How it works
Medicube Collagen Glow Booster Serum is a serum built for the treatment step right after toner. Its ingredient list leads with Niacinamide, Adenosine, and Ceramide NP, 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 Collagen Glow Booster 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 Ceramide NP, positioned for barrier support.
- Formulated as a serum for the treatment step right after toner.
- The Korean-market Medicube formula for Collagen Glow Booster 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.
Ceramide NPBarrier support
Ceramide NP sits further down the ingredient list, in a supporting, lower-weighted role. It is an ingredient chosen for barrier support: a lipid that is naturally part of the skin's own barrier, included to support the surface that keeps moisture in and irritants out.
Beta-GlucanComfort and hydration
Beta-Glucan sits further down the ingredient list, in a supporting, lower-weighted role. It is an ingredient chosen for comfort and hydration: a humectant and comfort ingredient derived from oat or yeast sources that helps a formula feel less stripping while it hydrates.
Hydrolyzed CollagenPlumping feel
Hydrolyzed Collagen sits further down the ingredient list, in a supporting, lower-weighted role. It is an ingredient chosen for plumping feel: collagen broken into smaller fragments so it spreads easily and leaves a smoother, more cushioned surface feel.

What does the Collagen Glow Booster 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 Collagen Glow Booster 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 Collagen Glow Booster Serum the same formula sold in Korea, or a US version?
This Collagen Glow Booster 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 Collagen Glow Booster 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 Collagen Glow Booster 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 15ml format. Anyone with a known sensitivity to a specific ingredient should check the full ingredient panel on this page before buying.

How to use
- Use it after toner, morning or evening, before anything heavier goes on over it.
- A small dose is enough from a 15ml bottle, warmed in the palm and pressed over the face.
- Let it settle for a minute, then moisturizer, and sunscreen last in the morning.
- Once or twice a day. Do not use it as your only moisturizer, because a booster is a layer rather than a seal.
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.

Ceramides are part fatty acid and part amino acid and are able to be the grout that keeps the building blocks of the skin together and functioning as a barrier between the inside and outside world.

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.
