Perfluorodecalin
Perfluorodecalin is a lightweight, breathable liquid used in some high-end skincare and colour cosmetics. It is valued for its ability to carry and deliver oxygen to the skin’s surface, giving products a silky, elegant feel without greasiness.
How it works in skincare
In cosmetics and skincare, perfluorodecalin functions as an emollient and skin-conditioning agent. It is a perfluorocarbon that can dissolve and transport gases, particularly oxygen, which helps create a temporary oxygen-rich environment on the skin. This property is utilised in premium creams, serums and masks to improve the appearance of tired-looking skin and to enhance the overall sensory experience of the formula.
