The Biodance Bio-Collagen Real Deep Mask is a hydrogel you wear at least 3 hours or overnight, and it turns transparent when it is finished.
That is what separates it from a regular sheet mask, which is designed for a short session and starts to dry out as its essence evaporates.
This post covers how to use it, the per-mask price, what is inside, and who it suits.

biodance bio-collagen mask overnight: what changes when you sleep in it
If your sheet mask dries out before you get anything from it, an overnight hydrogel is worth trying — the Biodance Bio-Collagen Real Deep Mask is built for exactly that.
The gel does not evaporate, so it can stay on for 3 hours or through the night, and the brand states it passed an 8-hour wear test.
That number is the brand’s own; who ran the test and what was measured is not published, so treat it as a brand claim.
The question is live right now: an r/AsianBeauty thread titled ‘Are overnight wrapping masks actually worth it?’ was posted on September 14, 2026.
On the retail side, a GlowOlive sale report found the mask held the #4–6 spot in Olive Young’s sheet-mask category through the entire autumn 2026 sale.
This is the mask people are actually asking about, not a theoretical pick.
If your current sheet masks feel dry within 20 minutes, this format solves that specific problem.
If you only wear masks for a short session anyway, the difference matters less.
| Sale price | 19,000 KRW (1,000 KRW off, 5% off list) |
|---|---|
| List price | 20,000 KRW |
| Per mask at sale price | 19,000 / 4 = 4,750 KRW |
| Per mask at list | 20,000 / 4 = 5,000 KRW |
| Size | 34 g (1.19 fl.oz) per mask, 4 masks per pack |
How to use it (and when to take it off)
The official sequence is simple, and the removal signal is built into the mask itself.
Per the official Biodance product page, the order is:
- Cleanse and finish your entire base skincare routine.
- Remove the film from the mask and apply it to your face.
- Leave it on at least 3 hours, or wear it overnight as a sleeping pack.
- Take it off once the mask turns transparent — the color change is the signal that the ingredients have been delivered.
The gel starts opaque and goes clear as it releases its contents, so you do not need a timer.
The official tip is to use it as the last step of your routine, like a sleeping pack.
There is no official per-week limit stated on the product page, so the cadence is yours to decide — any fixed ‘use it X times a week’ schedule would be made up.

Price: 4-pack vs the 7+1 bundle
| Format | Price | Per mask |
|---|---|---|
| 4-pack, sale | 19,000 KRW | about 4,750 KRW |
| 4-pack, list | 20,000 KRW | 5,000 KRW |
| 7+1 bundle (7 packs + 1 free) | not confirmed on a first-party page | — |
The discount is 1,000 KRW off, which works out to 5% off list.
A 7+1 bundle (7 packs plus 1 free) exists as the value format and appears in sale-report coverage, but no confirmed KRW price was found on a first-party page.
Until a price shows up on an official page, the only usable numbers are the 4-pack’s.
Whether the 19,000 KRW price holds after the Olive Young sale window is also not confirmed, so check the store price on the day you buy.
If I were buying today, I would take the 4-pack at 19,000 KRW and skip hunting for the bundle — 4,750 KRW per mask is a known number, and the bundle’s is not.
55,000ppb collagen, three ferments, and no PEG for sensitive skin
The headline ingredient is collagen extract at 55,000 ppb, alongside galactomyces ferment filtrate, niacinamide, hydrolyzed hyaluronic acid, adenosine, and tocopherol.
The product is certified in Korea as a functional cosmetic for both brightening and wrinkle improvement.
The ingredient list also includes Bifida and Lactobacillus ferments plus betaine, allantoin, and panthenol-class soothing agents.
Biodance positions the formula as free of PEG-series and common allergy-causing ingredients, so it is aimed at sensitive skin.
That is the brand’s own positioning.
The full ingredient list contains botanical extracts, so a patch test first is the sensible move if your skin reacts easily.
If you specifically avoid fragrance-adjacent formulas, read the full ingredient list on the product page before ordering — the certification covers brightening and wrinkles, not tolerance for every skin type.
Overnight hydrogel vs a regular sheet mask
The core difference is drying: a hydrogel does not evaporate, and a dry sheet mask does.
That single property is what makes multi-hour and overnight wear possible with one and not the other.
Hydrogel was originally developed as a medical material for wound healing, and on the skin it gives a cool, jelly-like touch that the brand cites as a further difference.
| Overnight hydrogel (this mask) | Regular dry sheet mask | |
|---|---|---|
| Drying out | Does not evaporate or dry out | Evaporates and dries out |
| Wear time | 3+ hours or overnight; brand states an 8-hour wear test passed | Short-session format (about 20 minutes is the common pattern) |
| Feel on application | Cool, jelly-like touch | Wet fabric |
| Cost per use here | 4,750 KRW at the sale price | Varies by brand |
One caution on the comparison: a verified per-mask weight for a typical essence-type sheet mask was not found in the sources, so the table sticks to format behavior rather than essence amounts.
If you want a mask that works while you sleep, the hydrogel is the format built for it.
If you want a quick pre-makeup step, a basic sheet still does that job for less per use.

Who should buy it — and what is still unconfirmed
This format suits you if you want an actual overnight mask rather than a 20-minute sheet, and the brand markets the series as having 165 million masks sold cumulatively.
The manufacturer is Icure Co., the seller is Beauty Selection Co., it is made in Korea, and the shelf life is 36 months from manufacture.
It is marketed as suitable for all skin types.
Several things could not be verified as of September 15, 2026: the 7+1 bundle’s KRW price, overseas pricing on Amazon or YesStyle, whether the 19,000 KRW sale price holds after the sale, and independent (non-brand) evidence for the 8-hour wear claim.
None of those numbers should be treated as known until they appear on a first-party page.
Precautions from the product page: avoid the eye area and broken skin, discontinue and consult a doctor on redness, swelling, or itching, and store it away from direct sunlight and children.
