Atopic Dermatitis—Part I: Early Research and Causes

This column is the first in a two-part series on atopic dermatitis (AD), a common, chronic inflammatory skin disease. Here, the authors will review early research and delve into causes of AD to support a future column on AD criteria and investigation.

Research Suggests a Need for After-sun Sunscreen

According to a report from Yale, the damage caused by UV radiation continues hours after the sun exposure occurred. In the described study, melanocytes generated CPDs both immediately and hours after UV exposure had ended. This may suggest the need for “evening-after” sunscreen, designed to block energy-transfer.

Researchers Link Skin Cell Molecule with Immune Response

Researchers from Melbourne, Monash and Harvard Universities published new findings on how immune cells in the skin sense foreign invaders and react with inflammation or alergic reactions to protect the body.

ROS Suspected to be Beneficial to Wound Healing

Free radicals might not be all bad, according to researchers from the University of California, San Diego. Andrew Chishold, PhD, and his fellow researchers found reactive oxygen species (ROS) to be beneficial to wound healing.

Sunscreen Across the Spectrum?

Newer to the scene are products that protect skin against infrared radiation, as well as research on the effects of high energy visible and visible light. In response, at the C&T Summit, Jürgen Lademann, PhD, will present "Should Sunscreens Protect Across the Whole Solar Spectrum?"

Olay Conducts Clinical Trial On Pollution's Skin Impact

Pollution is bad news for the skin regardless of lifestyle choices, according to a study by Olay scientists and Beijing's General Hospital of the Air Force. The two collaborated to study environmental factors and skin in a city well known for its poor air quality.

Researchers Find Fat Burning Action in Adenosine

Researchers from the University Hospital Bonn have reported that adenosine may stimulate brown fat to burn off undesirable white fat cells.

An Approach to Develop Cosmetics for Multi-tonal Brazilian Skin

In Brazil, people have many different colored skin tones, and women often struggle to match makeup shades to their skin color. This paper describes an exploratory study of hundreds of volunteers that was conducted to understand Brazilian women's skin color, ultimately to develop a makeup line for this widely diverse market.

Skin Aging at the Functional Proteomics Level: Elastin as a Marker

There is general agreement on elastin’s role in skin health, aging and appearance, but no method has yet elucidated how it degrades with aging when challenged by sun exposure or other means. This paper reviews two inconsistent theories in the literature, degradation and buildup, and highlights potential methods to marry the two. It also suggests proteomics as a method for further investigation.

Nature-derived Care for Sensitive and Difficult-to-treat Skin Types

A number of consumers can be classified as having difficult-to-treat skin types, being both dry and oily and prone to periodical inflammation in specific areas. New active ingredients derived from nature provide gentle yet efficacious solutions to address these needs. These skin types and solutions are addressed herein.

Stanford Study Connects Stem Cell Protein to Human Hair Color

According to a study by Stanford University School of Medicine, a molecule crucial to stem cell functioning plays a major role in controlling human hair color.

Literature Review: Damage, Growth and Conditioning in Hair

This survey of recent literature relates to assessing hair damage, reducing dye allergy, increasing and inhibiting hair growth, cleansing and conditioning hair, and more. The papers are presented as food for thought in the early stages of the product development process, and may warrant deeper investigation.
