Total Breakdown: Recovering Anti-aging Efficacy After Collagen Fragmentation
When collagen breaks down, the broken fragments can hinder the performance of anti-aging actives over time. This column examines methods by which materials can overcome these aging-related issues in collagen production.

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.

Environmental Stress Panel for Evaluating Diesel Particulate Matter==> download our unique Gene Expression Panels Guide at no cost
Genemarkers, a trusted partner for applying genomic technologies to personal care product development, has launched a new testing service to evaluate how product formulations protect or repair skin in response to diesel particulate matter (DPM).
Anti-aging/Face
Safe and Strategic: Hyaluronic and Retinoic Acid Derivative Allays Aging and Acne
A hyaluronic acid and retinoic acid derivative were developed to combine their individual anti-acne and anti-aging efficacies. In vitro and in vivo testing, described here, showed the conjugate penetrated skin to exert the desired biological activities—in low concentrations and without irritation.
Method/Process
Collagens I and III, and Elastin Activation for Anti-aging
As an alternative to semi-invasive facial rejuvenation techniques, the authors developed an active ingredient to reactivate senescent fibroblasts by stimulating metabolic pathways for collagens I and III, and elastin. The biological activity of the resulting ingredient is investigated here using in vitro models, ex vivo explants and human volunteers.

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.
Method/Process
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.

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.

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."
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.

Screening Botanical Ingredients: Challenges and Opportunities
Botanical ingredients are interesting for their unique and complementary chemical diversities yet they are criticized for these very traits, which make quality assurance, reproducibility and good phytochemical characterization—required for successful high throughput screening, difficult. This article discusses these challenges as well as the benefits of large-scale screenings of botanical extracts that are currently used or developed for cosmetic product development.

AMS Revolutionizes Absorption and Metabolism Studies
Quantification of percutaneous penetration and metabolism of skin care ingredients has seemed daunting; however, new technology provides a ready solution for the problematic arena. Accelerator mass spectrometry (AMS) is a new analytical method that measures a biological response better than the existing technique.
Method/Process
Cosmetic Testing in 2000 and Beyond
Changes in cosmetic testing are being driven by regulation and advanced technologies, such as new in vitro methods, molecular combinational chemistry and skin delivery. Part of the Series: From Test to Claim.
Method/Process
Computerized Measurement and Correction of Color Cosmetics
With a spectrophotometer and computerized color measurement software, the cosmetic chemist can do both basic color quality control and color formulation and correction easily in the lab.

Testing the Fate (and Exposure) of Cosmetic Ingredients
Risk and exposure go hand-in-hand. So when researchers dared to publish a new method to assess the exposure and fate of cosmetic ingredients, we couldn't help but give them exposure, in this review.
