Vegan Niacin & Rice Ampoule
Reviewed by SerumTruth Editorial · Updated July 2026
The niacinamide half of the name is real and properly dosed; the rice half is mostly branding, since the extract itself is a trailing ingredient rather than a headline percentage. Fairly priced for a nightly niacinamide ampoule with a pleasant, creamy finish, worth buying for the niacinamide and the retinoid-ester bonus, not for a rice-forward glow effect.

What’s inside
| Active | Disclosed | Dose |
|---|---|---|
| Niacinamide | 2% | Studied |
| Rice Extract (Rice Bran Water / Ferment) | n/a | Below 1% line |
A vegan, creamy ampoule built on a brand-stated 2% niacinamide for the appearance of a brighter, more even tone, with panthenol and sodium hyaluronate for hydration. Despite lending its name to the product, rice extract (Oryza Sativa Extract) sits well down the ingredient list, after texture and gelling agents, so it reads as a trailing addition rather than a dosed second active on the order of the rice-forward glow serums elsewhere in this catalog. Further down still sits hydroxypinacolone retinoate, a stable retinoic-acid ester sometimes marketed as a 'retinol alternative,' also at an undisclosed level. Niacinamide is stable, so the clear glass dropper is not a liability.
How it’s delivered
Air- and light-sensitive actives (vitamin C, copper peptides) lose potency fast in the wrong packaging, so delivery and the bottle are scored, not just what’s on the label.
