Combining the Salt-Tolerant Plants Limonium algarvense Erben and Polygonum maritimum L. Promotes Synergistic Bioactivities for Enhanced Cosmetic Applications.

ABSTRACT: The demand for natural and sustainable ingredients in dermo-cosmetic formulations has promoted the use of coastal salt-tolerant plants as novel bioresources. This study evaluated aqueous extracts of Limonium algarvense and Polygonum maritimum, two salt-tolerant coastal plants and their mixtures (3:1, 1:1, 1:3, w/w) for antioxidant, metal-chelating, enzyme-inhibitory, antimicrobial and cytotoxic properties. Chemical profiling revealed diverse phenolic signatures dominated by catechin, myricetin and quercetin derivatives, which are known contributors to antioxidant and enzyme-modulating activity. L. algarvense showed the strongest superoxide-scavenging activity (EC₅₀ = 219 µg/mL), while P. maritimum was the most effective hyaluronidase inhibitor (EC₅₀ = 42.9 µg/mL). The
