THOME The Glow review: the short verdict

THOME The Glow Signature is a well-documented, mid-priced ultrasound handheld. It uses 3 MHz and 10 MHz, publishes the timing of each of its three modes, and talks you through a 12-minute session. It’s a good fit if you want structure and a price between $299 and $399. The trade-offs: two frequencies rather than four, a routine built around THOME’s ampoules, and evidence that comes from a brand-run study. Like every device in this category, it’s Class I listed, not FDA-cleared.

The three modes explained

Every mode lasts 12 minutes and finishes on 3 MHz and 10 MHz together. What changes is the first half:

  • Focus starts with 10 MHz alone for six minutes. 10 MHz is the higher of the two frequencies, so it acts closer to the surface.
  • Tension starts with 3 MHz alone for six minutes. The lower frequency reaches further into the skin (StatPearls).
  • Inner runs 3 + 10 MHz together for the full 12 minutes.

That transparency is a point in THOME’s favor: many devices say “multi-frequency” without numbers. What The Glow lacks is a very low (1 MHz) or very high (19 MHz) setting, which four-frequency devices such as the Quadthera Titan add. No study shows whether that changes visible results.

How to use THOME The Glow

  1. Cleanse, then apply a THOME Boost Ampoule (or the water-based layer your manual allows).
  2. Turn it on, then press once to cycle through Focus, Inner and Tension (per THOME’s how-to steps).
  3. Set intensity with the triangle button on the back of the head. THOME recommends Level 1 for beginners.
  4. Glide slowly in upward motions, following the voice prompts for each area. The session ends after 12 minutes.

THOME’s FAQ describes the feeling as warm and soothing and says daily use is fine. Keep it off broken or irritated skin, and check with a clinician first if you’re pregnant or have an implanted device. Our ultrasound explainer covers general safety.

Ampoules and running costs

THOME sells five Boost Ampoules (Hyaluron, PDRN, Exosome, Peptide and Niacinamide) at $22.90 each, and a Complete Ampoule Set that was $368.60 on sale ($490.60 regular) when we checked. The brand’s own study used the Collagen Boost Ampoule. Factor ampoules into the real cost if you plan to follow THOME’s routine exactly. If you’d rather use a plain conductive gel, check the manual first; our conductive gel guide explains what to look for.

What the evidence shows

THOME reports results from testing by ACE Skin Lab on 22 women between December 4, 2025 and January 2, 2026, using The Glow with THOME’s Collagen Boost Ampoule. Among the brand-reported figures: a 251% improvement in radiance after one use, 122.9% for elasticity, 55.4% for firmness and 36.4% for signs of aging. THOME also reports a skin irritation test on 32 adults with a score of 0.00.

Read these as brand claims. The study is small, combines device and ampoule, and isn’t peer-reviewed or sham-controlled as far as we could find. Independent research on non-focused home ultrasound is limited; a 2026 review of at-home skin devices describes their efficacy as “modest” and more gradual than in-office treatment (Layne & Weiser 2026).

FDA status and who makes it

FDA’s registration and listing database shows THOME THE GLOW SIGNATURE, THOME TWENTY UP and THOME THE GLOW PRO under EASYTEM Co., Ltd. in Korea, product code ISA (“massager, therapeutic, electric”), a Class I category exempt from premarket review. EASYTEM’s listing also includes devices sold under several other brand names. So The Glow is Class I listed, not FDA-cleared, the same status as most handheld ultrasound devices. Our FDA labels guide explains why that distinction matters.

Price and where to buy

On October 8, 2026, THOME’s US store listed The Glow Signature at $399, alongside a separate sale listing at $329, and Olive Young US had it at $299. THOME also runs email-signup promotions. Both THOME and Olive Young only accept change-of-mind returns on unopened, unused items within 30 days, with the buyer paying return shipping.

Frequently asked questions

Is THOME The Glow worth it?
For a mid-range budget, it’s one of the better-documented ultrasound handhelds: clear frequencies (3 + 10 MHz), three modes with published timings and voice guidance. Its evidence is a brand-run study with THOME’s own ampoule, so expect subtle, gradual changes rather than proven results.
What does THOME The Glow do?
It sends low-intensity, non-focused ultrasound at 3 MHz and 10 MHz into the skin through an ampoule or gel layer. THOME markets it for radiance, elasticity, firmness and hydration. It isn’t a HIFU or Ultherapy-style lifting device.
How often should I use THOME The Glow?
THOME’s FAQ says it can be used daily, with one 12-minute guided session. Start at Level 1, glide slowly upward, and reduce frequency if your skin feels irritated.
Do I have to use THOME ampoules?
THOME recommends its Boost Ampoules ($22.90 each). Ultrasound needs a water-based layer to transmit energy, so whatever you use should be a water-based gel or serum rather than oil. Check THOME’s manual before substituting.
Is THOME The Glow FDA-approved?
No. The Glow Signature is Class I listed in FDA’s registration and listing database under product code ISA (“massager, therapeutic, electric”), via the Korean manufacturer EASYTEM Co., Ltd. Listing isn’t FDA clearance or approval.
THOME The Glow vs Twenty Up: which should I buy?
Both use 3 + 10 MHz. The Glow Signature has three modes (Focus, Inner, Tension) aimed at radiance and firmness; Twenty Up has two modes and is positioned for texture and blemish-prone skin at a lower $249 list price.
Where can I buy THOME The Glow in the US?
From THOME’s US store and from Olive Young US. On October 8, 2026, THOME listed it at $399 (with a separate $329 sale listing) and Olive Young US at $299.
