Eye Color Cosmetics and Contact Dermatitis

Following is an overview of research correlating, even at trace amounts, raw materials present in eye area color cosmetics with contact dermatitis.

Eye Area Problems: Puffiness, Bags, Dark Cicles and Crowsfeet

To develop active treatment products that address eye area problems, i.e., puffiness, bags, dark circles and crowsfeet, the cosmetic chemist must better understand the biology of the eye area, the effects of aging and chronic sun exposure and how to select ingredient that will provide stuitable benefit.

Researchers Link DNA Repair Protein With Increased Skin Cancer

Researchers from the University of North Carolina at Chapel Hill have established a connection between a repairing protein and times of the day with an increased risk of skin cancer.

Assessing the Safety of Parabens: Percutaneous Penetration and Risk Analysis

In cosmetics, parabens are widely used due to their low cost and efficacy. In recent years, however, some reports have claimed that these materials exhibit estrogenic activity, which has led to attempts to replace them in formulations. This article reviews penetration studies of parabens spanning the past 20 years to determine whether they pose a risk to human health.

A Dermatological View—The Controversial Influence of Moisturizers on Skin Water Barrier

As is described here, moisturizers can influence the properties and structure of corneocytes by influencing the SC and consequently, the skin water barrier function. This hydrative influence of moisturizers could be beneficial as well as destructive toward skin barrier function.

Researchers Connect FADD Protein to Skin Inflammation

Researchers from the University of Cologne, Ghent University and the German Sport University Cologne have identified the protein that may stop necroptosis in keratinocytes, thereby preventing skin inflammation.

Researchers Disprove Resistance With Antibacterial Soap Use

A collaboration of researchers have reported that use of antibacterial soaps does not lead to antibiotic or antibacterial resistance.

Comparatively Speaking: Keratinocyte vs. Corneocyte

Here, industry expert Tony O'Lenick asks Kelly Dobos to explain the difference between keratinocytes and corneocytes. Many skin care products target either keratinocytes or corneocytes; therefore, understanding their differences and the basic structure of human skin is important for formulators.

Study Discovers Mechanism Behind Caffeine's Inhibition of UV-induced Cancer

Researchers at Rutgers have suggested that topical caffeine may help lower the risk of UV-induced skin cancer.
