How it works
A hydrogel sheet is a delivery format rather than a formula type: the essence is set into a gel sheet so it stays against the face instead of evaporating off it. This is the hydrating mask in COSRX's 5 PDRN line, and it goes on after toner, in place of a serum step, in the evening. Sheet on, wait the time the pack gives, sheet off, then press in what is left rather than rinsing it away. Skin that looks flat and dry at the end of a long day is what a mask like this is for. Two or three evenings a week is a normal rhythm, as an addition to a routine rather than a replacement for one.
Key benefits
- Eight hyaluronate forms on the list, from hydrolyzed fragments to a crosspolymer, hydrate at layered depths
- Both sodium DNA and hydrolyzed DNA appear, the two DNA-derived ingredients behind the PDRN name
- Niacinamide sits fourth on the list for a fresher, more even look
- Centella asiatica extract and coptis japonica root extract carry the calming half of the formula
- The sheet turns visibly transparent as it warms against skin, a real cue that it has settled in
- Sold as three individually wrapped sheets, sized for one use each

COSRX 5 PDRN Hyaluronic Acid Vital Hydrating Hydrogel Mask
What does PDRN mean on this hydrogel mask's ingredient list?
PDRN is not a single named ingredient on Korean labels; it shows up here as Sodium DNA and, further down the list, Hydrolyzed DNA, the two DNA-derived materials the marketing name refers to. Both sit alongside adenosine and niacinamide, which is fourth on the list. Reading the box by its actual INCI names rather than the marketing shorthand is the only way to know what a PDRN product truly contains.
How many forms of hyaluronic acid are actually in this mask?
Eight separate hyaluronate entries run through the list: sodium hyaluronate, hydrolyzed hyaluronic acid, hydrolyzed sodium hyaluronate, hyaluronic acid itself, potassium hyaluronate, sodium hyaluronate crosspolymer, hydroxypropyltrimonium hyaluronate, and sodium acetylated hyaluronate. Each form differs in molecular weight and how it sits on or in the skin, which is why formulators layer several rather than relying on one.
Is this mask meant for daily use?
The mask is a sheet-format hydrogel meant for occasional, concentrated use rather than a daily step, since it is packaged and sold as individually wrapped sheets rather than a pump or jar. Leave it on until the gel turns visibly transparent against the skin, then pat in whatever is left. A few times a week is a reasonable starting cadence for most skin.
Does this mask contain fragrance or added scent?
No parfum or fragrance appears anywhere on the ingredient list. The formula instead relies on the base hydrogel matrix, carob gum and agar among them, to carry the actives without a scent layered on top, which matters for anyone reacting to added fragrance in leave-on products.
What is niacinamide doing in a hydrating mask like this one?
Niacinamide sits fourth on the list, ahead of every hyaluronate form and the PDRN complex, a high position rather than a token afterthought. Niacinamide is widely used for a fresher, more even-looking complexion alongside its hydrating packmates here, and its high list position is a real formulation signal rather than a marketing claim.

How to use
- Use the 5 PDRN Hyaluronic Acid Vital Hydrating Hydrogel Mask after toner, in place of your serum step, in the evening.
- Unfold the sheet, line it up at the eyes first, then smooth it outward so no air is trapped underneath.
- Take it off at the time printed on the pack, pat in the essence left behind, then go straight to your moisturizer.
- Two or three evenings a week. Do not leave it on past its time; a sheet that has gone dry takes moisture back off the face as it goes.
Worth knowing
- Collagen here is not plant-derived, so this is not a vegan formula.

What skin-care professionals say about the key actives in this formula, quoted from the medical sources linked beside each.
Hyaluronic acid helps bind water to collagen, which traps water in the skin. That helps make the skin more plump and full-looking.

Niacinamide helps reduce the appearance of pores in a few ways. By strengthening the skin barrier and improving elasticity, pores appear less noticeable and more even.
