This is a 4-piece pack of overnight hydrogel / sheet masks designed to deliver deep hydration, firmness and glow while you sleep. Many versions are marketed under the name “Bio-Collagen Real Deep Mask” (by the brand BIODANCE) or generic equivalents described as “Bio-Collagen Overnight Face Mask.” For instance, one listing says: “Deep Overnight Hydration – Designed to work while you sleep, this mask replenishes moisture and restores elasticity for smoother, plumper skin by morning.”
✅ Key Benefits
Ultra‐deep hydration: The mask is infused with a high concentration of low-molecular-weight hyaluronic acid and collagen extracts, enabling moisture to penetrate more effectively.
Firming & plumping effect: The “bio-collagen” (especially ultra-low molecular weight) helps enhance elasticity and may smooth the look of fine lines and enlarged pores.
Improved skin tone & texture: Additional active ingredients like niacinamide and ferment filtrates (such as galactomyces) help brighten dullness, even out the complexion, and support skin barrier health.
Overnight convenience: The mask is designed for extended wear (3-4 hours minimum, ideally overnight), making it suitable for a “sleep-in” skincare treatment.
Good for all skin types: It’s often cited as being safe even for sensitive skin, since it avoids many irritants.
