Beauty devices promise a lot. Professional-grade results at home, visible lifting, pore reduction, better product absorption — claims that sound great but often disappoint. Korean brand medicube entered this space with their AGE-R line, and the devices went viral on social media. Millions of views, countless before-and-afters, celebrity endorsements.
We wanted to cut through the hype. We tested three AGE-R devices over 8 weeks with controlled before-and-after photography, consistent routines, and honest assessment of what changed and what didn’t.
How At-Home Beauty Devices Work
Most at-home beauty devices use one or more of these technologies:
Microcurrent. Low-level electrical current that stimulates facial muscles, theoretically toning and lifting them. Think of it as a workout for your face.
LED light therapy. Different wavelengths of light penetrate to different skin depths. Red light (630-660nm) stimulates collagen production. Blue light (415nm) kills acne-causing bacteria.
EMS (Electrical Muscle Stimulation). Stronger than microcurrent, EMS causes visible muscle contractions. Used for temporary lifting and firming effects.
RF (Radiofrequency). Heats the deeper layers of skin to stimulate collagen production. Professional RF treatments are well-established; at-home versions use lower energy levels.
The key question is always intensity. Professional devices are powerful. At-home devices are necessarily weaker for safety reasons. Whether the lower intensity still produces meaningful results depends on the device, the technology, and how consistently you use it.
The Devices We Tested
medicube AGE-R Booster Pro
Technologies: EMS + LED + Sonic vibration Treatment time: 10 minutes per session Recommended use: 3-4 times per week
The Booster Pro is medicube’s flagship device. It combines three technologies in one unit: EMS for muscle toning, LED for collagen stimulation, and sonic vibration for product absorption.
What we noticed at week 2: The immediate post-treatment lifting effect was visible from the first use. Jaw looked slightly more defined, cheeks appeared lifted. However, this faded within a few hours — similar to facial massage effects.
What we noticed at week 4: The lifting effect started lasting longer. By mid-month, the post-treatment definition was still visible the next morning. Skin texture also improved — pores appeared slightly smaller and skin surface was smoother.
What we noticed at week 8: This is where we saw genuine, sustained improvement. The jawline definition was consistently better, even on days we didn’t use the device. Skin firmness measured with a skin analyzer showed measurable improvement. Nasolabial folds appeared slightly softer. Product absorption noticeably improved — serums and creams seemed to work better on device-treated skin.
Our verdict: The Booster Pro works, but it requires commitment. Skip it for a week and the benefits fade. Use it consistently 3-4 times per week and you’ll see real results by month two. The immediate lifting effect is a nice bonus, but the real value is the cumulative improvement.
Available in multiple colors: Pink, Black, Lavender, Lemon.
The Mini version is also available for travel or if you want to try the technology at a lower price point. The MINI PLUS+ adds upgraded intensity.
medicube AGE-R High Focus Shot
Technology: Focused RF (radiofrequency) Treatment time: 5 minutes per area Recommended use: 2-3 times per week
The High Focus Shot targets specific areas with concentrated RF energy. It’s designed for wrinkle zones — forehead lines, crow’s feet, nasolabial folds, and lip lines.
What we noticed at week 2: Skin felt tighter in treated areas immediately after use. The warmth was comfortable, not painful. Treated areas had a subtle plumping effect.
What we noticed at week 4: The plumping effect became more persistent. Forehead lines appeared softer, though deeper wrinkles hadn’t changed significantly. The skin texture in treated areas was noticeably smoother.
What we noticed at week 8: Fine lines showed genuine improvement. The forehead lines that were visible at rest were now only visible in certain lighting. Nasolabial folds appeared shallower. Deep-set wrinkles were slightly softer but not dramatically changed.
Our verdict: Effective for fine lines and moderate wrinkles. Don’t expect it to erase deep wrinkles — that requires professional-grade RF or injectable treatments. But for prevention and early intervention, this device delivers visible improvement that justifies the investment.
The PLUS+ version offers upgraded power for those wanting more intensity.
medicube AGE-R Booster V Roller
Technology: EMS + Vibration Treatment time: 5 minutes Recommended use: Daily
The V Roller focuses on the jawline and lower face. The V-shaped design hugs the jaw and delivers EMS stimulation to the muscles responsible for facial contour.
What we noticed at week 4: A subtle but real improvement in jawline definition. The V Roller was the quickest of the three devices to show sustained results, perhaps because its targeted design delivers focused stimulation to a specific area.
What we noticed at week 8: Consistently more defined jawline, particularly noticeable in photos. Two testers who’d been considering filler for jawline definition decided to continue with the V Roller instead.
Our verdict: If jawline definition is your primary concern, this is the most targeted and effective tool in the lineup. The daily 5-minute commitment is manageable and the results compound quickly.
Device Pairing: The Optimal Routine
For maximum results, we found this combination worked best:
Morning (5 min): V Roller on jawline → apply serum → moisturizer Evening, 3x/week (15 min): Booster Pro on full face → High Focus Shot on wrinkle zones → night cream
Always apply a conductive serum or gel before using any device. The medicube AGE-R Vita K Cream works well:
The vitamin K helps with any mild redness from the devices while providing excellent conductivity.
Who Should Buy These Devices
Good candidates:
- People in their late 20s+ wanting to prevent and address early aging signs
- Anyone committed to using them consistently (3-4 times per week minimum)
- People who want to extend time between professional treatments
- Those who prefer at-home treatments over clinic visits
Not ideal for:
- Anyone expecting dramatic results in a week
- People who already skip their basic skincare routine
- Those with deep wrinkles seeking dramatic correction (see a professional)
- People with pacemakers, metal implants in the face, or who are pregnant
The Bottom Line
medicube AGE-R devices work. They’re not miracle workers, and they require genuine commitment, but the results are real and measurable. The key insight from our testing: consistency matters more than intensity. A 10-minute session 4 times a week beats an occasional 30-minute session.
Think of them as exercise for your skin. You won’t see abs after one workout, but after two months of regular training, the change is undeniable. The same principle applies here.
