Epigenetics and Aging: A New Player in Skin Care

The cosmetics and skin care industry is constantly developing new products and technologies that aim to slow down the skin aging process. Epigenetic processes play an important role in skin aging. Several new cosmetic products target epigenetic mechanisms and have shown promising results as novel cosmeceuticals.

A Review of Natural Current and Future ‘Body-sculpting’ Cosmetics

A review of select biochemical mechanisms and botanical ingredients that affect the accumulation of fat in the body is presented here. Future approaches to adipose management, such as by gene modulation, also are explored.

How Cosmetics R&D Should Be Using Neuroscience

In this interview, neuroscientist Helen Fisher, Ph.D., describes what companies are not doing to innovate but should be. She will give the Frontiers of Science Award Lecture during the December 2015 SCC Annual Meeting in New York. Cosmetics & Toiletries is sponsoring her talk.

What do We Know About Depigmenting Agents?

This review examines the efficacy and tolerability of agents such as hydroquinone, ascorbic acid and retinol to treat hyperpigmentation disorders. The authors assess the quality of studies as a tool to determine efficacy of depigmenting agents. Along with outcome, they also analyze study design, participant skin type, duration, intervention and statistical significance.

Olay Breakthrough Identifies Traits of ‘Ageless’ Women

The Multi-Decade and Ethnicity (MDE) study reveals biological commonalities among a subset of women who look exceptionally younger than their age.

Gold Microparticles Zap Sebaceous Follicles

Nano shells enable selective photothermolysis to help treat acne.

Shaving and its Effects on Percutaneous Absorption in the Skin*

Despite its being an area of concern for many years, the percutaneous absorption of cosmetics has not been rigorously studied. Additionally, the effects of shaving on this process are relatively unknown. An overview of recent research reveals that more research in this area is required.

Higher Incidence of Nonmelanoma Skin Cancer Found in Asian and Hispanic Women

According to a study presented at the American Academy of Dermatology’s 73rd Annual Meeting in San Francisco, Asian and Hispanic women have an increased risk of developing nonmelanoma skin cancer (NMSC).

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.
