"HIFU" describes a technology category, not a specific device. Within that category, three platforms account for most legitimate clinical use globally: Ulthera (also marketed as Ultherapy, made by Merz Aesthetics), Ultraformer III (made by Classys), and Doublo (made by Hironic). All three are FDA-cleared or have equivalent international clearances. All three deliver focused ultrasound to the SMAS layer at 4.5 mm and to dermis at 3 mm. They are competitively priced, broadly equivalent in clinical outcome, and choosing between them is more about clinic preference and protocol fit than about one device being clearly superior. This guide compares the three on technology, treatment time, patient experience, and clinical results.
The three real platforms
Ulthera / Ultherapy (Merz Aesthetics, USA)
- FDA-cleared 2009 (the first HIFU platform to receive FDA clearance)
- Unique feature: real-time ultrasound visualization during treatment — operator sees the tissue layer being treated before each pulse
- Depths: 1.5 mm, 3 mm, 4.5 mm
- Single transducer per cartridge type, with multiple cartridges used per treatment session
- Treatment time: 60–90 minutes for full face
- Strong clinical evidence base — most-published HIFU platform
- Premium price tier in most markets
Ultraformer III (Classys, South Korea)
- KFDA-cleared 2014, CE marked, available in most international markets
- Faster pulse delivery than Ulthera — sessions are typically 30–45 minutes shorter for equivalent coverage
- Depths: 1.5 mm, 3 mm, 4.5 mm, 6 mm, 9 mm, 13 mm (the body-depth options are an Ultraformer strength)
- Multi-cartridge transducer system; technician switches cartridges by depth
- MMFU technology (micro and macro focused ultrasound) — slightly different beam profile than Ulthera
- Strong body-treatment capability due to deeper depth options
- Mid-tier pricing in most markets
Doublo (Hironic, South Korea)
- KFDA-cleared, available in international markets
- Depths: 1.5 mm, 3 mm, 4.5 mm
- Different cartridge architecture — competitively priced consumables
- Treatment time: 45–60 minutes for full face
- Mid-tier pricing in most markets
Side-by-side comparison
| Feature | Ulthera | Ultraformer III | Doublo |
|---|---|---|---|
| FDA clearance | Yes (2009) | CE/KFDA | KFDA |
| Maximum facial depth | 4.5 mm | 4.5 mm | 4.5 mm |
| Body depths | 13 mm available | 6, 9, 13 mm | Limited body |
| Real-time imaging | Yes | No | No |
| Session time (full face) | 60–90 min | 30–60 min | 45–60 min |
| Per-session cost (typical) | Highest tier | Mid-tier | Mid-tier |
| Clinical evidence base | Strongest | Strong | Moderate |
Where each has the edge
Ulthera/Ultherapy strengths:
- Real-time ultrasound visualization — the operator sees exactly which tissue layer they are treating before each pulse
- Strongest clinical evidence base, with the longest history of peer-reviewed publication
- The "premium" choice in many markets — a useful signal of clinic positioning when verifying device authenticity
Ultraformer III strengths:
- Faster sessions — particularly valuable for patients with limited tolerance for long procedures
- Best-in-class body protocols due to deeper depth options (6 mm, 9 mm, 13 mm)
- Strong international adoption — widely available outside the US
Doublo strengths:
- Cost-effective consumables, which translates to lower per-session pricing
- Comparable clinical results for facial protocols
- Strong adoption in Asian and Latin American markets
Clinical outcome comparison
The honest framing: clinical outcomes from all three platforms are comparable when the operator is experienced and the protocol is appropriately designed. Differences in cartridge architecture and pulse delivery produce minor variations in patient experience (session time, comfort) but the SMAS-layer collagen response is similar.
The bigger variable in HIFU outcomes is not the device brand but: operator experience, energy selection, treatment density, and patient-specific factors (skin type, severity of laxity, age). A skilled operator on Doublo will produce better results than an inexperienced operator on Ulthera.
What matters more than the brand
- Is the device genuine? Real Ulthera, Ultraformer, or Doublo — not a Chinese 7D HIFU clone. We address verification in our dedicated post on real vs imitation.
- Operator experience. Ask how many HIFU sessions the operator has performed. Hundreds is the threshold for fluency.
- Anesthesia infrastructure. Can the clinic deliver full-energy SMAS protocols comfortably?
- Pre- and post-treatment protocols. Skincare prep, sun avoidance, and aftercare matter as much as the device.
Why Elyzea is different in Lima
Three things separate Elyzea from most "HIFU" providers operating in Lima and across Latin America:
- A real HIFU platform — not a Chinese "7D HIFU" knockoff. Genuine HIFU devices deliver focused ultrasound to the SMAS layer at 4.5 mm with calibrated, predictable energy.
- An MD anesthesiologist on-site. HIFU at SMAS depth is genuinely painful; on-site anesthesia means we can run full energy comfortably.
- A full clinical setup with a recovery room. Treatment room, anesthesia bay, dispensary, and a private rest area — not a single-bed spa room.
Pricing context
Per the Elyzea price list (prices.md), HIFU is S/1,000 (~US$286) full face, S/1,500 (~US$429) face + neck. The pricing reflects the genuine HIFU platform, anesthesia infrastructure, and full clinical setup. Compared to US clinics where Ulthera sessions run US$3,000–6,000, Lima delivers genuine HIFU at one-tenth the per-session cost.
FAQ
Should I insist on Ulthera specifically?
If you have access to Ulthera and prefer the real-time visualization feature, it is a reasonable preference. For most patients, the equivalent results from Ultraformer III or Doublo at potentially lower cost are practically equivalent.
How can I tell which platform a clinic uses?
Ask directly. A clinic running real equipment is happy to identify the brand and model. A clinic running a Chinese clone will deflect or use generic terminology like "HIFU machine" without specifying.
Are the consumables (cartridges) interchangeable?
No. Each platform has its own proprietary cartridge architecture. Real Ulthera cartridges only work in Ulthera units; same for Ultraformer and Doublo. Cross-compatibility doesn't exist.
Practical implications for patients
For a patient evaluating clinic options, the practical takeaways:
- Real platform first. Ulthera, Ultraformer III, or Doublo — any of the three is fine. Knockoffs are the actual problem to avoid.
- Body protocols favor Ultraformer III. If body HIFU is part of your plan, the deeper depth options give Ultraformer III a meaningful advantage.
- Real-time imaging favors Ulthera. If you want the visualization feature, Ulthera is the only platform that offers it.
- Ask the operator. The operator's experience matters more than the device. A senior operator on any genuine platform will produce better results than an inexperienced operator on the most expensive platform available.
Why some clinics use multiple platforms
Larger dermatology and aesthetic practices sometimes operate two HIFU platforms simultaneously — typically Ulthera for face protocols and Ultraformer III for body work. This is a reasonable clinical setup that lets the practice match the device to the indication. Smaller clinics typically operate a single platform; this is also reasonable provided the platform fits the practice's typical patient profile.
Bottom line
Ulthera, Ultraformer III, and Doublo are the three reputable HIFU platforms in current clinical use. All three produce comparable results when operated skillfully. The bigger question for any patient is not "which of the three" but "is the device real and is the clinical setup appropriate for full-energy protocols." The brand matters less than the operator and the infrastructure.
