Our take
Is Hydrolyzed Soybean Fiber a Good Ingredient?
Rated Good because it acts as a gentle film former that helps retain moisture and improve skin feel, with a low likelihood of irritation. The benefits are mostly sensory and hydration support rather than clinically proven corrective effects, which is enough for Good but not higher.
