BLANC DUBU Nuborn Cell Hydrogel Collagen Neck Mask with hADSC-CM Stem Cell Marine Collagen 9-Peptide Firming Brightening Neck Wrinkle Patch All Skin Types 5 x 0.49 oz

TARGETED NECK CARE POWERED BY STEM CELL SERUM IN HYDROGEL FORM The neck is one of the first areas to show visible signs of aging — yet most skincare routines skip it entirely. BLANC DUBU Nuborn Cell Hydrogel Collagen Neck Mask is a serum-infused extended wear hydrogel designed to visibly firm, hydrate, and brighten the neck area. Over 375,000 neck masks sold in Korea. FORMULATED FOR Dry or flaky skin | Visibly sagging skin | Skin that becomes red and sensitive due to external factors | Uneven, patchy skin texture | All skin types KEY FORMULA hADSC-CM (Human Adipose Stromal Cell Conditioned Media) — A bioactive conditioned medium derived from human adipose stem cells, manufactured in a GMP-grade facility. Known to help support the appearance of skin renewal and help visibly maintain the skin's natural barrier function. Marine Hydrolyzed Collagen (500 Daltons) — Low molecular weight marine-derived collagen with enhanced skin absorption properties. Acts as a water-binding humectant to visibly plump and smooth the skin. 9-Peptide Complex + 6-Type Hyaluronic Acid — 9 synergistic peptides (including Palmitoyl Pentapeptide-4, Copper Tripeptide-1, and Acetyl Tetrapeptide-5) help visibly support the appearance of skin elasticity. 6 molecular weights of hyaluronic acid deliver hydration from the skin surface to deeper layers. CLINICAL TEST RESULTS The following data is from an independent clinical study conducted on the Nuborn Cell Hydrogel Collagen Mask, which shares the same core active formulation as the Neck Mask. Test conducted by SKINMED Co., Ltd | 22 adult women, ages 20–60 | 2 weeks of use | No adverse effects reported. 37% IMPROVEMENT IN SKIN MOISTURE | 20% IMPROVEMENT IN SKIN LIFTING | 6% IMPROVEMENT IN SKIN BRIGHTENING Individual results may vary. KEY DIFFERENTIATOR Unlike conventional wet sheet masks, the Nuborn Cell Hydrogel Neck Mask is a serum in hydrogel form — active ingredients are built directly into the mask material. The 1.20mm thick hydrogel helps prevent water evaporation, enabling deeper and more sustained absorption. The flexible sheet can also be trimmed and applied to targeted areas beyond the neck — including under eyes, cheeks, and forehead. TEXTURE AND SENSORY Gel-like and smooth on first contact, with a gentle cooling sensation. Lightweight and non-oily — does not feel heavy or greasy. As wear time increases, the mask gradually becomes transparent, indicating full absorption of the built-in serum. No sticky or oily residue after removal. HOW TO USE Step 1. Cleanse skin thoroughly. Do not apply serums or creams beforehand — apply directly on completely dry skin immediately after cleansing. Step 2. Apply the mask to the neck area. For best adhesion, remain still for 10–15 minutes. Lying flat helps. Step 3. Wear for a minimum of 20–30 minutes. For intensive care, extend to 2–3 hours. Step 4. Remove mask. No rinse needed. When the mask becomes transparent, essence is fully absorbed. Step 5. Optional: Trim the flexible hydrogel to fit targeted areas such as under eyes, cheeks, or forehead. Use caution when cutting. Step 6. Recommended frequency: 3 times per week, or daily for intensive conditioning. CERTIFICATIONS Korea MFDS-Registered Dual-Function Cosmetic (Brightening + Wrinkle Improvement).
