BIOME Oléoactif®


[Skin-Microbiome] care

BIOME Oléoactif® is the first ingredient obtained by capturing rare lipids from a wild extremophilic microorganism, then offering them to the skin and its microbiome. At the crossroads of bacterial and vegetable worlds, BIOME Oléoactif® both reinforces the integrity of the epidermal barrier and preserves the microbiota of healthy skin to prevent cutaneous discomfort and disease. 

This active ingredient is produced by fermentation from an extremophilic microorganism from the DEINOVE collection and extracted by HALLSTAR BEAUTY's patented Oleo-eco-extraction process.

BIOME Oléoactif® is a COSMOS-certified natural beauty enhancer complex, totally safe with proven efficacy at low dose.


Strengthening of epidermal defense mechanisms and physical cutaneous barrier 

The skin is constantly exposed to extrinsic and intrinsic factors that can impair the lipid barrier and weaken cutaneous immune and antioxidant defenses. In these conditions, cutaneous water loss increases while the skin is not protected against oxidative stress and pathogens. BIOME Oléoactif® is effective to boost gene expressions involved in epidermal barrier function.


Improving skin health and beauty by maintaining the balance of the skin microbiome

It is increasingly clear that the cutaneous microbiota makes important contributions to normal skin immune development and function. Extrinsic and intrinsic factors may influence skin disruptions by inducing dysbiosis linked to the decrease of the microbial diversity notably characterized by a loss of protective bacteria and an overgrowth of pathogenic or opportunistic microorganisms. To prevent imbalanced skin conditions, experts recommend using cosmetics preserving skin microbiota ecosystem. 

BIOME Oléoactif® preserves the bacterial diversity and the microbiota global composition of healthy skin. In addition, BIOME Oléoactif® presents a prebiotic effect by selectively modulating the growth of certain bacterial species present on the skin, for a better skin protection against pathogens and over-expressed inflammation, and a better skin oxygenation.


From volcanic sources to skin  

Bacteria are the ancestral origin of life endowed with unique adaptation systems to the environment. 

To create BIOME Oléoactif®, DEINOVE isolated a rare bacterial strain harvested in a volcanic underground thermal water source. After fermentation under controlled conditions, the biomass is extracted by Hallstar Beauty’s patented green process to provide its best benefits to the [skin-microbiome] ecosystem. 


Post-prebiotic concept with a unique multifunctional lipid composition 

BIOME Oléoactif® is the first ingredient that combines a postbiotic origin with a prebiotic effect under 100% oil-based composition. Indeed, Hallstar Beauty succeeded to reach the microorganism’s precious lipid part by extracting a rare ramified fatty acid, iso C15, then providing it as a support to skin microbiota for health benefits. This extracted fatty acid acts in synergy with vegetable lipids from jojoba liquid wax and oat oil, conferring innovative properties to BIOME Oléoactif®.
