Science
Mechanism of Action
This extract operates through a multi-pathway approach: it utilizes tartaric and malic acids for non-mechanical desquamation, while its high concentration of naringenin and quercetin neutralizes oxidative stress. Furthermore, it stimulates endogenous hyaluronic acid secretion to maintain moisture levels and activates luciferase pathways to downregulate inflammatory markers by up to 40%.

Key findings
- 01 Demonstrated 18.0% to 28.4% improvement in skin hydration metrics over a 21-day period.
- 02 Achieved measurable melanin reduction between -3.36 and -5.64 units within three weeks of consistent application.
- 03 Observed broad-spectrum bactericidal activity at concentrations as low as 0.1%.
- 04 DPPH radical scavenging tests show an antioxidant capacity between 70% and 90%.

Dusting Analysis
Often included at trace amounts (<0.1%) solely for fragrance or 'natural' marketing claims. Clinical benefits for skin texture and hydration require concentrations closer to 1.0%.
The Formula
Formulation
Stability
The extract is inherently acidic (pH 2.0-3.5) and remains stable at room temperature. It may darken over time due to natural vitamin C content.
Synergies
- Sunscreen agents
- Glycerin
- Hyaluronic Acid
Conflicts
- Carbomer (may cause viscosity loss)
- Anionic emulsifiers
- Strong surfactants
- Oxidizing agents that may degrade limonene into sensitizing hydroperoxides
Safety
Safety Profile
Contains furanocoumarins and limonene which may induce photosensitivity. We recommend evening application or rigorous broad-spectrum SPF 30+ during daylight hours. Potential irritant for citrus-allergic individuals.
