The non-surgical facelift lifts and firms sagging skin using focused ultrasound to stimulate your own collagen — no cuts, no needles, and no recovery time. The best-known versions are Ultherapy and HIFU. Liftera 2 belongs to the same family of micro-focused ultrasound treatments, but it is a newer generation device, with Korean technology, developed to offer more comfort, faster sessions, and precise and customizable energy delivery. This guide explains how each one works, how they compare, and what to expect from a treatment with Dr. Renata Ralha in Rio de Janeiro.

What is a non-surgical facelift?
A non-surgical facelift is a treatment that firms and lifts the skin of the face, neck, and décolleté. No surgery, no incisions, and no general anesthesia. Instead of cutting and repositioning tissues as in surgical facelifts, it uses focused ultrasound energy to heat the deep supporting layers of the skin. This controlled heat activates the body's natural repair response, which then produces new collagen and elastin over the following weeks and months.
The result is a gradual and natural lifting effect — firmer skin, a more defined facial contour, and a renewed appearance — built up progressively and with no recovery time.
How do Ultherapy and HIFU work?
Ultherapy and HIFU work by delivering energy from microfocused ultrasound At precise depths below the skin—typically 1,5 mm, 3,0 mm, and 4,5 mm—reaching the SMAS, the same deep muscle layer that plastic surgeons pull on during surgical facelifts. At these depths, ultrasound generates tiny, controlled points of heat without damaging the skin's surface. The body responds by remodeling collagen and elastin, which firms and lifts the treated area over time.
Since the energy does not affect the skin's surface, there is no wound to heal. Most patients return to normal activities immediately.
Ultherapy vs. HIFU: What's the Difference?
The main difference is the real-time image. Ultherapy (technically called MFU-V, microfocused ultrasound) with visualizationThis device is the only one that shows the doctor an ultrasound image of the skin layers during the procedure, allowing them to position the energy exactly where it will have the most effect. In the United States, it is FDA-approved for lifting the brow, neck, and jowls, and for improving décolleté lines, and it is the non-invasive lifting device with the largest body of clinical evidence.
Conventional HIFU is the broadest category of high-intensity focused ultrasound. Most HIFU devices not It relies on real-time imaging, which is why they are sometimes called "blind"—the practitioner cannot visualize the exact layer being treated. HIFU still produces a good firming effect, but offers less visual control than Ultherapy.
In short: All Ultherapy is a form of ultrasound lifting, but not all HIFU is Ultherapy. Technology, precision, and level of evidence vary between devices—which is precisely why the doctor performing the procedure is just as important as the equipment.
What is Liftera 2, and why is it different?
Liftera 2 is a Next-generation microfocused ultrasound platform, based on Korean technology.Developed within the modern philosophy of facial rejuvenation associated with K-beauty — firm, defined, and natural-looking skin, without exaggerated changes and with a focus on comfort.
Like Ultherapy and HIFU, Liftera 2 stimulates deep collagen production to firm and lift the skin. What sets it apart is... , the He delivers this energy:
- Digital and fractional energy delivery. The Liftera 2 delivers ultrasound energy via digitally controlled actuation, distributing it across multiple focal points and depths. Many patients describe the sensation as quick, “warm tingles,” rather than the more intense discomfort reported with some previous generation devices.
- Designed for comfort. Its multipoint delivery with thermal control was designed to reduce pain and, in many cases, the need for anesthesia compared to older platforms.
- Quick and versatile sessions. A facial session lasts an average of 40 minutes, and the same technology can treat both the face (double chin, contour, eyebrows, eye area, neck) and the body (arms, abdomen, thighs).
- For medical use. Liftera is a platform designed to be operated by physicians — an important safety point, because microfocused ultrasound should always be performed under proper medical evaluation.
The Liftera 2 is a newer, more comfortable, and highly customizable platform that an experienced dermatologist can precisely adjust to your anatomy. The best choice depends on your degree of sagging and your goals—which is why Dr. Renata evaluates each patient individually, instead of applying the same device to everyone.
