How it works
Medicube Deoxyribose Scalp Serum is a scalp serum built for a leave-in scalp step used a few times a week. Its ingredient list leads with Melaleuca Alternifolia (Tea Tree) Leaf Oil, Rosmarinus Officinalis (Rosemary) Leaf Oil, and Niacinamide, 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. Melaleuca Alternifolia (Tea Tree) Leaf Oil does the most work here as a clarity, 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 Deoxyribose Scalp Serum line rather than a US-reformulated variant, the texture and finish match what Medicube sells through Korean retail.

Key actives
Melaleuca Alternifolia (Tea Tree) Leaf OilClarity
Melaleuca Alternifolia (Tea Tree) Leaf Oil sits in the middle stretch of the ingredient list, a supporting rather than a headline role. It is an ingredient chosen for clarity: a botanical long used in blemish-prone routines for its fresh, clean feel on the skin's surface.
Rosmarinus Officinalis (Rosemary) Leaf OilScalp comfort
Rosmarinus Officinalis (Rosemary) Leaf Oil sits in the middle stretch of the ingredient list, a supporting rather than a headline role. It is an ingredient chosen for scalp comfort: a botanical extract with a long folk reputation for scalp health, included here to support a calmer, more comfortable-feeling scalp.
NiacinamideTone and texture
Niacinamide sits further down the ingredient list, in a supporting, lower-weighted 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.
Hexapeptide-2Firming look
Hexapeptide-2 sits further down the ingredient list, in a supporting, lower-weighted role. It is an ingredient chosen for firming look: a signal peptide included for its reputation supporting the look of firmer, more resilient skin over consistent use.
CaffeineDe-puffing look
Caffeine sits further down the ingredient list, in a supporting, lower-weighted role. 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.
Medicube Deoxyribose Scalp Serum
What does the Deoxyribose Scalp Serum actually contain?
Its ingredient list is led by Melaleuca Alternifolia (Tea Tree) Leaf Oil, 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 Deoxyribose Scalp Serum?
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 Deoxyribose Scalp Serum the same formula sold in Korea, or a US version?
This Deoxyribose Scalp 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 Deoxyribose Scalp Serum 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 Deoxyribose Scalp Serum 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.

Payment and security
We accept
How to use
- Use it at night on a dry scalp, parting the hair in sections so the nozzle reaches skin rather than hair.
- A few drops per section, worked in with the fingertips for a moment, then left in.
- It goes on a dry head rather than a wet one, and nothing needs to go over it.
- Nightly or every other night. Do not rinse it out, and do not use it in place of washing the scalp.
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.

If you increase blood flow to the scalp, you give your hair the nutrients it needs to shed less, grow more and just be a bit healthier.
Shilpi Khetarpal, MDDermatologist, Cleveland Clinic I think it's fair to say I've seen lots of patients use tea tree oil for a variety of skin issues. It's a natural remedy that is known to help.

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.
