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.

Klotho Gene Variant Found to Enhance Cognition

According to new research from Pennsylvania State University, a variant of the Klotho gene, which relates to lifespan, has been connected with improved cognitive functioning. This pathway has been the focus of recent anti-aging research for cosmetics.

Shiseido to Open Center for Hair Regeneration Research

The Shiseido Cell-Processing and Expansion Center (SPEC) is set to open on May 1, 2014, and will centralize the research and development of regenerative hair treatments.

Molecular Biology in Future Skin and Hair Care

Techniques developed in the field of molecular biology are currently being used to screen cosmeceutical ingredients for skin and hair care applications. New findings are published on a daily basis, providing insight with respect to future innovations for skin and hair health and appearance. Several relevant developments are reviewed here.

Fatty Acid Bile Acid Conjugates—Hypothesis for Skin Anti-aging and Anti-acne Effects

Fatty acid bile acid conjugates (FABACs) have been found to affect skin by enhancing ATP-binding cassette (ABCA1) cholesterol transporter and competitively inhibiting stearoyl-CoA desaturase (SCD1) enzyme. Based on the mechanisms involved, detailed here, the authors developed a new FABAC and tested it in vitro. Results suggest its potential as an anti-aging and anti-acne active.

Columbia Researchers Uncover Touch Sensory Mechanisms

A study published in Nature highlights how a team of Columbia University Medical Center researchers have uncovered the mechanisms behind touch; i.e., how humans feel details and textures.

New Findings for Anti-aging in Hair and Scalp

Anti-aging hair care products address concerns such as thinning, coloring, breakage and drying. At the Cosmetics & Toiletries Summit, an entire hair research track will feature speakers Popescu, Davis, Kazin and Westgate on new biological and chemical considerations for this growing market.

Researchers Identify Pathway to Regulate Telomeres

Cancer researchers at the Salk Institute for Biological Studies in La Jolla, California, have identified a mechanism involved in the lengthening of telomeres; cosmetic researchers often look to this field for novel answers to skin aging.

Carotenoids for Dietary Photoprotection

Sun exposure leads to the production of free radicals in skin and to damage to elastin and collagen, resulting in premature aging. Studies of consuming carotenoid-rich fruits and vegetables have shown lower incidences of skin pathology. Carotenoids are among the most efficient natural scavengers of free radicals and may be used as oral sun protection, as is discussed here.
