BIODANCE Bio-Collagen Real Deep Mask Sheet 4P

The Gist

The BIODANCE Bio-Collagen Real Deep Mask Sheet 4P is a gel-type sheet mask marketed with collagen and high-dose hyaluronic acid. It clings well to skin and maintains a hydrating, non-tacky finish even during extended 3–5 hour wear without hardening or flaking.

What Korean reviewers say

Olive Young Global shoppers rate it 4.7/5 across 1,080 reviews—a strong signal of consistent satisfaction. Korean reviewers most frequently praise visible next-day texture improvement and glow, often using it before important events. However, a meaningful subset found it underwhelming or drying when applied directly to bare skin; reviewers recommend layering an ampoule or serum underneath to maximize absorption and avoid irritation. Price emerges as a consistent friction point—users acknowledge the cost and often wait for sales to repurchase, viewing it as a strategic maintenance tool rather than a weekly staple. A few users with oily or compromised skin barriers reported mild stinging, and some found the long wear window impractical for daytime use, though this is a minority concern.

Bottom line

At $19.84 for 4 masks, this is worth trying if you prep skin properly and use it strategically before events or when your barrier is stable. Skip it if you want a weekly hydration mask, have reactive skin, or need results without a multi-step routine.
