Galacto Niacin 97 Power Essence
Reviewed by SerumTruth Editorial · Price and formula checked July 2026
One of the more honestly dosed essences in the K-beauty aisle: two ingredients, both disclosed, both at levels that mean something. The ferment evidence is limited and mostly brand-led, but the niacinamide half is doing real, well-evidenced work. A good value pick for a hydrating, tone-supporting layer.

What’s inside
| Active | Disclosed | Dose |
|---|---|---|
| Galactomyces Ferment Filtrate (Pitera) | 92% | Clinical |
| Niacinamide | 5% | Clinical |
A two-ingredient essence, 92% galactomyces ferment filtrate plus 5% niacinamide, adding up to the "97" in the name, dispensed from an opaque pump bottle. Both numbers are brand-disclosed and both sit at genuinely high levels for their categories: 5% niacinamide is at the strong end of the studied range, and a 92% ferment base is about as concentrated as this ingredient gets. Because it carries no real preservative system beyond the essentials, Purito recommends refrigerating it after opening and using it up quickly. It is a hydrating, brightening-leaning first-essence step, not a treatment for texture or fine lines.
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.
The actives, explained
What the research says
In a small trial, a serum with this ferment filtrate plus other actives was linked to a better look of lingering dark spots after 8 weeks.

Topical 5% niacinamide was linked to more even looking skin tone, softer looking lines, and less visible blotchiness after 12 weeks.

A study of the active, not this exact product. What matters for the score is whether this serum uses it at a comparable dose.
