Bio-cellulose begins with microorganisms producing cellulose in a nutrient medium. That material then needs processing into a usable sheet before it becomes part of a finished cosmetic mask. Fermentation explains where the sheet comes from; shaping, formulation, and packaging explain how it becomes something you can use. Published mask research describes these as distinct parts of production. [1] [3]

At DAYBFOR, we use bio-cellulose for D-1. This is our brand Journal, and this guide looks at the general manufacturing story behind the material. It is not a factory tour or a record of D-1’s exact production settings.
1. Start with a medium that supports cellulose production
The starting liquid provides nutrients for cellulose-producing microorganisms. Coconut water is one example: EZ COSTEC describes its bio-cellulose sheet as made through coconut-water fermentation. That describes the origin of its material, rather than a recipe shared by every bio-cellulose manufacturer. [2]
Researchers also investigate other starting materials. In a 2025 study, Zhang and colleagues produced bacterial cellulose using a particular bacterial strain and evaluated brewing by-product hydrolysates as fermentation inputs. Their work illustrates why “bio-cellulose” does not identify one universal feedstock or production recipe. [1]
For a reader, this helps separate two questions: what feeds the process that makes the sheet, and what is included in the cosmetic formula you apply. A story about the starting liquid does not replace the finished product’s ingredient information.
2. Let fermentation build the cellulose material
During fermentation, the microorganisms make cellulose. The resulting material can form a hydrated network that is useful for preparing mask sheets. Production conditions matter: the 2025 study compared different cultivation approaches and found differences in cellulose production. [1]
There is a practical reason to avoid attaching one fermentation time to the entire category. A time reported in a paper belongs to that method; it is not automatically the timetable for a mask on a store shelf. The same caution applies to temperatures, sheet thicknesses, and other production details.
You can appreciate the material’s origin without needing a factory recipe. The key idea is that fermentation makes the cellulose material, while later steps prepare it for its role in a cosmetic product.

3. Process the material into a facial sheet
The material is processed beyond fermentation. Manufacturer documents describe washing, slicing, and shaping operations; published mask research describes partially removing water and cutting sheets with openings for the eyes, nose, and mouth. Those examples help explain how a cultivated material becomes a usable mask shape. [3]
These are broad operations, not a single production protocol. Their order and details depend on the method. A simplified diagram can show the transition from material to sheet, but it cannot establish the cleaning procedure, thickness, or quality checks used for every finished product.
Notice what changes here: the material now has a physical format for use on the face. That is a manufacturing achievement, separate from any claim about what the finished formula will do for skin.
4. Bring the sheet and formula together
A shaped sheet is still only part of the mask. In Perugini and colleagues’ research, prepared biocellulose sheets were combined with cosmetic solutions, folded, placed in sachets, and heat-sealed. The researchers prepared different formulations using the sheet format. [3]
This gives the manufacturing story a useful dividing line: making the carrier and developing the formula are connected tasks, but they are not interchangeable. A photograph of a sheet or fermentation vessel cannot tell you the complete contents of the pouch.
Quality also needs attention beyond the material name. A separate study by Perugini and colleagues examined methods for assessing the quality and safety of biocellulose mask systems. Its focus reinforces why the finished formulation deserves its own evaluation. Neither that research nor the studies cited here tested DAYBFOR D-1. [4]
What this means for your D-1 ritual
DAYBFOR is our brand; D-1 Bio-Cellulose Mask is our product. A “bio-cellulose mask,” also written “biocellulose mask,” takes its material description from the sheet. The manufacturing story helps explain that sheet’s origins. The product’s formula and directions tell you more about the mask you will actually use.
Our concept, The Night Before Your Big Day, gives D-1 a place in a considered evening routine. Understanding how the material is made can add meaning to that moment, without turning fermentation into a promise of a particular result by morning.
