This article reviews the characteristics and structure of hyaluronic acid (HA), then explores how multi-detector gel permeation/size exclusion chromatography (GPC/SEC) and microrheology techniques can be jointly applied to determine the structure-function relationships that support the successful inclusion of HA in cosmetic formulations. Experimental studies are provided to highlight the value of these techniques.

There is likely a variety of causes and contributors to the nebulous consumer term “frizz.” This article attempts to craft a universal definition and then progresses to further examine impacting factors. These discussions focus on methods for quantifying hair properties and assessing the positive impact of commercial hair care products.

The effective delivery of youth-preserving collagen and moisture remains a cosmetic Holy Grail. In response, this study describes a natural microinjection system based on the stinging cells of the Cnidaria sea anemone to effectively puncture the stratum corneum layer and deliver its content—both marine collagen and γ-PGA—into skin, offering a promising new class of solutions to age-old challenges.

In this study, the authors evaluated the effectiveness of a new smart lipid system in stabilizing and delivering carotenes into the epidermis. The system is shown effective in providing free-radical (FR) scavenging at different stages of skin exposure: immediately neutralizing FR present in the skin, blocking FR formation during UV exposure, and accelerating skin recovery after UV exposure.

Mechanisms implied in the skin absorption process and the role of cutaneous metabolism are of increasing interest to cosmetics research. In the present paper, the authors demonstrate how an experimental human skin explant model exhibiting great barrier function and metabolic activities can provide an understanding of what happens to cosmetic actives when they are topically applied.

Around 10-12 years ago, shampoos and conditioners began appearing on the market claiming to be “color safe.” This strongly resonated with consumers. The present article discusses various contributors to the color fade process with a specific emphasis on measurements to quantify and understand color fade.

Emulsions are popular vehicles in skin care due to their affinity for the skin; however, they are thermodynamically unstable systems. This study investigates zeta potential and particle size distribution as potential screening tools to predict instabilities in emulsion-based cosmetic products, to supplement regular accelerated stability testing.
