Lactobacillus/Olive Leaf Ferment Extract

Lactobacillus/Olive Leaf Ferment Extract is created by fermenting olive leaf using Lactobacillus bacteria. This process breaks down the plant material and allows the bacteria to produce beneficial compounds, resulting in an ingredient that combines probiotic activity with the polyphenols naturally present in olive leaf.In skincare formulations, this ingredient functions as a humectant and skin conditioner. It helps draw moisture into the skin and supports the skin's natural moisture retention, whilst the fermentation byproducts may contribute conditioning properties that help improve skin t…

The fermentation process converts olive leaf into a more bioavailable form. Lactobacillus bacteria produce metabolites and enzymes that break down plant cell walls, releasing compounds like polyphenols and carbohydrates that can support skin hydration and conditioning.As a humectant, the ingredient draws moisture into the stratum corneum (the skin's outer layer), helping to plump the skin and improve hydration. The conditioning agents then help seal this moisture, reducing transepidermal water loss.

This ingredient is typically used as a supporting ingredient rather than a standalone treatment. It appears in serums, essences, toners, and moisturisers at concentrations that contribute to overall hydration and conditioning. Use as directed by the specific product formulation, usually once or twice daily as part of your regular skincare routine. It pairs well with other hydrating and barrier-support ingredients.

Lactobacillus/Olive Leaf Ferment Extract is generally well-tolerated across skin types. Those with sensitivities to fermented ingredients or olive should patch-test first, though adverse reactions are uncommon.
