Researchers Suggest New Way to Look at Manufacturing Emulsions

Researchers at Harvard's School of Engineering and Applied Sciences (SEAS) have discovered that stabilized emulsions may take months to years to reach equilibrium. This research has important implications for the manufacturing processes used in pharmaceuticals, cosmetics and foods, among other chemical industries.

A Dermatologic View: O/W Emulsions Enriched with Vitamin E

Vitamin E has an important protective function for the entire organism. It is believed that the broad biological activities of vitamin E are due to its ability to inhibit lipid peroxidation and stabilize biological membranes.

Fewer trips to the medspa? Lubrizol's Argireline Amplified Peptide, when applied in combination with Botulinum toxin type-A injections like Botox, can 'keep wrinkles at bay for nearly 8 weeks longer than [the injections] alone.'

Lubrizol's Argireline Amplified Peptide Extends Botox-type Injection Results by 8 Weeks: New Study

Argireline Amplified Peptide, which is produced in accordance to green chemistry principles, has displayed "superior" in vitro activity and muscle relaxation effects compared to the company's original Argireline peptide.

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.

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-aging Effects of Massage and Electricity

Recent research reported in Health Sciences shows skin moisture, facial fat and wrinkle depth improvements by classic facial massage, and increased oxygen uptake by electrical stimulation.

Mechanisms of Tape Stripping and Protein Quantification

In this article, several methods to quantify the protein collected by tape stripping are described, including traditional gravimetric methods as well as novel colorimetric and visible spectroscopic techniques. Further, one colorimetric method is described to effectively determine the keratolytic efficacy of various materials in vivo, suggesting additional roles for this method.

Efficacy of Self-Tanners and Other Topics

Giacomoni reviews skin protection by the use of sunscreens, suntan, and antisun burn preparations. Until recently, the only strategy affording the protection of the skin against the harmful effects of solar radiation was to reduce the number of impinging photons with fabrics, umbrellas, hats, sunglasses or sunscreens.

Researchers from Newcastle University, the Wellcome Sanger Institute and Kings College London have discovered developmental origins of eczema and psoriasis, leading to possible treatment and new research possibilities for other inflammatory diseases.
