Hydro Cera-nol Real Deep Mask: Overnight Hydrogel Mask for Hydration & Barrier Repair with Cera-nol Ceramides
The Hydro Cera-nol Real Deep Mask is an overnight hydrogel mask built on Biodance's patented Cera-nol barrier complex — D-Panthenol, 5 types of ceramide, and 10 types of oligo-hyaluronic acid — reinforced with 50,000 ppm glacial water. A single sheet is clinically shown to retain hydration for up to 150 hours, making it Biodance's dedicated answer for sensitive, red, dry, and barrier-weakened skin.

What It Is and Who It's For
The Hydro Cera-nol Real Deep Mask belongs to Biodance's Cera-nol franchise line, the lineup engineered around barrier repair rather than collagen firming. Where a standard sheet mask soaks a woven cloth in essence, this is a solidified hydrogel — the essence itself is the sheet. As you wear it, the opaque gel turns transparent and dissolves toward a milky essence with a radiant finish and an instant cooling feel.
It is built for the skin type that "drinks" toner and serum yet still feels tight, looks red, and reacts easily: sensitive, persistently reddened, dry, and barrier-weakened skin. If your skin feels only surface-hydrated even after re-applying products, the issue is usually a compromised barrier that cannot hold water — exactly what the three-part Cera-nol system is designed to rebuild.
Hero Ingredients: The Cera-nol Complex
Cera-nol is Biodance's unique barrier complex. It delivers triple-action barrier care by addressing three different failure points of compromised skin at once: moisture loss, a damaged lipid barrier, and active irritation.
| Component | Specification | Role |
|---|---|---|
| 10 types of Oligo-Hyaluronic Acid | Approximately 400x smaller than regular hyaluronic acid; confirmed by 13C-NMR to retain the same structure as full-molecular HA; protected under KR Patent No. 10-1145394 ("stem cell activity and regeneration-promoting composition containing oligo-hyaluronic acid") | Hydration — reaches multiple skin depths to address moisture loss |
| 5 types of Ceramide | Ceramide NP, Ceramide NS, Ceramide AS, Ceramide AP, Ceramide EOP | Barrier — ceramides sit between cells in the stratum corneum to block irritants and prevent moisture loss |
| D-Panthenol | The bioactive D-form isomer of provitamin B5; superior skin absorption versus racemic DL-Panthenol (only ~50% active D-form) and L-Panthenol (very low activity); pharmaceutical-grade soothing | Soothing — calms irritated, reddened skin |
| Glacial Water | 50,000 ppm; naturally purified spring/glacial water, low in impurities, rich in minerals (magnesium, calcium, potassium) and antioxidants | Soothing, barrier support, and moisture retention |
| Naturally derived cooling agent | Non-menthol; fennel (Foeniculum Vulgare) seed extract, coriander (Coriandrum Sativum) extract, cardamom (Elettaria Cardamomum) seed extract, saffron (Crocus Sativus) flower extract | Instant cooling without the irritation risk of menthol |
Why three actives instead of one
A barrier-weakened complexion fails in three ways at once. The 10 oligo-hyaluronic acids replace the water; the 5 ceramides rebuild the lipid "mortar" that holds water in; and D-Panthenol calms the inflammation that drives redness. Treating only one of these — hydration without barrier, or soothing without water — leaves the skin to relapse. Cera-nol covers all three in a single sheet.
Clinical Results

| 8-hour wear safety | Clinically proven for over 8 hours of use |
How It Works: The Transforming Hydrogel
The mask starts as an opaque gel and turns transparent during wear. That transition is the visible evidence that water and actives are leaving the gel matrix and entering the skin. Because the gel is the essence in solid form, it blocks evaporation and holds the Cera-nol actives against the skin for hours rather than the 15–20 minutes a fabric sheet can sustain.
Biodance set the sheet weight at 34 g after more than 80 tests across 3,240 hours of formulation work — the equilibrium point where the gel stays active and contour-adhered through a full night without sliding off. The matrix is PEG-free and made with naturally derived ingredients; in internal testing, PEG-containing masks increased skin redness by 89.39% versus PEG-free formulas, which is why the Cera-nol mask avoids them entirely. This is the brand's 4th-generation No-Mesh format, a step beyond the 1st-generation woven sheet.
How to Use
Overnight Protocol (Recommended)
- Cleanse and pat skin dry.
- Prep with toner and a lightweight serum. Skip heavy creams or oils that film over the skin.
- Open and unfold the hydrogel halves; the gel is tacky, not wet.
- Apply the upper half to the eye/forehead area and the lower half to the chin and jaw, pressing gently to contour.
- Sleep in the mask for up to 8 hours — it is safety-verified for over 8 hours of wear.
- Remove in the morning, pat in the remaining essence, and follow with sunscreen.
Daytime / After-sun Protocol
Apply after cleansing and wear for 3–4 hours, or until the gel turns transparent. This is a strong option for soothing after heat or sun exposure, where the +21.14% heat-damaged soothing benefit is most relevant.
Cera-nol Routine Synergy
The mask is the deepest-delivery step in the Cera-nol barrier routine. For consistent day-to-day barrier support between mask nights, layer it with the rest of the line:
- Cera-nol Gel Toner Pads ($26) — daily ceramide-and-hydration prep step.
- Hydro Cera-nol Serum ($21.90) — a Cera-nol serum clinically shown to increase hydration 524%; apply before the mask so its lightweight molecules go on first and the mask seals them in.
For a weekly regeneration boost, the Rejuvenating Caviar PDRN Real Deep Mask can be used as a separate step on alternate nights.
Frequently Asked Questions
What is the Cera-nol complex?
Cera-nol is Biodance's triple-action barrier complex: D-Panthenol for soothing, 5 types of ceramide (NP, NS, AS, AP, EOP) to rebuild the barrier, and 10 types of oligo-hyaluronic acid for multi-depth hydration. It targets moisture loss, a damaged barrier, and irritation together in one sheet.
How long does the hydration last?
A single sheet delivers up to 150 hours of hydration, with 166% of the benefit still retained after 150 hours. Moisture retention across 15 stratum corneum layers rose 114.77%, and an 8-hour overnight wear measured a 91.69% hydration boost.
Is it safe for sensitive, easily reddened skin?
Yes — it is designed for exactly that skin type. It is EWG Green Grade, dermatologist tested, MFDS-allergen free, free of 19 controversial ingredients and 20 Hwahae ingredients to avoid, and skin-irritation tested. Heat-damaged-skin soothing improved 21.14% after one use.
Can I sleep in it?
Yes. It is a sleeping-capable hydrogel clinically proven for skin safety during over 8 hours of use. Apply last in your evening routine and remove in the morning.
Does the cooling come from menthol?
No. Cooling comes from a naturally derived, non-menthol agent based on fennel, coriander, cardamom, and saffron flower extracts, chosen to avoid menthol-related irritation.
How is it different from a normal sheet mask?
It is a 4th-generation No-Mesh hydrogel with no fabric carrier — the essence is the sheet. It is PEG-free, turns transparent as actives absorb, and uses a 34 g weight refined over 80+ tests and 3,240 hours so it stays put overnight.
Bottom Line
The Hydro Cera-nol Real Deep Mask is Biodance's barrier-repair benchmark: a PEG-free overnight hydrogel that pairs the patented oligo-hyaluronic acid system with a full ceramide set, D-Panthenol, and 50,000 ppm glacial water. With up to 150 hours of retained hydration and a 99% satisfaction rate, it is the Cera-nol line's answer for sensitive, red, and barrier-weakened skin.
