Effective release of Eryngium maritimum L. callus extract via encapsulation in multilayered liposomes for skin delivery.

AIMS: This study aimed to evaluate the potential of Eryngium maritimum L. (EM) callus media filtrate (ECMF) for enhanced skin delivery through multilayered liposomes (MLs). MATERIALS & METHODS: ECMF was applied to human skin cells to assess its antioxidant, anti-inflammatory, and skin barrier-enhancing properties. ECMF was encapsulated in MLs to enhance delivery efficiency, creating a formulation called Cellbiome. Clinical trials involving human participants were conducted to compare its effects with traditional formulations, assessing parameters such as skin density, hydration, elasticity, and wrinkle reduction. RESULTS: Cellbiome significantly improved skin density and moisturization, outperforming conventional formulations. ML encapsulation facilitated deeper penetration of active ingredients beyond the stratum corneum, leading to synchronized improvements in multiple skin parameters, including elasticity, wrinkle reduction, and overall skin health. Transcriptomic and metabolomic analyses further confirmed ECMF's bioactivity and its role in skin improvement. CONCLUSIONS: ML-based formulations, such as Cellbiome, offer superior efficacy in skincare applications compared to conventional methods. This study underscores the importance of advanced delivery technologies in cosmetics and highlights the need for further research to optimize the benefits of natural extracts like EM for human skin, potentially advancing dermatological and cosmeceutical applications.
