Science
Mechanism of Action
This extract functions as a potent antioxidant, actively neutralizing free radicals to mitigate oxidative stress. Its Vitamin C content supports collagen production, vital for skin elasticity, while polyphenols like corilagin may help reduce cellulite appearance by inhibiting the PAI-1 pathway. The extract exhibits anti-inflammatory properties through reducing nitric oxide (NO) and TNF-alpha, and potentially blocking COX-2, further bolstered by increased activities of antioxidant enzymes such as catalase, superoxide dismutase, and glutathione peroxidase. It contributes to anti-aging by reducing cellular glycation and inhibiting collagenase activity, thereby preserving collagen integrity. Additionally, it has demonstrated potential skin-whitening effects by decreasing melanin production.

Key findings
- 01 An ethyl acetate extract from black Dimocarpus longan seed (a related species), at 0.5% concentration within a lamellar liquid crystal formulation, showed potent inhibition of MMP-1 (matrix metalloproteinase-1) and hyaluronidase, demonstrating significant anti-aging activities with no observed irritation.
- 02 An in vitro evaluation of a whole Dimocarpus longan fruit concentrate (concentration not specified for topical use) demonstrated high antioxidant potential, a significant reduction in collagenase activity, dose-dependent skin whitening effects, and skin-soothing effects on 2D-HaCaT and 3D-RHE models.

Stability
The ingredient maintains chemical stability under standard ambient conditions (room temperature) and should be stored tightly closed. When dissolved in water, its pH is typically neutral to slightly acidic. A related longan seed extract formulation demonstrated good stability at pH 5.5.
Safety
Safety Profile
Euphorbia Longan Fruit Extract has not been specifically reviewed by the Cosmetic Ingredient Review (CIR) Expert Panel. The EWG Skin Deep® database rates it with 'LOW' concerns for cancer, allergies & immunotoxicity, and developmental & reproductive toxicity, although noting 'LIMITED-FAIR' data availability. A related Dimocarpus longan seed extract showed no irritation in the Hen's Egg Chorioallantoic Membrane (HET-CAM) test, supporting its safety for topical application.
