The Hardening Phenomenon in Irritant Contact Dermatitis: Cosmetic Implications

Irritant contact dermatitis (ICD) is common and poses a significant problem in high risk populations including hairdressers, health care workers, metal-working professionals and cleaning specialists.

University Study Advances Understanding of Melanin Formation

Melanin cells can be formed differently than previously thought, a new study from a Swedish medical university has revealed. These results also indicate the discovery of a new type of stem cell.

Researchers Identify Stem Cell Proteins for Hair/Skin Regeneration

Researchers at Rockefeller University have identified two proteins that enable skin stem cells to regenerate themselves to produce either skin or hair.

The arNOX Enzyme: Implications for Intrinsic Aging

This article describes a membrane-bound enzyme found in skin whose activity increases as biological age increases. The enzyme, located on the external surface of fibroblasts and keratinocytes, generates free radicals. The present work identifies the biological mechanism of the enzyme and its relationship to the appearance of aging in skin.

J&J Establishes Online Institute for Naturals Education

Johnson & Johnson Consumer Companies Inc. has established an education-based Web site as a resource for information on the science of natural ingredients in skin care.

Scientists Preserve Membrane Proteins with Nanoparticles

Scientists at the Universities of Birmingham and Warwick have discovered a way to preserve membrane proteins with nanoparticles, enabling the detailed analysis of the structure of molecular functions.

Micron-sized Device Examines Tissue Development

A new device allows researchers to gauge how cells' minute mechanical forces affect cellular behavior, protein deposition and cell differentiation in a three-dimensional, in vivo-like environment.

Dermatologists to Lead Skin Research Institute

A dermatologist-led institute at the University of Miami (UM) Miller School of Medicine has been established to determine the efficacy of skin care products and procedures, and to discover and treat the genes that determine aging, pigmentation and acne.

Biological Cells Designed to "Count" Cellular Events

MIT and Boston University engineers have designed cells that count cellular events. Such cells could be used to count the number of cell divisions for the study of antiaging; to study a sequence of developmental stages, or to serve as biosensors to count exposures to toxins.

Comparatively Speaking: Prokaryote vs. Eukaryote

Cosmetic scientists are interested in the difference between prokaryotes and eukaryotes for preservation and antibiotic development.

Skin's Microbiome Research Reveals Unexpected Bacteria Variety

Researchers have published a report on microbes in the skin, finding a diversity of species much greater than expected. This work could aid in the prevention of skin diseases.

Mitochondrial Nourishment and Protection for Antiaging Effects

Multiple factors affect the integrity of cell mitochondria, leading to loss of cell function, aging and apoptosis. In skin, this is expressed in the form of wrinkles, loss of tone, etc. To combat these effects, the author describes a technology that contains mitochondria-nourishing compounds to deliver antiaging benefits.
