Lactobacillus … Ferment Filtrate

This ingredient is a fermented filtrate combining three components: Lactobacillus (a probiotic bacteria), honey, and Matricaria chamomilla (German chamomile) flowers. The fermentation process breaks down the plant material and honey, creating a liquid extract rich in beneficial compounds including amino acids, organic acids, and polysaccharides.In skincare formulations, it functions as both a humectant—drawing moisture into the skin—and a skin conditioning agent that helps improve the overall feel and appearance of the skin.

The fermentation process creates a complex mixture of compounds that work on multiple levels. Lactobacillus and its metabolites may help maintain a balanced skin microbiome, whilst the honey and chamomile components provide hydration and soothing benefits through their polysaccharides and flavonoids respectively.When applied topically, the humectant molecules draw water into the skin's outer layers, whilst the conditioning agents help smooth the skin surface and reduce transepidermal water loss.

This ingredient is typically found in serums, essences, and hydrating toners where it can be applied to clean skin before heavier creams or oils. Since it's a fermented extract, it works well layered with other hydrating or treatment products. Use twice daily or as tolerated by your skin.

Generally well-tolerated across most skin types. Those with sensitivity to fermented ingredients, honey, or chamomilla should patch test first, as fermented products can occasionally trigger sensitivity in reactive skin.
