SKIN HYDRATION


drought periods of up to 400 years may occur, an extraordinary natural phenomenon occasionally takes place, known as the ‘flowering desert’ miracle. This event occurs following rare episodes of


rainfall that trigger the massive germination of dormant seeds in the soil, temporarily transforming the desert landscape into a mosaic of flowers and vegetation. One of the most representative species of this phenomenon is Cistanthe grandiflora, commonly known as the Atacama flower. This plant has evolved under extreme environmental conditions characterized by minimal precipitation, intense solar radiation, and large thermal fluctuations. As a result, it has developed highly specialized physiological and ecological adaptations that enable survival in one of the most arid environments on Earth. Among these adaptations, efficient water


management is essential. In such a restrictive environment, plants must tightly regulate water uptake, distribution, and retention at the cellular level in order to maintain functionality. This requires not only structural adaptations but also finely tuned molecular mechanisms that control water homeostasis. In this context, aquaporins play a central


role. In plants, these membrane channel proteins are not limited to water transport but are increasingly recognized as key regulators of cellular homeostasis and stress adaptation. They

This positions such species as valuable biological models for understanding controlled hydration mechanisms at the cellular level. In addition to membrane-level regulation,


several species within the genus Cistanthe exhibit crassulacean acid metabolism (CAM), a photosynthetic adaptation that enhances water- use efficiency. This pathway allows nocturnal CO₂ uptake


and daytime stomatal closure, reducing water loss under arid conditions. Importantly, CAM expression can be facultative or constitutive depending on environmental stress, providing metabolic flexibility that further supports survival in highly variable desert environments.10 Altogether, these adaptations reflect the

facilitate the movement of water and small solutes while also participating in signaling processes that enable plants to respond dynamically to environmental challenges such as drought and salinity. This multifunctional role highlights the importance of aquaporin-mediated regulation in maintaining cellular water balance.11 Although specific data on Cistanthe grandiflora


remain limited, plants adapted to extreme environments are known to rely on highly efficient aquaporin-mediated water regulation systems.


remarkable capacity of Cistanthe grandiflora to dynamically regulate water under extreme conditions, making it a compelling model of biological resilience and an inspiring source for the development of advanced hydration strategies.


Cistanthe Grandiflora stem cell extract: smart hydration system Building on the remarkable adaptive strategies of Cistanthe grandiflora, a stem cell-derived extract from this ephemeral plant has been developed as a biotechnological active ingredient. Thanks to plant stem cell culture technology, it


is possible to obtain the bioactive compounds of this species without the need to harvest it directly from its natural environment, thereby preserving its
