COSRX - 5 PDRN Hyaluronic Acid Vital Hydrating Hydrogel Mask 34g x 3ea

COSRX 5 PDRN Hyaluronic Acid Vital Hydrating Hydrogel Mask combines five types of PDRN with eight hyaluronic acids — a hydrogel mask that turns transparent as it delivers.

It turns clear as it works

The hydrogel starts opaque and becomes transparent through the treatment. It’s a visual cue rather than a mechanism, but a genuinely useful one — you can see when the mask has given what it has.

Five types of PDRN

Salmon alongside plant and microbial sources. PDRN is the defining Korean skincare ingredient of 2026, and multi-source formulas are how brands are differentiating within it.

Eight types of hyaluronic acid

Larger molecules hold water at the surface, smaller ones spread through the upper layers. Eight covers considerably more ground than one — which matters in a mask, where the whole point is saturation.

Hydrogel over fabric

Hydrogel clings more closely to facial curves, feels cooler on contact and holds moisture longer before drying out. For a hydrating mask, that extra time is the whole advantage.

For skin that looks tired and dull

After a short night, a flight, or a stretch of stress. This is a reset rather than a routine step — which is what three masks in a pack is designed around.

Frequently asked questions

How long should I leave it on?

Fifteen to twenty minutes. Remove before it dries out completely — a drying mask starts drawing moisture back out of the skin.

Do I rinse afterwards?

No — pat the remaining essence in and follow with moisturizer. Rinsing washes away the part you paid for.

Should I chill it?

A chilled hydrogel mask on hot skin is genuinely comforting. Gradual cooling suits skin far better than direct ice.

Is this vegan?

No — one of the five PDRN sources is salmon.

How often can I use one?

Two or three times a week, or whenever skin needs more than your routine gives it.
