I Swear This Korean Collagen Mask Took 5 Years Off My Skin (and It's On Sale RN)


I can't think of another beauty product more prominent on social media than Biodance's Bio-Collagen Real Deep Mask. Over the last year or so, I've seen countless skin experts and content creators talk about it. It's no wonder it sold out multiple times on Amazon. I was part of the unlucky crowd who had to wait for it to be restocked before I could test it out for myself.
Once I did, though, I understood the buzz. The Korean collagen mask is soaked in a serum-like solution that hydrates, plumps, smooths, and brightens the skin overnight. And I mean that quite literally—this mask is designed to be worn for hours at a time or overnight for best results. Come morning, I was convinced it took five years off my face. (You can see my results below.)
If you've been curious about the internet's favorite face mask, now's the time to try it because it's on sale through March 31 as part of Amazon's Big Spring Sale.
According to the brand, a full 1.19-ounce ampoule is used in a single Biodance Bio-Collagen Real Deep Mask. It contains four hero ingredients: oligo-hyaluronic acid, ultra-low molecular collagen, galactomyces ferment filtrate, and niacinamide.
- Oligo-Hyaluronic Acid: A form of hyaluronic acid that has an extremely low molecular weight and can deeply penetrate the skin
- Ultra-low Molecular Collagen: A form of collagen with an extremely low molecular weight that can deeply penetrate the skin to improve firmness, boost elasticity, and reduce fine lines and wrinkles.
- Galactomyces Ferment Filtrate: An antioxidant-rich yeast extract that brightens dullness, reduces hyperpigmentation, and improves skin texture
- Niacinamide: Also known as vitamin B3, it improves everything from acne to hyperpigmentation, signs of aging, inflammation, and enlarged pores
This unique and effective combination of active ingredients explains why the Biodance Bio-Collagen Real Deep Mask offers so many skin benefits. It can hydrate, firm, minimize the appearance of pores, and boost the skin's glow.

When you apply the mask, it's opaque white. It's also damp and slippery, like any other hydrogel mask. That's why, if you wear it overnight, I recommend putting it on about 30 minutes before bed so it can dry a bit and securely stick to the skin.
7 AM The Next Morning
After wearing it for a few hours (or overnight like me), it turns transparent. I took this picture at 7 AM, immediately after I got out of bed and before I poured my first cup of coffee. I was shocked that it stuck to my skin all night, even through tossing and turning. It really feels secure on the skin once it dries down.
The Result
After removing it, you're left with the smoothest, plumpest, glowiest skin. IMO, it looks like I just got a facial, even though I had actually just woken up from a too-short sleep. Even my dark circles were less prominent than they usually are.
I don't use these masks nightly. I don't even use them weekly. I reserve them for special occasions or whenever I want my skin to look exceptional. And believe me when I say these masks perfectly prep the skin for makeup. After wearing one, my foundation and concealer melt onto my face like butter.
There are two other iterations of the iconic Korean collagen mask. The first one is this Sea Kelp one, which is good for calming skin, controlling oil, and treating and preventing breakouts.
This version contains ceramides, oglio-hyaluronic acid, and D-panthenol to deeply hydrate the skin.
