Saccharomyces/Peppermint Leaf Ferment Filtrate

Saccharomyces/Peppermint Leaf Ferment Filtrate is a liquid extract created by fermenting peppermint leaves using Saccharomyces (a type of yeast). The fermentation process breaks down plant compounds into smaller molecules that can be more readily absorbed by the skin. The filtrate — the liquid portion after solids are removed — is then used in skincare formulations.In cosmetics, this ingredient functions primarily as a skin conditioner, working to improve the texture and feel of the skin surface. The combination of fermented botanicals may offer gentle benefits without the intensity of some…

Fermentation breaks down complex plant structures into smaller, more permeable molecules. This process can enhance the bioavailability of beneficial compounds from the peppermint leaf, allowing them to interact with the skin more effectively.As a skin conditioner, this ingredient likely works by forming a light conditioning layer on the skin surface, helping to improve hydration retention and overall skin feel. Peppermint itself has a long history in traditional skincare, and the fermentation process may preserve or concentrate some of these properties.

This ingredient is typically found in serums, essences, and hydrating products. It can be used daily as part of your routine, usually after cleansing and before heavier creams or treatments. Because it is a conditioning ingredient rather than an active treatment, it works well alongside other skincare steps and can be layered with complementary products.

This ingredient is generally well-tolerated in skincare products. Those with known sensitivity to peppermint or yeast-derived ingredients should patch test first, though sensitising reactions are uncommon at typical cosmetic concentrations.
