| Saccharomyces Ferment Filtrate | Kombucha Ferment | |
|---|---|---|
| What it is | Close cousin of galactomyces and the reason first essences exist at all. Yeast ferment filtrates are conditioning ingredients — read the marketing about 'cell renewal' as appearance language, not a proven biological claim. | Fermented sweet tea, filtered and put in an essence. It brings green tea polyphenols plus the acids and sugars fermentation produces, which is a plausible mix for surface conditioning. The evidence for kombucha specifically, as opposed to green tea or ferments in general, is slim. A pleasant ingredient with a good story attached. |
| Best for | Dullness & glow, Rough & uneven texture, Anti-ageing & firmness | Dullness & glow, Rough & uneven texture, Damaged moisture barrier |
| When to use | BOTH | BOTH |
