Summary
- The Biodance Bio-Collagen Hydrogel Overnight Face Mask is on sale for under £3.
- Over 300 million units of the viral mask have been sold globally.
- Founder Mihwa Kim developed the mask after a car accident caused scarring.

A viral Biodance Bio-Collagen Hydrogel Overnight Face Mask, which has achieved over 300 million global sales, is currently on offer for less than £3 per unit. Originally priced at £14.90 for a four-pack, the masks are now £11.99 on Amazon, making them a more accessible luxury.
These masks are distinct for their ability to gradually turn transparent during wear, a feature aligning with the 'morning shedding' social media trend. Biodance founder Mihwa Kim was motivated to create this unique hydrogel mask after sustaining facial scarring from a car accident requiring extensive stitches.
The Bio-Collagen Real Deep Mask aims to hydrate skin, boost elasticity, and promote a smoother, more radiant complexion. Its formula incorporates oligo-hyaluronic acid for hydration, probiotics for skin barrier support and anti-aging, and ultra-low-molecular-weight collagen to refine pores and smooth fine lines.
Shoppers have rated the masks highly, praising their hydrating and smoothing effects, with results lasting up to a week for some. However, users note they can be fiddly to apply and require several hours or overnight wear. Alternative hydration solutions include COSRX's snail mucin masks and Laneige's Water Sleeping Mask.
