What Is Lactobacillus/Pumpkin Ferment Extract?
Lactobacillus/Pumpkin Ferment Extract is created by fermenting pumpkin using lactic acid bacteria strains. Fermentation breaks down the plant material and generates bioactive compounds, including organic acids and antioxidants. The result is a concentrated extract that functions as a skin conditioner.
This ingredient combines two elements: the beneficial microbes (Lactobacillus) and the nutrient-rich pumpkin base. The fermentation process enhances the bioavailability of compounds already present in pumpkin, such as carotenoids and polyphenols, potentially making them more useful to skin.
How It Works
The fermentation process generates compounds that can neutralise free radicals and reduce reactive oxygen species (ROS) in skin cells. This antioxidant action may protect skin from environmental stressors and support overall skin resilience.
Additionally, certain compounds in the ferment may inhibit enzymes that break down collagen and elastin—key structural proteins in skin. By slowing this breakdown, the ingredient may help support skin firmness and elasticity over time.
Clinical Evidence & References
Laboratory studies show that fermented pumpkin extracts demonstrate antioxidant capacity and can reduce ROS levels in cultured skin cells (keratinocytes and fibroblasts). The same studies found evidence of anti-inflammatory and enzyme-inhibiting effects, suggesting potential anti-aging benefits.
However, these are early-stage in vitro findings. Human clinical trials are limited, so claims about real-world effects on ageing, inflammation, or skin firmness should be considered preliminary. More research is needed to confirm efficacy in actual skincare formulations and on living skin.
How to Use
This ingredient is typically used in toners, essences, or serums at modest concentrations. Apply to clean skin before moisturiser. Since fermented extracts are generally gentle, they can be used daily, though as with any new ingredient, patch testing is sensible if you have reactive skin.
