Skin care formulations often are enriched with high levels of electrolytic ingredients for various skin benefits. However, these have a negative impact on the viscosity, texture and stability of a system. Described in this article is a multifunctional polymer that is designed to provide excellent electrolyte resistance along with a pleasant sensory profile, as will be shown.

Oxidative stress is a major factor in skin aging, thus a topical compound was designed to increase anti-oxidant coenzyme Q10 (CoQ10) within the body. Described here are in vivo and in vitro studies assessing the compound’s antioxidant and anti-aging capabilities. Results indicate that the modulation of intracellular CoQ10 and its binding proteins appears to protect skin from oxidative damage.

Sea cucumbers, considered a delicacy in East and Southeast Asia, may not be pleasing to the eye but could be pleasing to the complexion. These slippery creatures belong to the animal group of echinoderms, which possess an adaptive feature called mutable connective tissue. While investigating this phenomenon, Maurice Elphick, PhD, and his research team from Queen Mary University of London’s School of Biological and Chemical Sciences not only identified the genes that encode the peptides to make this tissue stiffen and soften, but also have hypothesized that one of these peptides may be used in anti-aging skin care

This article presents skin optics and strategies to design cosmetics that more closely match normal human skin. Topics covered include the spectral reflectance of hemoglobin chromophores, spatial variations and color texture, and optical scattering and translucence. In addition, interference coatings are considered, as are examples of the interplay between home-use devices and agents that affect aging skin.

Effort to improve one’s appearance through the application of skin care heightens a sense of well-being to induce the “look good, feel good” factor. Consumers, however, often do not feel confident about how to apply skin care, suggesting that the application instructions are inadequate. This creates an opportunity for skin care manufacturers to provide application instructions for better product efficacy. A consumer’s application technique contributes to the product’s efficacy in addition to dictating consumer satisfaction on the product’s feel.
