A Biodance mask isn’t a sheet soaked in essence — it’s the essence itself, solidified into a gel, and you wear it for 3–4 hours or overnight, not 20 minutes. If you’ve heard of “that Biodance collagen mask”, it’s the Bio-Collagen Real Deep Mask — the brand’s own word for it is “the all-rounder”. Behind the mask is a personal story: founder Mihwa Kim spent years hosting beauty shows on Korean television; in 2013 she was hit by a car and spent six months at home while her skin recovered. Of everything she tried, it was medical-grade hydrogel that gave her skin its balance back — it worked, but it was impractical for everyday use. Biodance grew out of one question: could a product deliver visible results and still be comfortable enough to use every day? The brand belongs to Beautyselection, a Seoul-based company.
Which Biodance mask to pick
The masks are all called Real Deep Mask; there are five, and each, in the brand’s words, has its own gel and its own job. The easiest place to start is Bio-Collagen: pores, firmness and moisture in one, built around Biodance’s own collagen in very small fragments — 243 Da, as the brand labels it (more in our guide to collagen). Its gel is dense and bouncy, milky white. The other four are chosen by skin concern. Hydro Cera-nol — for sensitive, dry skin with a weakened barrier: ceramides, panthenol and hyaluronic acid, a trio the brand calls Cera-nol (our guide to ceramides explains why skin needs them). Refreshing Sea Kelp — for oily and combination skin prone to shine, breakouts and redness: sea kelp in a light cooling gel, pale green from the seaweed itself; if your skin is breakout-prone, the brand suggests this one rather than the collagen mask. Radiant Vita Niacinamide — for dull skin, uneven tone and dark spots: 2% niacinamide and pineapple water, in a gel that’s pale yellow from the pineapple. Rejuvenating Caviar PDRN — for dryness, signs of ageing and loss of firmness: caviar extract and PDRN (we explain what it is in a separate guide) in a rich, nourishing gel. There are no colourants or fragrance in the masks — the gel’s colour comes from the ingredients themselves.

How to wear a Biodance mask: 3–4 hours or overnight
There are two ways to wear it: overnight, the way the brand intends, or for 3–4 hours during the day. Taking it off after 15–20 minutes, like a sheet mask, means — in the brand’s words — wasting most of its benefit.
In the evening. Cleanse, apply toner and, if you use one, a light serum; skip thick creams and oils before the mask, the brand says — they form a film that slows the gel’s contact with the skin. The mask comes in two pieces: peel off the protective films, place the top half on your forehead with the eye holes lined up with your eyes, the bottom half on your chin and jawline, and smooth from the nose outwards, pressing out any air bubbles. Don’t throw away the little cut-out pieces — put them on your neck or either side of your nose. For a cooler start, chill the pouch in the fridge shortly before use.
Overnight. Wear it until morning: the Real Deep series is made to be worn all night. Each mask is 34 g of gel — a weight the brand settled on so the mask neither dries out nor slips — and, warmed by your skin, it thins over the hours and hugs the face more closely.
In the morning. Take it off once the gel has turned clear — usually by morning, or after 3–4 hours if you wore it during the day: clear means the essence has absorbed, and how quickly that happens depends on your skin temperature and what you’ve put on underneath. Peel it off, pat the remaining essence in with your fingers and don’t rinse; then follow with your usual moisturiser — and sunscreen if it’s daytime. How often: two or three times a week. Don’t put the mask over broken skin or spots you’ve picked; after a peel or laser, wait until your doctor gives the go-ahead.
Not just masks
Biodance makes the same gel in other forms. The gel toner pads are cotton coated in hydrogel on both sides, so only gel touches the skin; there are five, in the same lines as the masks. A pad is the first step after cleansing: sweep it over your face along your skin’s natural lines, avoiding the eyes, and you can also rest it on your nose, cheeks or chin for a few minutes as a mini mask. The difference is simple: pads are for every day, the mask for two or three times a week — exactly how the brand describes the collagen pads: daily maintenance between masks. Pads have their own collection in the shop. There are also eye patches made of the same gel, and the Jelly Serum Mist — hydrogel that starts solid and breaks into fine droplets when sprayed: up close it goes on like a serum, from 10–20 cm away as a light mist. The rest of the range: serums in the same five lines, creams in some of them (the Caviar PDRN capsule cream is gel-based too), cleansers — an oil, a foam and an enzyme cleansing powder — and two toners.
