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.

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.

Effects of Occlusive and Semipermeable Membranes on Wound Healing

Skin occlusion is a complex issue. Occlusion usually means the skin is covered directly or indirectly by impermeable films or substances, but certain topical vehicles that contain fats and/or polymer oils may also generate occlusive effects. They speed healing, but can also encourage the formation of bacteria. In the following excerpt, Zhai, MD, and Maibach, MD, review recent studies in various modes and methods of occlusion.

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.

Defining Clinically Relevant Fragrance Allergens: The Challenge (Part I)

Contact allergic dermatitis is a common, and some say pervasive public health problem. The degree to which fragrances and fragranced products contribute to this issue is investigated in a two-part overview by Howard Maibach, MD, and Jurij Hostýnek, PhD, from which the following is excerpted.
