Is Quillaja Saponaria Bark Extract a Good Ingredient?

Fair, because although it's rich in saponins that act as effective natural surfactants for cleansing and foam, that same potency can strip lipids and irritate skin. Tolerability varies with concentration and formulation, which keeps it from a higher rating.
