The Medicube AGE-R Booster Pro might be the most recommended skincare device on the internet right now. It is all over TikTok, it sits permanently on best-seller lists, and clients ask me about it more than any other gadget. As a trained cosmetologist, my default setting with at-home devices is skepticism: most of them are vibrating paperweights. So this review is the honest version. What the Booster Pro actually does, what it absolutely will not do, the annoying parts nobody mentions in the viral videos, and exactly who should and should not spend the money.

What the Booster Pro actually is

The Booster Pro is a handheld 6-in-1 electrical skincare device. Inside one wand you get electroporation (the headline feature), microcurrent, EMS muscle stimulation, an “electric needle” mode, sonic vibration, and LED light. In practice, those technologies are bundled into four modes:

Booster mode is the one that made this device famous. It uses electroporation: tiny electrical pulses that temporarily create microchannels in the skin so your serums absorb dramatically deeper than they would from just patting them in. Medicube claims absorption increases of several hundred percent. I am always cautious with manufacturer numbers, but the real-world effect is visible: serums stop sitting on top of the skin and your products simply work harder. This mode is gentle enough for daily use, morning and night.

MC mode is microcurrent, the same technology behind devices like the NuFACE. It delivers a low-level current that gives the skin a temporarily lifted, bouncy, more awake look. Great before an event, and pleasant to use with a sheet mask.

Derma Shot mode is EMS, meaning it stimulates the actual facial muscles rather than just the skin. Think of it as a light workout for your face and jawline. It is the mode for firmness and contour over time.

Air Shot mode is the intense one. It uses high-voltage micro-sparks to create tiny invisible channels in the skin surface, aimed at pore refinement and texture. I need to be honest with you here: this mode is not pleasant. It zaps, it can leave a faint singed smell (it is burning off peach fuzz), and it can leave cheeks pink for a bit. It is a 2 to 3 times per week mode at most, and if your skin is sensitive or reactive, you can skip it entirely and still get most of the device’s value.

What it does well

After working with this device and watching clients use it consistently, three benefits hold up:

1. Product absorption is genuinely better. This is the core value. If you have invested in good serums, the Booster mode makes them noticeably more effective. Hydrating and repairing serums are the perfect partners here: think hyaluronic acid, peptides, and especially PDRN. If you have read my Korean PDRN serum comparison, this device is the single best way to get more out of whichever serum you picked.

2. Texture and pores improve with consistent use. The most credible long-term reviews and my own observations agree: several weeks of consistent use produces smoother texture and visibly refined pores. Long-term users report improvements in post-acne marks as well.

3. The glow is real. The combination of better absorption, circulation from the sonic vibration, and regular massage gives skin that plump, lit-from-within quality that the glass skin look is built on. It slots perfectly into the routine I laid out in the complete Korean glass skin guide.

What nobody tells you before you buy

This is the part the 15-second videos leave out, and it is where most disappointed buyers went wrong.

Results are rented, not owned. This device rewards consistency and punishes neglect. Users who stick with it daily see cumulative improvement. Skip a couple of weeks and the bounce, glow, and pore refinement quietly fade. If you know yourself and you will not use a device 5 to 10 minutes a day most days, do not buy it. That is not a flaw unique to Medicube, it is how every at-home device works, but nobody puts it in the ad.

It needs slip to glide. The device must move smoothly over skin, which means you need a water-based gel or a generous serum layer underneath. A thin layer of a watery serum dries down too fast mid-session. Medicube sells a Booster Gel designed for this (check current price), but any water-soluble gel or gel-texture serum works. Just budget for the fact that you will go through product faster.

Air Shot mode is not for everyone. Covered above, but worth repeating: sensitive skin, rosacea-prone skin, or anyone currently using strong actives should treat Air Shot with caution or skip it. Start at level 1 if you try it.

It is a time commitment. A proper session is around 5 to 10 minutes per mode you use. It is pleasant time, but it is time.

Booster Pro vs Ultra Tune 40.68: which Medicube device should you buy?

Medicube now sells a higher-end sibling, the AGE-R Ultra Tune 40.68, and the two get confused constantly. Here is the clean way to think about it:

Feature	Booster Pro	Ultra Tune 40.68
Core technology	Electroporation + microcurrent + EMS	High-frequency radiofrequency (40.68MHz) + microcurrent
Best for	Glow, hydration, absorption, pores, texture	Lifting, firming, fine lines, deeper anti-aging
Feel	Gentle (except Air Shot)	Warming, RF heat
Routine role	Everyday all-rounder	Targeted elasticity treatment
Price tier	Mid	Premium
Where to buy	Check current price →	Check current price →

The short answer: if your goal is the glass skin look, better absorption, glow, and pore refinement, the Booster Pro is the right buy and the better value. If your primary concern is sagging, loss of firmness, and deeper wrinkles, the Ultra Tune (check current price) targets that more directly with radiofrequency. For most people under 45 building a Korean skincare routine, the Booster Pro covers more ground for less money.

Who should buy it, and who should skip it

Buy it if:

• You already own serums you love and want them to work harder
• You are chasing glow, smoothness, and refined pores rather than dramatic lifting
• You will realistically use it most days, even just the Booster mode
• You want one device that replaces several single-purpose gadgets

Skip it if:

• Your routine is inconsistent and a device would join the drawer of abandoned gadgets
• Your primary concern is significant sagging or deep wrinkles (look at RF devices like the Ultra Tune instead)
• Your skin is highly reactive and even mild electrical stimulation sounds like a bad time
• You have not built a basic routine yet. A device amplifies a routine, it cannot replace one. Start with the glass skin routine first and add hardware later.

FAQ

How long until I see results from the Booster Pro?

Immediate effects (plumper, more hydrated look) show up after the first few sessions. Structural improvements like refined pores and smoother texture take 4 to 8 weeks of consistent use. The key word is consistent.

Can I use the Booster Pro every day?

Yes. Booster, MC, and Derma Shot modes are designed for daily use, 1 to 3 sessions a day. Air Shot mode should stay at 2 to 3 times per week maximum.

Do I need Medicube products to use it?

No. It works with any water-based serum or gel. You just need enough slip for the head to glide. Avoid using it over strong actives like high-percentage acids or retinoids, since driving those deeper can mean irritation.

Is the Booster Pro safe for sensitive skin?

The Booster and MC modes are generally well tolerated. Air Shot mode is the one to approach carefully or skip. If you have an active skin condition, are pregnant, or have implanted medical devices, check with your doctor before using any electrical skincare device.

Booster Pro or Ultra Tune for beginners?

Booster Pro. It is more versatile, more comfortable, and supports the hydration-and-glow goals most people start with. The Ultra Tune is a targeted lifting tool that makes more sense as a second device or for primarily anti-aging goals.

Product details and modes reflect the current Booster Pro at the time of writing. Formulations, features, and availability change, so confirm specifics on the product page before buying.

Sources and further reading

This review reflects the hands-on experience of Chelsey Schade, a trained cosmetologist, alongside the published evidence on the technologies inside this device. A note on that evidence: most peer-reviewed research on electroporation studies controlled drug delivery in lab settings, and the microcurrent and EMS studies tend to show modest improvements rather than dramatic ones. The science supports the mechanisms in principle. It does not validate any single brand’s specific percentage claims, which is why this review leans on real-world use rather than marketing numbers.

• Electroporation as a transdermal delivery method: Transdermal Drug Delivery Systems: Methods for Enhancing Skin Permeability and Their Evaluation (PMC, 2025). A review of physical permeability enhancers, including how electroporation temporarily opens channels in the skin barrier and how that effect fades over hours.
• Electroporation efficiency and limits: Electroporation as an efficient physical enhancer for skin drug delivery (PubMed). Establishes that electroporation increases transdermal delivery, with results depending heavily on pulse settings and the molecule involved.
• At-home microcurrent and EMS, measured results: systematic review evidence on device-based facial rejuvenation, and split-face studies on at-home microcurrent and EMS devices reporting improvements in dermal density and the look of fine lines. The effects measured are real but modest, and strongest when multiple technologies are combined.

Always follow the manufacturer’s guidance, and skip electrical-stimulation modes if you are pregnant or have a pacemaker or other implanted electronic device. If you have a condition like rosacea or very reactive skin, introduce any new device slowly and stop if it causes irritation. When in doubt, check with your dermatologist.
