Darker Skin Prone to Vitamin D Deficiency

While individuals having darker colored skin are more protected against UV, a new study found they also are more prone to vitamin D deficiency.

Scientists Find Mitochondrial Complex II Declines with Age

A new study found the activity of mitochondrial complex II, which is a key metabolic enzyme found in human skin cells, declines as humans age, .

Endpoint. ‘Skin’teresting Developments

By 2021, skin care is expected to reach U.S. $154 billion. Futurists making this market prediction must have factored innovation into the equation. So, where will it come from?

Facial Fat as a Key Anti-aging Target

Facial morphology is associated with subcutaneous adipose tissue (sFAT), dermal elasticity and the dermal layer structure. Thus, a fibroblast/adipocyte co-culture was developed to examine the interactions between these entities. Once their mechanisms were identified, a tiencha, or sweet tea, extract was tested for its effects on adipocytes and potential to improve facial morphology.

Connecting the Dots Between Microbes

Obviously, microbes have been around forever; just ask Ötzi, the Copper Age Man. The point being: if you can’t beat ‘em, join ‘em. It appears the industry is taking this to heart—and skin.

Controlling MicroRNAs to Fight Skin Senescence

The present article reviews the roles of microRNA in skin senescence, then explores how an extract of Plantago lanceolata, obtained through plant cell culture technology, regulates the genetic expression of specific microRNAs. Signs of senescence relating to dermal quality, density and thickness, and the appearance of age spots were assessed.

Anti-aging Effects of Massage and Electricity

Recent research reported in Health Sciences shows skin moisture, facial fat and wrinkle depth improvements by classic facial massage, and increased oxygen uptake by electrical stimulation.

New Findings in French vs. Brazilian Skin

A new study from the University of São Paulo, Chanel and EVIC, pending publication in the British Journal of Dermatology, shows that French women's skill is better hydrated than Brazilian women's.

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.
