Science
Mechanism of Action
This extract functions via a diverse array of bioactive components, including sterols, triterpenoids, and flavonoids. It exerts antioxidant effects by reducing radical levels in keratinocytes and providing cytoprotection. Anti-aging properties stem from its ability to regulate elastase and matrix metalloproteinases (MMPs), enhancing collagen synthesis and promoting HaCaT cell proliferation. It supports skin barrier function and hydration by inducing natural moisturizing factors like filaggrin and hyaluronic acid synthases. Furthermore, it inhibits melanin synthesis through tyrosinase suppression and reduces Propionibacterium acnes-induced inflammation and MMP-9 levels, offering antimicrobial and anti-acne benefits. Its astringent nature also contributes to pore tightening and improved skin elasticity.

Clinical Evidence
Medium confidence1%
Key findings
- 01 A 1% cream formulation demonstrated significant efficacy in accelerating wound healing in mice, notably by increasing epithelialization, neovascularization, and fibroblast proliferation while effectively suppressing inflammation.
- 02 Recommended cosmetic use levels range from 1% to 3%, with concentrations near 3% capable of imparting a noticeable skin tightening sensation due to its astringent properties.
- 03 An ethanol extract at 4% concentration was successfully incorporated into skincare creams, maintaining stability for at least 3 months when stored at both room temperature and 60°C.

Dusting Analysis
Momordica Charantia Extract exhibits documented efficacy at concentrations ranging from 1% for wound healing to 3% for a notable tightening effect. These specific active levels indicate that significant clinical benefits are unlikely to be observed at concentrations below approximately 0.1%.
The Formula
Formulation
Stability
The extract shows good stability in anti-aging serum formulations within a skin-friendly pH range. A 4% extract in a cream maintained stability for 3 months with a pH of 6.37-6.67. Optimal processing involves adjusting pH between 2.5 and 4, followed by neutralization to pH 7.0 for sustained stability. The inclusion of Vitamin E oil and glycerin can enhance stability, while starch-based systems may facilitate controlled release. Ethanol extracts generally demonstrate good stability.

Safety
Safety Profile
No specific CIR or SCCS safety assessment is available. However, studies indicate a low risk of irritation or sensitization in RHE test models and an anti-aging serum formulation. The estimated oral LD50 in rats (>2,000 mg/kg) suggests low systemic toxicity. High concentrations, particularly above 3%, may induce excessive astringency for certain skin types.
