Saccharomyces/Prunus Mume Extract Ferment Filtrate

This ingredient is a fermented extract derived from Japanese apricot (Prunus mume) that has been processed using Saccharomyces yeast. Fermentation breaks down the plant material into smaller molecular components, which may enhance absorption and alter the bioavailability of beneficial compounds.In skincare formulations, it functions primarily as a humectant — a substance that attracts and binds water to the skin's outer layers, helping to improve hydration and surface moisture content.

Humectant ingredients work by hygroscopic action — they attract water molecules from the surrounding environment and the deeper layers of skin, then hold them within the outer skin layer. This increases hydration at the surface without adding oil.The fermentation process in this ingredient may also produce organic acids and other bioactive compounds that support skin condition, though research specific to this particular ferment is limited.

This ingredient is typically found in serums, essences, and hydrating toners where it can work synergistically with other humectants and occlusive agents. For best results, apply to damp skin to trap additional moisture, then follow with a suitable moisturiser or facial oil to prevent transepidermal water loss.

Generally well-tolerated. Those with sensitivities to fermented ingredients or yeast should patch test first.
