Time Revolution The First Essence 5X
Reviewed by SerumTruth Editorial · Price and formula checked July 2026
The essence most often called Missha’s answer to SK-II, and the comparison holds past the marketing into the ingredient list: a high-percentage yeast ferment base carrying an unusually prominent niacinamide inclusion. Evidence for any single proprietary ferment is limited and mostly brand-generated, same as the category leader, but at well under half that essence’s price for a comparable size, it is a fair way to try the format.

- Galactomyces Ferment Filtrate (Pitera): limited evidence
- Niacinamide: moderate evidence
The average of the key actives’ evidence grades.
- Potency21 / 25
Dosed at studied levels, not fairy-dusted
- Galactomyces Ferment Filtrate (Pitera) (97%): dosed at a studied level
- Niacinamide: dosed at a studied level
How strongly the actives are dosed, led by the strongest, not how many there are.
- Delivery & stability14 / 20
Delivery tech + packaging that protects fragile actives
- Delivery: standard
- Packaging: clear dropper
- No fragile actives here, so packaging barely moves the score.
Delivery tech plus packaging, and packaging only counts when actives are fragile.

What’s inside
| Active | Disclosed | Dose |
|---|---|---|
| Galactomyces Ferment Filtrate (Pitera) | 97% | Studied |
| Niacinamide | n/a | Studied |
Now in its fifth generation, brand-stated at 97% Desert Cica Yeast Ferment produced through Missha’s own three-step fermentation process, with niacinamide listed third on the INCI ahead of water, plus bifida ferment lysate, adenosine and a small ceramide NP addition, in a clear glass bottle poured into the palm like a toner. The yeast ferment is not identified to species on the label, so it is mapped here to the galactomyces-ferment slug as the closest cataloged fermented-essence analogue, not a literal Pitera match. Niacinamide’s exact level is not disclosed, but its position ahead of water on the ingredient list points to a meaningful, not token, dose.
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.
