Evaluating Essential Oils in Cosmetics: Antioxidant Capacity and Functionality
In the present work, the antioxidant capacities of three essential oils derived from basil and thyme were evaluated using a photochemiluminescence (PCL)-based assay. In addition, since the base formulation can affect the antioxidant activity of oils contained therein, ingredient interactions within final formulations were investigated.
Sensory
Intersecting the Senses: Synesthesia to Connect Cosmetics with Emotion
Synesthesia presents a great opportunity for innovative concepts in the cosmetics field. Considering its potential, a study was undertaken to develop a product design model based on synesthetic evaluations of tactile, audio, scent and taste stimuli, and supported by neuroscience techniques and implicit and explicit evaluations.

Efficacy
Image Processing and Analysis to Evaluate the Effects of Porous Polyamide Microspheres in Cosmetics
Described here is an image processing system that compensates for changes in illumination and volunteer position, and two algorithms to quantify skin texture and wrinkles. These methods evaluate skin parameters from a single image without contacting skin. Their abilities are demonstrated here in evaluations of the benefits of porous polyamide ultra-fine powders on skin texture and gloss.
