SACCHAROMYCES/GRAPE LEES FERMENT FILTRATE

Fermented Grape Lees Extract

Safety grade: A

This ingredient is made by fermenting grape byproducts (the solids left over from winemaking) with a beneficial yeast called saccharomyces. The resulting liquid is filtered and used in skincare products.

It acts as a humectant, meaning it draws moisture from the air and deeper skin layers to the surface, helping to keep skin hydrated and plump.

Graded using: COSING.
