Science
Mechanism of Action
This extract, commonly known as Burdekin plum, functions through its high concentration of phenolic compounds, including anthocyanins, cyanidin-3-glucoside, ellagic acid, gallic acid, catechin, and quercetin. These compounds provide robust antioxidant activity, combating free radicals to mitigate early signs of aging. In vitro studies further indicate anti-inflammatory effects. The extract aids in hydration by drawing water to the skin's surface and contributes to a more uniform skin tone by inhibiting melanin production and increasing cellular turnover. Additionally, it promotes collagen synthesis, enhancing skin's elasticity and firmness.

Key findings
- 01 A proprietary ingredient blend, 'Wildplum Harvest™ AF' (containing Pleiogynium Timoriense Fruit Extract among other native Australian plums), is utilized at 1-2% in products formulated for mature skin. These products aim to provide hydration, nourishment, and rejuvenation, specifically targeting anti-aging and anti-wrinkle benefits.
- 02 An ethanolic extract demonstrated significant in vitro antioxidant activity, exhibiting an IC50 of 21.9 µg/mL for DPPH radical scavenging.
- 03 An ethanolic extract also showed moderate in vitro antioxidant activity through superoxide anion scavenging, with an IC50 of 123.5 µg/mL.
