Science
Mechanism of Action
This extract functions primarily through its rich antioxidant content, which effectively neutralizes skin-damaging free radicals, thereby mitigating oxidative stress that contributes to premature aging, pigmentation, and collagen degradation. Its natural anti-inflammatory capabilities reduce skin redness and irritation by modulating inflammatory pathways. Furthermore, the presence of flavonoids and saponins provides antibacterial efficacy, assisting in maintaining skin clarity and combating blemish-causing bacteria such as Staphylococcus aureus. Kigelia Africana Bark Extract also promotes cellular regeneration and stimulates collagen synthesis. It contains compounds that emulate estrogen, boosting skin metabolism, hyaluronic acid production, and overall protein synthesis, which collectively improve skin elasticity, firmness, and minimize the appearance of fine lines. Additionally, it reinforces the skin barrier and optimizes moisture balance, leading to improved hydration and smoother texture, while also reducing excessive melanin production to minimize hyperpigmentation.

Safety Profile
No specific CIR, SCCS, or FDA status for cosmetic use was found. While acute and subacute toxicity studies in Wistar rats showed an LD50 above 5000 mg/kg, indicating safety in animal models at tested doses (50 mg/kg bm, 200 mg/kg mc), this animal data does not directly translate to regulatory cosmetic safety assessment for humans. As with all natural extracts, individual allergic reactions, such as skin irritation or itching, may occur, and sensitivity testing is recommended, especially for sensitive skin.
