What Is Lactobacillus/Rice Ferment?
Lactobacillus/Rice Ferment is created by fermenting rice with Lactobacillus bacteria. During fermentation, the bacteria break down rice proteins into smaller peptides and amino acids, creating bioactive compounds that wouldn't be present in unfermented rice.
In skincare formulations, this ingredient functions as both a skin and hair conditioner. The fermentation process is thought to enhance the biological activity of rice compounds, making them more accessible to skin.
Benefits for Your Skin
How It Works
Fermented rice peptides appear to work through multiple pathways. Research indicates they may activate antioxidant enzymes within skin cells via the KEAP1-NRF2 pathway, a key cellular defence system against oxidative damage. They may also modulate inflammatory signalling pathways (MAPK and NF-κB), potentially reducing skin inflammation.
The peptides and amino acids also have humectant properties, drawing moisture into the skin and supporting the natural barrier function.
Clinical Evidence & References
Laboratory and animal studies suggest fermented rice peptides have antioxidant and anti-inflammatory properties. Research using fermented rice with Lactobacillus shows promise in reducing inflammation in atopic dermatitis models, particularly when combined with other botanical ingredients.
However, human clinical trial data specifically for this ingredient in skincare is limited. Most evidence comes from in vitro studies and animal models, so more research in human volunteers would strengthen confidence in its real-world skin benefits.
