Unexpected Lessons in Dermatotoxicology: De minimis Magnesium++

Traditional dermatotoxicologic investigations focus on dermatitis as well as potential systemic effects1 but rarely have they focused on trace ions. The following lesson opens new avenues of thought and investigation for intimate care product developers, since the trace ions described may dramatically impact the end product.

Researcher Develops Lauric Acid Anti-acne 'Bombs'

In recent research from the University of California, San Diego, Jacobs School of Engineering, a smart delivery system coupled with lauric acid has been shown to deliver nano-scale liposome "bombs" to kill acne bacteria.

Researchers Reverse the Age of Cells with Induced Stem Cells

A team of North American researchers have demonstrated a reversal of the developmental aging of normal human cells with induced pluripotent stem cells.

Is Asian Skin Really Different from Black or Caucasian Skin?

It often is claimed, particularly in East Asia, that Asian skin is more sensitive than Black or Caucasian. To explore this claim, the author investigates the current literature in this review and concludes there are two aspects being overlooked: the skin’s capability to cope with perturbations and the route of penetration.

Gene Variable Identified to Predict European Hair Curliness

Researchers at the Queensland Institute of Medical Research have identified a link between a gene and the degree of curliness in hair of European descent. This finding could be applied in forensic investigations or be used to manipulate hair with proteins.

Kangaroo DNA Repair Enzyme Could Prevent Skin Cancer

Scientists in Australia and Austria are studying a DNA repair enzyme found in kangaroos that reportedly fights the damage caused by skin cancer.

Study of Twins Correlates Aging with Genetics

While up to 40% of aging-related changes in skin are due to non-genetic factors, a recent study found a high correlation between the photodamage scores among both monozygotic (identical) and dizygotic (fraternal) twins.

The Effects of Showering Too Often, Too Hot and Too Long

This article is about something that anyone with teenage children will recognize: the fact that while you cannot get pre-teens to go into the shower, you cannot get teenagers out of the shower. However, when their showering is too often, too hot and too long, they are steam-stripping their skin.

Anti-inflammatory Action Found in Skin's Microflora

Researchers at the University of California at San Diego have provided a molecular basis to understand the "hygiene hypothesis," the theory that the lack of childhood exposure to infectious agents and microorganisms decreases their susceptibility to disease, which suggests therapeutic approaches to inflammatory skin diseases.

Skin Penetration of EGCG, Quercetin Examined

A recent study in Skin Pharmacoloy and Physiology examined the delivery of epigallocatechin-3-gallate and quercetin from green tea and Ginkgo biloba extracts into the skin from cosmetic formulations.

Microdermabrasion to Remodel Damaged Skin

In a recent study, microdermabrasion using a coarse grit hand piece on photo-damaged skin was found to induce a remodeling cascade in skin similar to that seen in incisional wound healing.

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.
