Résumé
This thesis explores the evolution of skincare approaches to aging, moving from a primarily corrective perspective to a strategy focused on prevention. This shift informs the development of an innovative product concept inspired by this vision. The analysis begins with a thorough examination of the histophysiology of the skin and the complex mechanisms underlying skin aging. The focus then shifts to hyaluronic acid, an ancestral key ingredient and essential ally for skin health. Its numerous benefits and applications, both in cosmetics and aesthetic medicine, are explored in detail. Furthermore, this manuscript highlights the crucial importance of a close synergy between science and marketing in shaping the future of beauty. It advocates for redefining the contours of anti-aging care by leveraging the latest scientific discoveries to meet the evolving and increasingly demanding aspirations of consumers. A new, holistic, and avant-garde approach to anti-aging is proposed. Inspired by the latest advances in cosmetic procedures, this research, at the crossroads of tradition and innovation, paves the way for a new era for visibly healthier, deeply revitalized, and youthful radiant skin. The development of a new generation of anti-aging cosmetic products embodies this ambition.
