If you are comparing Medicube Booster Pro X2 vs Ultra Tune 40.68, do not choose by counting modes.
These are two premium Medicube devices built around different buying priorities.
As checked on Medicube’s U.S. store on September 9, 2026:
- Booster Pro X2: $249
- Ultra Tune 40.68: $350
That is a $101 difference at the currently checked official prices.
But Ultra Tune does not cost more because it gives you more modes. Booster Pro X2 is actually the broader multi-mode device. Ultra Tune is the more specialized RF + microcurrent option built around elasticity and line-focused care.
My buying rule: choose Booster Pro X2 if you want one premium device to cover several different skincare routines. Choose Ultra Tune 40.68 if RF-focused firming and elasticity care are specifically why you are shopping.

Medicube Booster Pro X2 vs Ultra Tune 40.68: Quick Verdict
| If this sounds like you | Better fit |
|---|---|
| You want one premium device with the broadest range of routines | Booster Pro X2 |
| You care about glow and skincare absorption | Booster Pro X2 |
| You regularly use essence-rich sheet masks | Booster Pro X2 |
| You want Dual Mode plus app-based AI guidance | Booster Pro X2 |
| You specifically want RF-focused elasticity care | Ultra Tune 40.68 |
| Firming and visible line care are your main device goals | Ultra Tune 40.68 |
| You want a more specialized device rather than many different routines | Ultra Tune 40.68 |
| You are not sure what your main goal is | X2—or reconsider a cheaper Medicube first |
Short version: X2 is the more flexible purchase. Ultra Tune is the more targeted purchase.
The Real Difference: Multi-Mode Care vs RF-Focused Care
Medicube lists seven total skin solutions for Booster Pro X2:
- Booster
- Air Shot
- MC
- Derma Shot
- Dual
- Mask
- AI
The device also has six intensity levels.
AI Mode is available exclusively through the AGE-R app. The standard device modes can be used without the app, although features such as AI Mode, Dual Mode customization, remote control and personalized reports require the app.
Ultra Tune takes a different approach.
Medicube explicitly describes Ultra Tune 40.68 as an RF + MC Dual Energy device. Its reason to exist is not to give you seven different skincare workflows. It concentrates more heavily on elasticity and line-focused care.
That difference matters more than the number of modes printed on a product page.
X2 asks: Which type of skincare routine do you want to do today?
Ultra Tune asks: Is RF-focused firming care the main reason you are buying a device?
Choose Booster Pro X2 If You Want the Premium All-Rounder
X2 makes more sense for most people who want a premium Medicube device but do not want to commit the entire purchase to one main technology.
Its biggest advantage is flexibility.
Booster Mode
Medicube positions Booster Mode around radiance, hydration and skincare absorption.
Air Shot Mode
Air Shot is the skincare-free workflow and is positioned around pores, excess sebum and uneven-looking texture.
MC Mode
This mode is positioned around plumper-looking, firmer-looking skin and facial definition.
Derma Shot Mode
Derma Shot is a separate facial-definition-focused mode.
Dual Mode
Dual Mode lets you combine two compatible care modes in one routine. The combinations can be customized through the AGE-R app.
Mask Mode
Mask Mode is designed to be used over a sheet mask. Medicube specifically recommends essence-rich sheet masks rather than gel masks.
AI Mode
AI Mode uses the AGE-R app to recommend personalized care based on skin condition and skincare habits. It is an app-exclusive feature rather than a fully independent hardware mode.
This is why X2 is easier to justify when your routine changes from day to day.
One night might be a serum-and-Booster routine. Another could be a sheet-mask session. Another might focus on MC or facial definition.
You are paying for routine flexibility.

Retailer pricing, stock, shipping availability, seller details, warranty terms and return policies can change. Compare the final checkout conditions rather than assuming one retailer is always the better deal.
Choose Ultra Tune 40.68 If Firming Is the Point
Ultra Tune becomes easier to justify when you can finish this sentence:
“I am buying a beauty device primarily because I want RF-focused elasticity and line care.”
Medicube describes Ultra Tune around its Dual Tune-Wave system and labels the device RF + MC Dual Energy.
The device is not trying to compete with X2 by offering seven separate skin solutions.
Instead, it concentrates on a narrower buying purpose.
That is why I would not call Ultra Tune “worse value” simply because it has fewer modes.
Feature count and treatment category are not the same thing.
If you mainly want:
- glow
- skincare absorption
- sheet-mask use
- different routines on different days
- broader app-based customization
X2 is the cleaner purchase.
If you mainly want:
- RF-focused home care
- elasticity-focused treatment
- visible line care
- a dedicated firming routine
Ultra Tune is the more logical fit.
Medicube also positions Ultra Tune’s microcurrent function around facial-contour areas such as the smile lines and mouth area.
For the eye area, follow the treatment-zone instructions carefully. Medicube says to avoid the eyelids and directly below the eyes, and recommends beginning at the lowest intensity around permitted outer-eye areas.

Why Is Ultra Tune More Expensive If X2 Has More Modes?
This is probably the most useful question in the comparison.
At the official U.S. prices checked for this article, Ultra Tune costs $101 more than Booster Pro X2.
That does not mean Medicube has proven Ultra Tune provides $101 more visible improvement.
It also does not mean X2 is automatically better because it has more functions.
You are comparing two different product positions:
Booster Pro X2: premium multi-purpose device.
Ultra Tune 40.68: premium specialized RF + microcurrent device.
The right question is not:
“Which gives me the most modes per dollar?”
It is:
“Which expensive feature set am I actually going to use?”
Does X2’s “2X Power” Make It More Powerful Than Ultra Tune?
Do not use the “2X Power” label to answer this comparison.
Medicube states that X2’s 2X claim is based on measured power density in W/cm² compared with the original Booster Pro, with the measurement attributed to Korea Testing Laboratory.
The comparison is not against Ultra Tune 40.68.
And it does not establish twice the:
- hydration
- firming
- pore improvement
- skincare absorption
- long-term visible result
The verified claim is a hardware-output comparison with the previous Booster Pro generation—not proof that X2 delivers twice the cosmetic outcome.

What Does Independent Evidence Say About Home RF?
There is independent research on home-use RF as a device category.
A randomized 12-week split-face trial enrolled 33 women aged 35 to 60, with 32 completing the study. One side of the face was treated with a home-use RF beauty device, while the other side received an anti-aging cosmetic. The RF-treated side showed statistically significant improvements in wrinkles, radiance, skin color and skin thickness compared with the cosmetic-treated side.
However, this study did not test Medicube Ultra Tune 40.68. It supports the plausibility of home-use RF as a category, but it does not establish that Ultra Tune will produce the same magnitude of improvement or the same outcome for every user.
Another eight-week study evaluated a different home-based RF device in 22 women and reported improvement in facial wrinkles, dermal thickness, skin texture and elasticity. Again, this was not an Ultra Tune study.
A 2024 review covering 18 clinical studies of home facial beauty devices—including RF, microcurrent and LED technologies—concluded that these devices may improve aspects of skin aging to some extent, while also emphasizing limitations such as small sample sizes, short follow-up periods and a limited evidence base.
That is the appropriate evidence hierarchy here:
Independent research supports home RF as a plausible cosmetic device category. Medicube’s Ultra Tune-specific claims still come from Medicube’s own product testing.
Do Not Compare Medicube’s Clinical Percentages Head-to-Head
Medicube publishes product-specific human-use test results for both devices.
Those numbers can be useful for understanding what the brand measured under its own test conditions.
But they are not a controlled Booster Pro X2 vs Ultra Tune 40.68 trial.
The devices, treatment modes, endpoints, study methods and participant conditions differ.
So the largest percentage on one product page should not be placed next to the largest percentage on the other product page and used to declare a winner.
There is no verified head-to-head clinical study on the current official product pages showing that one of these devices universally outperforms the other.
Buy for the function you need—not the biggest marketing percentage.
Which One Is Easier to Fit Into a Routine?
Booster Pro X2
Medicube’s guidance varies by mode.
Air Shot is used without skincare and is recommended around two to three times weekly.
Booster, MC, Derma Shot and Dual are used with skincare and can generally be used one to three times daily depending on the routine.
Mask Mode can be used with an essence-rich sheet mask.
X2 gives you more flexibility, but it also gives you more modes and workflows to learn.
Ultra Tune 40.68
Medicube instructs users to complete their skincare routine first and allow the products to absorb before using Ultra Tune.
A dedicated conductive gel is not required.
The device activates only when all six tips are fully in contact with the skin. Medicube instructs users to keep the device moving rather than holding it stationary over one area.
The current official guidance says Ultra Tune can be used daily, one to three times per day, with sessions of roughly five to ten minutes, while adjusting frequency and duration to individual skin condition.
If the heat feels too strong, Medicube instructs users to remove the device from the skin and reduce the intensity.
If you are still unsure where serums, moisturizers and optional devices fit, our Korean skincare routine order guide covers the basic layering logic.
Which Is Better for Firming?
Better fit: Ultra Tune 40.68
If firming and elasticity are the main reasons you are spending this much money, Ultra Tune has the more direct product positioning.
That does not mean X2 has no firming-related functions.
X2 includes MC and Derma Shot modes, and Medicube publishes brand-provided results relating to lines and facial definition.
But X2 spreads its value across several different use cases.
Ultra Tune concentrates more of its reason to exist around RF + microcurrent elasticity care.
That makes Ultra Tune the cleaner goal match—not a clinically proven head-to-head winner.
Which Is Better for Glow and Skincare Absorption?
Better fit: Booster Pro X2
This is where X2 makes substantially more sense.
Booster Mode, Mask Mode and the broader skincare-pairing workflow make X2 the more natural choice if your routine is closer to:
serum → device → hydrated glow
rather than:
dedicated RF-focused firming session
If glow and skincare pairing are the actual goals, I would not pay the Ultra Tune premium merely because RF sounds more advanced.
Which Is Better for Sheet Masks?
Better fit: Booster Pro X2
X2 has a dedicated Mask Mode.
Medicube recommends using it with essence-rich sheet masks rather than thick gel masks.
Ultra Tune is not the device I would buy specifically to improve a sheet-mask routine.
Which Is Better for a Beginner?
If these are the only two choices, Booster Pro X2 is the more flexible purchase.
But neither device is automatically the smartest first Medicube purchase.
Someone who has never maintained a beauty-device routine may be better off starting with a less expensive option before spending $249 or $350.

Do You Need Both Booster Pro X2 and Ultra Tune?
For most buyers, no.
The devices are different enough that a serious beauty-device user could build separate routines around both.
But “they are different” is not the same as “you need both.”
Before buying a second premium device, ask:
- What specific job would the second device do?
- Do I already use my first device consistently?
- Am I buying a genuinely different function—or simply another expensive gadget?
- Would I actually maintain two separate device routines?
If you cannot give the second device a clear job, keep the money.
Who Should Buy Booster Pro X2?
Choose X2 if:
- you want one premium all-round Medicube device
- glow and skincare absorption matter
- you regularly use sheet masks
- you expect to use several different modes
- Dual Mode fits your routine
- you want app-based AI recommendations
- you value flexibility more than RF specialization
At the official U.S. price checked for this article, X2 is also $101 less expensive than Ultra Tune.
Who Should Buy Ultra Tune 40.68?
Choose Ultra Tune if:
- firming is your primary device goal
- RF is specifically the technology category you want
- elasticity-focused care matters more than having many modes
- you already have a stable skincare routine
- you understand that a home device is not the same as an in-office RF procedure
- you are comfortable paying more for a narrower, targeted device
Final Verdict: Booster Pro X2 or Ultra Tune 40.68?
Booster Pro X2 and Ultra Tune 40.68 are not simply two versions of the same device.
Choose Booster Pro X2 for versatility. It is Medicube’s broader multi-mode device, with Booster, Air Shot, MC, Derma Shot, Dual, Mask and app-based AI guidance. It makes the most sense when glow, skincare pairing, pores, sheet-mask use and changing routines are part of why you want a device.
Choose Ultra Tune 40.68 for specialization. It is Medicube’s RF + microcurrent-focused device, positioned around elasticity and line-focused care.
Its higher price does not prove stronger results than X2. It reflects a different device category and a different buying purpose.
At the official U.S. prices checked on September 9, 2026, Ultra Tune was $101 more than Booster Pro X2. Recheck that gap if Medicube changes either price.
Do not choose X2 because its “2X Power” label sounds universally stronger. Medicube defines that claim as a measured power-density comparison with the previous Booster Pro—not with Ultra Tune, and not as proof of twice the visible results.
Most buyers do not need both devices.
Buy X2 for versatility. Buy Ultra Tune for specialization.
Before ordering, compare the current final price, shipping availability, seller, warranty terms and return policy for your country.
FAQ
Is Medicube Booster Pro X2 better than Ultra Tune 40.68?
Booster Pro X2 is the better fit if you want a versatile multi-mode device. Ultra Tune 40.68 is the better fit if RF-focused firming and elasticity care are your main goals. There is no verified head-to-head clinical trial establishing one as universally more effective.
Is Ultra Tune 40.68 worth the extra money?
It can be if you specifically want an RF + microcurrent device for elasticity-focused care. If you mainly want glow, skincare absorption, sheet-mask use or broader routine flexibility, X2 is easier to justify at the currently checked lower price.
Does Booster Pro X2 have RF?
Medicube does not position Booster Pro X2 as its RF-focused device. Its current seven-solution lineup is Booster, Air Shot, MC, Derma Shot, Dual, Mask and AI. Ultra Tune 40.68 is the device Medicube explicitly labels RF + MC Dual Energy.
Which Medicube device is better for firming?
Ultra Tune 40.68 is the more directly firming-focused option because its product positioning centers on RF + microcurrent elasticity and line care. X2 also includes MC and facial-definition functions, so this is a question of specialization rather than “firming versus no firming.”
Do I need both X2 and Ultra Tune?
Most people do not. Consider owning both only if you already use beauty devices consistently and can identify separate, non-overlapping jobs for each device.
Is Ultra Tune the same as a professional RF treatment?
No. Do not assume an at-home device delivers the same energy, protocol or results as an in-office medical procedure. Independent research supports home RF as a cosmetic device category, but outcomes depend on the device, protocol and user.
What if I have sensitive skin or a medical condition?
Start at a low intensity and follow the model-specific treatment zones and usage instructions.
For Ultra Tune 40.68, Medicube says to keep the device moving, avoid the Adam’s apple, eyelids and directly below the eyes, and reduce the intensity if the heat feels too strong or the skin becomes stressed.
If you have a medical condition, a recent cosmetic procedure, a history of significant skin reactions, or any uncertainty about whether RF or microcurrent is appropriate for you, review the current official manual and ask a qualified healthcare professional before use.
