The Biodance Bio-Collagen Hydrogel Overnight Face Mask four-pack has been reduced from £14.90 to £11.99 on Amazon, averaging under £3 per mask. The viral Korean skincare product is described by shoppers as smoothing wrinkles and leaving skin looking plumper.
Popular Korean mask with global sales
Korean skincare has remained popular in 2026, and the Biodance masks are among the most sought-after. The brand claims to have sold more than 300 million masks worldwide since launching in 2021.
The masks are designed to be worn for three to four hours, or overnight, and turn transparent during use, unlike conventional sheet masks that are removed after about 15 minutes.
Biodance founder Mihwa Kim created the sheet-free hydrogel mask after receiving treatment for facial scarring following a car accident that required 60 stitches. She adapted hydrogel patch technology used in scar treatment for skincare purposes.
What the mask promises and what shoppers say
The Bio-Collagen Real Deep Mask aims to moisturise the skin, visibly enhance elasticity, and deliver a smoother, more luminous complexion. Its formulation includes oligo-hyaluronic acid for moisture, probiotics to support the skin's protective barrier, and ultra-low-molecular-weight collagen to minimise enlarged pores, boost elasticity, and reduce the appearance of fine lines and wrinkles.
The masks hold a 4.4-star rating from over 48,000 global reviews. One customer wrote: "Really lovely product. My skin was glass like when I removed this mask. It's soft and cooling on skin, fits face well, and the little eye and mouth cut out bits can be saved and used under eye patches. Good quality item and value for money, Put it on go to bed wake up with hydrated smooth skin, very effective."
Another reviewer noted the masks are "fiddly" to use but left a five-star review, stating: "My mom uses these collagen masks and they are so effective. Her skin looks so much plumper and shiny. It's a little fiddly to use as the mask is divided into two parts but otherwise no complaints. It is a little pricey but when they are on sale they are a great bargain."
Time commitment and alternatives
A potential drawback is the time required for the mask to take effect, with users needing to set aside several hours during the day or apply it overnight. One five-star review said: "At first it's very soft and needs gentle handling. After about an hour it stays on your face. After 3 hours or so it becomes transparent and it's time to take off. It leaves your skin hydrated and even smoothes out a few wrinkles. It gives you a glowing and dewy affect and the result last about a week for me."
Another review read: "I am big face mask fan, always trying something new. This is a face mask that I would give rating ten out of ten. I have dry, mature skin. I kept the mask on for four hours and I didn't exect any miracles, but a miracle happened. When I took of the mask, my face looked fresh and younger."
