Short verdict: the best serum to use with Medicube Booster Pro is a simple hydrating serum that gives the device enough slip without irritating your skin. My safest pick is Torriden DIVE-IN Serum for lightweight hydration. Use COSRX Snail Mucin 96 if you want a thicker, bouncier layer, and Skin1004 Centella Ampoule if your skin is easily annoyed. I would not use strong acids, retinoids, or spicy vitamin C as my first device-night serum.
This is the question people ask after buying a Medicube device: "Okay, cute, but what do I put under it?" Very fair. A device without the right skincare layer can feel draggy, sticky, or way too intense. The serum is not just decoration. It changes how the routine feels.
I tested the regular Medicube Age-R Booster Pro for four weeks, and the biggest difference was not a dramatic new face. It was product behavior. Hydrating serums felt less like they were sitting on top, my skin looked more polished the next morning, and makeup prep was smoother. That only worked because I kept the product layer boring in the best way.

So this is my practical guide to the best serums to pair with Medicube Booster Pro, Booster Pro X2, and Mini Booster Pro. Not every serum belongs under a device. Some should stay on non-device nights where they can mind their business.
Quick Answer: Best Serum for Medicube Device Nights
| Best overall | Torriden DIVE-IN Serum |
| Best cushiony layer | COSRX Snail Mucin 96 |
| Best calming layer | Skin1004 Centella Ampoule |
| Use separately | Beauty of Joseon Glow Serum |
| Avoid at first | Strong acids, retinoids, harsh vitamin C, peeling pads |
What Kind of Serum Works Best With Medicube Booster Pro?
For device nights, I want three things from a serum:
- Enough slip so the device glides without dragging.
- Simple hydration or calming support.
- Low irritation risk, especially when you are still learning the device.
That means watery hydrating serums, snail mucin-style essences, and calming centella ampoules make the most sense. They support the device routine without turning the night into an irritation experiment.
What I do not want: exfoliating acids, strong retinoids, intense vitamin C, peeling pads, or anything that already makes your skin tingle. That does not mean those products are bad. It means they are not the first thing I would put under an electrical beauty device.
Device night is not the night to prove your skin is brave. Your skin did not sign up for that.
1. Torriden DIVE-IN Serum: Best Overall Serum for Medicube Booster Pro
If I had to choose one serum to pair with Medicube Booster Pro, I would start with Torriden DIVE-IN Serum.
It is lightweight, watery, and easy to spread. That matters because a device routine becomes annoying fast if the serum is too thick, too sticky, or pills under the next layer. Torriden gives the skin enough hydration without making the whole routine feel like you applied a gel mask by accident.
In my full Torriden DIVE-IN Serum review, I liked it most because it disappeared into the skin quickly and played well under sunscreen and makeup. That same quality is why I like it for device nights. It is not dramatic. It is useful.
Use Torriden if:
- You want the safest first serum for Booster mode.
- Your skin gets dehydrated but hates heavy textures.
- You want something that layers easily under moisturizer.
- You use your device before makeup-prep days.
My routine would be: cleanse, toner or mist if you use one, Torriden DIVE-IN, Medicube Booster Pro on a low setting, moisturizer. Keep it boring. Boring is underrated when your face is involved.

2. COSRX Snail Mucin 96: Best Cushiony Serum Layer
COSRX Snail Mucin 96 is the pick if you want a more cushiony layer under your device. It is thicker and more elastic than Torriden, so it gives a different glide feel.
I like snail mucin for nights when my skin feels a little dry, tight, or generally dramatic. It can make the routine feel softer because the texture has more bounce. If Torriden is the invisible hydration layer, COSRX is the plush one.
In my COSRX Snail Mucin 96 review, I treated it as a hydration and repair-style essence, not a miracle product. That is still how I would use it with Medicube. It is good when you want a comfortable layer, especially before moisturizer.
Use COSRX Snail Mucin if:
- Your skin feels dry or tight after cleansing.
- You want more cushion than a watery serum gives.
- You like a bouncy essence texture.
- You are not bothered by snail mucin's stringy feel.
One note: use enough product so the device glides, but do not drown your face. Too much snail mucin can feel sticky. If the device is slipping everywhere, you used more enthusiasm than product strategy.

3. Skin1004 Centella Ampoule: Best Calming Option
If your skin gets reactive easily, Skin1004 Madagascar Centella Ampoule is the calming lane.
This is not the serum I would choose for maximum slip or bouncy texture. It is thinner and more watery. I would choose it when the point of the routine is keeping the skin calm and simple.
In my Skin1004 Centella Ampoule review, I positioned it as a soothing, barrier-friendly product. That is exactly why it belongs in this guide. If your skin is easily red, easily annoyed, or nervous around new routines, centella is the safer personality.
Use Skin1004 if:
- Your skin is sensitive or easily flushed.
- You want a very simple calming layer.
- You are using the device at the lowest setting first.
- You plan to follow with a moisturizer that gives the cushion.
I would not rely on this alone if your device needs a lot of glide. Pair it with a moisturizer after, or use it on a non-device calming night. For Medicube nights, it works best when your skin wants calm more than slip.

4. Beauty of Joseon Glow Serum: Good Serum, Not My First Device-Night Pick
Beauty of Joseon Glow Serum is a good brightening serum, but I would not make it my first serum under Medicube Booster Pro.
Why? Because device nights are where I prefer hydration and calm. BOJ Glow Serum is more of a brightening, propolis-and-niacinamide type of serum. That can be useful in a routine, but I would separate it from the first few device sessions until I know my skin is calm.
In my Beauty of Joseon Glow Serum review, I liked it for dullness and tone. I still like it. I would just use it on a morning routine or a non-device night, then use Torriden, COSRX, or Skin1004 when the device comes out.
Use BOJ Glow Serum if:
- You want brightening support in your weekly routine.
- Your skin already tolerates niacinamide well.
- You are not stacking it with too many other actives.
- You use it away from your first few device nights.
This is the difference between "good product" and "right product for this step." Those are not always the same thing.

Serums I Would Avoid With Medicube at First
I would avoid these under Medicube device sessions until your skin is very comfortable with the device:
- Retinol or retinal serums.
- AHA, BHA, or PHA exfoliating serums.
- Peeling pads.
- Strong vitamin C formulas that sting.
- Any serum that already makes your skin flush or tingle.
Again, this does not mean those products are bad. It means they deserve their own night. Stacking active irritation plus a device is where people turn a reasonable routine into a skin apology tour.
If your skin barrier is already irritated, skip the device entirely. Use a calming routine, moisturizer, and sunscreen until your skin feels normal again. For the exact retinol timing question, I made a separate Medicube Booster Pro with retinol guide.
How I Would Layer Serum With Medicube Booster Pro
For a simple device night, I would do this:
- Cleanse gently.
- Apply toner or mist if your skin likes it.
- Apply hydrating serum while skin is still slightly damp.
- Use Medicube Booster Pro or X2 on a low setting first.
- Apply moisturizer.
- Use sunscreen the next morning. No negotiation.
If your serum dries down before you finish using the device, add a little more serum or mist. Do not drag the device across dry skin. The routine should feel smooth, not like you are sanding a tiny table.
If you are still choosing the device itself, read my best Medicube device 2026 guide. If you already have the regular device, my Medicube Age-R Booster Pro review explains where it fit in my real routine. For the newer premium version, read my Medicube Booster Pro X2 review.
If you want the full first-week schedule, follow my Medicube Booster Pro routine for beginners before experimenting with stronger modes.
If your dry skin is making the device decision harder, my Medicube Booster Pro vs NuFACE for dry skin guide explains why serum slip and gel dry-down matter so much.
If you are using Booster Pro mainly for smoother base makeup, read my Medicube Booster Pro before makeup routine before you start layering sunscreen and cushion over it.
What I Would Buy First
If I were buying one serum for Medicube Booster Pro, I would buy Torriden DIVE-IN first. It is the easiest, safest, most flexible answer for most people.
If I already owned Torriden and wanted a more cushiony night, I would add COSRX Snail Mucin. If my skin were sensitive or reactive, I would keep Skin1004 Centella close. If I wanted brightening, I would use Beauty of Joseon Glow Serum on a separate morning or non-device night.
My friend answer: start boring, then get fancy later. The first goal is not a 12-step device ritual. The first goal is using the device without making your skin mad.
Final Verdict: Best Serum to Use With Medicube Booster Pro
For most people, the best serum to use with Medicube Booster Pro is Torriden DIVE-IN Serum. It is light, hydrating, easy to layer, and low-drama.
Choose COSRX Snail Mucin 96 if you want a thicker cushiony layer, and choose Skin1004 Centella Ampoule if your skin wants calm. Keep brightening actives like Beauty of Joseon Glow Serum for separate routines until you know your skin is comfortable with the device.
Good device skincare is not about using the strongest serum. It is about choosing the serum your skin will still like tomorrow morning.
