Put the denominators next to each other
The number 31.3% on the APLB complex includes a large contribution from centella. Its niacinamide component is 2%. Someone trying to reorder a ten-percent niacinamide serum should not put the two large front numbers in the same column. The Ordinary’s ten percent refers to niacinamide itself. This exercise settles identity, not which concentration will feel best.
| What changes | APLB Glutathione Niacinamide Ampoule Serum | The Ordinary Niacinamide 10% + Zinc 1% |
|---|---|---|
| Niacinamide | 2% | 10% |
| Distinctive accompanying declaration | 0.1% glutathione within the named blend | 1% zinc on the front label |
The 40 mL APLB ampoule declares 2% niacinamide and 0.1% glutathione. The Ordinary names 10% niacinamide and 1% zinc in its formula.
Fit the dropper into an existing routine
A higher percentage does not tell you how a serum will dry under a moisturizer or whether it becomes sticky at the amount you use. APLB customers linked from the serum listing describe both easy spreading and a sticky finish. If consistency matters more than maximizing a percentage, compare a small amount with the moisturizer you already own before changing several products at once.
What customers reported
The Ampoule Serum spread easily for one customer, who reported little visible change after several months.

Our recommendation
The Ordinary is the clear label match for a shopper seeking its 10% niacinamide and zinc combination. APLB suits a shopper seeking the specifically declared 2% formula with centella and glutathione.
