Science
Mechanism of Action
This extract exerts its dermatological benefits through diverse mechanisms. It provides antioxidative protection by reducing radical levels and promoting cellular defense pathways (KEAP1, HO-1, p85/PI3K, AKT). For anti-aging, it modulates tissue remodeling factors like elastase, type 1 collagen, and MMP-1/-9, concurrently stimulating keratinocyte proliferation. Hydration is improved by inducing natural moisturizing factors such as filaggrin and hyaluronic acid synthase. Furthermore, it inhibits melanin synthesis and secretion by suppressing tyrosinase activity for brightening. For wound healing, it accelerates the process by increasing epithelialization, neovascularization, fibroblast proliferation, and collagen production, simultaneously suppressing inflammation. Its anti-inflammatory effects are attributed to phenolic compounds and cucurbitane triterpenoids, which reduce cytokine and MMP-9 levels. Additionally, it exhibits antibacterial activity against *P. acnes*, *E. coli*, *S. aureus*, and *S. epidermidis*, and shows anti-psoriatic effects by promoting epidermal differentiation.
Research
Clinical Evidence
High confidenceEfficacy has been demonstrated across a range of concentrations; 1% acetonic extract showed significant wound healing, 4.00% ethanol extract was successfully formulated into stable skincare creams, and a 13.36% ethanolic extract demonstrated substantial anti-psoriatic activity. The optimal percentage depends on the specific targeted benefit.
Key findings
- 01 A 1% Momordica charantia acetonic extract in a cream formulation significantly promoted wound healing in mice, with histopathological analysis revealing abundant fibroblasts, collagen, and elastic fibers.
- 02 An ethanolic extract of Momordica charantia leaves (13.36% yield) showed significant anti-psoriatic activity (63.94% overall) in a mouse tail model, comparable to 0.1% tazarotene gel.
- 03 Skincare creams containing 4.00% Momordica charantia leaves ethanol extract exhibited good stability for 3 months at both room and 60°C temperatures, maintaining a pH range of 6.37-6.67.
- 04 Anti-aging serums formulated with Momordica charantia extract demonstrated promising results in reducing wrinkles, improving skin elasticity, and enhancing moisturizing and brightening properties, without causing irritation.
- 05 Topical application of formulated leaf extracts in aqueous solution, pads, or lotion (pH 4-5) led to significant improvement in various grades of acne and furuncle within five days.
Transparency
Dusting Analysis
Clinical studies demonstrate Momordica Charantia Leaf Extract's efficacy starting from 1% for targeted benefits like wound healing, with other successful formulations utilizing 4% or higher concentrations. Therefore, concentrations significantly below 0.5% are unlikely to provide the researched benefits and could be considered a dusting quantity.
The Formula
Formulation
Stability
Natural extracts, including Momordica charantia, can benefit from stabilizers like Vitamin E oil and glycerin to enhance stability. Starch-based formulations can provide controlled release of active components. Ethanol extracts at 4.00% have shown stability in cream bases for up to 3 months at temperatures ranging from room temperature to 60°C, maintaining a pH between 6.37-6.67. For acne treatments, adjusting the pH to 4-5 using acids can enhance antimicrobial activity and prevent the precipitation of tannic acid, which could potentially block pores.
Conflicts
- Components that may cause precipitation of tannic acid or lead to the blockage of the pilosebaceous layer if pH is not adequately maintained, particularly in acne formulations.
Safety
Safety Profile
Specific safety assessments by official regulatory bodies such as CIR, SCCS, or FDA for cosmetic application are not yet available. However, existing studies indicate a favorable safety profile. Topical applications have reported a 'lack of any side effects,' and an anti-aging serum containing the extract showed 'no signs of skin irritation, redness, or allergic reactions' in irritancy tests. Animal toxicological evaluations (up to 2000 mg/kg acute oral and 400 mg/kg for 28 days repeated oral administration) demonstrated no clinical or behavioral signs of toxicity, nor hepatotoxic or nephrotoxic effects.
