Neural Networks Predict Material Structures, Behaviors Faster
A recent interview on Phys.org with Argonne National Laboratory Engineer Mark Messner explores how neural networks in AI could be used to predict material structures, given preferred properties, some 2,000+ times faster than standard simulations.
Method/Process
Dermagenetics
The advent of the complete transcribing of the human genome will forever alter our perceptions of skin care, medicine and nutrition. This column is edited by Lawrence A. Rheins, PhD.
Method/Process
Enhancing, Measuring Skin Penetration
Skin penetration is of great interest to personal care formulators for many reasons. Following are a few recent findings.
Method/Process
Predicting the Percutaneous Penetration of Cosmetic Ingredients
While previous algorithms for predicting the skin absorption of permeants was based on in vitro data, the present article proposes a quantitative structure-activity relationship (QSAR) model based on in vivo human data. Here, a set of human in vivo data is described that provides entry into predicting the penetration of cosmetic ingredients.
Method/Process
Testing for Penetration of the Skin Barrier
The skin barrier is described, after which tests and case studies illustrate how to show if actives and other ingredients have or have not penetrated the skin barrier.

Epigenetics Make Sederma Ingredient Shine
Sederma's peptide ingredient is inspired by the K-beauty "glass skin" concept, and is meant to improve skin surface quality and contribute to a dewy complexion.
Method/Process
Ascorbic Acid Penetration: Uncovering Spatial Distribution
A research thesis from the University of Nottingham describes how imaging via time of flight-secondary ion mass spectrometry reveals new insights about spatial distribution and ascorbic acid penetration into the skin.

Don’t Count On Genetics, Sunscreens are the Best Bet
In a podcast with P&G scientists Frauke Neuser, Ph.D. and Rosemarie Osborne, Ph.D.,
Cosmetics & Toiletries
learned about genetic studies in support of the Olay brand, and more. Following is an excerpt.
Method/Process
Genetic Test for Alopecia Approved in Europe
The HairDX Genetic Test for Hair Loss, a genetic baldness test manufactured by HairDX LLC, is now available as a CE Marked product under the European In Vitro Diagnostic Directive.
Anti-aging/Face
Lipotec’s Peptide Regenerates Skin Using Epigenetics
Lipotec has launched PEPROAGETM peptide, which assists in leaving skin smoother, more radiant and visually rejuvenated. The peptide can be incorporated into any anti-aging formulation to help reduce skin regeneration taking place with age or in products designed to rejuvenate the skin.
Literature/Data
Skin Pigment Genetics is More Complex at the Equator
New research published in
Cell
presents genetic findings related to skin pigment diversity and complexity, further supporting the trend for customizable skin care.
Literature/Data
A Dermatological View—Percutaneous Penetration of Amino Acids
Skin care products containing amino acids often promote the benefits conferred on the skin by these molecules. Natural amino acids found in the skin have been found to improve the health of skin through antioxidation, membrane stabilization and increasing skin’s natural moisturizing factor (NMF).
Literature/Data
Genetic Mutations Open Doors to Atopic Dermatitis
Atopic dermatitis may be caused by a single-gene mutation, according to new research published in
Nature Genetics
. Scientists believe the effects of the mutation could be partially corrected through glutamine supplementation.

[podcast] Author Commentary: Epigenetics in Cosmetics, with Paul Lawrence, Ph.D.
Today,
Cosmetics & Toiletries
has a special treat for you. Paul Lawrence, Ph.D., co-author on a new three-part article series, shares insights on the potential for epigenetics in cosmetics—not coincidentally, the topic of the series. Listen now!

Water Content, Nanoparticles and Skin Penetration in Brazil: Lindo Maravilhoso!
Water content, surfactants, thickeners, actives, nanoparticles and skin penetration were among the hot topics presented at the biennial XXI COLAMIQC congress of the Latin American and Iberian cosmetic chemists. Held May 14-16, 2013, in São Paulo, technical sessions were paired alongside the FCE Cosmetique exhibition and trade show for both the cosmetics and pharmaceuticals industries.
Literature/Data
Massive Study Identifies Genetic Indicators for Skin Cancer Risk
The results of a massive study examining some 7,404 cases of squamous cell carcinoma in skin identified genetic associations with this disease, some for the first time.

Do Nanomaterials Penetrate Skin? EUON Commissions Review Study
The EUON commissioned a literature review to explore the potential dermal absorption of nanomaterials. Results found the materials rarely penetrate intact skin, except for ionic silver, but a more standardized approach to testing is needed.
Method/Process
Advanced Methods Measure Skin Penetrants at the Parts-Per-Billion Level
Healthy and intact skin was formerly considered an impermeable barrier designed to shield the living organism from all types of environmental injury, and certainly offering protection from all things chemical. Now skin is recognized as a semi-permeable membrane. Microorganisms cannot penetrate it, but it is pervious to chemicals, selectively allowing molecular passage in and out of the skin.
