PRUNUS DOMESTICA LEAF EXTRACT.

Valuable / ANTIOXIDANT

Prunus domestica Leaf Extract, derived from plum leaves, is a rich botanical source of phenolic compounds and flavonoids. It delivers comprehensive skin benefits, including potent antioxidant and anti-inflammatory actions, alongside significant tyrosinase inhibition, promoting an even, protected, and healthier complexion.

Summary

Moisturising Skin conditioning Smoothing Antioxidant Antimicrobial Skin protecting Anti-inflammatory Anti-tyrosinase

Science

Mechanism of Action

The efficacy of Prunus domestica Leaf Extract stems from its high concentration of phenolic and flavonoid compounds, such as rutin, condensed tannins, and chlorogenic acid. These components actively scavenge free radicals and chelate metals, effectively mitigating oxidative stress and environmental damage to the skin. The extract also modulates inflammatory mediators to alleviate irritation and redness and specifically inhibits tyrosinase, a key enzyme in melanin production, thus addressing hyperpigmentation. Additionally, it forms a protective film, enhancing skin barrier function and contributing to improved hydration, smoothness, and overall skin conditioning.

Stability

Prunus domestica leaf extracts are sensitive to thermal degradation, with optimal stability maintained at moderate temperatures around 40°C. Certain components, such as anthocyanins found in plum peel extract, demonstrate enhanced stability in acidic environments (pH < 3), and plum syrup (fruit extract) showed good phenolic content stability at pH 3.49.
