What an ultrasonic skin scrubber does

A skin scrubber vibrates a thin metal blade very fast. On wet skin, the vibration and water loosen surface oil, debris and dead cells, which you see collect on the blade. Dermatologist Michele Green told Vogue these devices typically run at 20,000–30,000 Hz and help decongest pores “without the harshness or trauma associated with physical scrubs or manual extractions” (Vogue). Dermatologist Scott Paviol told Byrdie they suit people who don’t tolerate scrubs, brushes or peels, including sensitive, rosacea-prone and acne-prone skin types (Byrdie).

A typical example is the dermaflash DERMAPORE+ ($109). dermaflash says it runs at 35 kHz, adds an “ionic” charge to the blade, and has two modes: Extract (blade tip angled on wet skin) and Infuse (flat side over your serum). It comes with a 0.5 fl oz Prep Mist. Its “97% had a significant reduction in pore size” figure comes from brand testing measured immediately after one use, so read it as a short-term effect (dermaflash).

What an ultrasound facial device does

An ultrasound facial device uses a transducer to send megahertz-range ultrasound into the skin through a layer of gel or serum, which is needed because ultrasound doesn’t travel well through air. You glide it slowly over the face for several minutes. Brands sell them for skincare absorption, firmness and glow; the evidence for those claims is mostly small, brand-run studies, which we cover in what at-home ultrasound skincare is (and isn’t). They are not HIFU: home devices use low-intensity, non-focused ultrasound, not the focused energy of clinic treatments such as Ultherapy (see HIFU vs Ultherapy).

Examples range from THOME The Glow (3 and 10 MHz, $399 list; our review) to the Quadthera Titan† (1, 3, 10 and 19 MHz, $1,100; our review). Compare them all in the best at-home ultrasonic facial devices.

Why kHz vs MHz matters

Ultrasound means sound above about 20 kHz, so both tools qualify. The difference is scale: 1 MHz is 1,000 kHz, so even the Titan’s lowest setting is about 29 times the 35 kHz frequency of DERMAPORE+. Two practical consequences:

• Different targets. A scrubber’s blade works mechanically at the surface with water. Megahertz devices are designed to deliver energy into the skin through gel, and in general higher frequencies act more superficially and lower ones reach deeper, which is why multi-frequency devices offer several settings.
• The “absorption” science points both ways. The strongest skin-permeability effects in drug-delivery research come from low-frequency ultrasound below 100 kHz (Mitragotri & Kost, 2004). That research used lab equipment and set-ups unlike either consumer tool, so it doesn’t prove that a $40 spatula or a $1,100 device boosts your serum by a meaningful amount.

Which should you buy?

• Buy a skin scrubber if your main goals are congested pores, blackheads on the nose and chin, and a gentle alternative to scrubs and peels, on a budget.
• Buy an ultrasound facial device if you want a gentle, barely felt anti-aging routine to use most days with your serums, and you’re comfortable paying more for gradual, modest changes.
• Neither, if your priority is wrinkles with the strongest evidence: look at FDA-cleared LED masks.

How to use an ultrasonic skin scrubber safely

1. Cleanse, then keep your skin wet the whole time (water, a facial mist or cleanser). Using it on dry skin increases friction and irritation, Dr. Green told Vogue.
2. Hold the blade at the angle your manual specifies (dermaflash says about 45°, tip pointing down, for Extract mode) and glide it lightly; don’t press.
3. Wipe the blade as debris collects.
4. Follow with serum, using the infuse mode if your scrubber has one, then moisturizer.
5. Limit it to two to three times a week (Byrdie’s dermatologists). Skip active or inflamed acne, wounds, sunburn and healing skin (Vogue; dermaflash).
