What it is
This ingredient is the extract obtained after fermenting European mistletoe (Viscum album) with Saccharomyces yeast. Fermentation breaks the plant substrate down into smaller components such as amino acids, peptides, and sugars that are used in cosmetics to hydrate and condition the skin. It is typically added at low levels as a supporting conditioning agent rather than a primary functional ingredient.
Safety & warnings
Botanical ferment extracts of this type are generally well tolerated at cosmetic use levels. Because mistletoe is a botanical source, sensitive individuals can occasionally react to plant-derived byproducts, so a patch test is reasonable for reactive skin. It is not considered a notable comedogen at typical use levels.
Origin & sourcing
Biotechnological. It is produced by fermenting European mistletoe (Viscum album) with Saccharomyces yeast and then extracting the fermented material.
