For decades, microcurrent has been used in different frequencies and waveforms to treat everything from wounds to migraines to chronic pain. Professional athletes and anyone who has had physical therapy have often experienced an electrostim machine, as orthopedists routinely prescribe microcurrent to aid in the repair of ligaments and muscles.
On a muscular level, the microcurrent acts like a personal trainer to tone and shorten muscle fibers. On a dermal level, as Pugliese, the skin physiologist, notes, there is serious anti-aging action going on. Pugliese has spent more than five years analyzing microcurrent's effect on fibroblasts by biopsying skin before and in between microcurrent treatments, and has found a statistically significant increase not only in the production of collagen and elastin, the skin's main structural proteins, which degrade with age, but in that of glycosaminoglycans, or "GAGs," the viscous material in which the proteins are embedded. "When you see a nice plump cheek like a baby's and you pinch it and it feels very good and snappy," he says, "that's GAGs." And, according to Perricone, the long-term benefits are more than skin-deep: If you have a microstimulation machine, "you don't have to have perfect genes," Perricone says. "When I first started working with celebrities, I assumed they were genetically gifted and had perfect symmetry." But now he knows that symmetry can be made: "Not only can we use electrostim to increase our muscle mass, we can accentuate one side of the face by working it harder than the other to give a more symmetrical appearance."
Electric facials are on the menu everywhere from Perricone's New York flagship spa to Four Seasons hotels to Elizabeth Arden's Red Door salons. Professional-grade microcurrent machines emit a positive and a negative current via two wands, probes, or sponges. When the probes are placed a few inches apart on the face, a circuit of current travels from one point to the other and "stimulates" the tissue in between, Perricone says. The current is subsensory, which means all one feels is the gliding of the rods and perhaps a slight tingle. Customers often fall asleep midfacial. The other option is to DIY with an at-home device. Suzanne Somers teamed up with engineer Rodger Mohme, who previously led the team at Apple to shrink a desktop computer down to laptop size, to create the FaceMaster, a vanity-table version of a large in-spa machine. The only handheld microcurrent device with FDA approval is the NuFACE, created by Carol Cole, a SoCal facialist who got tired of lugging her gigantic machine up into the Hollywood Hills. It emits the same level of current as a pro machine (you can get a 30-minute poolside NuFACE treatment at the Four Seasons Maui for $125), but the micro-amps deliver via two fixed metal probes.
ELLE editors tested both the FaceMaster and NuFACE in our offices and found they instantly increased circulation for that glowy, plump-but-not-puffy look that lasted for a few hours. But, in our untrained hands, the DIY could not provide microcurrents' more sophisticated, bespoke effects. With the right expertise, microcurrent can be used to dramatically, if temporarily, shape the face. It's no wonder celebrities have become insatiable consumers of electric facials, especially during awards season. "The pop lasts for about five hours," says facialist Melanie Simon, whose skin-care company, Circ-Cell, is partially backed by Lynn Harless, aka Justin Timberlake's mom. Madonna and Kate Winslet are outspoken fans of Tracie Martyn's trademarked Red Carpet Facial, a proprietary treatment that incorporates mild electrical current. Regular microcurrent sessions were rumored to be Princess Di's beauty secret. And according to an industry source, J.Lo just spent $22,900 on her own professional-grade CACI Ultra (no word on whether she's administering them herself).
Depending on where the probes are placed, either above the origin or insertion point of a muscle, and how many seconds they're held there, users can smooth a furrowed area by stretching the muscle or add lift by shortening the muscle. "If you lift from the cheekbones toward the hairline, it will make your eyes more almond shaped," says makeup artist Kristin Hilton, who travels between New York and L.A. to work on clients including Uma Thurman and Milla Jovovich. "You can even create an arch in the eyebrows." Hilton keeps NuFACE in her makeup kit so she can "sculpt and lift" before she applies a client's makeup. "I'm a skeptical person," Hilton says. "For me to like something like this is unusual. But I use it for five minutes on each side, pulling upward. Everything's tighter. You look more awake. People know something's different, but they don't know what. Usually they say, `Did you get your hair cut?'"
The exact protocol for combining Botox and microcurrent has yet to be written, but most proponents agree to wait a few weeks post-injection before getting a facial. According to Charles Boyd, MD, a plastic surgeon with practices in Michigan and New York, "In the first 24 hours after an injection, you could potentially move the Botox from a muscle where you injected it into a muscle you did not intend," he says. "That doesn't mean it's going to move from your forehead to your neck, but maybe from your eyebrow to your upper eyelid." Simon's clients wait two weeks post-Botox for an electric facial, then return for monthly follow-ups (per skin's renewal cycle, which is 28 days). "Botox and electric facials are great companions. I could spend hours smoothing lines out and then my clients will walk out the door and make the expression that caused the wrinkle 1,000 times that night," Simon says. "Botox is very efficient at knocking out expression wrinkles. Electric current fixes everything else—it's the cherry on top."
