If you're comparing the Nu Skin RenuSpa iO and the NuFACE Trinity, you're looking at two microcurrent devices built for different jobs, with different target areas and different routines.
This comparison is written by NuBodyRx. We sell the RenuSpa iO, so take the source into account. What follows is what each device is designed to do, in each manufacturer's own terms.

The Core Difference: One Area or Two
This is the distinction that makes the comparison less of a head-to-head and more of a question about what you want to treat.
The NuFACE Trinity is a facial microcurrent device, designed to tone and lift the muscles of the face — jawline, cheeks, brow — through two spherical conductors. It is FDA-cleared for facial toning. If your concern is the face and only the face, that is what it is built for.
The Nu Skin RenuSpa iO covers both face and body. Nu Skin describes it as “Nu Skin's first fully integrated wellness and beauty system, delivering a comfortable and soothing massage while also helping visibly tone, sculpt, and firm skin.” Nu Skin's own study used the body sites — arms, thighs/buttocks and abdomen.
Bottom line: these devices don't really compete. If you only want facial toning, the NuFACE is a facial device with FDA clearance. If you want one device that also covers the body, that is the RenuSpa iO's remit.
Nu Skin RenuSpa iO: What Nu Skin Says
Nu Skin's stated benefits for the RenuSpa iO:
- “Visibly depuffs, contours, tones, and sculpts and reduces the appearance of dimples through skin stimulation.”
- “Helps energize and depuff the skin's appearance through skin stimulation.”
- “Visibly firms and tightens skin for a more youthful appearance.”
- “Provides a smooth, comfortable massage while contributing to skin stimulation.”
Nu Skin reports the following from a 12-week study of Nu Skin® RenuSpa iO™ + Conductive Gel, as composite results across body sites (arms, thighs/buttocks and abdomen): a 61% improvement in skin hydration, a 34% improvement in skin tonicity, and an 18% improvement in skin overall appearance.
The technology is Adaptive Microcurrent Technology, which Nu Skin describes as patent-pending and as something that “comfortably adjusts to your skin in real time.”
NuFACE Trinity: What Makes It Different
The NuFACE Trinity's distinguishing feature is its FDA clearance for facial toning and its modular attachment system — the ELE attachment for the eye and lip area, and the Trinity+ upgrade. It is a facial device, and it does not treat the body.
