Summary

Hydration Barrier Support Exfoliation (Gentle) Antioxidant Anti-inflammatory Collagen Stimulator Fibronectin Synthesizer Wound Healing Anti-melanogenic Acne Control

Science

Mechanism of Action

This extract operates through multiple pathways to improve skin health. It stimulates the expression of key genes such as aquaporin 3 (by 20%) and filaggrin (by 58%) in human keratinocytes, thereby enhancing hydration and reinforcing the skin's natural barrier. Its content of natural alpha-hydroxy acids (AHAs) provides gentle exfoliation, encouraging healthy cell turnover. Rich in anthocyanins, flavonoids, mucilage, and organic acids, it delivers robust antioxidant protection against free radical damage. Furthermore, it exhibits anti-inflammatory properties, significantly boosts fibronectin synthesis by 16% and collagen synthesis by 60% in human fibroblasts, and accelerates wound healing. Preliminary data also suggests potential anti-melanogenic effects and assistance in controlling acne breakouts.
