How it works
Medicube AGE-R Booster Gel is a conductor gel built for a step used with an at-home skincare device. Its ingredient list leads with Niacinamide, Sodium Hyaluronate, and Soluble 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 a step used with an at-home skincare device, it is meant to be used AM/PM rather than swapped freely between steps. Because this is the Korean-market version of the AGE-R Booster Gel line rather than a US-reformulated variant, the texture and finish match what Medicube sells through Korean retail.

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.
Sodium HyaluronateHydration
Sodium Hyaluronate sits near the top of the ingredient list, where the formula puts its heaviest-weighted ingredients. It is an ingredient chosen for hydration: a salt form of hyaluronic acid that draws and holds water at the skin's surface, leaving the finish plumper and less tight within minutes of use.
Soluble CollagenPlumping feel
Soluble Collagen sits near the top of the ingredient list, where the formula puts its heaviest-weighted ingredients. It is an ingredient chosen for plumping feel: a water-soluble collagen fragment that sits on the skin's surface and gives an immediate plumping, cushioned feel without any claim about the skin's own collagen underneath.
CollagenPlumping feel
Collagen sits near the top of the ingredient list, where the formula puts its heaviest-weighted ingredients. 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.
Hydrolyzed Hyaluronic AcidHydration
Hydrolyzed Hyaluronic Acid sits in the middle stretch of the ingredient list, a supporting rather than a headline role. It is an ingredient chosen for hydration: a lower molecular weight form of hyaluronic acid that spreads more easily across the surface and layers well under other water-based steps.

What does the AGE-R Booster Gel 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 AGE-R Booster Gel?
Use this conductor gel as a step used with an at-home skincare device. To apply, spread a generous layer over the treatment area before running the device head over it. 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 AGE-R Booster Gel the same formula sold in Korea, or a US version?
This AGE-R Booster Gel 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 AGE-R Booster Gel with other actives in my routine?
Yes, as long as it is used in its own step, a step used with an at-home skincare device, 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 AGE-R Booster Gel suited for?
It suits most skin types looking for step used with an at-home skincare device rather than a single acute problem. It comes in a 100ml 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 the AGE-R Booster Gel after toner and before moisturizer, morning and evening.
- Three or four drops covers the whole face. Press it in with flat palms instead of rubbing it around.
- Toner first so the surface is damp, then this, then about a minute before your moisturizer goes over the top.
- Twice a day, every day. Do not stack it with a second serum of the same kind; two hydrating serums in one routine do the work of one.
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.

Hyaluronic acid helps bind water to collagen, which traps water in the skin. That helps make the skin more plump and full-looking.

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.
