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.
A running joke has developed at past hair science meetings that the hair research world comprises two camps– “The Friends of the Follicle,” whose focus resides in the biology, and “The Dead Fiber Club,” whose interest lies with the complex material science of this remarkable substrate.
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).
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.
In recent years, new agents, especially from plants, have been discovered and extracted to test for their depigmenting effects in vitro and in vivo. This article reviews these most recent skin whitening agents of interest, whose efficacy, mechanism and safety have been tested.
Researchers from Rapid Precision Testing Laboratories have found that UV nail lamps are safe and to not cause cancer. After the lamps became popular in the last few years for curing non-chip gel nail polish, many began to question their safety.
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.
The Institute of Bioengineering and Nanotechnology (IBN) has recently engineered a new hair follicle model that could help discover new drugs or active ingredients for hair regeneration.
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.
The Michigan chapter of the Society of Cosmetic Chemists (SCCMI) is holding their first educational event, “The Molecular Biology of Skin,” on Sept. 11, 2013, at the Amway Grand Hotel in Grand Rapids, MI USA.
