DEINOVE announced the upcoming official commercial launch (in April 2020) of the first cosmetic active ingredient resulting from its collaboration with Hallstar France, BIOME Oléoactif. BIOME Oléoactif® is the first oil-based active ingredient obtained by extracting rare branched fatty acids from a wild extremophile microorganism into a blend of jojoba liquid wax and oat oil. It contains unique and original fatty acids - specific to bacteria, totally absent from the vegetal world, supplemented by polar lipids, known for their moisturizing properties and recognized as being an effective active principle vehicle. BIOME Oléoactif® is a postbiotic extract with a prebiotic effect: it both balances the skin microbiota and maintains the integrity of the epidermal barrier. Besides its moisturizing, restructuring, soothing and emollient properties, BIOME Oléoactif® can be combined with all types of ingredients to create a holistic system that promotes healthy, youthful, beautiful skin. As the heaviest and most extensive organ of the human body (about 2 sq.m. and 4-10 kg), the skin naturally maintains its own 'micro-ecosystem', which is constantly evolving throughout life. The micro-organisms present on and in the skin, collectively called cutaneous microbiota, play a real protective role: anti-inflammatory, anti-infectious, antioxidant and repairing. It is considered an integral part of skin barrier that, combined with innate immunity, is essential for maintaining the skin health. An imbalance in the microbiota – which may be caused by such factors as diet, hormonal imbalance, lifestyle - can then lead to several skin disorders, such as dandruff, acne, psoriasis, or atopic dermatitis.
