Zymogen Fermented
ZYMOGEN builds its fermented skincare around a few different actives rather than one formula: Centella (in a serum, a 30ml essence, and a 50g cream), Fermented Soybean (an elastic 105ml serum), and Houttuynia cordata (a 105ml serum and a matching lotion). A Nourishing Fermented Toner and the Erseong Candle Fermented Lotion round out the line, so this collection groups every fermented-ingredient product ZYMOGEN sells in one place.

Buying Guide: ZYMOGEN Fermented Skincare
ZYMOGEN's fermented line is not one formula but several: Centella-based products, a Fermented Soybean serum, and Houttuynia cordata items, plus a toner and lotion. This guide sorts them by active ingredient and format so you can find the right step.
Three fermented actives in this collection
Rather than a single fermented formula, ZYMOGEN spreads this ingredient across three named actives: Centella (serum, essence, and cream), Fermented Soybean (an elastic serum), and Houttuynia cordata (serum and lotion). Knowing which active a product is built on is the fastest way to compare items in this collection.
The Centella Fermented lineup
Centella appears across three formats here: the Centella Fermented Serum, a 30ml Centella Fermented Essence, and a 50g Centella Fermented Cream. Together they can layer as serum, then essence, then cream, or you can pick just the step missing from your current routine.
The Fermented Soybean Elastic Serum
The Fermented Soybean Elastic Serum (105ml) is a separate formula from the Centella serum, built around fermented soybean rather than Centella. It sits alongside the plain 105ml Fermented Serum as one of the larger-format serums in this collection.
Houttuynia cordata serum and lotion
ZYMOGEN also fermented Houttuynia cordata into a 105ml serum and a matching 105ml lotion, giving you a serum-and-lotion pair built on that single plant ingredient rather than mixing it with the Centella or soybean items.
The Erseong Candle Fermented Lotion
The Erseong Candle Fermented Lotion is listed in a 105ml size and is a distinct formula from the Houttuynia cordata lotion, so check the product name closely if you are restocking a specific lotion rather than trying either at random.
Where the toner fits
The Nourishing Fermented Toner (105ml) is the first liquid step before any of the serums in this collection, whether you follow it with the Centella serum, the Fermented Soybean serum, or the Houttuynia cordata serum.
Comparing the serum sizes
Several serums in this collection ship at 105ml (the plain Fermented Serum, the Fermented Soybean Elastic Serum, and the Houttuynia cordata serum), while the Centella Fermented Serum is a separate listing. Matching the active ingredient, not just the size, is the more reliable way to pick the right one.
Building a routine from one active
To keep a routine consistent, pick one active and stay within it: toner then Centella serum then Centella essence then Centella cream, or toner then Houttuynia cordata serum then Houttuynia cordata lotion, rather than mixing actives step by step.
Who this collection suits
This collection suits shoppers comparing ZYMOGEN's fermented actives against each other, whether you already use one (Centella, fermented soybean, or Houttuynia cordata) and want the matching step, or are choosing between them for the first time.

Frequently asked questions
FAQ
Frequently asked questions
What's the difference between the Centella Fermented Serum, Essence, and Cream?
All three are built on Centella, but in different formats and steps: the serum is the concentrated treatment step, the 30ml essence is a lighter layering step, and the 50g cream is the final moisturizing step.
Is the Fermented Soybean serum the same as the Centella serum?
No, they are separate formulas. The Fermented Soybean Elastic Serum (105ml) is built around fermented soybean, while the Centella Fermented Serum is a different listing based on Centella.
What is the Houttuynia cordata serum and lotion pair for?
They are a matching 105ml serum and 105ml lotion, both built on fermented Houttuynia cordata rather than Centella or soybean, meant to be used together as one step of a routine.
Is the Erseong Candle Fermented Lotion the same as the Houttuynia cordata lotion?
No, they are separate 105ml lotions with different formulas, so check the exact product name if you are restocking one specifically rather than picking either at random.
Do I use the fermented toner before or after the serum?
The Nourishing Fermented Toner (105ml) is a first liquid step, applied before any of the serums in this collection, whether that is the Centella, Fermented Soybean, or Houttuynia cordata serum.
Does ZYMOGEN sell only Centella fermented products?
No, this collection covers three separate fermented actives from ZYMOGEN: Centella, fermented soybean, and Houttuynia cordata, plus a toner and additional lotion.
