Mechanism of Action
This extract exerts its multifaceted effects through a rich profile of bioactive compounds, including potent carotenoids such as lycopene and beta-carotene, alongside vitamins E (alpha-tocopherol) and C, polyphenols, and flavonoids. Its primary mechanism involves robust free-radical scavenging, which safeguards cellular membranes from damage and counteracts oxidative stress, thereby improving overall skin health and elasticity. The extract promotes enhanced skin hydration by increasing cutaneous water content and reducing transepidermal water loss. For anti-aging, it demonstrably improves skin smoothness and elasticity, while also reducing the visible appearance of wrinkles. Furthermore, it contributes to skin brightening by significantly inhibiting tyrosinase activity (up to 62.83% ± 1.99%) and suppressing p-PKC signaling, leading to decreased melanin production. It also possesses anti-inflammatory potential, aiding in the alleviation of oxidative stress and skin damage induced by environmental pollutants.

Clinical Evidence

Key findings
- 01 An anti-wrinkle cream formulated with Momordica Cochinchinensis fruit extract significantly improved cutaneous hydration and smoothness, and visibly reduced skin wrinkles over a 56-day period in a study involving 22 healthy volunteers aged 45-60.
- 02 Topical application of a hydrogel containing Momordica Cochinchinensis fruit extract significantly moisturized the skin and enhanced its elasticity over 30 days in 14 healthy female volunteers.
- 03 In vitro studies showed Momordica Cochinchinensis extracts (pulp and aril-derived) and oil inhibited tyrosinase activity in a dose-dependent manner (11.9% to 50.1% inhibition) at concentrations of 500-1000 µg/mL, suggesting anti-melanogenesis effects.

The Formula
Formulation
Stability
The carotenoids (lycopene, beta-carotene) present in the extract are vulnerable to degradation by environmental factors such as light, oxygen, and temperature fluctuations. Optimal drying methods can enhance its antioxidant properties. For stability, it should be stored in a cool, dry place in tightly sealed containers, protected from heat and light, to maintain efficacy for a shelf life of 6 months or longer.
Conflicts
- Its inherent low water-solubility makes it incompatible with purely water-based formulations (e.g., hydrogels) without the strategic use of solubilizers (e.g., Labrafac™ PG, Tween 60).
Safety
Safety Profile
Momordica Cochinchinensis fruit (Gac fruit) is considered non-toxic for cosmetic applications. Acute skin tolerance tests, specifically human patch tests on healthy adult subjects, demonstrated non-irritating properties with a Mean Irritation Index of 0.00.
