The Device That Made Me Rethink My Entire Routine
I bought the Medicube AGE-R Booster Pro in late December after seeing it on display at an Olive Young in Myeongdong. The sales associate told me it was their top-selling device for the third consecutive month. At 259,000 KRW (roughly $179 USD), it was not an impulse purchase — I went home, researched it for two days, read Korean reviews on Hwahae and Naver, watched four YouTube review videos, and then went back to buy it. Two months later, it has fundamentally changed how I think about skincare. Not because it replaced my products, but because it made them work dramatically better.
The AGE-R Booster Pro is a six-in-one beauty device that combines electroporation, microcurrent, EMS (electrical muscle stimulation), electric needle technology, LED light therapy, and sonic vibration. If that sounds like a lot of buzzwords, I understand the skepticism. I was skeptical too. But each technology serves a specific purpose, and the combination creates results that no single skincare product can deliver on its own.
What Each Technology Actually Does
Electroporation is the star feature. It uses brief electrical pulses to temporarily create micro-channels in your skin, allowing active ingredients from your serums and essences to penetrate 17 to 20 times deeper than they would through passive absorption. This means the expensive vitamin C serum you have been applying with your fingers? It has been sitting mostly on the surface of your skin. With electroporation, those actives actually reach the dermis where they can make a difference. This single feature justified the purchase price for me.
The microcurrent function delivers low-level electrical stimulation that mimics your body’s natural bioelectric currents. It targets facial muscles, promoting a lifting and toning effect. Think of it as a very gentle facial workout. EMS takes this further with stronger muscle contractions — during the first use, I could feel my jawline muscles engaging in a way that was unfamiliar but not uncomfortable. The electric needle technology (Medicube’s proprietary version of microneedling without actual needles) creates micro-stimulation that boosts collagen production. LED light therapy offers red light for anti-aging and blue light for acne. Sonic vibration assists with product absorption and lymphatic drainage.
My Two-Month Results
I have been using the Booster Pro five days a week (resting weekends to let my skin recover) for exactly two months. Morning routine: cleanse, apply COSRX Advanced Snail 96 Mucin Power Essence, then run the Booster Pro on the “Lifting” preset for about eight minutes. Evening routine: double cleanse, apply my PDRN serum, then run the “Deep Moisture” preset for ten minutes.
The results have been noticeable enough that my coworker asked if I had gotten “something done.” The most visible change is in my jawline definition — the microcurrent and EMS combination has created a subtle but real lifting effect that makes my face look slightly more contoured. Pore visibility on my cheeks has decreased, which I attribute to the improved product absorption from electroporation. The overall “glow” factor of my skin has improved — it looks healthier, more hydrated, and reflects light differently. None of these changes are dramatic individually, but together they create a “better version of my skin” effect.
The Kylie Jenner Connection
The Booster Pro’s international fame largely comes from a photo of Kylie Jenner using the device, which circulated on social media in late 2025. Whether Jenner was paid for the placement or genuinely uses the device is unclear, but the impact on sales was immediate. Medicube’s US sales reportedly tripled in the weeks following the photo’s viral spread. The device is now available at Ulta, Amazon, and Walmart in the United States, priced at $159 to $179 depending on the retailer.
In Korea, the celebrity endorsement ecosystem works differently. Korean beauty influencer Risabae (who has 4 million YouTube subscribers) did a detailed review showing before-and-after thermal imaging of her face — the increased blood circulation after using the device was visible in the temperature data. Dermatologist Dr. Pi, a popular Korean skincare YouTube creator, gave it a cautious endorsement, noting that the electroporation technology is “clinically well-supported” but recommending users consult a dermatologist before using the microcurrent function if they have any skin conditions.
What I Wish Were Better
No product is perfect, and the Booster Pro has legitimate drawbacks. The battery life is mediocre — I get about five full sessions before needing to charge, and the charging cable is a proprietary connector (not USB-C), which is annoying in 2026. The device is also louder than I expected during the sonic vibration mode — not loud enough to wake a roommate, but enough to be noticeable in a quiet apartment. The companion app (AGE-R app) is functional but clunky, with occasional Korean-to-English translation errors that make the guided routines confusing for non-Korean users.
The price is also worth discussing honestly. At 259,000 KRW in Korea (or $179 in the US), the Booster Pro is not cheap. But compared to professional facial treatments — a single microcurrent facial at a Gangnam clinic costs 150,000 to 300,000 KRW per session — the device pays for itself after two or three uses. The long-term economics are compelling if you commit to regular use.
Should You Buy It
If you already have an established skincare routine with quality products and you want to see better results from those products, the Medicube AGE-R Booster Pro is worth the investment. The electroporation technology alone makes a measurable difference in how well your serums absorb, and the lifting effects from microcurrent and EMS are real if subtle. If you are looking for dramatic, surgery-like results, manage your expectations — this is a maintenance and enhancement tool, not a miracle device.
For Korean beauty enthusiasts who already spend significant money on serums and essences, the Booster Pro is arguably a smarter investment than buying yet another expensive product. It makes everything you already own work harder. That, more than any celebrity endorsement, is why this device has become a staple in Korean bathrooms across the country.
