Key takeaways
- Home beauty devices operate at lower energy than professional treatments and work best for maintaining skin and addressing mild concerns over time, not delivering dramatic results.
- The four devices tested use different technology combinations, with clinical data showing results like 31.4% pore reduction and 24-hour hydration improvement depending on the mode.
- Pair these devices only with gentle, hydrating ingredients like hyaluronic acid and ceramides; strong actives like retinoids can increase irritation when penetration is enhanced.
- Skip at-home devices if you have sunburned skin, active eczema, open wounds, or recently had professional treatments; sensitive skin types should patch-test first.
Korean skincare brands lead in bringing advanced home-use technologies to market. The latest generation of handheld devices combines microcurrent, LED light therapy, electroporation, and electrical muscle stimulation (EMS) to boost radiance, improve firmness, reduce puffiness, and enhance product absorption. Before investing, understand what they can realistically deliver.
What Dermatologists Want You to Know
Home facial devices operate under safety constraints that professional in-office equipment doesn’t. According to Jane Yoo, MD, a dual board-certified dermatologist and Mohs surgeon based in New York City, “At-home devices can have a place in a skin-care routine, but they should not be compared directly to professional treatments.” They deliver lower energy than in-office versions, making them best for maintaining skin health and addressing mild concerns like dullness, puffiness, acne, and early aging signs over time—not for dramatic lifting or resurfacing.
None of these devices carry FDA clearance, though this doesn’t reflect poor performance; the FDA simply hasn’t evaluated them yet. Some consumers prefer FDA-cleared alternatives for added reassurance.
Medicube Age-R Booster Pro X2: Multitasking Power
The Medicube Age-R Booster Pro earned permanent spots in Allure editors’ routines. The newer Booster Pro X2 doubles the power and adds three new modes: Dual Mode (combining two treatments), Mask Mode (for sheet mask enhancement), and AI Mode (personalized routines via app). The device retains five core technologies: electroporation, electrical muscle stimulation (EMS), pore-targeting pulses, seven-color LED light, 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,” explained Marisa Garshick, MD, a board-certified dermatologist. Medicube tested the device through the Global Institute of Dermatological Sciences in South Korea using 20 to 22 participants per mode over 14- to 15-day periods. Air Shot reduced pore appearance by 31.4%; Microcurrent improved texture across forehead, smile, and eye lines; Booster mode increased hydration lasting up to 24 hours; and Derma Shot enhanced jawline, cheek, and under-eye definition.
Shanna Shipin, Allure’s senior commerce director, reported: “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).”
LG Pra.L Superform Galvanic Booster: Compact Design
At lipstick size and 1.7 ounces, the LG Pra.L suits travel routines. Its slim head glides around eyes, nose, and lips, working especially well for morning depuffing. The device delivers 8,500 vibrations per minute with a gentle galvanic current that helps water-based serums and moisturizers absorb better. It emits 630nm red LED light, linked to collagen support and fine-line softening.
Designer Briana Rengifo noticed results within a week: “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.” Slow, firm swiping motions worked best for puffiness. The main drawback: replaceable batteries instead of recharging.
Cellect Beauty Beam Rejuvenating Red: Targeted Light
The Cellect Beauty Beam delivers targeted red and near-infrared light across 625 to 850 nanometers, supporting collagen and softening fine lines, dullness, and firmness loss. “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, previously told Allure.
Senior staff writer Elizabeth Gulino used it 15 minutes per session, two or three times weekly: “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.” The rechargeable design and velvet pouch appealed to her, though an automatic timer would help signal when to move to the next area.
Centellian24 Madeca Prime Max: Simplified Automation
The Centellian24 Madeca Prime Max removes guesswork by offering three preset treatments: Brightening, Firming, and Absorption. Select your goal and the device automatically combines electroporation, microcurrent, EMS, and infrared light. LCD guidance and voice instructions walk through sessions; a Smart Skin Sensor activates the device only on skin contact.
Testing with the P&K Skin Clinical Research Center from April 15 to May 23, 2025, involved 21 women. Each mode showed temporary improvements in skin brightness and clarity, jawline firmness, and moisture absorption.
Editor in Chief Jessica Cruel described the effects: “You can feel the instant lymphatic drainage, especially when I go around my jawline. Immediately, you can see puffiness lessen. My favorite part is seeing my eyebrow jump when I focus on my eyes.”
Pairing Devices With Ingredients
The science behind booster devices rests on how they interact with the skin barrier. Dr. Yoo explains: “the evidence is still limited and depends heavily on the device, the technology, and the product being used with it.” One four-week study found medium-frequency EMS improved elasticity and jawline definition, though this doesn’t guarantee all booster devices meaningfully increase penetration across every formula.
Safe Ingredient Pairings
Pair these devices with “hyaluronic acid, glycerin, ceramides, panthenol, and other gentle, soothing ingredients,” according to Dr. Yoo. Avoid strong actives like retinoids and exfoliating acids unless your device specifically allows them and your skin tolerates the ingredient well. “If a device enhances the delivery of potentially irritating ingredients like retinoids or exfoliating acids, it could also increase redness, stinging, or barrier irritation,” Dr. Yoo cautions.
When to Avoid At-Home Devices
Contraindications and Skin Conditions
Skip at-home devices if you have sunburned skin, active eczema, open wounds, or if you’ve recently undergone professional treatments (unless your dermatologist approves). Avoid using them alongside retinoids, exfoliating acids, scrubs, or at-home microneedling.
Sensitive Skin Considerations
People with sensitive, rosacea-prone, or eczema-prone skin face higher risk of redness, stinging, dryness, or barrier irritation. “People with sensitive, rosacea-prone, or eczema-prone skin are more likely to experience redness, stinging, dryness, or barrier irritation from at-home devices,” Dr. Yoo says. If your skin barrier is already compromised, introducing a device may worsen irritation. A patch test on a small area before full-face use is prudent.

Frequently Asked Questions
Are Korean beauty devices FDA-approved?
None of the devices discussed here hold FDA clearance, though this doesn't reflect poor performance. The FDA simply hasn't evaluated them through its approval process yet. Some consumers prefer FDA-cleared alternatives for added reassurance.
How long do I need to use these devices to see results?
Results vary by device. The LG Pra.L showed plumping effects after one week of two-minute nightly use. The Cellect Beauty Beam requires 15 minutes, two or three times weekly, with gradual improvement in fine lines. The Medicube and Centellian24 are designed for daily five-minute sessions.
Can I use these with my retinoid routine?
No, unless your device instructions specifically allow it. Because these devices enhance product penetration, pairing them with strong actives like retinoids or exfoliating acids can increase redness, stinging, and barrier irritation. Stick with gentle, hydrating ingredients instead.
