Comedogenic Rating

This ingredient is not typically evaluated for comedogenicity, and no standardized rating is available.

Safety

Is Lactococcus Ferment Lysate (Probiotic) a Good Ingredient?

Rated Good because lysates like this show emerging evidence for improving hydration and supporting barrier-related markers, with generally low irritation. The data in cosmetics is promising but not as extensive as for well-established humectants, which keeps it at Good rather than Great.
