They created a concept, a new treatment niche, and the name stuck: Ulthera or Ultherapy. The principle is based on focused ultrasound. A high-intensity ultrasound focused on a specific trigger point (HIFU – High-Intensity Focused Ultrasound). The shot provides tissue contraction in a non-surgical and non-invasive way.

During the procedure with micro-focused ultrasound devices (Ulthera, Doblo, Accutyte), the microfocused ultrasound delivers thermal clotting points (PCT) in a series of lines at 2 depths: deep dermis, at 3mm depth, and in the muscular layer. – SMAS (superficial muscular aponeurotic system) at a depth of 4.5 millimeters.

Ultrasound energy is focused at a point below the skin’s surface, focusing on  ​​about 1 cubic mm per point, causing immediate collagen contraction and initiating the synthesis of new collagen as the tissue retracts and becomes thinner. Firmer.

Interesting: after treatment, the epidermis (skin surface) is not marked, so there are no restrictions on sun exposure and work routine. Recent work suggests that microfocused ultrasound devices (Ulthera, Doblo, Accutyte) are safe for dark and dark skin, unlike most lasers that are safer on fair skin.

Treatment can be carried out in summer and winter.

Benefits:

  • Ulthera combines optimal depth, temperature, and accuracy without affecting the epidermis;
  • Can be used in I-VI phototypes throughout the year;
  • Complete treatment in a single session of 45-60 minutes;
  • Excellent alternative for mild to moderate sagging patients who are not ready for a facelift or surgery.

The System

The interaction with the system takes place through a 27″ touchscreen display where we can visualize the image provided by the ultrasound technology, focusing on the treatment with 1.5mm, 3mm, 4.5mm, up to 8mm tips.

In A Category Of Its Own

Other micro-focused ultrasound devices followed later, with more affordable prices, less pain, and comparable, if not better, results.

It is the first and only non-invasive technology that has received an FDA indication for sagging. Unlike traditional laser and radiofrequency equipment, which generate tissue heat through the skin’s surface, Ulthera® delivers micro-focused ultrasonic energy for tissue heating at an optimal temperature for neocollagenesis (> 60°C) without affecting the epidermis, like lasers. Significant skin support and sagging results can be achieved from just a 60-minute session with no downtime. Learn about hifu side effects (hifu ผล ข้าง เคียง which is the term in Thai) here.
