Body and facial ultrasound: how many sessions you need, what it feels like, and real results
Body and facial aesthetic ultrasound reduces localized fat, tightens the skin, and rejuvenates without surgery — but results depend on the type of technology, the number of sessions, and the right candidate. An honest guide for patients in Colombia 2026

GSMED Imaging technical team — aesthetic ultrasound technology in Colombia
Based on: ASLMS (American Society for Laser Medicine and Surgery) 2023, Ultherapy Clinical Data 2024, ISAPS (International Society of Aesthetic Plastic Surgery) Statistics 2024, and aesthetic ultrasound practice in Colombia 2025–2026.
Before paying for an aesthetic ultrasound treatment, it is worth understanding exactly what the technology can and cannot do. Aesthetic ultrasound is not magic — it has precise indications, ideal candidates, and documented results. It also has contraindications that many aesthetic clinics do not mention. This guide provides the information you need to make an informed decision.
1. The two completely different uses of ultrasound in aesthetics
🔥
Facial ultrasound — tightening and lifting (HIFU)
HIFU (High Intensity Focused Ultrasound) concentrates energy in the facial SMAS (the deep muscle layer) at a depth of 1.5–4.5 mm, generating localized heat of 65–70°C that produces immediate collagen tightening and stimulates new collagen formation over the next 8–12 weeks. Visible result: non-surgical brow, cheek, neck, and chin lift. A single annual treatment in most cases. Brands: Ultherapy, Ultraformer III, HIFU 3D.

Body ultrasound — fat reduction (cavitation)
Ultrasound cavitation uses low-frequency waves (20–40 kHz) that generate microbubbles in adipocytes — upon implosion, they destroy the adipocyte membrane and release its contents into the interstitial space, where they are eliminated by the lymphatic system. It reduces volume in localized areas (abdomen, thighs, arms, flanks). It requires multiple sessions and combination with lymphatic drainage. It is not weight loss — it is localized volume reduction.
→ Adipocytes · 20–40 kHz · 6–12 sessions · Localized volume · Not weight
2. How many sessions you need — by technology and area
| Technology | Area | Recommended sessions | Interval between sessions | Visible result from |
|---|---|---|---|---|
| Facial HIFU (Ultherapy / Ultraformer) | Face, neck, décolletage, brows | 1 full session · Touch-up at 12 months | 12 months between full treatments | 4–8 weeks (progressive collagen neogenesis) |
| Body HIFU | Abdomen, thighs, arms | 1–2 sessions per area | 4–6 weeks between sessions | 8–12 weeks |
| Face (gentle rejuvenation) | 8–12 sessions in a protocol | 2–3 sessions per week | 4–6 weeks (cumulative effect) |
The correct expectation — what ultrasound DOES NOT do Aesthetic ultrasound DOES NOT eliminate obesity, DOES NOT replace a healthy diet or exercise, DOES NOT produce the same results as an abdominoplasty or surgical liposuction, DOES NOT tighten very loose skin (such as after massive weight loss), and DOES NOT work the same way in everyone. The best candidates for cavitation are people with a weight close to their ideal and localized fat resistant to exercise — not people with significant overweight.
3. Differences between facial and body ultrasound — they are not the same
😊
Facial HIFU — what it feels like
Sensation of intense localized heat during the shots — especially in the bony areas (cheekbones, jawline, forehead). Some patients describe it as deep "electric pricks." The discomfort lasts for the duration of each shot (fractions of a second). Post-treatment pain is minimal — mild facial erythema that disappears within hours. No recovery period — the patient can apply makeup the next day.

Body cavitation — what it feels like
Mild heat and vibration in the treated area — very well tolerated, without pain in most cases. Some patients perceive an internal hum (ultrasound at 20–40 kHz is just above the human hearing threshold — some hear it slightly). Possible temporary redness of the area for 1–2 hours. No recovery required — the patient can continue their day normally.
→ Painless · Mild heat · Internal hum · No recovery
⚠️
Common contraindications for both
Pregnancy and breastfeeding · Metal or electronic implants in the area to be treated (pacemakers, neurostimulators) · Facial metal implants in the facial HIFU area · Active infection, wound, or inflammation in the area · Active anticoagulation (higher risk of hematoma) · Active autoimmune diseases · Cancer in the area to be treated or recently in remission. A prior medical evaluation is mandatory.

4. Real results — what the evidence says
2.5 mm
Average brow lift with Ultherapy (Solta Medical Clinical Data 2024)
73%
Of patients with HIFU report subjective improvement in lifting at 6 months (Ultherapy 2024)
2–5 cm
Abdominal contour reduction with cavitation in 8–10 sessions (meta-analysis 2023)
12–18m
Duration of facial HIFU results before a touch-up
Is facial ultrasound permanent, or does it need to be repeated?
Facial HIFU produces results that last 12–18 months in most patients — after that, the natural aging process continues, and a touch-up may be required. It is not a permanent treatment because it does not stop aging — it stimulates the production of new collagen that temporarily compensates for natural loss. Patients who maintain good skincare (daily sunscreen, hydration, topical antioxidants) tend to prolong the results. The correct comparison is with Botox: HIFU works deeper, lasts longer, and has a progressive (not immediate) effect, but neither is permanent.
How much does facial HIFU ultrasound cost in Colombia?
In Colombia 2026, the price of a full facial HIFU session varies depending on the area and the equipment used: Full face + neck: COP 1,200,000–3,500,000 depending on the equipment brand (Ultherapy is the most expensive, generic Chinese equipment the most economical — with significant differences in efficacy). Specific area (only brows or only neck): COP 400,000–900,000. For body cavitation, the price per session varies between COP 80,000–250,000. A package of 10 abdominal cavitation sessions: COP 600,000–1,800,000 depending on the clinic.
