What Is Lactobacillus/Tomato Fruit Ferment Extract?
Lactobacillus/Tomato Fruit Ferment Extract is produced by fermenting tomato fruit using Lactobacillus bacteria. During fermentation, the bacteria break down tomato compounds and produce metabolites — organic molecules that can benefit the skin. This process creates a concentrate that combines both the conditioning properties of tomato and the bioactive compounds generated through fermentation.
In skincare formulations, this ingredient functions primarily as a skin and hair conditioning agent, helping to improve texture and maintain hydration at the skin surface.
How It Works
The Lactobacillus fermentation process creates bioactive metabolites from tomato fruit. These compounds can form a conditioning film on the skin surface, helping to reduce transepidermal water loss and improve hydration. Additionally, the antioxidant compounds present in tomato (particularly lycopene) may help neutralise free radicals, though their bioavailability in fermented form requires further investigation.
Clinical Evidence & References
Specific clinical studies on this exact ingredient combination are limited. However, tomato and its active compounds have been studied for antioxidant and photoprotective properties in skincare. Fermentation as a process is known to alter the bioavailability of plant compounds, but research on how this specifically enhances efficacy in topical application is ongoing.
While this ingredient is well-established in cosmetic formulations, robust clinical data comparing it to other conditioning agents remains modest. It appears to be well-tolerated as a supporting ingredient rather than a primary active.
How to Use
This ingredient is typically found in leave-on skincare products such as serums, moisturisers, and essences. Since it functions as a conditioning agent, it works well alongside other actives and does not require specific timing. Apply to clean skin as part of your regular routine.
