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.
