Our take
Is Milk Protein Extract a Good Ingredient?
Evidence for meaningful, reproducible skin effects is limited, and it mainly adds a soft, hydrated sensation, which is why it rates Fair. Being milk-derived, it also carries allergen potential for individuals sensitive to dairy proteins.
What it does

Safety
