How it works
Medicube Rosemary PDRN Scalp Serum 20ml is a scalp serum built for a leave-in scalp step used a few times a week. Its ingredient list leads with Caffeine, Allantoin, and Panthenol, 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. Caffeine does the most work here as a de-puffing look, and the remaining actives round out the texture and finish rather than compete for attention. Placed as a leave-in scalp step used a few times a week, it is meant to be used AM or PM rather than swapped freely between steps. Because this is the Korean-market version of the Rosemary PDRN Scalp Serum 20ml line rather than a US-reformulated variant, the texture and finish match what Medicube sells through Korean retail.

Key actives
CaffeineDe-puffing look
Caffeine sits near the top of the ingredient list, where the formula puts its heaviest-weighted ingredients. It is an ingredient chosen for de-puffing look: an ingredient chosen for its cooling, tightening feel on the skin's surface, most often used around the eye area for a fresher-looking finish.
AllantoinComfort
Allantoin sits near the top of the ingredient list, where the formula puts its heaviest-weighted ingredients. It is an ingredient chosen for comfort: a comfort ingredient with a long safety record, added to keep the finish gentle on skin that is dealing with dryness or mild sensitivity.
PanthenolComfort
Panthenol sits near the top of the ingredient list, where the formula puts its heaviest-weighted ingredients. It is an ingredient chosen for comfort: provitamin B5, a humectant and comfort ingredient that softens the finish and helps a formula feel less drying over repeated use.
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.
NiacinamideTone and texture
Niacinamide sits in the middle stretch of the ingredient list, a supporting rather than a headline role. 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.
What does the Rosemary PDRN Scalp Serum 20ml actually contain?
Its ingredient list is led by Caffeine, 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 Rosemary PDRN Scalp Serum 20ml?
Use this scalp serum as a leave-in scalp step used a few times a week. To apply, part the hair in sections and apply drop by drop directly to the scalp, massaging in with fingertips. Keep it to AM or 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 Rosemary PDRN Scalp Serum 20ml the same formula sold in Korea, or a US version?
This Rosemary PDRN Scalp Serum 20ml 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 Rosemary PDRN Scalp Serum 20ml with other actives in my routine?
Yes, as long as it is used in its own step, a leave-in scalp step used a few times a week, 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 Rosemary PDRN Scalp Serum 20ml suited for?
It suits most skin types looking for leave-in scalp step used few times week rather than a single acute problem. It comes in a 20ml format. Anyone with a known sensitivity to a specific ingredient should check the full ingredient panel on this page before buying.

It has also been proven that caffeine stimulates lipolysis, which Lupo et al postulated may contribute to improvements in lower eyelid sagging and puffiness.
