Formula IngredientAntioxidantINCI: Terminalia Ferdinandiana Fruit Extract
Terminalia ferdinandiana fruit extract is derived from the Kakadu plum, a native Australian superfruit from the Combretaceae family and one of the world's richest natural sources of vitamin C (ascorbic acid). In skincare, it functions primarily as a potent antioxidant, neutralising free radicals that cause oxidative stress and premature ageing. Its high phenolic content — including ellagic acid, hydrolysable tannins, and ascorbic acid — also contributes to skin brightening and anti-inflammatory effects.

No significant irritancy has been documented for this botanical extract at cosmetic concentrations. It is not listed under EU CosIng Annex II (banned) or Annex III (restricted). Its vitamin C content (ascorbic acid) can occasionally cause mild transient stinging on sensitive skin, but the extract form is generally considered gentler than pure L-ascorbic acid. Patch testing is advised for reactive skin types.
Terminalia ferdinandiana fruit extract is not classified as a photosensitising ingredient. Unlike AHAs or retinoids, it does not increase UV sensitivity. As an antioxidant, it may actually provide some indirect photoprotective benefit by neutralising reactive oxygen species generated by UV exposure, though it does not replace SPF.
No reproductive or developmental safety concerns have been identified for this botanical extract. EWG rates it as safe. It is a natural plant extract with no known teratogenic compounds. Standard precaution of consulting a healthcare provider before changing skincare routine during pregnancy applies.
