The Medicube Age-R Booster Pro has amassed an ever-growing list of celebrity fans—including Hailey Bieber and nearly every member of the Kar-Jenner clan. Bieber, known for her signature glazed donut skin, doesn’t credit her glow solely to her peptide-packed Rhode lineup; she’s also loyal to this high-tech K-beauty gadget.

Vogue’s senior beauty shopping writer Kiana Murden was an early adopter of the Korean skincare brand’s first-gen model. “Is that the Medicube Age-R Booster-H?” she gasped while watching Bieber’s skin prep TikTok GRWM in 2023. Murden got the lowdown on the tool from chatting with dermatologist Dendy Engelman, who co-signed it, too. “I use it nightly for five minutes all over my face—super easy, painless, and efficient.”

The gadget has had its own glow-up in the past two years. “The main difference lies in evolution and performance.” Medicube’s Lyla Chang tells Vogue. “The Age-R Booster H was the first-generation device, offering a single specialized booster mode designed to increase skincare absorption by up to 490%—a streamlined option for anyone. The Age-R Booster Pro, on the other hand, takes things to the next level,” adding that the latest version is a four-in-one tool that blends the benefits of microcurrent devices and EMS (among others) into one compact device. Below, everything you need to know about the latest buzzy device—and if it really lives up to the hype.

About the Medicube Age-R Booster Pro

The Medicube Booster Pro is a 2.0 version of the Age-R Booster H. This “radiance device” aims to give your skin an at-home glow boost without needles or downtime. But how does it work? “Its upgraded Booster Mode builds directly on the original device, now delivering up to 785% enhanced absorption, along with stronger overall performance across all functions,” says Chang. “Instead of needing separate beauty devices to target separate skin concerns, the Pro features four advanced combines them all into one powerful, professional-grade tool.”

According to Medicube, this device doesn’t just make your products work harder—it makes your skin look better, too. “While many beauty tools rely on surface-level vibration or heat, the Booster Pro uses electroporation technology, which is gentle, low-frequency electrical currents that temporarily create micro-channels in the skin. This allows active ingredients to penetrate much deeper than they normally could,” says Chang. No, this isn’t wishful thinking, it’s a science-backed process. “The device increases product absorption by temporarily increasing the skin’s permeability, for better hydration, improved texture, and more noticeable results compared to applying products by hand,” explains board-certified dermatologist Dr. Dara Spearman, adding this pick can also boost circulation and encourage lymphatic drainage.

Even better? Its effects don’t vanish overnight. The brand claims increased ingredient absorption continues for up to 24 hours post-use, with long-term benefits—think firmer, brighter, healthier-looking skin—building with consistent use.

How to Use the Medicube Age-R Booster Pro

This device is designed to be used in the middle of your skin care regimen, as Bieber depicted in her TikTok. “After cleansing the face, you can apply your favorite skin care product all over the surface of the skin, select your method of choice, and use the device until your [product] is completely absorbed,” says Dr. Engelman. Its worth noting that the Air Shot mode, is the only option meant to be applied on clean, dry skin—otherwise, layer on your favorite formulas.
