Science
Mechanism of Action
This ingredient primarily functions by imparting astringent and toning effects, aiming to revitalize the skin's appearance. Its antioxidant capabilities are attributed to a rich composition of polyphenols, flavonoids, and tannins. Notably, mature leaves are significant sources of ascorbic acid, phenolics, and compounds exhibiting strong free radical scavenging activity (demonstrated via ABTS and DPPH assays). Key constituents identified within the leaf extract include malic acid, epigallocatechin gallate, quercetin, pyrogallol, and mandelic acid, all recognized for their diverse beneficial properties.
