Mar 4, 2014
Researchers from the Drexel University College of Medicine have established a clearer relationship between Staphylococci bacteria and the conditions atopic dermatitis (AD) and eczema.
Hypersensitive Skin: Classification and Potential Risk from Cosmetic Formulations
Feb 21, 2014
Considering the potential for reactions between cosmetics and hypersensitive skin, the present article will focus on this skin type; first by outlining mechanisms of type I and IV hypersensitization, then by focusing on type I immunogenic vs. non-immunogenic urticaria. Potential urticariogens in cosmetics are considered, and suggestions for future direction are given.
New Findings and the Impact of Infant Skin Microbiota on Product Development
Feb 14, 2014
Recent studies demonstrate that the skin microbiome of infants actively changes during the first year of life, along with evolutions in skin structure, biochemical composition and function. These dynamics in the development of a healthy skin microbiome must be taken into consideration when designing products for baby skin care.
Growth, Senescence, Canities, Bleaching and Anti-aging in Hair
Jan 24, 2014
The continued use of hair bleaches and dyes to combat the onset of gray hair creates a greater demand for hair products that deliver the desired effect while facilitating repair. Molecular biology promises new strategies in combating the aging process of hair cells, with the paradigm shift toward understanding the living component of the hair follicle.
The Latest in Whitening Agents
Jan 13, 2014
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.
The Effect of Glycerol on the Water-holding Capacity of Chemically Irritated Skin*
Jan 13, 2014
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. 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
Oct 1, 2013
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.
New Research Highlights Role of Elastin in Stretch Mark Formation
Aug 28, 2013
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.
Study finds UV Nail Lamps to Be Safe
Aug 28, 2013
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.
Smoking and Premature Aging
Jul 1, 2013
Multiple environmental factors are associated with facial aging; evidence suggests that smoking 20 cigarettes per day is equivalent in effect to almost 10 years of chronological aging. Therefore, lifestyle recommendations to stop or delay facial skin aging are also very useful in promoting public health.
Determining the Keratolytic Activities of Benzoyl Peroxide, Retinoic Acid and Salicylic Acid In vivo
Jul 1, 2013
Keratolysis is the separation or loosening of the stratum corneum (SC), and is part of the natural cycle of skin renewal and regeneration. Disordered keratolysis, resulting in skin overgrowth or excessive desquamation, is responsible for various skin disorders.
The Professional Face of Skin Care
Jun 1, 2013
Skin care practice is often culturally ingrained and guided by ritual. There are numerous professions concerned with the skin: the dermatologist, the dermatology nurse, the esthetician and even the skin care sales assistant. Their expertise, approach, perspective and degree of authority in skin care decision-making is different. Yet, finding common denominators is beneficial, and all of these professionals are skin care consumers themselves.
Sea Cucumber Peptides to Affect Collagen
Dec 12, 2012
Sea cucumbers, considered a delicacy in East and Southeast Asia, may not be pleasing to the eye but could be pleasing to the complexion. These slippery creatures belong to the animal group of echinoderms, which possess an adaptive feature called mutable connective tissue. While investigating this phenomenon, Maurice Elphick, PhD, and his research team from Queen Mary University of London’s School of Biological and Chemical Sciences not only identified the genes that encode the peptides to make this tissue stiffen and soften, but also have hypothesized that one of these peptides may be used in anti-aging skin care
