Biodance vs Quasi Bio Collagen Face Mask: Which is better?

The Biodance Bio Collagen Face Mask and Official Quasi Bio Collagen Face Mask are overnight collagen face masks that promise to boost hydration, reduce the appearance of fine lines, and make your face look all dewy.

But do they both work? And which one is better?

I definitely have my own opinion on this, but today I’m looking at the science behind the face masks to work out which one is actually more effective.

How hydrolysed collagen works

The Biodance Bio Collagen Mask and Quasi Bio Collagen Mask both use hydrolysed collagen, which is collagen that has been broken down into small peptides that are easy to mix into water-based products, like sheet masks.

These peptides primarily act as humectants that form a thin, hydrating film on the skin’s surface, and they’re pretty powerful.

• Humectant: They are excellent at binding water to the very top layer of your skin.

• Film-Former: They leave a thin, flexible, invisible layer on your skin.

This film, combined with the occlusive environment of the mask itself (the physical barrier that locks everything in), creates a hydration lockdown. This stops water from evaporating out of your skin.

The result? The top layer of your skin swells up with moisture, making it look instantly smoother, plumper, and bouncier. That satisfying firming effect you feel is incredible hydration.

Feature	Biodance Bio-Collagen Real Deep Mask	Quasi Bio-Collagen Mask	Comparative summary
Key hydration technology	Hydrogel mask designed to solidify and turn transparent as ingredients are absorbed (can be worn up to 8 hours/overnight).	Hydrogel mask with similar long-wear technology, also designed to turn transparent as essence is absorbed.	Identical occlusion: both masks use the same core hydrogel delivery method, which is key to any long-term moisture benefit.
Collagen type	Ultra-low molecular weight collagen (as small as 243 Daltons).	Ultra-low molecular weight collagen.	Penetration advantage (claimed): Biodance publicly claims a smaller molecular size (243 Da), suggesting a slight edge in getting peptides into the upper epidermis.
Main hydrating agent	Oligo-hyaluronic acid (ultra-low molecular weight).	Oligo-hyaluronic acid (ultra-low molecular weight).	Identical efficacy: both use the most advanced, small-particle HA designed for deeper epidermal absorption.
Barrier-building ingredients	Galactomyces ferment filtrate, probiotics, niacinamide.	Galactomyces ferment filtrate, probiotics, niacinamide.	Identical long-term benefit: both formulas contain the same proven, gold-standard ingredients for skin brightening, barrier repair, and elasticity.
Specific clinical metrics	Publicly cited: 166% moisture increase after 150 hours.	No publicly cited metrics: marketing focuses on ingredients (collagen, niacinamide, ferments) and the hydrogel's visual transformation.	Key difference: Biodance offers specific, published (though proprietary) numbers, giving consumers a quantifiable reason to believe the mask's effects are long-lasting.

How effective is hydrolysed collagen?

Hydrolysed collagen is a powerful moisturising agent, but it’s not a long-term solution.

It’s not a restorative product that rebuilds structural collagen deeper in the dermis. That’s because the collagen sits on the skin, rather than penetrating it.

Hydrolysed collagen actually only increases hydration for about two to four hours — the effect fades as the film breaks down.

By comparison, hyaluronic acid and ceramides work within the stratum corneum — the outer layer of the skin — to hold water and strengthen the lipid barrier. Their effects can last six to eight hours or longer, depending on concentration and delivery method.

Debunking claims

The Biodance Bio Collagen Mask specifically markets its formula as being superior in absorption due to the size of its key molecules:

• Ultra-Low Molecular Weight Collagen: Biodance claims to use collagen peptides with a very small size (as low as 243 Daltons). The idea is that the smaller the molecule, the better it can penetrate the stratum corneum (the outermost layer of the skin). While topical collagen doesn't reach the deeper dermis to rebuild natural collagen, smaller peptides can theoretically penetrate the upper layers of the epidermis more effectively than larger ones, enhancing surface hydration and plumping.

• Oligo-Hyaluronic Acid: Similarly, Biodance uses ultra-low molecular weight hyaluronic acid, which is designed to penetrate deeper into the epidermis compared to high molecular weight hyaluronic acid, providing moisture across multiple surface layers.

There is limited research about Quasi, but those masks also use the advanced, occlusive hydrogel technology that presses the essence against the skin for hours. This prolonged contact time greatly enhances the absorption of all its ingredients, which include similar high-efficacy components like niacinamide and ferments.

Biodance has a specific molecular advantage, but both masks deliver powerful ingredients through the common advantage of prolonged hydrogel application.

Mask adhesion and wear

Both use bio-cellulose or a similar material that is prized for its excellent adhesion and close fit. The mask starts thick and slowly dissolves into the skin over several hours (three or four hours, or overnight).

This unique process is highly effective at delivering intense moisture.

Lasting hydration

Based on their ingredient lists, both masks offer high levels of hydration and are effective at smoothing and calming the skin.

• Biodance emphasises its precise low-molecular-weight ingredients, which the brand's own studies claim result in moisture effects that last for over 150 hours.

• Quasi relies heavily on the proven benefits of its galactomyces and niacinamide blend for brightening and barrier strength, alongside its collagen.

Which mask is more effective?

Both the Biodance Bio Collagen Mask and the Official Quasi Bio Collagen Mask use high-quality, similar formulations and hydrogel technology.

The Biodance mask delivers excellent surface moisture and smoothing benefits through its collagen content, which provides a temporary plumping effect.

The Quasi mask, like Biodance, uses a blend of collagen, galactomyces ferment filtrate, and niacinamide to support hydration and the skin barrier.

Because both products share core barrier-repairing and hydrating ingredients, both masks are effective for intense surface hydration and barrier support during long wear.

Which one is better value?

Collagen face masks are not long-term fixes for aging skin, but that doesn’t mean they’re not a quality addition to your skincare routine. The hydration and dewy glow they provide is almost unparalleled, even if it is only a short-term solution.

Topical hyaluronic acid is also a short-term solution, but I wouldn’t stop using that.

At the end of the day, Quasi and Biodance are very similar.

The key differences are cost and marketing claims. Biodance has more scientific data to back claims, while Quasi only really has claims.

At the time of writing, Biodance cost $19 for four masks, while Quasi cost $21.99 for eight masks.

Personally, I preferred Quasi because the sheet mask itself was thicker and more durable than the Biodance mask. But that was just my experience.

My recommendation? Pick whichever one is on sale.

Does K Republiq Glass Skin Really Work: A Review

Does K Republiq Glass Skin actually reduce the size of your pores and create a smooth complexion? I tried it out so you don’t have to.

As with a lot of products on this site, I came across K Republic Glass Skin on social media and decided I had to try it out. I’m always so curious to see if new products and fads work — at the moment, it feels like every second ad on Instagram is for a new product promising to give me Korean-style glass skin.

I decided to splash out on K Republiq because the products were created with extreme hydration in mind, which is what ultimately gives you that glass-like look. It’s basically advertised as a glass skin routine. The ingredients list is packed with polyglutamic acid which holds ten times more moisture in your skin than hyaluronic acid.

Bakuchiol helps reduce fine lines without drying your skin like retinol, niacinamide helps smooth pores, and vitamin C and squalene help illuminate and plump the skin. I was basically using all these products anyway, but now they’d be concentrated in single product line.

The ads feature women age 20 to 60 with pretty convincing before and after photos. Usually, models for these products are in their 20s with flawless skin, which doesn’t really show how well the products work for everyone. I’m in my 30s, which isn’t old, but my skin isn’t like it was in my 20s. I’m pasty pale, I live in a hot climate, I am very photosensitive, I have sun damage, mild rosacea, and fine lines. The product is marketed for people of for all ages and apparently it’s ten times more moisturising than hyaluronic acid.

K Republiq Glass Skin: A Review

I bought a kit with three pieces: Glass Skin Glazing Essence, Glass Skin Serum and Glass Skin Finishing Glaze.

Shipping was super fast and I had my kit within about three days. It also came with a free Gua Sha. I was happy to find the bottles were large and full to the top with product. They’re pink, bulky and hard to lose. The essence is a spray, the serum is a pump bottle, and the glaze is in an airless pump vacuum bottle — you push the lid down and product comes out the top.

I was going out one the evening I got the package so immediately washed my makeup off so I could use my new products underneath. Deep down, I was kind of hoping my skin would immediately transform into youthful radiance like it seemed to in the ads. Obviously that didn’t happen, but I think it did look a bit shinier…sort of glass-like, you could say.

According to the website, you’re supposed to spritz your face with essence and let it sink in before using about two pumps of the finishing glaze. My skin did feel a bit smoother with the glaze — it felt kind of tight on my face, but not in an uncomfortable way. Make up went smoothly over the top.

I was ready for the night routine when I got home. I washed the make up off, used the essence and a pump of the serum. The serum was pearly-white and went on very easily with my fingers. It dried pretty quickly before I used the glaze. Again, the glaze had the tight-ish feeling on my skin.

What happened

I repeated this routine for weeks, replacing all my products — hyaluronic acid, niacinamide, lactic acid, retinol, and agrilene — with K Republiq. I used the essence and glaze morning and night, adding the serum only in the evening. My skin felt noticeably smoother on the first day and the feeling never went away. Months later, my skin still feels really smooth.

By the end of the month, I was running low and decided to make the most of Black Friday sales. This time, I bought two kits which included the Magic Balm.

The mask is a very thick, pearly pink wax-like product that is very thick and melts in your fingers. I put way too much on the first time. A little goes a long way, it even says that on the packaging, but I can’t stress that enough — a little goes a long way. I put it on at night instead of the glaze, because it’s way too thick to go under makeup, and my skin is super smooth by morning.

Pros

Three products replace about seven, the products are packed with moisturizing and hydrating ingredients, and they’re vegan. When I asked my partner if the difference was visible, he said it did. My pores were smaller, mild redness had lessened, and it had a dewy glow about it. My skin didn’t get sick of it, I didn’t develop an allergy or intolerance to it, and I have noticed fine lines aren’t as visible.

Cons

The products are expensive. They’re large bottles that last a while, and you can also get some pretty decent deals on the site, but it’s still significantly more than The Ordinary, which costs about $12 a bottle. I initially paid $99 for the Glass Skin Glazing Essence, the Glass Skin Serum and the Glass Skin Finishing Glaze. I didn’t have to get the pack of three, but the finishing glaze on its own costs about $79, so it was better value to get the pack. I also decided the only way to find out whether the products really worked was to buy the whole routine. I went back about a month later to check out the Black Friday specials and the price was jacked to $119…go figure.

One thing I really didn’t like was the airless pump vacuum bottle the glaze comes in — it pumps well the first few times and then it’s impossible to get anything out of it. The jar does unscrew really easily so you can get every last bit of product out, but you shouldn’t have to do that. The pump function is as much to do with ease as it to do with portion control. The jar instructs you to use two pumps morning and night, and that’s not possible when the pump function doesn’t work. It’s a small problem, but worth mentioning.

Verdict

Krebuliq products really do work and I bought them again. Do I have flawless and glass-like skin? No. Do I still feel the need to wear makeup when I leave the house? Yes. It did not completely even out my skin tone, nor did it fix rosacea. I do not look like the women in the ads, even the ones who are twice my age. But it did help with my skin problems and I do feel as though it’s good for my skin. It looks healthy and vibrant, and it feels great.
