Hello, this is a hydrogel formulation researcher from OTCM.
The mask market is rapidly shifting from traditional nonwoven sheets toward
hydrogel. As demand for high-performance at-home skincare continues to grow
globally, premium hydrogel masks are emerging as a next-generation product
category in K-Beauty.
If you have ever wondered, “Why does a sheet mask dry out and start lifting
after just 20 minutes?”, you are not alone.
In this edition, we take a closer look at the structural limitations of conventional
nonwoven sheet masks and the technological differences that hydrogel formulations
bring to the category.

point 1
|
The Structural Limitations of Conventional Sheet Masks
|
|
Conventional nonwoven or cotton sheet masks are made by saturating a fibrous sheet
with liquid essence.
Because the sheet does not perfectly conform to every contour of the skin, it can
easily lift away from the surface. Over time, the essence can also evaporate into
the surrounding air. When worn for more than 20 minutes, the sheet may begin to dry
out, potentially drawing moisture away from the skin's surface.

The Key to Close Adherence
: A 3D Hydrophilic Polymer
Network
|
|
Unlike a fabric sheet soaked in essence, hydrogel is a gel formulation that itself
contains a high level of water.
Plant-derived polysaccharides such as carrageenan and locust bean gum form a dense
3D network structure within the gel. This structure closely conforms to the skin's
micro-contours, helping minimize gaps and moisture loss. It also stays securely in
place without easily slipping or running during wear.

point 3
Active Ingredient Release:
A Temperature-Responsive
Delivery System
|
|
When hydrogel comes into contact with the skin, it responds to skin temperature
(36.5°C). Active ingredients held within the gel structure are designed to
gradually release in response to temperature, supporting their delivery to the skin
surface and into the skin. Compared with simple topical application, this delivery
system is designed to enhance the efficiency of active ingredient
delivery.
|
point 4
|
Moisture-Locking Barrier for Overnight Wear
|
|
A natural polymer matrix with excellent water-retention properties forms a
moisturizing occlusive barrier over the skin. By limiting contact with external air,
it helps reduce moisture evaporation. This makes hydrogel suitable not only for
extended treatments of 30 minutes or more, but also for overnight mask use, helping
maintain a hydrated feel throughout wear.
|
point 5
|
Superior Wearability with a Non-Slip Fit
|
|
Unlike conventional sheet masks, where excess essence can sit on the surface or
drip around the chin, hydrogel uses the natural adhesion of the gel itself to
provide
a more stable fit. This allows users to continue everyday activities, such as doing
household chores or working, while wearing the mask, creating a more comfortable
and convenient masking experience.
|
point 6
|
B2B Advantage Through Premium Positioning
|
|
Unlike the highly price-competitive conventional sheet mask market, hydrogel masks
offer brands an opportunity to differentiate through advanced formulation technology
and a distinctive texture. This differentiation can support a more premium price
pointp while creating opportunities to increase average selling price (ASP) and
improve product margins.
