer position, and two algorithms to quantify skin texture and wrinkles. These methods evaluate skin parameters from a single image without contacting skin. Their abilities are demonstrated here in evaluations of the benefits of porous polyamide ultra-fine powders on skin texture and gloss.

This work evaluates the impact of three different substrates on in vitro SPF measurements, and defines experimental conditions to improve their correlation with in vivo values. Evaluations of 32 products, shown here, led the authors to conclude that molded substrates improved repeatability and correlation with in vivo SPF values.

Lab tests on sunscreens show it takes more energy to produce mild erythema on protected skin than unprotected skin. Yet the FDA questions the need for SPFs higher than 50. In response, two outdoor studies were conducted using commercial products to challenge standing premises and determine if there is a measurable difference in an SPF 100 and SPFs of 50 or less.

There are various test methods set by global governing bodies for SPF protection, but this article will discuss the five time-point internationally approved ISO 24444 method.

Endocrine disruptor chemicals (EDCs) are a class of chemicals that has raised alarm for being linked to a wide variety of detrimental effects on human and wildlife populations, e.g., cancers, precocious puberty and obesity. Thus, there is a need to test personal care products and supplements for EDCs, which can be accomplished using the validated bioassay described here.

Here, the author compares two methods to determine the maturity of corneocytes based on their cross-linking that could be used to evaluate the anti-aging effects of molecular agents. The first utilizes microfluorometry, while the second involves F-D curves generated via contact mode AFM. Both methods successfully detected differences in mature or immature corneocytes with 95% confidence.

This article is the first in a series that will address the approaches of measuring the “strength” of hair and quantifying the manner by which this property may be altered. Specifically, it will begin with the generation of stress-strain curves through the use of constant rate extension experiments.

Welcome back to a continuing discussion regarding the new Registration, Evaluation and Authorization of Chemicals (REACH) regulation and its impact on chemical testing. It is the purpose of this series of articles to provide an overview of these existing validated in vitro methods, as well as new methods that are being considered for validation.

It should perhaps go without saying that consumer products are sold using consumer language. Market researchers and consumer scientists spend a great deal of time studying their target audience and learning this vocabulary, which subsequently allows the recounting of product benefits in the same terminology.

The Institute of Bioengineering and Nanotechnology (IBN) has recently engineered a new hair follicle model that could help discover new drugs or active ingredients for hair regeneration.
