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.

Reports are circulating that South Korea's Ministry of Agriculture, Food and Rural Affairs (MAFRA) has published a "5 Year Plan for Animal Welfare" that establishes a plan to phase out animal testing for cosmetic products and eventually cosmetic ingredients.

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.

Hair is a distinctly variable material, and the nature of this substrate can have a major impact on laboratory test results. This article discusses hair as a laboratory substrate to provide guidance on minimizing variability and creating optimal test conditions.

Abnormal epidermal turnover in psoriatic skin impairs its barrier function and tissue repair capabilities. Therefore, studies of hyperkeratinization and hyperproliferation have been conducted to better understand the disease. Here, the administration of heavy water and a tape-stripping method are used to measure skin protein turnover in psoriatic skin and surrounding tissues. Results demonstrate benefits over other proliferation measurements.

In any sun protection evaluation method, an irradiation step is required to determine the photostability of the UV filters in a product. The aim of this study was to identify key parameters involved to improve this UV exposure. Here, the authors consider temperature at the substrate surface, air flow influence and beam uniformity during UV exposition.

A previous article discussed traditional measurements to assess the properties of hair spray products. However, the properties of polymer films deposited by these products are not constant and can be altered by both formulation means and environmental conditions. This article highlights additional useful measurement techniques for characterizing these film properties.
