Terminalia Chebula for Preventive and Restorative Anti-aging Benefits*

Jun 24, 2015Ratan K. Chaudhuri and Zoia Lascu, Sytheon Ltd., Boonton, NJ USA; Francois Marchio, Sytheon SARL, Boulogne Billancourt, France

This paper examines a tannin-enriched Terminalia chebula extract. Discussed are its mechanisms for preventative and restorative anti-aging effects, and skin pigmentation control. A pilot clinical study further confirms the extract’s bioactivity to reduce wrinkles and pigmentation. Improvements in yellowish skin tones also were observed, likely due to glycation reversal.

Hidden Hair Damage and the Importance of Multiple Tests

Jun 1, 2015Crisan Popescu, Ph.D.*, Kao Germany GmbH, Darmstadt, Germany

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.

Analytical Techniques for Hyaluronic Acid Formulation

May 15, 2015John Duffy, Ph.D., and Bassem Sabagh, Ph.D., Malvern Instruments, Worcestershire, UK

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.

Defining and Controlling Frizz

Apr 20, 2015Trefor Evans, PhD, T.A Evans Inc., Princeton, NJ USA

There is likely a variety of causes and contributors to the nebulous consumer term “frizz.” This article attempts to craft a universal definition and then progresses to further examine impacting factors. These discussions focus on methods for quantifying hair properties and assessing the positive impact of commercial hair care products.

Sea Anemone Delivery of Collagen and γ-PGA for Anti-aging Benefits

Apr 7, 2015Yossi Tal, PhD, Einav Danon and Amir Toren, PhD, StarletDerma Ltd., Caesarea, Israel; and Alain Khaiat, PhD, Seers Consulting, Singapore

The effective delivery of youth-preserving collagen and moisture remains a cosmetic Holy Grail. In response, this study describes a natural microinjection system based on the stinging cells of the Cnidaria sea anemone to effectively puncture the stratum corneum layer and deliver its content—both marine collagen and γ-PGA—into skin, offering a promising new class of solutions to age-old challenges.

Smart Lipid-carotene System for Targeted Free Radical-Scavenging

Mar 30, 2015G. Rodríguez, M. Cócera, L. Barbosa-Barros, E. Fernández, A. de la Maza and O. López,

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

Mar 1, 2015Lucie Duracher, PhD; Lene Visdal-Johnsen, PhD; and Alain Mavon, PhD; Oriflame Cosmetics AB, Skin Research Institute: Sandrine Kurdykowski, PhD; and Pascal Descargues, PhD; Genoskin

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.

Zeta Potential and Particle Size to Predict Emulsion Stability

Nov 19, 2014A.P. Gasparelo†, ‡; C. Dal Pizzol†; P. Fernanda Campos de Menezes†; R.V. Knapik†; M.A. Trindade Costa†; M.R. Machado Prado‡; and C.E. de Oliveira Praes†; † Grupo Boticário, São José dos Pinhais, Brazil; and ‡ Faculdades Pequeno Príncipe, Curitiba, Brazil

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.
