Dr.Ceuracle VEGAN NIACIN & RICE AMPOULE

An ampoule should deliver at least one evidence-backed active, but Dr.Ceuracle Vegan Niacin & Rice Ampoule contains none that meet that bar — niacinamide is in the name yet not confirmed as a clinically supported ingredient in this formulation's assessed profile. Skip it and put your money toward an ampoule with verified actives.
