ZnO Nanoparticles Penetrate but Only Under These Conditions

Zinc oxide (ZnO) nanoparticles are a major component in sunscreens but their ability to permeate skin has remained undetermined. Recent work in Applied Biomaterials identifies the conditions under which they penetrate—notably, not in their nano form as they exist in sunscreens.

[podcast] Author Commentary: Epigenetics in Cosmetics, with Paul Lawrence, Ph.D.

Today, Cosmetics & Toiletries has a special treat for you. Paul Lawrence, Ph.D., co-author on a new three-part article series, shares insights on the potential for epigenetics in cosmetics—not coincidentally, the topic of the series. Listen now!

Water Content, Nanoparticles and Skin Penetration in Brazil: Lindo Maravilhoso!

Water content, surfactants, thickeners, actives, nanoparticles and skin penetration were among the hot topics presented at the biennial XXI COLAMIQC congress of the Latin American and Iberian cosmetic chemists. Held May 14-16, 2013, in São Paulo, technical sessions were paired alongside the FCE Cosmetique exhibition and trade show for both the cosmetics and pharmaceuticals industries.

Glowing Review: Monk Fruit Encourages Epigenetic Well Aging

Monk fruit extract can be used in a holistic approach to target mature skin. It improves physical and emotional well-being by balancing the skin's epigenetic signature to achieve homeostasis. In this article, the effects of a monk fruit extract are tested on dermal structure, hyaluronic acid and skin radiance. Artificial intelligence also is used to assess its emotional impact on the quality of life in mature women.

Do Nanomaterials Penetrate Skin? EUON Commissions Review Study

The EUON commissioned a literature review to explore the potential dermal absorption of nanomaterials. Results found the materials rarely penetrate intact skin, except for ionic silver, but a more standardized approach to testing is needed.

Advanced Methods Measure Skin Penetrants at the Parts-Per-Billion Level

Healthy and intact skin was formerly considered an impermeable barrier designed to shield the living organism from all types of environmental injury, and certainly offering protection from all things chemical. Now skin is recognized as a semi-permeable membrane. Microorganisms cannot penetrate it, but it is pervious to chemicals, selectively allowing molecular passage in and out of the skin.

A High Throughput Method to Predict Skin Penetration and Screen Topical Formulations

This work studies the applicability of a 96-well-based skin-mimetic artificial membrane permeability model to differentiate between topical pharmaceutical and cosmetic formulations. Results are compared with data obtained from in vitro Franz cell permeability measurements and reveal the applicability of this method to assess cosmetic formulation permeation and speed the discovery process.

[podcast] Sunscreen Innovation Act Update: MUsT Test and Penetration Potential

"What’s changed with respect to sunscreen evaluation is ... the test model they are using now is designed for drugs ...and has never been applied previously for the sunscreens," Epstein reports.

Advanced Methods Measure Skin Penetrants at the Parts-Per-Billion Level: Part II

Part I of this Dermatologic View column appeared in the January issue of C&T magazine and described advanced methods to measure skin penetration such as Inductively Coupled Plasma-Mass Spectrometry (ICP-MS) and Atomic Absorption Spectrophotometry (AAS). Here, the authors continue this investigation of advanced methods to measure skin penetration.

Fluorescence Lscm To Assess The Penetration Of Low Molecular Protein Hydrolyzates Into Hair

Fluorescence LSCM to Assess the Penetration of Low Molecular Protein Hydrolyzates Into Hair

The present study uses confocal laser scanning fluorescence microscopy to assess the penetration of protein hydrolyzates into hair. While higher amounts of protein were found in the cuticle, still significant quantities were observed in the cortical parts of hair, and this penetration was enhanced by longer incubation times.
