Why We Chose It

The medicube AGE-R Ultra Tune 40.68 is one of the most interesting firming devices in the collection because it combines two technologies that do different jobs.

The 40.68MHz radio frequency delivers controlled warming energy to support skin elasticity and a firmer-looking appearance, while microcurrent is used around areas like the forehead, eyes, smile lines, and mouth to support facial volume and definition.

Medicube calls this Dual Tune-Wave™ technology, and the clinical results give the combination real weight. The brand reports 29.8% improvement in forehead lines, 13% improvement in neck lines, 10% improvement in glabellar lines, 6.6% improvement in smile lines, and 6.1% improvement in crow’s feet.

We also like how easy Medicube has made the routine. There is no separate conductive gel to buy or remember. You finish your skincare, let it absorb, then use the device directly over the skin.

The six-tip treatment head only delivers energy when all six contact points are touching the skin, which helps keep the treatment controlled as you move across the face.

And unlike many RF devices that are treated more like an occasional procedure, Ultra Tune is designed for regular use. Medicube says it can be used daily, which makes it much easier to build into an actual skincare routine. 

Results Worth Noticing

29.8% improvement in forehead lines
Medicube’s strongest reported line-specific result.

13% improvement in neck lines
A useful result for anyone focused on firmness below the jawline.

10% improvement in glabellar lines
Reported in Medicube’s human application testing.

6.6% improvement in smile lines

6.1% improvement in crow’s feet

The numbers are not dramatic across every area, but that actually makes the testing feel more believable. The strongest response appears to be in forehead and neck lines, while other areas show more modest improvement.

Technology

40.68MHz Radio Frequency + Microcurrent

The AGE-R Ultra Tune combines radio frequency and microcurrent in one treatment system.

40.68MHz Radio Frequency
Delivers warming energy into the skin to support elasticity and a firmer-looking appearance over time.

Medicube notes that Ultra Tune operates at a frequency around 20 times higher than its older Deep Shot device, giving it a different RF profile and allowing it to be used without a separate gel.

Microcurrent
Uses low-level electrical stimulation to support facial volume and definition in areas such as the forehead, around the eyes, smile lines, and mouth.

Together, Medicube describes the system as Dual Tune-Wave™ technology, designed to pair elasticity-focused RF care with contour-supporting microcurrent.

Our Take

This is the Medicube device we would look at if firmness and visible lines are the main concern.

The Booster Pro X2 is the more versatile all-rounder, but Ultra Tune has a much narrower job: RF-based elasticity care, facial volume, and line smoothing.

That focus is what makes it useful.

You are getting a higher-frequency RF treatment, microcurrent support, and actual line-specific clinical data, without having to add a conductive gel or turn the routine into a project.

The forehead and neck results are the ones that catch our attention most. A 29.8% improvement in forehead lines and 13% improvement in neck lines give Ultra Tune a clearer identity than just “another firming device.”

If your priority is glow, pores, and multiple skincare concerns, X2 makes more sense. If you care more about firmness, elasticity, and visible lines, Ultra Tune is the more targeted choice. 

Pairs Beautifully With

medicube Booster Pro X2
The strongest companion if you want to split your routine between multi-concern skincare care and more targeted RF firming.

medicube PDRN Pink Peptide Serum
A nice pairing when you want the skincare side of the routine to focus on hydration, bounce, and firmer-looking skin.

medicube Collagen Jelly Cream
Works well as a richer finishing step in a firmness-focused routine.

Hydrating Peptide Serum
Useful before the device as long as it is fully absorbed, especially if your goal is plumpness and elasticity.

Barrier-Supporting Moisturizer
A simple way to keep the routine comfortable and hydration-focused.
