Is Leuconostoc (Radish Root) Ferment Filtrate a Good Ingredient?

Rated Fair because it offers gentle antimicrobial support for preservation, but efficacy varies with pH and formula, and strong skin benefits are unproven. Some users may also experience irritation or sensitization, and it can be insufficient on its own in challenging systems, which keeps the rating in the middle.
