Microalgae
Microalgae are tiny plant-like organisms from the sea and freshwater that are packed with vitamins, antioxidants and proteins. In beauty products they are used to hydrate, protect and revitalise skin and hair. You will often find them in modern serums, creams and masks as a sustainable, nutrient-rich ingredient.
How it works in skincare
In skincare and haircare formulations microalgae extracts deliver a concentrated blend of amino acids, polysaccharides and carotenoids that help strengthen the skin’s moisture barrier and shield against environmental stressors. Their natural ability to bind water makes them excellent humectants, while antioxidant compounds assist in maintaining a smoother, more radiant appearance. Because they are so lightweight, microalgae work beautifully in both lightweight serums and richer creams without feeling heavy on the skin.

Where it comes from
Microalgae are microscopic marine or freshwater organisms that grow naturally in oceans, lakes and rivers. They are sustainably cultivated in controlled environments rather than harvested from the wild.
