Olay Breakthrough Identifies Traits of ‘Ageless’ Women
The Multi-Decade and Ethnicity (MDE) study reveals biological commonalities among a subset of women who look exceptionally younger than their age.

Beating the Damaging Effects of Heat on Hair
Heat treatments are among the more popular methods for achieving straight hair, yet their high temperatures are quite damaging to the hair’s structures. Learn about the damaging effects and suggested solutions for repairing heat-damaged hair.

Hidden Hair Damage and the Importance of Multiple Tests
It is of paramount importance for hair researchers to know the history of hair at the time of applying a treatment. The lack of such knowledge can create misleading results. Thus, a stress-strain test in both dry and wet states can provide a rapid means to check the reliability of the information collected, as is shown here.
Literature/Data
Shaving and its Effects on Percutaneous Absorption in the Skin*
Despite its being an area of concern for many years, the percutaneous absorption of cosmetics has not been rigorously studied. Additionally, the effects of shaving on this process are relatively unknown. An overview of recent research reveals that more research in this area is required.

EC, EFSA to Examine Endocrine Disruptors
The European Commission Directorate General for Health and Food Safety will hold a one-day conference in Brussels on June 1, 2015, to determine the criteria to identify endocrine disruptors and the European Food Safety Authority will participate.

Analytical Techniques for Hyaluronic Acid Formulation
This article reviews the characteristics and structure of hyaluronic acid (HA), then explores how multi-detector gel permeation/size exclusion chromatography (GPC/SEC) and microrheology techniques can be jointly applied to determine the structure-function relationships that support the successful inclusion of HA in cosmetic formulations. Experimental studies are provided to highlight the value of these techniques.

Biomimetic vs. Traditional Skin Moisturization: An In vivo Comparison*
To alleviate skin dryness, humectants and occlusive substances are traditionally used, mostly in combination. A third, relatively recent approach is biomimetic, i.e., active ingredients with lamellar structure containing skin-identical lipids. The aim of this study was to determine whether a biomimetic cream could deliver superior moisturization to human volunteers, compared with a conventional moisturizer containing petrolatum and mineral oil.

SYN-Coll: Power Anti-aging with a Collagen-boosting Peptide
Skin aging, in particular when induced by chronic UV exposure, leads to degenerative changes in the skin. Ultraviolet light also increases metalloproteinase activity. This leads to a breakdown of collagen at a higher rate than with just regular aging. If not taken care of, these fine lines become visible to others.
Efficacy
Smart Lipid-carotene System for Targeted Free Radical-Scavenging
In this study, the authors evaluated the effectiveness of a new smart lipid system in stabilizing and delivering carotenes into the epidermis. The system is shown effective in providing free-radical (FR) scavenging at different stages of skin exposure: immediately neutralizing FR present in the skin, blocking FR formation during UV exposure, and accelerating skin recovery after UV exposure.

A Novel Explant Model for Skin Delivery Assessment
Mechanisms implied in the skin absorption process and the role of cutaneous metabolism are of increasing interest to cosmetics research. In the present paper, the authors demonstrate how an experimental human skin explant model exhibiting great barrier function and metabolic activities can provide an understanding of what happens to cosmetic actives when they are topically applied.
Method/Process
Zeta Potential and Particle Size to Predict Emulsion Stability
Emulsions are popular vehicles in skin care due to their affinity for the skin; however, they are thermodynamically unstable systems. This study investigates zeta potential and particle size distribution as potential screening tools to predict instabilities in emulsion-based cosmetic products, to supplement regular accelerated stability testing.
Efficacy
Hair as a Test Substrate
Hair is a distinctly variable material, and the nature of this substrate can have a major impact on laboratory test results. This article discusses hair as a laboratory substrate to provide guidance on minimizing variability and creating optimal test conditions.

IFSCC 2014 Explores Social, Psychological and Sensorial Aspects of Beauty
As one might expect from an event centered around beauty and staged in Paris, the 28th Congress of the International Societies of Cosmetic Chemists (IFSCC) was nothing less than fabulous. However, the glamour and fanfare was deeply rooted in science.
