Well, you're not alone. I finally gave in and decided I simply needed to test the Biodance Bio Collagen-Real Deep Mask myself - and the results didn't disappoint.

This deeply hydrating collagen mask comes in two sections to allow you to mould it perfectly to your face, and it even has some off cuts to ensure there's so missed areas

Why are these masks going so viral? Thanks to Korean skincare absolutely dominating the market right now, people can't get enough of the glowy, glass-skin look these masks claim to provide. 

This mask transforms from a serum-saturated gel mask to a transparent sheet mask while it sits on your skin, providing you with hydration that lasts long after you've taken it off. 

It's formulated with Oligo hyaluronic acid, a low molecular humectant that provides fast, deep skin penetration, making it more effective than traditional hyaluronic acids - it even helps to maintain or restore the skin's moisture barrier. 

The ingredient that makes this mask so popular? Collagen. The low mollecular collagen refines the look of enlarged pores and fine lines by enhancing skin elasticity for smoother-looking skin. 

And you can use it in the day or overnight. Simply leave it on while you sleep and wake up with deeply nourished skin, or you can apply it during the day after your toner or serum, leave it on for three to four hours, and voila! Glass skin.

What did commerce writer, Phoebe really think of these viral masks? 

The mask dries completely clear (the white patches are where there is a double layer of sheet). 

I've used this mask a few times now, and I have to say that I'm thoroughly impressed - my skin felt plump and hydrated for ages after, and it really goes give the illusion of glass skin - I've quite literally never seen my skin look so glowy or smooth. 

I prefer applying this in the morning, let it sit on my face until it turns clear, and then removing it instead of using. I feel like my makeup looks better than ever after applying, as it's so hydrated and smooth that I don't even need to use primer, it simply glides on and blends out easier than ever. 

I also really like that they're easy to cut, which makes it help fit better around the eyes and nose.  

That said, it does have it's drawbacks. It was extremely finnicky to place on the skin the first time, since it was much more wet and slimy than I had anticipated - to the point I almost gave up, but eventually managed to get it on fine. I imagine like a lot of things, it will get easier the more I use them. 

The main selling point for me with these was that you can (supposedly) wear them overnight, however as a side and front sleeper, this did not work out well for me. I woke up in the middle of the night with the mask plastered to my pillow, instead of my face, meaning I was left dissapointed that I didn't get the full benefit. 

Back sleepers however, you will love this. 

Overall, I really love these sheet masks, and despite the fact it takes a little getting used to application-wise, it quickly becomes a non-issue, and the results are quite literally unlike anything else I've ever used. 

You can wear during the day or overnight, making this a versatile option when you want some ultra-deep hydration, and your skin is left looking hydrated and glowy after removal 

And from the reviews, it's clear customers are also loving these, with one saying, 'I had read so many great reviews about this mask that I decided to give it a try—and I’m so glad I did. The mask comes in two parts, which makes it easy to apply and ensures a better fit on the face.'

They continued, 'I found that leaving it on a bit longer really enhances the results. After using it, my skin felt incredibly soft, refreshed, and rejuvenated—just like after a luxury spa treatment.'

'Saw these on TikTok and was intrigued to see if they actually live up to the hype and they definitely do! The only sheet masks I’ve used that stay on my face and left my skin feling so smooth And hydrated', claimed another happy customer. 

A third added: 'Bought into the hype and love them! Used overnight, stayed on my face with no issue and woke up to glowy skin'
