Is Copper Gluconate a Good Ingredient?
It can act as a trace mineral conditioner, but clinical support for visible benefits in everyday use is limited. Some individuals may experience mild irritation or sensitivity at higher concentrations or in leave‑on formats. That combination of thin evidence and irritation potential is why it rates Fair, not Good.
