Ultrasound vs Microcurrent: Which At-Home Face Device Fits You?
Microcurrent devices pass a small electrical current through the skin; at-home ultrasound devices vibrate at megahertz frequencies with no current at all. Here’s how they differ in feel, gel, evidence and FDA status, and who each suits.
The short answer
Choose ultrasound if you want to avoid electrical current; choose microcurrent if FDA clearance matters most. Microcurrent (NuFACE, ZIIP) has FDA-cleared models, but limited published evidence and temporary reported effects, and it isn’t for people with pacemakers. At-home ultrasound (Quadthera, THOME, glow.m) is usually felt as nothing or slight warmth; those devices are Class I listed, not FDA-cleared, and their device data is mostly brand-run. If you go ultrasound, our pick is the Quadthera Titan (1, 3, 10 and 19 MHz, $1,100 with gel).

Ultrasound vs microcurrent, side by side
| Ultrasound | Microcurrent | Edge | |
|---|---|---|---|
| What it uses | Megahertz sound waves (1 to 19 MHz on current devices) from a vibrating head | A low-level electrical current between two contact points | Different by design |
| What you feel | Usually nothing, or slight warmth | Can tingle, especially when the gel runs thin | Ultrasound, if you dislike current |
| Gel | Needs a water-based layer (gel or serum) | Needs a conductive gel, often the brand’s own | Tie |
| Evidence | Mechanism well studied in medicine; device data mostly brand-run | Limited published evidence; reported effects are temporary | Neither is strong |
| FDA status | Class I listed (product code ISA); not FDA-cleared | Some models FDA-cleared (NuFACE Mini K191672, TRINITY+ K201782) | Microcurrent |
| Who should skip it | Check the manual; avoid broken or irritated skin | Pacemakers, implanted electronics, serious heart conditions, pregnancy | Ultrasound has fewer listed exclusions |
| Example devices | Quadthera Titan, THOME The Glow, glow.m | NuFACE MINI+, NuFACE TRINITY+, ZIIP HALO | — |

How they differ
Energy. Microcurrent devices send a low-level current between two contact points. Ultrasound devices use a piezoelectric element to vibrate the head at megahertz frequencies. Ultrasound’s physics is well studied in medicine; how much an at-home device does for skin is less clear. More in does at-home ultrasound work?
Feel. Microcurrent can tingle, especially when the gel layer runs thin. Ultrasound typically feels like nothing, or slight warmth.
Evidence. Microcurrent’s published evidence is limited and reported effects are temporary. At-home ultrasound data is mostly brand-run; for example, Quadthera publishes a 4-week P&K Skin Research Center study of 20 people that Quadthera commissioned. Neither category has large independent trials for these devices.
FDA status. Several microcurrent devices are FDA-cleared through 510(k): the NuFACE Mini (K191672) and TRINITY+ (K201782), for example. The at-home ultrasound devices we’ve checked are Class I listed (ISA), which is a registration, not clearance.
Who each suits
- Ultrasound suits people who don’t want current on their face, who have a pacemaker or other implanted electronics (microcurrent is ruled out; check the ultrasound manual too), or who already use a serum routine.
- Microcurrent suits people who want a device with an FDA clearance they can look up, and who don’t mind a brand-specific gel.
