Niacinamide is stable enough to tolerate a dropper, which is why it is the format most of the library is built around. The decision is really about viscosity: a watery gel-serum wants a glass dropper, a milky or silky serum reads better in a pump, and either works in airless if the brand position is clinical.
Niacinamide Serum is one of 2,098 formulas in the library that fall into this form. Across the whole library, 54% of them are built for a glass bottles — that is the format the form itself is designed around, not a preference we hold. If the formula you pick is lighter or heavier than the typical niacinamide serum, the recommendation moves with the viscosity, which is why every formula page in the library shows its own pack pairing rather than a category rule.
Typical textures in this group: Slippery essence, Watery gel-serum, Light milky serum, Ample gel.













The one real constraint is not the active but the texture. A milky serum in a dropper separates in the pipette and looks spoiled; keep the low-viscosity formats in droppers and the emulsified ones in pumps.
