Bio-Cellulose Technology

Not Just a Sheet Mask— It Feels Like a Second Skin.

Bio-cellulose is a premium mask material created through fermentation. Its ultra-fine fibre network forms a soft, flexible sheet that closely follows the contours of your face and helps hold the moisture-rich essence against your skin.

How Bio-Cellulose Is Different

An ultra-fine fibre structure made for better skin contact.

Unlike many traditional paper or nonwoven sheet masks, bio-cellulose forms a fine, flexible network that can hold a generous amount of essence while maintaining close contact with the surface of the skin.

Fermentation-Derived Material

Made using a fermentation process that creates an exceptionally fine and uniform cellulose structure.

Ultra-Fine Fibre Network

The three-dimensional fibre mesh produces a smooth, soft and flexible mask surface.

Second-Skin Adherence

The sheet follows facial contours closely, helping the essence remain in contact with difficult-to-fit areas.

High Moisture-Holding Capacity

Designed to retain moisture and support a deeply hydrating, spa-like skincare experience.

Moisture Retention

The bio-cellulose structure can hold a generous amount of essence and helps keep the sheet moist throughout use.

Breathable Comfort

Soft and flexible material creates a comfortable facial fit while helping reduce gaps between the mask and skin.

Soft and Durable

The elastic sheet is designed to remain intact, flexible and comfortable during your skincare ritual.

Thoughtful Material

Bio-cellulose is promoted as a biodegradable, naturally derived alternative to many conventional synthetic mask sheets.
