Although nanomaterials have been used in cosmetics for some time, consumers believe they may constitute a health risk due to their possible penetration into the skin. The present article evaluates the benefits as well as the skin penetration of nanoparticles used in cosmetics.

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.

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.

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.

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.

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

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.

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.

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.

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.

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.
