This device’s six modes are primarily powered by microcurrents, or little electrical currents sent through the skin to stimulate the skin cells and facial muscles. “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.

Like version 1.0, the Medicube Booster Pro X2 combines that microcurrent technology with LED light, which “uses multiple wavelengths across the visible spectrum,” Mona Gohara, MD, a board-certified dermatologist in Hamden, Connecticut, told us earlier this year about the original device. “[That] may allow it to address a variety of skin concerns depending on the mode selected.”

Before we get into any more product details, know that the Booster Pro X2 isn't FDA-cleared—a designation that doesn’t mean a device actually works, but does affirm that it is similar enough to a product already cleared in the US to be considered safe. At the end of the day, FDA clearance doesn’t mean much, but some consumers feel better about investing in devices that have it. The first-generation Booster Pro doesn't have FDA clearance either.

How it’s different from the Medicube Booster Pro

Medicube has not come to play with this new and improved device. Our editors found that the original model was, let's say, intense. Cruel noted that a mid-level setting "had my muscles twitching (in a good way)," she says. Meanwhile, Allure commerce editor Sarah Han reported back: "The microcurrent mode is the strongest I've ever tried...I can literally see the muscles in my jawline being stimulated."

This next-gen device ups the ante—but to be fair, people asked for it. Medicube says customer feedback encouraged them to quite literally level it up: The Booster Pro X2 now has a sixth intensity level. You may be eager to crank it up, but the brand recommends starting at Level 1 for all modes, and I couldn’t agree more (I haven’t gone past Level 4 out of 6 despite pretty regular use).

The original device had four settings. Here’s a quick refresher:
