Preservative Predicaments in Facial Skin Care

Preserving skin care products has become challenging because of attacks by special interest groups, which often lead to negative consumer perceptions. As these assaults on preservatives—some scientifically sound, some not—continue, the industry must look for new preservation methods to gain acceptance.

Patent Pick: Growing 3D Skin Predictions

A product manufacturer's reputation is perhaps its greatest asset, and growing numbers of cosmetic consumers with sensitive skin only raise the product development bar. That's where patented inventions such as this, a 3D skin model, can ensure product safety and support cosmetovigilance initiatives.

To produce a stable emulsion, an emulsifying agent can be added to the oil and water that will either act as a barrier to alter the droplet coalescence rate, or create an interfacial film that can produce repulsive electrical forces between approaching droplets.

Zeta Potential and Particle Size to Predict Emulsion Stability

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.

Quantifying Well Aging: A Mathematical Sketch to Predict Age

There is no biological evidence to explain why some individuals look older or younger than they really are. This work sought to quantify the cutaneous characteristics of well aging based on focus group input, word clouds, biometric measurements and more.

A High Throughput Method to Predict Skin Penetration and Screen Topical Formulations

This work studies the applicability of a 96-well-based skin-mimetic artificial membrane permeability model to differentiate between topical pharmaceutical and cosmetic formulations. Results are compared with data obtained from in vitro Franz cell permeability measurements and reveal the applicability of this method to assess cosmetic formulation permeation and speed the discovery process.
