Science
Mechanism of Action
This extract employs a dual-action pathway: its high-molecular-weight mucilaginous polysaccharides create a breathable, bio-mimetic film on the stratum corneum to lock in moisture and mitigate transepidermal water loss (TEWL). Simultaneously, its concentrated phenolic acids and flavonoids neutralize reactive oxygen species (ROS) and inhibit matrix-degrading enzymes like elastase and collagenase, preserving the skin's structural integrity.

Key findings
- 01 In-vitro assessments show up to 95.49% DPPH radical scavenging activity at concentrations reaching 100 µg/mL.
- 02 Studies on related Cactaceae polysaccharides demonstrate significant barrier restoration and TEWL reduction at 1-2% inclusion levels.
- 03 Cell viability testing indicates protective anti-proliferative effects against oxidative stress-induced damage.

Dusting Analysis
Due to its exotic 'Queen of the Night' branding, this ingredient is frequently used at trace levels (<0.1%) for marketing purposes. To achieve the documented barrier-repair and humectant benefits, concentrations between 1% and 2% are required.
The Formula
Formulation
Stability
The extract is naturally acidic (pH 3.9–5.6). It is highly stable in aqueous formulas but sensitive to thermal degradation; avoid processing temperatures above 40°C to preserve antioxidant potency.
