Saccharomyces/Laminaria Saccharina Ferment

Saccharomyces/Laminaria Saccharina Ferment is a fermented ingredient derived from sugar kelp (Laminaria saccharina), a brown seaweed, processed using Saccharomyces yeast. Fermentation breaks down the seaweed's cellular structure, creating smaller molecular compounds that the skin can more readily absorb.In skincare, this ingredient functions primarily as a skin conditioner. It supplies the skin with nutrients and polysaccharides derived from the seaweed, helping to support moisture retention and the skin's natural hydration balance.

Fermentation breaks down the seaweed's complex polysaccharides and cellular walls into smaller, more bioavailable compounds. This process makes the nutrient content more accessible to the skin's outer layers.Once applied, the ingredient hydrates by forming a film on the skin surface and by drawing moisture into the stratum corneum (the outer layer). The polysaccharides also support the skin's natural conditioning mechanisms, helping it feel and appear more comfortable.

This ingredient is typically found in serums, essences, moisturisers and toners. It works well in layered skincare routines — apply to clean skin before heavier moisturisers. As a conditioning ingredient, it can be used daily without concern. Patch-test first if you have very reactive skin, though sensitisation is uncommon.

Generally well-tolerated across skin types. Those with iodine sensitivity or seaweed allergies should avoid this ingredient or patch-test carefully first.
