Science
Mechanism of Action
This extract exerts its dermatological effects through several key pathways. It precisely stimulates the synthesis of critical extracellular matrix proteins, including fibronectin (by 16%) and collagen (by 60%), while also boosting fibroblast contractility by 30%, thus bolstering skin structure and accelerating wound healing. The presence of natural alpha-hydroxy acids (AHAs) facilitates gentle exfoliation, promoting cellular turnover and contributing to a smoother skin texture. Hydration and barrier function are significantly improved by stimulating the expression of aquaporin 3 and filaggrin genes by 20% and 58% respectively. Rich in antioxidants like anthocyanins and flavonoids, it effectively scavenges free radicals and minimizes oxidative stress. Additionally, it possesses anti-inflammatory capabilities to soothe irritated skin and reduce redness, alongside properties that can inhibit melanin production to address hyperpigmentation.

Safety
Safety Profile
Generally considered safe for topical application within cosmetic products. Studies observed no significant cytotoxicity at concentrations up to 0.05% v/v (ethanolic extract) or 100 µg/mL (fatty acid-rich fraction). However, patch testing is prudent, especially for individuals with sensitive skin, to identify any potential allergic reactions. Data regarding topical use during pregnancy or breastfeeding is currently limited, and professional medical consultation is advised. Comprehensive oral, dermal, and inhalation toxicity data has not been fully determined across all sources.
