Biodance is a Korean skincare brand known for the Bio Collagen Real Deep Mask, an overnight hydrogel mask that turns from white to transparent as it wears. Its range is small and built around that idea: four Real Deep Masks, four matching gel toner pads, a collagen serum and cream, three toners, cleansers and a mineral sunscreen. Start with the collagen mask; add the matching toner pads if you like the format.
Biodance is a mask brand first. One product made it famous, the rest of the range is designed to sit around that product, and the whole catalog fits in one table. This guide explains what the masks are, how the four differ, which pads and creams go with them, and which to buy first. For how overnight collagen masks work in general, including the molecular-weight question, read Korean Collagen Masks: How to Use Them first.
At Daebak, a Seoul-based Korean culture and product company, product descriptions come from Biodance's product pages, and the company facts from the sources listed at the end. We describe what products are marketed for, not what they will do for you. Biodance products in our shop are shipped by the brand.
The brand in brief
Economist Korea reported in April 2026 that Biodance exports to 89 countries and that its Collagen Real Deep Mask had passed 200 million sheets in cumulative sales, roughly four sheets a second by the magazine's arithmetic; the same report describes the product as a hydrogel rather than a cloth sheet mask, whose white gel turns transparent after about three hours on the skin. The Korean trade paper COS'IN reported in July 2025 that the brand, run by Beauty Selection, said its Amazon Prime Day sales rose 56 percent that year, with about 1.5 million Real Deep Masks sold and first place in Amazon's facial mask category during the event. In the US it became a social-media product first: NBC's shopping desk reviewed the Hydro Cera-Nol Real Deep Mask in March 2025 as a mask trending on TikTok and Amazon, and noted the collagen version had already had its own TikTok moment.
On the ingredient: the brand's figure of 243-dalton collagen is its own. A 2020 review in the journal Antioxidants puts native collagen at around 300 kDa, far too large to pass the skin's outer layer, and describes hydrolyzed collagen, broken into fragments of roughly 1 to 10 kDa, as a cosmetic ingredient with good moisturizing properties. Read "firming" and "elasticity" on the box as what the product is marketed for; hydration and a smoother look are what the format reliably delivers.

The four Real Deep Masks
| Mask | Marketed for | Key ingredients, per the brand |
|---|---|---|
| Bio Collagen Real Deep Mask | Hydration, bounce, a smoother look; the original | Collagen extract, niacinamide, galactomyces ferment filtrate, hyaluronic acid |
| Hydro Cera-Nol Real Deep Mask | Dry, barrier-weakened skin | Cera-nol complex, glacial water, panthenol, ceramides, hyaluronic acid |
| Radiant Vita Niacinamide Real Deep Mask | Dullness, uneven tone | 2% niacinamide, 10% pineapple fruit water, glutathione, hyaluronic acid, allantoin |
| Refreshing Sea Kelp Real Deep Mask | Oily, combination and breakout-prone skin | Fermented kelp filtrate, deep sea water |
All four are 34 g hydrogel sheets sold in packs of four. The brand's instructions are the same for each: after cleansing and your usual toner or serum, remove the protective films, press the mask on, and leave it for three to four hours or overnight until the sheet has gone transparent, then pat in what is left. A sheet mask is a twenty-minute product; these are not, and that is the whole point of the format.
The rest of the range
| Group | Marketed for | Products |
|---|---|---|
| Gel toner pads | A daily, pad-format version of each mask | Collagen Gel Toner Pads, Cera-Nol Gel Toner Pads, Vita Niacinamide Gel Toner Pads, Sea Kelp Gel Toner Pads |
| Collagen peptide | Pores and firmness, as the brand positions it | Pore Perfecting Collagen Peptide Serum, Pore Perfecting Collagen Peptide Cream |
| Toners | The first layer after cleansing | First Synergy Toner, Micro Dual Serum Toner (97 percent serum water, 3 percent grape seed oil), Skin Refining Mild PHA Toner (8 percent PHA) |
| Skin Glow | Hydration and a dewy finish | Skin Glow Essence Cream, Skin Glow Vital Ampoule, Skin Glow Tone Up Booster SPF50+ |
| Cleansing | First and second cleanse | Collagen Cleansing Oil, Collagen Mask to Foam Cleanser, Hydro Ceramide Cleansing Powder |
| Sun and base | Mineral SPF; a makeup base | Skin Barrier Sun Safe SPF50+ PA++++, Skin All-day Cover Balm |
Which product first
- Bio Collagen Real Deep Mask. The original, and the one to judge the brand by. Use it once or twice a week, overnight, on a night when you are not using a strong active. If your skin is dry and tight, start with the Hydro Cera-Nol version instead; if it is oily, the Sea Kelp version.
- The matching gel toner pads. The Collagen Gel Toner Pads carry the same collagen-water idea into a daily step, cooling and essence-soaked; how toner pads fit a routine is in Korean Toner Pads. Each mask has a pad to match.
- Pore Perfecting Collagen Peptide Cream. The brand's everyday moisturizer, described as makeup-ready and non-sticky, with its collagen water and a ten-peptide complex. The serum is the lighter layer underneath it.
- A cleanser, if you want the full set. The Collagen Mask to Foam Cleanser doubles as a short wash-off pore mask; the Hydro Ceramide Cleansing Powder is a single-use enzyme powder for travel.

A routine by skin type
| Skin | Daily | One or two nights a week |
|---|---|---|
| Dry | Collagen Cleansing Oil at night, First Synergy Toner, Cera-Nol Gel Toner Pads, Skin Glow Vital Ampoule, Skin Glow Essence Cream, Skin Barrier Sun Safe in the morning | Hydro Cera-Nol Real Deep Mask overnight |
| Normal or combination | Mask to Foam Cleanser, Micro Dual Serum Toner, Collagen Gel Toner Pads, Collagen Peptide Serum, Collagen Peptide Cream, sunscreen | Bio Collagen Real Deep Mask overnight |
| Oily or breakout-prone | Mask to Foam Cleanser, Skin Refining Mild PHA Toner, Sea Kelp Gel Toner Pads, Collagen Peptide Serum, sunscreen | Refreshing Sea Kelp Real Deep Mask overnight |
| Dull or uneven tone | Mask to Foam Cleanser, First Synergy Toner, Vita Niacinamide Gel Toner Pads, Collagen Peptide Cream, Skin Glow Tone Up Booster | Radiant Vita Niacinamide Real Deep Mask overnight |
Two practical points. The masks are the brand's reason to exist; if you only ever buy one Biodance product, buy a mask and use the rest of your routine from another brand. And the PHA toner is a mild exfoliant: use it in the evening and not on the same night as a strong acid or retinol; the acid families are explained in AHA, BHA and PHA Toners Explained.

How Biodance compares
Overnight hydrogel masks are now a category, not a product: COSRX sells a snail-mucin version and Round Lab a camellia-collagen version, both in our COSRX guide and Round Lab guide. Biodance's difference is focus: it has four masks, four matching pads and little else, where the bigger brands treat the mask as one line among many. If you want to compare the masks side by side, Korean Collagen Masks does that; the wider brand map is in Best K-Beauty Brands.
Brand products in our shop are shipped by the brands. If you would rather try a set of Korean skincare chosen for you each season, the Daebak K-Beauty Box is a separate, curated option.
FAQ
What is Biodance known for?
The Bio Collagen Real Deep Mask, an overnight hydrogel mask that turns transparent as it wears. Economist Korea reported in April 2026 that the mask had passed 200 million sheets sold and that the brand exports to 89 countries.
How long do you leave a Biodance mask on?
Three to four hours or overnight, per the brand, until the sheet has turned transparent. Remove it and pat in what remains.
Which Biodance mask is right for my skin?
Bio Collagen for most skin; Hydro Cera-Nol for dry or barrier-weakened skin; Radiant Vita Niacinamide for dullness; Refreshing Sea Kelp for oily or breakout-prone skin.
Does the collagen in the mask go into the skin?
Collagen applied to the skin does not become the skin's own collagen. A 2020 review in Antioxidants explains that native collagen is far too large to pass the outer skin layer, which is why brands use hydrolyzed, low-molecular collagen as a moisturizing ingredient. Treat firming claims as the brand's positioning.
Is Biodance a Korean brand?
Yes. COS'IN reports it is operated by Beauty Selection, a Korean company, and Economist Korea reports exports to 89 countries. Our shop lists the brand's products shipped by the brand.
