The molecule
The three pieces are meant to be apart. Zinc Gluconate is a salt, and its parts are held to each other by opposite charges rather than by a bond.
The Glow take
Can help, with honest expectations.
When your goal is calming breakouts and congestion, Zinc Gluconate can genuinely help, though the evidence is still thin, so keep expectations gentle. It tends to suit combination skin best.

Where it fits in your routine
Give it eight to twelve weeks, and possibly less: that is simply when it was measured.
What was measured, and in whom
Measured on: reduction in inflammatory acne lesions.
A double blind placebo controlled trial of oral zinc gluconate at 200 mg daily reported a significantly better inflammatory acne score than placebo, but the abstract gives no timepoint of any kind. A second double blind study in 67 patients supports the conventional three month regimen. Both are oral, so the onset of any topical effect is unknown.
