Science
Mechanism of Action
This extract operates through a multifaceted mechanism, primarily leveraging its rich profile of phenolic compounds, flavonoids, chalcones (such as butein and isoliquiritigenin), and flavanones like naringenin. These phytochemicals impart potent antioxidant capabilities, neutralizing free radicals and mitigating oxidative stress within skin cells. Furthermore, the extract demonstrates anti-inflammatory action by reducing edema, suggesting modulation of inflammatory pathways. Beyond these, it may also contribute to skin regeneration and collagen deposition, potentially aiding in wound healing, and has shown antimicrobial activity against various pathogens.

Key findings
- 01 An aqueous extract, administered orally at 50-800 mg/kg, significantly reduced acute inflammation (hind paw edema) in rats in a dose-dependent manner, confirming anti-inflammatory effects.
- 02 Extracts exhibit significant antioxidant properties, attributed to the presence of phenolic compounds, flavonoids, chalcones, and naringenin.
- 03 A water extract of the stem-bark promoted wound healing by improving epithelialization time and tensile strength in rat excision and incision wounds. Histological analysis revealed enhanced collagen synthesis and reduced inflammatory cells.

Dusting Analysis
No data available to suggest this ingredient is commonly 'dusted' or used at concentrations beyond its demonstrated efficacy for skin benefits.
The Formula
Formulation
Stability
The fruit is amenable to both aqueous and ethanolic extraction methods. The intrinsic pH of the fruit ranges from 4.8 to 6.96, while infusions can present a pH between 3.35 and 4.15. No specific optimal pH range for stability in finished cosmetic formulations has been documented.
Safety
Safety Profile
No dedicated safety assessment for cosmetic use by CIR, SCCS, or FDA was identified. Acute oral toxicity studies in rats indicate low toxicity, with LD50 values exceeding 1000 mg/kg and >5000 mg/kg for various extracts. However, high oral doses (above 400-1000 mg/kg) in rats may impact renal and liver function. An in vitro study showed weak mutagenic activity for a methanol extract of the fruit. The raw fruit naturally contains oxalates, tannins, and hydrocyanic acid, which are generally not present in purified extracts for cosmetic use but warrant consideration for raw material sourcing.

Verdict
While exhibiting promising antioxidant and anti-inflammatory benefits in preliminary studies, the lack of specific topical concentration data and formal cosmetic safety review necessitates further research for precise application in advanced skincare formulations.
