Unless you’ve been living under a Wi-Fi-blocking rock, chances are you’ve scrolled past that video. You know the one, where someone peels off a glistening, jelly-like sheet from their face to reveal skin so smooth, dewy and practically reflective, you could mistake it for a glazed donut.

No filters. No ring lights. Just one hashtag away from viral.

The skincare star behind the magic? Biodance, the South Korean beauty brand turning collagen into content gold.

Their Viral Collagen Mask, officially known as the Bio-Collagen Real Deep Mask, has become a sensation on TikTok, racking up millions of views and rave reviews. It’s been dubbed everything from “the secret to glass skin” to “a face lift in a sachet,” causing the skincare-obsessed ask: Is this the real deal or just another internet-fueled fad?

The Biodance Bio-Collagen Real Deep Mask is a Korean skincare innovation that delivers deep hydration and promotes a radiant complexion. The overnight hydrogel mask features a unique two-part design that allows for a customizable fit, ensuring full facial coverage. Upon application, the mask appears opaque and solidifies into a gel-like texture, gradually becoming transparent as it adheres to the skin overnight. This transformation indicates the absorption of its ingredients, leaving skin feeling plump, smooth and glowing.

“The Bio-Collagen Real Deep Mask has seen explosive sales for two key reasons: (1) its effectiveness, especially for customers who find in-clinic facials costly and time-consuming, this mask delivers comparable results from the comfort of home, and (2) it’s visually satisfying and sensorially fun to use,” says Yura Kim, who leads the U.S. business team at Biodance. “Peeling it off to reveal glowing skin is a joyful moment for many customers,” she added.

Key ingredients: Collagen, Peptides, Ceramides | Quantity: 4 masks per pack

“At Biodance, we never compromise on ingredients; even if it means increasing the cost or delaying a launch, we carefully evaluate every single ingredient and only select the safest and highest-quality options,” Kim exclusively told Post Wanted.

“We even exclude ingredients like PEGs, which are commonly found in many skincare products but can potentially irritate the skin. This level of detail and integrity is what sets our products apart — and why we’ve become a consistent best-seller on Amazon.”

Instead of your usual sheet mask soaked in serum, the Biodance mask is a hydrogel wonder, crafted with marine collagen, peptides and ceramides. It adheres to the skin like a second layer to deliver intense, targeted hydration. Plus, the mask’s peel-off reveal is so satisfying, you’ll be tempted to record it in slo-mo with a dramatic music overlay.

“There might be people who have never tried our Bio-Collagen Real Deep Mask, but almost no one who has only used it once.”

But does it actually work — or is the glow just a temporary TikTok illusion? As someone who has been professionally testing the best in beauty for more than four years, I decided to dive face-first into the hype (literally), put the mask to the test and find out if it’s worth your time, money and #SelfCareSunday slot.

Meet Biodance: the skincare brand that’s all about turning your beauty routine into a joyful celebration for your skin. It’s rooted in London with a splash of Korean skincare magic, mixing smart science with feel-good ingredients that actually deliver.

The secret lies in fermentation. Biodance uses fermented ingredients like bifida and galactomyces that work wonders to strengthen your skin’s natural barrier, tighten pores and leave you with that fresh, radiant glow everyone’s after. No harsh chemicals here; just gentle, effective skincare that’s like a little power boost for your face.

Among its standout products is the Bio-Collagen Real Deep Mask, which has gained significant attention for its ability to hydrate, plump, smooth and brighten the skin overnight. The mask contains ingredients like oligo-hyaluronic acid, ultra-low molecular collagen, galactomyces ferment filtrate and niacinamide, contributing to its effectiveness.

There are more standout products, FYI, but you’ll just have to read on for the 411.

Let me spill the tea on the Biodance Bio-Collagen Real Deep Mask, because this little gem is turning heads for all the right reasons. If your skin’s been feeling dry, tired or just blah, this Korean hydrogel mask might just be your new BFF.

It’s packed with low-molecular-weight fish collagen (fancy, right?), hyaluronic acid, niacinamide and a secret dose of galactomyces ferment filtrate, it’s like a refreshing cocktail for your face that promises to boost hydration and leave your skin looking fresh and oh-so-glowy. Because it’s packed with hyaluronic acid (a key ingredient for hydration) and niacinamide (the best ingredient to balance the skin), this mask is one of the most effective I’ve used.

Start with a clean slate — literally clean skin — and gently press the mask’s two pieces onto your face. I won’t lie, it’s a bit slippery and plays hard to get if you’re a side or stomach sleeper. The brand says you can wear it overnight, but most people stick to 3 or 4 hours until the mask turns translucent (what I did, BTW). Honestly, that’s when the magic happens.

Before using the mask, I applied the Biodance Collagen Mask to Foam Cleanser which we should all be speaking more about. It instantly gave my skin a beautiful glow, which was an excellent precursor for the sheet mask.

In the realm of skincare multitaskers, the Biodance Collagen Mask to Foam Cleanser is a quiet powerhouse that seriously should be talked about more. This dual-action cleanser begins as a thick, mask-like texture that grips onto grime and excess oil, then effortlessly transforms into a creamy foam as you massage it in.

It’s designed to offer a deeper cleanse without the harshness, lifting impurities from clogged pores while still feeling gentle enough for daily use. The formula works hard to refresh, refine and revive dull skin in one elegant step.

To elevate this cleanser, it’s infused with ultra-low molecular collagen (243Da, to be exact), which penetrates deeply to hydrate and subtly firm the skin. Paired with a balanced, mildly acidic pH, it manages to cleanse without disrupting your skin barrier. There’s no tight, squeaky aftermath here. Instead, I was left with skin that felt smooth, plump and wonderfully radiant.

Speaking of magic, the moment I peeled off this mask was a good time. My skin felt like it had just drank a gallon of water. It felt plump, silky smooth and glowing like I just walked off a runway — or at least a really good Instagram filter.

The collagen is there doing its thing, helping to firm up natural fine lines, but don’t expect it to work miracles overnight. Think of it as a serious hydration boost and a glow-up rather than an anti-aging cure-all.

If your skin tends to run on the dry or dull side, this mask is basically a mini spa retreat in a packet. But heads up, my oily or acne-prone friends: proceed with caution due to the overnight period that’s recommended for wear. Luckily, I didn’t experience any breakouts or irritation, but be sure to do a patch test, as always.

After your feel-good mask, I recommend dolloping on the Biodance Collagen Cream. It’s the ultimate soother to finish off your routine on a high note.

The Biodance Collagen Cream is a targeted treatment that helps enhance skin elasticity and refine pores, offering a smoother and more youthful complexion. Its ingredient list includes a potent 243Da ultra-low molecular collagen to address the signs of aging and environmental stressors.

The formulation includes a 70% Mineragen Complex — comprising 59% collagen, 10% mineral water and 1% SYN-COLL — alongside elastin, hyaluronic acid and fibroblasts, which collectively work to fortify the skin’s structure and improve elasticity.

This cream is particularly beneficial for those seeking to minimize the appearance of enlarged pores and enhance skin texture, so it’s wonderful to use following the viral sheet mask, or without it. Its hypoallergenic formula is free from 19 common irritants, making it ideal for sensitive skin like mine.

The Biodance Bio-Collagen Real Deep Mask certainly stands out for its unique use of bio-collagen, which is derived through fermentation and is structurally closer to human collagen than typical hydrolyzed alternatives. This allows for deeper skin penetration and potentially more visible anti-aging results. It focuses heavily on elasticity and hydration, and left my skin noticeably plumper and firmer after use.

Compared to the Dr. Jart+ Vital Hydra Solution Sheet Mask, which prioritizes surface hydration with ingredients like aquaxyl and hyaluronic acid, the Biodance mask offers a more intensive treatment targeting not just moisture, but skin structure and texture. Biodance is also a better value, costing $19 for four masks, whereas Dr. Jart+ is $10 per mask.

In contrast, the 111SKIN Black Diamond Mask — one I love to use for an evening treat — positions itself at the luxury end of the skincare spectrum, using ingredients like NAC Y², black diamond particles and peptides to deliver high-impact results, especially for mature or stressed skin. While the 111SKIN mask provides dramatic firming and radiance, it comes at a significantly higher price point. The Biodance mask serves as a more cost-effective middle ground, delivering some anti-aging and hydrating benefits with high-grade collagen without the premium price tag.

“Biodance is also deeply committed to long-term skin health. We don’t just chase surface-level results; we aim to restore your skin’s natural balance and resilience.”

Yura Kim, leader of the U.S. business team at Biodance

Because of how effective the Biodance Bio-Collagen Real Deep Mask is, I’d recommend using it once every 3-4 weeks. I’d reserve the weekly face mask for a less-intensive sheet mask that feels less like a spa treatment (but still skin-nurturing), like the ESW Beauty Coco Lime Mojito Mocktail Face Mask ($6) or the COSRX Snail Mucin Face Mask ($22 for a 10-pack).

All in all, the Biodance Bio-Collagen Real Deep Mask is a total treat. It’s luxurious, effective and perfect for those days when your skin needs a little extra love. It’s not a miracle worker for aging, but if you want that instant “wow” factor and a splash of hydration, this mask’s got your back. Trust me, your skin will thank you.
