Science

Mechanism of Action

This extract functions as a powerful antioxidant by neutralizing free radicals, thereby safeguarding the skin from environmental stressors and mitigating signs of premature aging, such as fine lines and sun damage. Its rich composition of vitamins (A, C, E), minerals (potassium, magnesium), and antioxidants (flavonoids, phenolic acids, ellagitannins, beta-carotene, quercetin) underpins its multifaceted action. It provides significant hydrating and humectant benefits, optimizing the skin's moisture content and strengthening its natural barrier for a soft, supple feel. The natural Vitamin C content actively stimulates collagen synthesis, enhancing skin elasticity and firmness. Furthermore, it possesses anti-inflammatory properties to calm redness and irritation, alongside demonstrated antimicrobial efficacy against specific skin pathogens like Staphylococcus aureus.

Stability

Key active polyphenols, such as ellagitannins, maintain stability in acidic environments (pH 3.7-4.0). However, they are susceptible to rapid degradation in neutral or mildly basic conditions when exposed to elevated temperatures (60–80 °C). Microencapsulation can be a beneficial strategy to preserve polyphenol integrity during storage.
