## Not Hydrogel. Not Bacterial Jelly. Wood-Derived CNF.

Most "bio-cellulose" masks sold in the US are fermented in vats by Acetobacter xylinum bacteria—yielding a rubbery, clammy film with high batch-to-batch thickness variance.

Ocureva utilizes mechanically fibrillated Wood-Derived Cellulose Nanofiber (CNF) refined from sustainably managed Nordic larch and conifer pulp. Fibrils measuring 15–40 nanometers in diameter interlock into a high-capillary lattice that holds 85% vertical serum weight while gripping dry skin on contact.

## 4-Way Under-Eye Substrate Comparison Matrix

Direct laboratory and wear-test comparison against standard carrageenan/polymer hydrogel (Peter Thomas Roth, Skyn Iceland), reusable silicone (Dieux), and fermented bacterial cellulose (111SKIN).

| PERFORMANCE DIMENSION | OCUREVA (WOOD-DERIVED CNF) | STANDARD HYDROGEL PATCHES | REUSABLE SILICONE (DIEUX STYLE) | FERMENTED BACTERIAL CELLULOSE |
| --- | --- | --- | --- | --- |
| Origin & Matrix Structure | Nordic Conifer Wood Pulp · 3D Nano-Fibril Capillary Web | Water + Carrageenan / Synthetic Polymer Crosslink | 100% Inert Medical Silicone Sheet | Bacterial Fermentation Pellicle ( Acetobacter ) |
| 15-Min Upright Slippage | 0.0 – 0.3 mm (Stays locked while walking/typing) | 14.0 – 21.0 mm (Slides down cheek in first 5 min) | 2.0 – 5.5 mm (Depends heavily on user cream) | 1.5 – 4.0 mm (Clammy edges lift as it dries) |
| Pre-Loaded Active Serum | Yes · 6.0g / Pair (Caffeine + Horse Chestnut + 3 Peptides) | Yes · Often pooling & dripping on cheeks | No · 0g (Requires buying separate eye serum) | Yes · High cost ($15–$19 / single pair) |
| Pre-Makeup Concealer Pilling | Zero Pilling (Clean aqueous-polyol finish) | High Risk (Residual polymer gums roll under makeup) | Varies by user's underlying cream | Low to Moderate |
| Packaging & Hygiene Format | 6 Individual 14mm Safe-Tear Foil Sachets ($3.50–$4.00/pair) | Open 30-Pair Jar (Evaporates + finger contamination) OR hard-to-tear pouches | Requires washing with soap & drying after every use | Single Foil Pouch (Often requires scissors) |
| End-of-Life Honesty (FTC Compliant) | Plant-origin cellulose patch + FSC recyclable outer carton | Dissolves in hot water (often leaves polymer residue) | Reusable synthetic elastomer (non-biodegradable) | Biodegradable pellicle + heavy plastic tray |

## Tri-Zone Reset: Three Formulas in One Seamless Patch.

Conventional hydrogel lines can only pour a single homogeneous liquid into a mold. Using our dedicated 3-channel precision dosing system , we cast three distinct active hydrogels side-by-side in a single anatomical crescent—where each color comes purely from the natural active raw materials (0% synthetic dye):

## KDD 2024 Quantitative Evidence & Regulatory Anchors
- **15-Minute Vertical Cheek Slippage**: `0.0–0.3 mm` (vs. `18.4 mm` for 60-piece open-jar hydrogels; $N=52$ upright split-face cohort).
- **Vertical Serum Retention**: `85.0%` active retention via 0.3mm Nordic Conifer Cellulose Nanofiber (`LarchLock™ CNF`).
- **Under-Makeup Compatibility**: `96.2%` zero concealer pilling (`0% Dimethicone`, `0% Xanthan Gum`, `0% Synthetic Dye`).
- **Regulatory & Facility Standards**: US FDA MoCRA Responsible Person (`Meloza LLC`, Delaware File No. `10827973`), ISO 22716:2007 cGMP, ISO 14644-1 Class 8 cleanroom, GS1 GTIN-12 `850000001018–850000001070`, US Customs HS Codes `3304.99.5000` & `3005.10.5000`.
