Science
Mechanism of Action
This oil operates through multiple pathways to benefit the skin: its high content of omega 9 fatty acids strengthens the hydrolipidic barrier, enhancing moisture retention and tonicity. A rich profile of omega 6 fatty acids and flavonoids delivers potent antioxidant activity, neutralizing free radicals, preventing premature aging, and promoting skin tissue regeneration. Its antimicrobial and antiseptic characteristics, partly due to compounds like karanjin and pongamol, protect against harmful bacteria, reduce inflammation in conditions such as psoriasis and dermatitis, and support wound healing. Karanjin and pongamol also contribute to its ability to absorb and filter UVA/UVB rays, while its emollient nature effectively softens the skin's surface.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has not issued a specific safety assessment for Pongamia Glabra Seed Oil, noting 'Insufficient Data' for the broader category of Plant-Derived Edible Oils. The FDA also ceased evaluation of a GRAS notice for 'Pongamia bean oil' as a food ingredient. Crucially, unrefined Karanja oil contains toxic flavonoids (karanjin and pongamol), which are safely removed during the refining process, making the refined oil suitable for cosmetic use. SkinSAFE categorizes it as 'Irritant Free', and INCIDecoder assesses its irritancy as low.
