How Do Cosmetic Formulas Impact Skin’s Microbiome?

The investigation of skin microbiota under the influence of environmental factors such as cosmetics and from a dynamic perspective has as yet been poorly investigated. Here, metagenomics are used to provide clues.

Hyaluronic Acid Butyric Esters for the Improvement of Skin Functionality

The versatility of hyaluronic acid is connected to not only its size, but also to inherent opportunities within the molecule for multiple bonds and for the differentiated release of bound functional molecules. Here, ester bonds are used to introduce substitutes for the material’s alcohol groups, thus providing elasticizing, moisturizing and antiaging benefits for skin care.

A Great Barrier, Enhanced: A Review of Oral PUFA Supplements for Skin

Skin breakdown is implicated in many areas of health, and transepidermal (TEWL) water loss can indicate the integrity of the skin barrier. This article reviews the literature for evidence of how oral supplementation with polyunsaturated fatty acids (PUFA) could positively impact TEWL, and therefore, skin barrier functioning in healthy individuals.

Uniquely Stable Emulsions Revealed Through Freeze-fracture Transmission Electron Microscopy

Researchers investigated the structures and features of emulsions made with different emulsifiers via freeze-fracture transmission electron microscopy. Potassium cetyl phosphate formed more multi-lamellar spheres than other emulsifiers, and aggregated homo-domains on top of lamellar sheet surfaces and multi-lamellar spheres. These homo-domains are likely to be responsible for the excellent emulsion stability achieved.

SPF Tests Reveal No Ideal In vitro Substrate Exists

In vitro SPF measurements are challenged by reproducibility, repeatability and correlation with in vivo values. Here, the authors assess sunscreen adhesion to the test substrate support, since poor adhesion produces bad results. Surface substrates are characterized by functional group, charge, wettability and surface morphology. Eight w/o and o/w emulsions also are tested. Results indicate an ideal in vitro test substrate does not exist.
