Science
Mechanism of Action
This ingredient functions as a robust antioxidant by utilizing its high concentration of Vitamin C, phenolic compounds, flavonoids, and anthocyanins to scavenge free radicals, thereby minimizing oxidative damage and visible signs of skin aging. It actively promotes collagen synthesis, a crucial process for maintaining skin elasticity and facilitating wound repair. Furthermore, Myrciaria dubia Fruit Juice exhibits significant anti-inflammatory properties by modulating key signaling pathways, including NF-κB/AP-1, MAPK, and NFAT, leading to a downregulation of pro-inflammatory cytokines and chemokines. It also activates nuclear factor E2-related factor 2 (Nrf2), enhancing the expression of antioxidant defense enzymes such as NAD(P)H:quinone oxidoreductase1 (NQO1) for superior keratinocyte protection. Additionally, it offers moisturizing benefits, helping to lock in hydration and improve skin elasticity, contributing to overall skin regeneration, radiance, and reduced signs of fatigue.

Stability
Due to its high Vitamin C content, approximately 26% of which can degrade during processing and storage, formulations should prioritize stability. Products containing this ingredient should be packaged in airless or highly air-restrictive containers, avoiding traditional jars or clear packaging. Its bioactive compounds are susceptible to degradation from high temperatures, light exposure, pH fluctuations, oxidative stress, and enzymatic activity. Encapsulation is a strategic approach to protect these compounds and enhance overall stability. For optimal preservation of key components like ascorbic acid, an acidic pH environment between 2.0 and 2.8 is indicated for good retention.
