Kim Kardashian Loves This Viral K-Beauty Device, and It’s 20-Percent Off Through Tonight

Blend some jaw-dropping Amazon Prime deals with the hottest K-beauty trends and you have a near-guaranteed must-buy. Add Kim Kardashian to the mix, and you have medicube.

The Korean skin-care brand behind one of the most talked-about at-home device lines in beauty right now just got a high-profile co-sign from Kardashian herself. In a recent Instagram Reel, she’s shown using the medicube Booster Pro X2 ($239, originally $299), the brand’s newest at-home device, alongside the medicube NAD EGF Firming Serum ($15, originally $22).

The timing couldn’t be better: The device is 20-percent off for Amazon Prime Day—dropping from $299 to $239—but time is ticking, as the sale ends tonight at 11:59 p.m. PDT.

According to the brand, the Booster Pro X2 is a significant upgrade from the original. Where the first generation offered four treatment modes, medicube says the X2 expands to seven—adding Dual Mode (which lets you combine two technologies in one session), Mask Mode (designed for use over sheet masks to boost essence absorption) and an AI Mode that connects to the AGE-R app to recommend personalized routines based on your skin concerns, available time and usage history.

Per the brand, the treatment head is 1.3x larger for more efficient coverage, and intensity goes up to Level 6, one step beyond the original’s Level 5.

The device is designed to target product absorption, pore appearance, firmness, elasticity and radiance—and through the app, users can save customized routines, track usage and receive AI-guided recommendations. It’s the kind of connected beauty-tech experience that makes a $299 device feel like less of a leap and more like a smart buy.
