Our take
Is Morus Nigra (Mulberry) Root Extract a Good Ingredient?
There are plausible tyrosinase-inhibiting constituents, but only modest human support, which is why it rates Fair. Potential for irritation or allergic response exists, and extract quality can vary between suppliers.
What it does
Skin Benefits
Improves the look of blotchy pigmentation and lends light antioxidant support, though controlled human data are modest, so expectations should remain conservative.
