Tactile Sensory Evaluation: an essential tool to evaluate skin-product interaction

Résumé

CONTEXT. Today’s consumers are looking for environmentally friendly cosmetic products without making any concessions on their performance [1] including sensory qualities and efficiency. In such a competitive sector as cosmetics, the development of innovative tools to gain time and to better understand the product application and the skin-product interaction is therefore crucial [2–3]. OBJECTIVE and METHODS. Here, the aim is to present a tactile sensory evaluation approach for skincare products and to introduce a case study of how combining different approaches such as sensory analysis, physico-chemical methods and biometrology are of key interest to whom aim to understand the complex mechanisms for tactile perception induced by product application on the skin surface. RESULTS. A series of either basic and original methods using human skin as well as non-biological surfaces mimicking the human skin were successfully tested with very good reproducibility of the spreading behavior. The study allowed deepening both knowledge and understanding of skin interactions with its environment, after application of dermocosmetic emulsions. In addition, results clearly highlight how emulsion composition do influence the penetration and absorption in the human skin, thus bringing keys for better understanding the spreading behavior. Finally, the developed original tools are of great interest to study the efficacy of new formulas on skin and help performing standardized measurements as well as solving the logistic and safety problems of in vivo studies. CONCLUSION. Undoubtedly, in vivo tactile sensory evaluation is an essential tool for cosmetic products characterization. In a fast-growing society the development of innovative instrumental and fast alternative methods highly correlated to in vivo studies represents a promising way to control the sensory perception of new products which is very important for their acceptability by consumers.
