A gel mask, built around three actives
PDRN, hydrolyzed collagen, and niacinamide — chosen to work together, not against each other.
What is PDRN (Sodium DNA)?
PDRN is a polynucleotide derived from salmon DNA, prized in Korean skincare for helping skin look firmer, plumper, and more elastic over time.
Why hydrolyzed collagen?
Hydrolyzed collagen is broken into smaller molecules so it can sit on the skin surface and draw water in, leaving skin softer, smoother, and visibly bouncier.
Why a hydrogel mask?
Our two-piece gel sheet hugs every contour and slowly releases actives over 1–2 hours, so each drop is absorbed instead of evaporating like a paper sheet.
Niacinamide, gently dosed.
A low, well-tolerated dose of niacinamide supports an even tone and a quiet, glassy finish — no fragrance, no harsh acids, no sting.
PDRN Pink Collagen Gel Mask
A two-piece hydrogel sheet that contours to your face and releases actives slowly. It starts pink, turns transparent — a quiet signal your skin has fully absorbed every drop.
- PDRN — Sodium DNA for elasticity
- Hydrolyzed Collagen — for bounce
- Niacinamide — for a glassy, even tone
Five quiet steps
Apply on dry skin and stay still — or lie down for the first few minutes — to help the gel set in place.
- 01
Cleanse & tone
Then pat skin completely dry so the gel can grip evenly.
- 02
Apply lower, then upper
Place the lower hydrogel piece first, then the upper. The two halves cover every contour.
- 03
Press out air bubbles
Smooth gently from the center outward so the gel sits flush against the skin.
- 04
Wait 1–2 hours
The mask starts pink and turns clear as the actives fully absorb.
- 05
Remove & enjoy the glow
Pat any remaining essence in. No rinse needed.
It turns clear when it's done
The gel starts a soft pink. After 1–2 hours it turns transparent — your visible cue the active ingredients have fully absorbed into the skin.
