The Biodance Bio-Collagen Real Deep Mask is a Korean hydrogel sheet mask that goes on opaque at night and turns transparent by morning as the essence absorbs. Each sheet carries 34g of hydrating serum loaded with low-molecular-weight collagen, hyaluronic acid, and galactomyces ferment (the same ferment SK-II's classic formulation is built on). The science is real: the brand cites a 256% hydration boost from a single overnight wear, and the in-use effect is a noticeably plumper, pore-minimized mo
Pros
- Hydrogel sheet melts into skin over 3 to 4 hours, no rinse needed in the morning
- 34g of essence per sheet, more than most competing overnight masks
- Visible plumping and pore-minimizing effect the morning after
Cons
- Sleeping on your side or stomach can shift the sheet before it fully absorbs
Frequently asked questions
Do I need to wash my face in the morning after using it?
No, the essence absorbs fully overnight. You can gently pat in any leftover residue or rinse if you prefer a clean canvas before makeup.
How many masks come in a pack?
The standard pack contains 4 individually wrapped sheets. Larger Costco-style packs are also available with up to 24 sheets.
Is it safe for sensitive or acne-prone skin?
The formula is fragrance-free and rated by the brand as suitable for sensitive types. Patch test on the jawline before a full overnight wear if you react easily.
Can I use it after a retinol or acid night?
Yes, many users layer it on top of mild acid or retinol routines to buffer dryness. Skip if your skin is actively irritated or peeling.
