Literature and Patent Review: Analytical and Test Methodologies 1990-2000, Part II
From more than 40 technical sources published in the 1990s, the author reviews new safety tests and methodologies for evaluating preservatives, sunscreens and a variety of skin parameters.
Method/Process
Evaluating Water Permeability and Occlusion in Wound Dressings and Topical Cosmetics
The present study uses an evaporimeter to measure the degree of water loss from in vitro skin samples covered by occlusive and semi-occlusive wound dressings to serve as a model for determining the effectiveness of occlusive cosmetic formulations. The purpose of this work was to develop a model for determining the effectiveness of occlusive cosmetic formulations.

Skinobs' V2.0 Simplifies and Accelerates Preclinical and Clinical Beauty Testing
Skinobs offers two platforms dedicated to preclinical assays (in-silico, in-tubo, in-vitro or ex-vivo) and clinical evaluation (in-vivo on humans) to reportedly optimize product development in terms of performance, cost, speed and innovation.

Literature/Data
Hair Damage and Repair Literature: Sweet Potato Sochu and Red Clover
Hair thinning and loss; nourishing and bonding treatments; and scalp, curl and color care are among today's top concerns and trends in hair care. As such, we offer the following brief literature review with a look at recent research related to hair repair and damage.
Method/Process
Literature and Patent Review: Analytical and Test Methodologies 1990-2000, Part I
From more than 40 technical sources published in the 1990s, the author reviews methodologies from measuring important variables such as hair condition, bioactivity and irritation of skin and eyes.
Method/Process
Modeling and Targeting Cell Communication, Senescence and Immunoevasion to Support Skin Longevity
The present work sought to develop in vitro models to study the mechanisms of key hallmarks of aging: cellular communication, senescence and immunoevasion. The models were then used to test the efficacy of natural actives targeting these mechanisms.

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.

Beauty Before-and-Afters: How Better Imagery, AI, Social Media and Testing Are Changing the Game
“A high-quality before and after image offers a huge range of benefits. It pushes transparency. You’re no longer stating a claim, you’re demonstrating it."

Quantifying Visual Aspects of Hair
Quantitive claims regarding hair care can be questioned if the results and approaches do not equate to real life occurrences. This article highlights ongoing research efforts that aim to improve our understanding of visual evaluations of hair.
Method/Process
Photoaging and Photodocumentation
Techniques to photograph or image skin photodamage have reached new levels of sophistication. This survey discusses clinical grading, light imaging techniques, video-microscopy and three-dimensional in vivo measuring systems.
Method/Process
DNA: Hard Evidence of Cosmeceutical Claims
To support finished product or raw material claims these two in vitro methods—the Affymetrix microarray and the Taqman Real Time Polymerase Chain Reaction (PCR)—measure the up-regulation or down-regulation of genes.
Method/Process
In Vivo Quantitative Evaluation of Gloss
A real time polarization analysis technique is described that differentiates components of scattered light in video images and enables in vivo quantitative evaluation of gloss from hair and skin during quality control and claims substantiation.
Method/Process
BioScreen Offers Asian Panels
Beginning fall 2006, BioScreen will begin offering Asian subject panels.

DNA: Hard Evidence of Cosmeceutical Claims
To support finished product or raw material claims these two in vitro methods—the Affymetrix microarray and the Taqman Real Time Polymerase Chain Reaction (PCR)—measure the up-regulation or down-regulation of genes.
Sun Protection
Determination of the In Vitro SPF
A ring test at six European test centers showed that SPF evaluations with good reproducibility and comparability could be obtained by an in vitro protocol measuring either transmittance or erythema-effective irradiance of product samples applied on PMMA plates.

Characterization of Multilamellar Vesicles for Cleansing Applications
In the present article, the authors characterize a multilamellar vesicle (MLV) system used in personal care and verify its structure via X-ray scattering, rheology and fluorescence microscopy. This enabled the study of MLV formation to investigate bulk rheology characteristics. The results are presented here as application-relevant properties.
