How it works
Medicube PDRN Pink Collagen Bubble Serum is a serum built for the treatment step right after toner. Its ingredient list leads with Niacinamide, Adenosine, and Collagen, so the formula's stated purpose lines up with what actually sits near the top of that list rather than with a single marketing ingredient buried further down. Niacinamide does the most work here as a tone and texture, and the remaining actives round out the texture and finish rather than compete for attention. Placed as the treatment step right after toner, it is meant to be used AM/PM rather than swapped freely between steps. Because this is the Korean-market version of the PDRN Pink Collagen Bubble Serum line rather than a US-reformulated variant, the texture and finish match what Medicube sells through Korean retail.
Key benefits
- Built around Niacinamide, positioned for tone and texture.
- Built around Adenosine, positioned for firming look.
- Built around Collagen, positioned for plumping feel.
- Formulated as a serum for the treatment step right after toner.
- The Korean-market Medicube formula for PDRN Pink Collagen Bubble Serum, matching what Medicube sells in Korea rather than a US-reformulated line.
Key actives
NiacinamideTone and texture
Niacinamide sits near the top of the ingredient list, where the formula puts its heaviest-weighted ingredients. It is an ingredient chosen for tone and texture: a form of vitamin B3 that supports a more even-looking tone and a smoother surface texture with regular use, and layers comfortably under most other actives.
AdenosineFirming look
Adenosine sits in the middle stretch of the ingredient list, a supporting rather than a headline role. It is an ingredient chosen for firming look: a nucleoside included for its reputation in smoothing the look of fine expression lines, one of the more established anti-aging ingredients in Korean formulation.
CollagenPlumping feel
Collagen sits in the middle stretch of the ingredient list, a supporting rather than a headline role. It is an ingredient chosen for plumping feel: included for the cushioned, bouncy surface feel it gives a formula rather than for any claim about the skin's own collagen.
Sodium DNARegeneration support
Sodium DNA sits in the middle stretch of the ingredient list, a supporting rather than a headline role. It is an ingredient chosen for regeneration support: a salmon-derived DNA fragment ingredient that has become one of the signature actives in recent Korean formulation, chosen for its reputation supporting a plumper, more resilient-looking surface.
RetinolRenewal
Retinol sits further down the ingredient list, in a supporting, lower-weighted role. It is an ingredient chosen for renewal: a vitamin A derivative and one of the best studied ingredients in skincare, included here at a level meant for nightly use rather than an occasional strong peel.

What does the PDRN Pink Collagen Bubble Serum actually contain?
Its ingredient list is led by Niacinamide, with the rest of the formula built to support that active rather than compete with it. We list the ingredients in the order the manufacturer prints them, so the ones near the top of the panel are doing the most work in the formula.
How do I use the PDRN Pink Collagen Bubble Serum?
Use this serum as the treatment step right after toner. To apply, smooth or press onto cleansed, toned skin and follow with moisturizer. Keep it to AM/PM unless the packaging states otherwise, and give the rest of the routine a moment to settle before layering the next step. Give it a full bottle or box before judging the result, since most Korean routines are built for steady use rather than a single application.
Is the PDRN Pink Collagen Bubble Serum the same formula sold in Korea, or a US version?
This PDRN Pink Collagen Bubble Serum is the Korean-market formula, not a version reformulated for US shelves. It arrives with its original Korean-market barcode and batch code intact so the formula can be checked against the box on arrival.
Can I use the PDRN Pink Collagen Bubble Serum with other actives in my routine?
Yes, as long as it is used in its own step, the treatment step right after toner, and not layered on top of a product doing the same job. Introduce any new step gradually over the first week or two and keep an eye on how the skin responds before adding a second new active alongside it.
Who is the PDRN Pink Collagen Bubble Serum suited for?
It suits most skin types looking for treatment step right after toner rather than a single acute problem. It comes in a 95ml format. Anyone with a known sensitivity to a specific ingredient should check the full ingredient panel on this page before buying.

Payment and security
We accept
How to use
- Use it after toner in the serum slot, morning or evening, on skin that is still slightly damp.
- A pump into the palm, where it foams, then pressed over the face before the foam has collapsed.
- Wait for it to settle into a thin layer, then moisturizer, then sunscreen in the morning.
- Once or twice a day. Do not rub the foam in as though it were a cleanser, because this one stays on.
Worth knowing
- Patch test on the inner arm before the first full-face application, especially on skin that reacts easily to new products.
- Stop use and rinse off if stinging, burning, or new redness shows up rather than pushing through discomfort.
