Lactobacillus/Evening Primrose Seed Ferment Filtrate

Lactobacillus/Evening Primrose Seed Ferment Filtrate is a liquid extract made by fermenting evening primrose seeds using beneficial Lactobacillus bacteria. The fermentation process breaks down plant compounds into smaller molecules that the skin can more readily absorb, whilst the filtrate removes solid plant matter, leaving a concentrated liquid ingredient.Evening primrose is traditionally valued for its fatty acid profile, particularly linoleic acid and gamma-linolenic acid (GLA). When fermented, these compounds may become more bioavailable. The Lactobacillus component adds probiotic-deri…

The fermentation process converts evening primrose seed compounds into forms that penetrate the skin more effectively. Lactobacillus species produce metabolites — including organic acids and antimicrobial peptides — that can influence skin pH and microbial balance. These compounds work together to condition the skin surface and support the barrier's ability to retain moisture.The ingredient functions primarily as a skin conditioner rather than an active treatment, meaning it helps optimise skin texture and comfort rather than target specific skin concerns directly.

This ingredient is typically used as a supporting player in serums, essences, and moisturisers rather than as a standalone treatment. It pairs well with other hydrating and barrier-supporting ingredients. Apply to clean skin as part of your regular routine; there is no evidence that it requires special timing or frequency beyond standard skincare practice.

Generally well-tolerated by most skin types. Those with sensitivity to fermented ingredients or evening primrose should patch-test first, as fermentation may alter allergenicity.
