HIFU (high-intensity focused ultrasound) is the leading non-surgical face-lifting technology — when done correctly. This guide helps you distinguish serious clinics from marketing and understand realistic outcomes from a well-performed HIFU treatment.
What makes HIFU work
HIFU is a technology, not a brand: several manufacturers make focused-ultrasound devices. What matters most for the result is energy reaching the SMAS layer (4.5 mm) and the dermis (1.5 and 3.0 mm) with a depth plan for each zone, and a physician with experience performing it. Low-energy or poorly planned HIFU gives poor or asymmetric results.
What to ask before paying
- Who performs the treatment? At Elyzea, Dra. Geldres, a plastic surgeon, performs it herself.
- Which depths are treated in each zone, and why?
- What pain management is offered so the full energy can be delivered?
- What result is realistic for your case, and when will you see it?
- If the answer is vague or defensive, you already have your answer.
Why anesthesia matters for HIFU
HIFU at SMAS depth (4.5 mm) can be painful. The easy way to "fix" that is lowering the energy — which also lowers the result. A clinic with an on-site MD anesthesiologist can run full energy comfortably with nerve block or light oral sedation.
If a clinic tells you "it doesn't hurt" or "only topical anesthesia," they're probably reducing the energy to make it tolerable — and that's why no result is visible three months later. Proper anesthesia isn't a luxury: it's what lets the treatment do what it promises.
Real results and timeline
HIFU stimulates new collagen production. That means: subtle changes at 2-4 weeks, full result at 3-6 months, 12-18 months duration with good maintenance.
Not instant like a filler. If you want next-day visible effect, HIFU isn't right alone — combine with hyaluronic acid or thread lift. A good clinic tells you before charging.
HIFU prices in Lima (2026)
Elyzea Miraflores publishes openly: HIFU full face S/1,000 (~US$286), face + neck S/1,500 (~US$429). Includes proper anesthesia to run full energy.
Serious Lima clinics range S/800-2,500 by zone. Below S/600 for full face, ask what energy and how many shots the session includes. The same session in the US runs $2,500-3,500 — the medical-tourism savings are real, but only if you verify who performs the treatment and how.
When HIFU isn't the right option
Severe sagging (marked jowls, clear skin excess) won't be solved by HIFU alone — it's a complement, not a surgical substitute. For moderate-severe sagging, combine with thread lift, Morpheus8, or evaluate surgery with a plastic surgeon.
Very thin skin or patients with minimal subcutaneous tissue may be poor HIFU candidates — the energy needs tissue to dissipate safely. Dra. Geldres identifies this for your case before billing.
Frequently asked questions
How many HIFU sessions do I need?
For most patients, one session per year maintains results. Moderate sagging may benefit from an initial session plus a booster at 6 months, then annual maintenance.
Is HIFU painful?
At full energy (the kind that gives results), yes it can be intense. That's why we recommend clinics with proper medical anesthesia — topical + nerve block or mild oral sedation. The difference between a 'painless' HIFU and an effective one is usually the anesthesia.
Is there downtime?
Minimal. Normal activities the same day. Some sensitivity or redness for 24-48 hours. No real restrictions beyond avoiding sauna and extreme exercise for 24 hours.
Does HIFU work for double chin?
Yes, particularly well. Moderate jowls/double chin respond well because the tissue is dense enough and the area accepts the 1.5/3.0/4.5 mm depths that HIFU treats.
How do I choose a HIFU clinic?
Ask who performs the treatment, which depths are treated in each zone, and what pain management is offered. A serious clinic answers without defensiveness and tells you honestly whether HIFU is right for you.
