Harnessing Cistanthe grandiflora for smart skin

ABSTRACT

The concept of skin hydration has evolved from a passive approach toward more advanced strategies based on so-called ‘intelligent hydration’, which is aimed at modulating the expression of key proteins involved in water balance, such as aquaporins. In this context, current research focuses on the development of active ingredients capable of stimulating the skin’s intrinsic physiological mechanisms. Inspired by the adaptive strategies of plants that thrive in extreme environments, biologically active metabolites have been identified with the ability to induce aquaporin expression. Through advanced biotechnological processes, such as the isolation and cultivation of plant stem cells, it is possible to extract, optimize, and concentrate these bioactive compounds, whose availability is limited through conventional agricultural methods. The topical application of these metabolites promotes the regulation of aquaporins in the epidermis, leading to a significant improvement in skin hydration and overall skin wellbeing. This approach represents a new generation of dermocosmetic solutions based on the activation of endogenous processes and the optimization of the skin barrier function

Skin hydration is one of the most fundamental determinants of cutaneous physiology, influencing elasticity, barrier integrity, enzymatic activity, and visual appearance.¹ Adequate water content within the epidermis is essential for maintaining normal desquamation processes and optimal mechanical properties of the skin.²
