New Research Highlights Role of Elastin in Stretch Mark Formation

Personal genetics company 23andMe has conducted a genetic study on striae distensae (stretch marks) to identify genetic markers for the skin imperfections and determine why some individuals are more susceptible.

Researchers Identify Molecule Causing Sunburn Pain

A team of researchers from Duke University, Rockefeller University and the University of California San Francisco have identified the gene that causes pain in sunburned skin.

Researchers Uncover Regenerating Properties in Sweat Gland Stem Cells

In his study on sweat glands, Asst. Prof. Krzysztof Kobielak, PhD, MD, and fellow researchers uncovered some interesting findings about sweat gland stem cells that may lead to better treatments for excessive sweating conditions and tissue regeneration.

Skin and Ocular Flora: The Effect of Formulation, Part 2

This second installment of a two-part article reviews the transient and resident microbial populations of the human ocular area and how they alter with age, environment and exposure to antimicrobial agents. Considerations for the formulator of how cosmetic products may affect and be impacted by the flora also are provided.

Traditional Chinese Medicine in Cosmetics

Cosmetics based on traditional Chinese medicine (TCM) are formulated not only using TCM drugs, but also according to cultural theories and principles. This article serves as a review of TCM drug ingredients, history and principles, to assist product developers in understanding how they can be combined for products targeted to this specialized market.

Rosacea: Cause, Triggers and Treatment

Rosacea is a common but little-known disorder of the facial skin that affects an estimated 14 million Americans. In fact, rosacea is becoming increasingly widespread as the baby boomer generation enters the most susceptible ages for its development.

Skin Biology Review: L Neuropeptides, Immunology and More

This article summarizes 31 papers recently published on skin biology. Among the topics are neuropeptides, toll-like receptors and a consideration of allergic reaction versus preservative action in finished products.

The Probiotic Nature of Normal Microflora

Recent studies are revealing that many of their actions are like those of the normal microflora present in the intestinal tract and on the skin and mucous membranes. This article focuses on some similarities between probiotics and normal skin microflora.

In vitro Buffering Capacity of Human Skin Layers*

Previous studies demonstrate that skin buffering capacity can be measured in vitro by applying several concentrations of hydrogen chloride (HCl) and sodium hydroxide (NaOH) on skin and evaluating the pH change pre- and post-dosing. Here, the authors employed this technique to evaluate the buffering capacity of skin layers including intact SC, denuded SC and dermis skin samples.

The Effect of Glycerol on the Water-holding Capacity of Chemically Irritated Skin*

Glycerol is one humectant commonly employed due to its high hygroscopic and hyperosmotic properties. It is used in cosmetics as a moisturizer and in pharmaceutical formulations as an active compound.2 Being naturally present in the skin, glycerol was quickly identified for its role in skin hydration, similar to natural moisturizing factors (NMF).

Corneocare and Comfort Science

At the Skin Forum 2013 event in London, the seven pillars of “corneocare,” were introduced, which targeted: the epidermal tissue at the molecular, cellular and structural level; epidermal function; tactile experience; appearance and sensation. This is one of the first concepts in personal care to close the gap between consumer perception and a scientific approach.
