Celebrities are known for their non-traditional skincare treatments. From diamond dust facials to $400 “Flash” treatments, we’ve seen it all. At least we thought we did until spotted Kate Hudson wearing “electro shock” under-eye patches again (we’ve seen her in them quite frequently) on Snapchat. But what do those wired white patches do? And are they safe? We tapped Jessica Weiser, MD, of New York Dermatology Group, for the lowdown on the star’s unusual beauty practice to get all the scoop.

Hudson, 37, recently documented her so-called “electro shock therapy,” wearing the white, wired patches (while driving), which wrapped around her ears and hung from a beeper-like plug, on Snapchat Monday morning.

“Note: Don’t wear these during traffic hours,” she wrote, adding, “Electro shock eye treatment complete.”

The actress’s under-eye masks, which looked less like a beauty treatment and more like an in-office experiment, are worn to deliver extra moisture to the skin to tighten fine lines and wrinkles, says Dr. Weiser.

“The product is an electric eye patch, which usually contains a combination of hyaluronic acid and collagen gels, among other ingredients,” Dr. Weiser tells PeopleStyle. “The patch is applied to the skin and then connected to an electrode to deliver heat energy to the underlying tissues and provide feedback to the device regarding skin temperature.”

She adds: “This precise temperature modulation can stimulate the epidermis and dermis, and some believe even the subcutaneous tissue layer,” Dr. Weiser says. “These electric eye patches are thought to stimulate collagen production, increase cell turnover and renewal, diminish the appearance of fine lines and reduce skin laxity to tighten the treated skin.”

But are these devices safe? According to Dr. Weiser, the jury is still out, as they are not yet FDA approved.

“This is not an FDA-approved device, so there is no proven efficacy or safety at this point,” she tells PeopleStyle. “Risk of burn would be the most serious concern, but also there is potential for many other side effects, including allergic contact reactions.”

So there you have it. If you’re dying to try out Hudson’s wired device to tighten those pesky crow’s feet, you may want to think twice before committing. It may not be worth the risk.
