In Korea, a beauty device isn’t a gadget you buy once and forget about. It’s a step. It has a place in the routine, it takes five minutes, and it happens most days — the same way cleansing twice does.
That’s the part that gets lost when these devices travel. Here they arrive looking like a treat, or a gimmick, and most people never learn what to actually do with one. So this is the proper guide: why Korea got here first, then each of the two Medicube AGE-R devices we stock, one at a time — what it is, what it does, how to use it, and — the bit nobody tells you — exactly what to use it with.
Why Korea got here first
The usual explanation is that Koreans are obsessed with skincare. The more useful explanation is access.
Going to a dermatologist in Korea is an errand, not an event. Of the clinics opened in Korea in the first seven months of 2025 by doctors without a specialty, 83% registered dermatology — 146 out of 176, up 36% on the year before, with more than a fifth of them in two Seoul districts alone. When professional skin treatments are that normal and that visible, a device that brings a gentler version of the same idea home is an obvious buy. Medicube’s own Korean line for AGE-R translates roughly as “clinic care everyone can have”.
The market followed. Euromonitor put the Korean home beauty device market at around £115 million in 2019, rising to roughly £365 million by 2024 — better than tripling in five years. Medicube’s parent company APR launched its first AGE-R device in March 2021. By January 2026 it had announced six million devices sold, more than 60% of them outside Korea.
Six million is the number that matters. People don’t repeat-buy and recommend a device that does nothing.
The two devices we stock
AGE-R is Medicube’s range of handheld home devices, and we carry two of them.
The AGE-R Booster Pro is the full-size one: four modes covering absorption, pores, and facial contour. The AGE-R Booster Pro Mini is a slim pen that does one of those four jobs — the main one — and does it beautifully.
Here’s each in turn, so you can see which is yours.
Device one: the AGE-R Booster Pro
The full-size device, in black. A wide surgical steel head, five intensity levels, five LED colours, sonic vibration, and a sensor that only fires the light once the head is against your skin. 155g, USB-C charging.
What its four modes do
In Medicube’s own words, with what’s doing the work behind each one.
| Mode | What Medicube says it does | The technology |
|---|---|---|
| Booster | “Enhances the absorption of active ingredients… helping to boost overall glow and skin vitality” | Electroporation — brief electrical pulses that temporarily make the skin’s surface more permeable |
| Air Shot | “Helps to improve the appearance of pores… efficient care of wide-pored areas like the T-Zone and U-Zone” | A pulsed electrical treatment aimed at the pore. Nothing pierces the skin, despite the name |
| MC | “Cares for more volumised appearance in areas prone to sagging, such as around the eyes and mouth” | Microcurrent — a very low-level current passed across the face |
| Derma Shot | “Optimised to target areas of the skin where more definition is needed… more refreshed and defined-looking skin” | Mid-frequency EMS, working on the facial muscles |
What Medicube’s testing found
Tested through the Global Institute of Dermatological Sciences. These are the brand’s own figures rather than independent published research, and Medicube notes results vary by skin type — but they’re specific, and they’re what the company stands behind.
- +763.3% boost in skin absorption efficiency
- +70.4% plumper-looking skin
- −34.56% appearance of pores
- 100% of testers agreed their skin felt smoother, and that their complexion looked clearer and more radiant
How to use it
Medicube’s recommended order is Air Shot first, then Booster, then MC, then Derma Shot.
- Air Shot — on cleansed, dry skin, before anything else. 5 minutes, two or three times a week
- Booster — over a light serum or ampoule
- MC and Derma Shot — over a richer, more viscous cream or gel
Those last three run 5–10 minutes, up to three times a day. Start at intensity level 1, and stay at 1 anywhere the skin is thin — around the eye socket, the sides of the nose, the mouth. Wipe the metal head with a soft damp cloth afterwards and let it dry.
Who it suits: someone who wants pore care, contour work and absorption in one device, and who’ll enjoy having modes to work through rather than finding them a faff.
Device two: the AGE-R Booster Pro Mini
This is the second device we stock, and for most people it’s the one to start with.
The Mini isn’t a shrunken Booster Pro. It’s built to do a single job — the absorption step, the one the whole AGE-R range is known for — with red and blue LED alongside. There’s no pore mode and no EMS contour mode here; those stay on the full-size device. What you get instead is the range’s headline function in something that weighs 75g, is shaped like a pen, and takes five minutes.
That shape matters more than it sounds. A slim head reaches the places a wide one handles clumsily: along the jaw, either side of the nose, around the eye socket. And it fits in a wash bag.
What Medicube’s testing found
- +562% improvement in skin absorption rate
- After a single use: radiance +30.97%, texture +7.74%
That absorption figure is the whole premise, and it’s why the Mini is the better first buy than people expect. You already own good serums. Most of what you apply sits on the surface and comes off on your pillow. This changes that ratio — which makes it the cheapest real upgrade available to a routine you’ve already paid for.
How to use it
Pick red or blue, use it for 5–10 minutes, up to three times a day, always over skincare or a sheet mask. Glide it slowly; press gently for two or three seconds on a spot you want to work on. Keep it moving and keep it brief near the eyes. Same as the Pro: wipe the head afterwards.
Two practical things nobody mentions until it annoys you: it doesn’t come with a charging cable (USB-C, you’ll have one), and it doesn’t claim water resistance, so keep it out of the shower.
Who it suits: anyone starting out with devices, anyone who travels, and anyone who wants one simple habit rather than a routine to learn. Nothing to programme — pick a colour, five minutes, done.

What to use it with
This is the question we’re asked most, and it’s the right one. The device doesn’t add anything to your skin — it moves what you’ve already put there. So what you pair it with is the treatment. A device over the wrong product is just a nice massage.
Two rules cover almost all of it:
- Booster mode, and the Mini, want something light — a serum, ampoule, essence, or the essence from a sheet mask
- MC and Derma Shot want something richer — a cream or gel-cream, so the head glides properly and the current carries
Pick by what your skin needs
| If your skin needs… | Use the device over… |
|---|---|
|
Glow and plumpness the all-rounder |
Medicube PDRN Pink Peptide Serum — light, sinks fast, and it’s from the same range as the device. This is the one we’d hand you first |
| Dullness and brightness | Arencia Holy Hyssop Serum 30 — 30% Vitamin ACE Complex with French hyssop, and it’s a serum-gel, which is exactly the texture a device wants. Or Arencia Vitamin C Booster Shot for a straighter hit of vitamin C |
| Dark spots and pigmentation | Anua Niacinamide 10% + TXA 4%, then Medicube TXA Niacinamide Capsule Cream over the top for the richer modes |
| Dryness and dehydration | Haruharu Wonder Black Rice Probiotics Barrier Essence — milky, cushioned and one of the best textures in the shop for gliding a device head. Or COSRX Advanced Snail 96 Mucin Power Essence. Add iUNIK Propolis Vitamin Synergy Serum if dullness and redness are in the mix too |
| Sensitivity and redness | Beauty of Joseon Calming Serum, or SKIN1004 Madagascar Centella Ampoule |
| Firmness and fine lines | Be The Skin Vitavita Raspberry PDRN Ampoule, or numbuzin No.9 NAD Bio Lifting Essence |
And the cream for the MC and Derma Shot modes?
Those two want body and slip — a thin watery serum won’t carry the current well and the head will drag. Any of these work:
- Medicube Collagen Jelly Cream, 110ml — the classic pairing. This is the one Medicube itself puts alongside the AGE-R, and once you’ve used it you understand why: the jelly texture holds under the head instead of sliding off or soaking straight in, so the MC and Derma Shot modes glide for the full five minutes. If you only buy one thing to go with your device, buy this
- Medicube PDRN Booster Moisturizing Gel, 300ml — the everyday one. A big tube of exactly the right consistency, so you’re not getting through your good serum on a daily habit. Doubles as a light gel moisturiser on its own
- Medicube PDRN Pink Hyaluronic Moisturising Cream, 50ml — richer, same range, for drier skin or colder months
- Biodance Skin-Glow Essence Cream, 50ml — a lighter essence-cream if a full cream feels like too much
Two things to leave out of a device session
Save your strong acids and your retinoid for the nights you skip the device. Driving an exfoliating acid or a retinoid deeper isn’t the win it sounds like — it’s how people end up with a stinging, flaking face and blame the device. Use them on alternate nights and everyone stays happy.
And one exception to all of the above: Air Shot mode on the Booster Pro is designed for clean, dry skin before any skincare. That one wants nothing on your face at all.
You don’t have to buy a branded gel. Medicube’s own guidance is that no special gel is required — use the device alongside your regular skincare. What’s not optional is having something wet and slippy between the metal head and your skin: Medicube notes that without a product on the skin the energy isn’t delivered properly. So if you already own a good hydrating serum or essence, start there. The dedicated gel is a convenience, not a gate.
Or buy them together

What I’ve found, using mine
I use the AGE-R devices myself, most days, and I’ll tell you what I’ve actually noticed rather than what I’m supposed to say. My pigmentation looks better than it did — more even, less of the patchiness I’d stopped expecting to shift. And the dullness has gone. My skin looks lit from underneath rather than flat, and makeup sits on it far better. It took weeks, not days, and it’s the consistency that did it. That’s my experience with my skin; yours may land differently. — Irel
What to expect, and when
Give it eight to twelve weeks of consistent use before you judge it, and be realistic about the shape of the result. Not a different face. More like: skin that holds hydration better through the day, tone that looks more even, makeup sitting more smoothly, less of that flat dull look by Thursday. Modest, cumulative, and worth having.
These are maintenance tools rather than one-off fixes — the result comes from the habit, not the purchase, and it fades if the habit stops. One honest note on the wider category, too: for the technologies inside every device of this type, the independent published research is thinner than the marketing across the industry suggests, and the testing above is Medicube’s own. We’d rather say so. It’s also why, if any brand tells you a handheld device treats acne or rosacea, you should walk away — that’s a medical claim no cosmetic device is allowed to make.
The generation question, answered straight
Medicube launched the Booster Pro X2 in Korea in March 2026, reaching the UK that June, and there’s a Mini Plus alongside the Mini. We stock the previous generation of both, and here’s exactly what that means.
On the full-size device, no new treatment technology was added. The X2 has seven modes to the Booster Pro’s four — but the four treatment modes are the same four, under the same names. What’s new is a Dual Mode running two of them at once across a split head, a Mask Mode tuned for sheet masks, app connectivity, a sixth intensity level and a bigger head. Faster and more connected, rather than doing anything the Booster Pro can’t.
On the small device the jump is bigger: the Mini Plus adds a third LED colour, five intensity levels, app connectivity, water resistance and clip-on accessory heads — which, worth knowing, don’t fit the original Mini.
Why we still stock this generation: the technology that does the work is identical, and the price isn’t. You’re giving up speed, an app and a couple of convenience modes — not results. For most people starting out, that’s the right trade, and we’d rather say so than let you find it on a comparison site afterwards.
Before you start: who shouldn’t use one
Short section, but the important one. It applies to both devices.
Don’t use an electrical facial device if you have a pacemaker or any implanted electronic device, suspected heart problems, a seizure disorder, an active cancer or tumour, or if you’re pregnant. These are standard manufacturer contraindications across the category. Over-18s only.
Medicube’s own guidance adds: not over wounds, recent surgical sites, or anywhere with implanted metal, plastic or silicone; not over the Adam’s apple; not on inflamed acne or actively irritated skin; take jewellery off first; and never hold it on one spot.
Around the eyes, stay on the orbital bone at the lowest setting — never on the eyelid or near the eyeball itself. Where a device comes with eye protection, use it; sunglasses aren’t a substitute.
If you have deeper skin, visible light has been shown to induce pigmentation in Fitzpatrick type IV skin (Mahmoud and colleagues, Journal of Investigative Dermatology, 2010). That study used a broad visible-light source rather than a narrow-band LED, so it’s a reason for care rather than a finding about any particular device — but if you have melasma or post-inflammatory hyperpigmentation, have a word with a clinician first.
If you’ve had injectables, manufacturers commonly suggest waiting around two weeks. Follow whatever the clinician who treated you says.
If you’re on isotretinoin or anything photosensitising — strong acids and retinoids, some antibiotics, some blood pressure medication — check first, and don’t put light therapy on top of a retinoid the same night.

This article is general guidance and not medical advice — we are not dermatologists. If you have a skin condition, take prescribed medication, are pregnant or have any of the health conditions listed above, speak to your GP or dermatologist before using an electrical beauty device. Always patch test new products, and start any device with adjustable intensity at its lowest setting.
