Morus alba bark extract is a botanical extract obtained from the outer tissues of the white mulberry tree. Formulators use it in brightening-leaning products and antioxidant blends, though evidence for tone-evening effects in humans remains limited.
Not typically evaluated for comedogenicity — no standardized rating available.
Our take
Is Morus Alba Bark Extract a Good Ingredient?
It shows in-vitro tyrosinase inhibition, but human brightening evidence is limited and extract variability can reduce consistency, which is why it rates Fair. It may also cause irritation in sensitive skin, so the benefits may not outweigh the risks for everyone.
