What Is Euglena Gracilis Extract?
Euglena Gracilis Extract is a skin care ingredient derived from Euglena gracilis, a single-celled freshwater alga that sits somewhere between plants and animals in the biological world. The tiny organism is naturally packed with proteins, vitamins, minerals and a unique beta-glucan called paramylon that helps it store energy. First explored in the food industry as a nutritious supplement, Euglena gracilis drew the attention of cosmetic chemists in the early 2000s when lab studies showed the extract could improve skin hydration and resilience.
To create the extract, Euglena gracilis is cultivated in closed stainless-steel tanks filled with purified water and a balanced nutrient mix. Once the culture reaches the right density the cells are harvested, the cell walls are gently broken, and the contents are mixed with water or a mild solvent to pull out the active compounds. The liquid is then filtered, concentrated and preserved to meet cosmetic safety standards.
Thanks to its light texture and versatile profile, Euglena Gracilis Extract appears in many topical products including daily moisturizers, anti aging creams, hydrating masks, revitalizing serums, eye gels and after-sun treatments.
