Science
Mechanism of Action
This ingredient exerts its benefits through a sophisticated interplay of bioactive compounds, including flavonoids, anthocyanins (such as nasunin), chlorogenic acid, and vitamins C and E. These components synergistically promote natural skin renewal and equilibrium. Its potent antioxidant capacity precisely targets and neutralizes free radicals, mitigating oxidative stress and protecting skin cells from damage. Notably, specific phenolamides, particularly N-trans-feruloylputrescine, scavenge reactive aldehydes like 2-nonenal by forming covalent adducts, thereby shielding keratinocytes from oxidative damage and apoptosis. Additionally, flavonoids and anthocyanins contribute significant anti-inflammatory actions, reducing redness and irritation. The extract also fortifies the skin's protective barrier, enhances hydration, and supports collagen production, leading to improved elasticity and a more radiant complexion.

Key findings
- 01 Eggplant fruit extract, at a concentration of 10 mg/mL, demonstrated remarkable 2-nonenal scavenging activity in vitro, removing approximately 80% of this aging-associated aldehyde. This suggests its role in mitigating body odor and protecting skin from aldehyde-induced damage.
- 02 Pre-treatment with eggplant fruit extract (10 µg/mL) protected human keratinocytes against 2-nonenal-induced cytotoxicity, resulting in an approximate 10-18% improvement in cell viability. Further, N-trans-feruloylputrescine, a key active compound, significantly improved keratinocyte viability by about 12% at 10 µM, increasing to 46% at 200 µM against 2-nonenal-induced damage.
- 03 At 2 mg/mL, eggplant fruit extract significantly inhibited lipid peroxidation of arachidonic acid, leading to a 74.16% increase in residual arachidonic acid compared to the oxidized control, underscoring its antioxidant capability.
- 04 Pre-treatment with eggplant fruit extract (10 µg/mL) effectively attenuated 2-nonenal-induced Reactive Oxygen Species (ROS) elevation in human keratinocytes by 13.58%.
Transparency
Dusting Analysis
Based on the available clinical data, Solanum Melongena Fruit Juice demonstrates measurable efficacy at concentrations as low as 10 µg/mL in in vitro and cell-based studies. This suggests that the ingredient is not commonly 'dusted' at sub-efficacious levels.

Safety
Safety Profile
Solanum Melongena Fruit Juice is generally recognized as a safe cosmetic ingredient by international regulatory authorities, including the European Cosmetics Regulation, with no known specific harmful side effects. In vitro studies show no significant cytotoxicity up to 10 µg/mL on human keratinocytes. However, as with any natural ingredient, individual skin tolerance can vary, and a patch test is advisable for sensitive skin or those with known allergies.
