glow.m vs THOME: Cryo Sonic Pro, Booster Sonic, The Glow and Twenty Up Compared
glow.m and THOME are two of the best-known Korean ultrasound brands sold in the US. Here’s how their devices compare on frequencies, modes, build, gel, FDA status and price, and where the Quadthera Titan fits.
glow.m vs THOME: the short verdict
On published specs, glow.m’s Cryo Sonic Pro beats THOME The Glow on range (1, 3, 10 and 19 MHz vs 3 + 10 MHz) and adds a titanium head and cooling, while THOME The Glow wins on guidance with a voice-led 12-minute routine at a lower list price ($399 vs $755 sale). At the budget end, glow.m’s Booster Sonic ($299 sale) and THOME’s Twenty Up ($249) both use 3 and 10 MHz. Our overall pick across all three brands is the Quadthera Titan ($1,100 with gel): four frequencies, a Titanium Grade 2 head, a patented piezoelectric motor (per Quadthera) and any water-based gel. All of these devices are Class I listed, not FDA-cleared.
We haven’t tested these devices hands-on. This comparison uses each brand’s product pages and prices seen on October 24, 2026, plus FDA’s database. For the full category, see the best at-home ultrasound device for face; for THOME in depth, our THOME The Glow review and Quadthera Titan vs THOME.

Frequencies and modes
All of these are low-intensity, non-focused ultrasound devices. Higher frequencies are absorbed closer to the surface and lower ones reach further (StatPearls), so four-frequency devices cover more depth bands. glow.m’s Cryo Sonic Pro and the Quadthera Titan both list 1, 3, 10 and 19 MHz and publish which frequencies each mode uses. THOME uses 3 and 10 MHz and sequences them differently in each mode: Focus starts at 10 MHz, Tension at 3 MHz, and all three finish on both combined. No published study compares these combinations head to head.
Build and head material
glow.m says the Cryo Sonic Pro has “a titanium head” without giving a grade; its Booster Sonic page doesn’t state a material. THOME’s product pages don’t state a head material or transducer type. Quadthera lists a Titanium Grade 2 transducer head for the Titan, which it says it chose for acoustic conductivity and a skin-friendly surface, and a piezoelectric ceramic motor it lists as patented; its maker, ECO DM LAB, covers the multi-frequency probe with Korean patent 10-2420176 (KR 10-2420176 B1).
Routine, gel and running costs
- glow.m: both devices come with a 100 g Moisture Booster Gel; refills were $18.99 on sale ($30 regular). The Cryo Sonic Pro has a 9-minute auto-off and three levels.
- THOME: one 12-minute voice-guided session; THOME recommends its Boost Ampoules at $22.90 each.
- Quadthera Titan: up to 10 minutes with auto-off; Quadthera says any water-based conductive gel works, so ongoing costs can stay low.
Brand studies
Each brand cites its own testing. THOME reports results from an ACE Skin Lab study of The Glow with its Collagen Boost Ampoule (22 women, December 2025 to January 2026). glow.m says its Booster Sonic with Moisture Booster Gel “boosted skin hydration by 81% after just one use” in a clinical test; we haven’t seen the study. Quadthera publishes a 4-week P&K Skin Research Center study of the Titan (20 people, commissioned by Quadthera) reporting +32.2% surface firmness and +49.3% visible skin density (Quadthera results). Different labs, products and measures mean the numbers aren’t directly comparable. What the wider evidence does and doesn’t show: does at-home ultrasound work?
