The best Korean skin-care devices make it easier than ever to bring a little bit of K-beauty's buzziest technology, whether you're hoping to boost your glass glow , help your serums absorb more effectively, temporarily de-puff your face, or give your skin a firmer look between appointments. Today's most innovative devices combine technologies like microcurrent , LED light therapy , electroporation, and electrical muscle stimulation (EMS) into one handheld gadget, making them a multitasking addition to your routine.
That said, don't expect them to replace a dermatologist's office. " At-home devices can have a place in a skin-care routine, but they should not be compared directly to professional treatments," says Jane Yoo , MD, a dual board-certified dermatologist and Mohs surgeon based in New York City.
Because they're designed to be used safely without medical supervision, they operate at lower energy levels than in-office devices. That means they're best for maintaining results and tackling mild concerns like dullness, puffiness , acne , or early signs of aging over time—not delivering dramatic lifting or resurfacing in a single session.
One other thing to note: None of the devices on this list are FDA-cleared. That doesn't necessarily say anything about how well they work, but some shoppers appreciate the added reassurance that comes with an FDA-cleared device (which, in turn, just means the FDA has vetted and approved a device with comparable technology).
With realistic expectations in mind, these are the gadgets our editors are trying from K-beauty brands that have long been ahead of the curve when it comes to beauty innovation.
Allure senior commerce director Shanna Shipin using the Medicube Booster Pro X2
Why it's worth it: The Medicube Age-R Booster Pro already earned a permanent spot in our beauty routines as one of only four microcurrent devices our editors regularly use, so we were eager to see what the next-generation Booster Pro X2 could do. It keeps the five in-office-inspired technologies from the original, including electroporation to help skin care absorb more effectively, electrical muscle stimulation (EMS), pore-targeting electrical pulses, seven-color LED light therapy, and microcurrent.
"It is thought that since microcurrent has been shown to help wound healing and reduce inflammation, it may also promote collagen and elastin production to help firm and tighten the skin," Marisa Garshick , MD, a board-certified dermatologist in New York City, previously shared. The multitasking device temporarily boosts radiance, improves firmness, and sculpts the look of facial contours—all in just a few minutes a day.
The upgraded device builds on everything we loved about the original with a larger treatment head, twice the power, and three new modes: Dual Mode, which combines two treatments at once; Mask Mode, designed to enhance sheet mask absorption; and AI Mode, which creates personalized routines through the brand's app. With this lineup of features, it's hard not to ask: Is there anything this device doesn't do?
Tester feedback from senior commerce director Shanna Shipin
“I’ve been reaching for this streamlined, but seriously powerful tool more than any facial device I own (sorry, Shark CryoGlow , it was fun!). It’s not even because it’s more convenient; it isn’t, but if I put in five hands-on minutes, it gives me immediate results that are pretty on par with the clinical testing so far.
I simultaneously look more chiseled—particularly in the hollows of my face and jawline—and more voluminous in the cheekbones and my forehead (in a good way). It’s not unlike the fresh-faced results you get from a cryo tool , but so much faster and more effective.
The Medicube Booster Pro X2 also appears to leave my skin glowier; not exactly ‘glass’ but certainly happier and more hydrated (which I imagine has to do with the product penetration). I’ll need to test it for six months to report back on the long-term benefits, but in the interim, I’ve retired my other microcurrent devices.” —Shanna Shipin, senior commerce director
How the brand tested this product's efficacy
Medicube conducted testing through the Global Institute of Dermatological Sciences in South Korea. Clinical data were shared for four of the device's modes: Air Shot mode reduced the appearance of pores by 31.4%; Microcurrent mode improved skin texture across forehead lines, smile lines, and the eye area “for [a] healthy-looking bounce,” per the brand; Booster mode increased skin hydration, with benefits maintained for up to 24 hours; and Derma Shot mode improved facial definition along the jawline, cheeks, and under-eye area.
The studies were conducted over 14- to 15-day periods and included 20 to 22 participants.
Allure designer Briana Rengifo using the LG Pra.L Superform Galvanic Booster
Why it's worth it: Got a minute? That's all the time LG Pra.L Superform Galvanic Booster asks of you each day.
Not much bigger than lipstick tube, it has a slim treatment head that easily hugs the curves around your eyes, nose, and lips, making it especially satisfying for massaging away morning puffiness. It delivers 8,500 tiny vibrations per minute, while gentle galvanic current (a low-level electrical current) helps your favorite water-based serums and moisturizers sink in better (no special gels or specific skin care required).
The device also emits 630nm red LED light, a wavelength commonly used to support collagen production and soften the look of fine lines over time. And at just 1.7 ounces, it's light enough to toss in your makeup bag, making it an easy way to give your skin a little extra TLC whether you're at home or on the go.
Tester feedback from designer Briana Rengifo
"This little device made my skin-care routine feel so much more luxurious. I normally love the TheraFace Depuffing Wand , but it's a little bulky to travel with and the battery seems to run out much faster, so this feels like a great, more affordable alternative.
After just a week of using it at night for about two minutes, I noticed my skin looked immediately plumper and stayed hydrated longer. I especially loved the cool metal tip around my undereyes and cheeks, where my skin tends to be the driest.
I also found that using it in slow, firm swiping motions helped reduce puffiness. It's incredibly easy to use—it automatically turns on when it touches your skin.
My only complaint is that it runs on replaceable batteries instead of being rechargeable." —Briana Rengifo, designer
LG has not released comparable human clinical efficacy data. Its claims are based on established LED wavelengths—640nm red light for skin repair and collagen support—that have been evaluated in independent clinical studies .
Allure senior staff writer Elizabeth Gulino using the Cellect Beauty Beam Anti-Breakout Red
Why it's worth it: If you want the benefits of red light therapy without strapping on a full-face LED mask , the Cellect Beauty Beam Rejuvenating Red offers a more targeted approach. The slim, cordless device emits red and near-infrared light at wavelengths ranging from 625 to 850 nanometers to support collagen production and, with consistent use, help soften the look of fine lines, dullness, and loss of firmness.
“Red light is particularly effective for calming redness and reducing post-inflammatory erythema—the lingering red marks that can stick around long after a pimple is gone,” Lauren L. Levy , MD, a board-certified dermatologist based in New York City, previously told Allure .
It’s rechargeable and small enough to toss in your makeup bag, making it an especially handy alternative for anyone who doesn’t want to commit to a full-face LED mask .
Tester feedback from senior staff writer Elizabeth Gulino
“Cellect recommends using this device for 15 minutes each session, two or three times weekly, so that's exactly what I did. I have some fine lines around my eyes and am doing everything in my power to erase them.
Unlike an LED mask, I can get this tool close enough to my eyes without the light causing discomfort and have seen a slight improvement. I'll definitely need to use this for a longer period of time to see results, but I'm excited to use it more.
It's easy to use, easy to clean, and easy to stow away in its drawstring velvet pouch. Its small size makes it ideal for traveling, too, so there's no excuse for me missing a session. I've used a similar tool before that beeps after you've held it onto your skin for a certain amount of time and think this would benefit greatly from a feature like that!” —Elizabeth Gulino, senior staff writer
Cellect has not released comparable human clinical efficacy data. Its claims are based on established LED wavelengths—625–850nm red/near-infrared light for skin repair and collagen support—that have been evaluated in independent clinical studies .
Allure editor in chief Jessica Cruel using the Centellian24 Madeca Prime Max
Why it's worth it: If at-home facial devices feel more intimidating than inviting, the Centellian24 Madeca Prime Max is an easy place to start. Instead of asking you to choose between different technologies, it bundles them into three simple, goal-oriented treatments: Brightening, Firming, and Absorption.
Just pick the result you're after—whether that's a more radiant complexion, firmer-looking skin, or helping your favorite serum sink in better—and the device takes care of the rest by automatically combining modes like electroporation, microcurrent, EMS, and infrared light.
The Madeca Prime Max is just as beginner-friendly as it is multitasking. A built-in LCD screen and voice guidance walk you through every session, while a Smart Skin Sensor activates the device only when the treatment head touches your skin, so there's very little guesswork involved. It's the kind of beauty gadget that feels approachable—even for beginners.
Tester feedback from editor in chief Jessica Cruel
“I start the process by putting on my thickest serum or essence. I use the absorption setting.
There are five different levels, but I only go with the first. I start at my chin and sweep up my cheekbone.
Then, I do a few passes over my forehead before moving to the other side of my face. My favorite part is seeing my eyebrow jump when I focus on my eyes.
You can feel the instant lymphatic drainage, especially when I go around my jawline. Immediately, you can see puffiness lessen.
I like that this comes with a cap to go over the tip for sanitary reasons. It leaves skin glowy but it really depends on the product you use.
It reminds me a lot of the Medicube Age-R Booster Pro .” —Jessica Cruel, editor in chief
According to the brand, the Madeca Prime Max was evaluated in a human clinical study conducted by the P&K Skin Clinical Research Center, an independent testing laboratory in South Korea. The study included 21 adult women and ran from April 15 to May 23, 2025. The brand tested each of the device's three modes and reported temporary improvements in skin brightness and clarity, jawline firmness, and moisture absorption.
Many of today's Korean skin-care tools combine multiple technologies into a single device, but each one serves a different purpose. Here's what to know:
As with any at-home beauty device, it's important to keep expectations in check. Because they're designed to be used safely without medical supervision, they operate at lower energy levels than professional treatments. “They're best for maintaining results and addressing mild concerns over time—not replacing in-office procedures when you're looking for significant lifting, resurfacing, or collagen remodeling,” says Dr. Yoo.
Korean beauty tools can be safe for sensitive skin, but if your skin is easily irritated, it's worth proceeding with caution. “People with sensitive, rosacea -prone, or eczema -prone skin are more likely to experience redness, stinging, dryness, or barrier irritation from at-home devices,” says Dr. Yoo.
She recommends avoiding them altogether if you have sunburned skin, active eczema, open wounds, or immediately after in-office treatments (unless your dermatologist says otherwise). “It's also smart to skip using them alongside potentially irritating ingredients like retinoids , exfoliating acids, scrubs, or at-home microneedling,” she says. If your skin barrier is already compromised, adding a device may only make irritation worse.
Hydrating and barrier-supportive ingredients are generally the safest choices to pair with booster devices, says Dr. Yoo. She recommends formulas containing “hyaluronic acid, glycerin, ceramides, panthenol, and other gentle, soothing ingredients.” On the other hand, strong actives should be avoided unless the device instructions specifically allow them and your skin already tolerates that ingredient well.
There is some scientific rationale behind booster devices, because the skin's outermost layer is designed to act as a barrier, and certain technologies may temporarily affect how products sit on or move through the skin, says Dr. Yoo.
That said, "the evidence is still limited and depends heavily on the device, the technology, and the product being used with it," she says. For example, one small four-week study found that a medium-frequency EMS device used improved skin elasticity, sagging, and double-chin lifting compared with the skin-care product alone.
However, she notes that this doesn't prove all booster devices meaningfully increase ingredient penetration—or that they'll work the same way with every formula, says Dr.Yoo. She also cautions that more penetration isn't always better: “If a device enhances the delivery of potentially irritating ingredients like retinoids or exfoliating acids, it could also increase redness, stinging, or barrier irritation,” she says.
For that reason, she recommends sticking with gentle hydrators and barrier-supporting ingredients when using at-home booster devices.
When Allure tests a product , our editors look at it from every angle in an effort to best serve you. We are particularly discerning when writing about skin-care devices. This is because of the increased risks and, in many cases, the high price points that accompany at-home dermatological tools and devices.
Each device undergoes extensive testing and must be approved by a senior member of our beauty team prior to appearing in Allure . Additionally, our editorial team consults board-certified dermatologists and cosmetic chemists about the science behind product claims and independently reviews any studies cited by brands.
Testers consider performance across four primary categories: efficacy, safety (including ease of use), research and the science behind specific claims, as well as product value. To learn more information on what's involved in our reporting, check out our complete reviews process and methodology page .
A beauty product is a personal purchase. You might be searching for a face cream to address persistent dryness or a new nail product to add to your Sunday self-care routine; you may simply be browsing around for the latest launches to hit the hair market.
No matter what you seek or your individual needs and concerns, Allure wants to ensure that you love anything we recommend in our stories. We believe that having a diverse team of writers and editors—in addition to the wide range of outside testers and industry experts we regularly call upon—is essential to reaching that goal.
After all, can we really say a skin-care product is the "best" for people over 50 if the only testers we've solicited opinions from folks who have yet to hit 30? Can we honestly deem a high-end diffuser worthy of your hard-earned cash if it’s never been tested on curls?
We're proud that our staff spans a wide range of ages, skin tones, hair textures, genders, and backgrounds, which means that we are able to fairly assess any beauty product that comes into the beauty closet.
