Formula IngredientEmollientINCI: Simmondsia Chinensis Seed Oil
Simmondsia chinensis seed oil, commonly known as jojoba oil, is a liquid wax ester pressed from the seeds of the desert shrub Simmondsia chinensis. Unlike most plant oils, which are triglycerides, jojoba is a wax ester — making it chemically very similar to human sebum and exceptionally stable at high temperatures. It moisturises through a dual mechanism: forming a light semi-occlusive barrier on the skin surface while also absorbing into the upper skin layers.
