Everything You Need to Know About Ultrasound For Cosmetic Procedures
Ultrasound, also known as sonography, has traditionally been used for medical imaging. Sonography involves sound frequencies higher than 20,000 Hz, or a higher sound frequency than what humans can pick up. These pulses of ultrasound are sent to the tissues using a probe, then the “sound” bounces back off the tissue.
Different types of tissues would reflect varying degrees of sound. These “sounds” are then recorded and displayed as an image on the screen, which the operator translates. There are different types of sonographic equipment for varying medical applications. Ultrasounds offer many advantages, from providing real-time imaging, portability, safety, and lower costs.
In dermatology, High Intensity Focused Ultrasound is applied for the treatment of solid benign tumors, like lipomas, and malignant tumors. In recent years, however, manufacturers began harnessing the power of ultrasound as a means to tighten skin, induce collagen synthesis, boost facial rejuvenation, reduce fat, reshape the body, and reduce the appearance of pigmentation.
Ultrasound waves are focused at precise points under the skin or fat, and produce micro thermal lesions
This is the basic principle of HIFU and it is known in the beauty and medical world by many names. You’ve probably heard about Ultraformer 3, Ulthera, Ulfit, ACTS, Liposonix, Ultrashape, or
One advantage of HIFU is the ability to treat at different layers, from superficial to deep. You can treat skin, muscle, and fat by carefully choosing your transducer and energy settings. It is also ideal to combine with other energy devices like lasers, threads, and fillers after a certain point. It also gives treatment options for patients that can’t tolerate light, metal implants, or needles, and for those who do not wish for surgery downtime.
Patients immediately feel tight after each session but results may vary depending on the machine and the doctor’s protocol. Because it relies on wound healing and not immediate suspension (like threads), it will take time to see the results. This is between two to three months, so the changes are subtle but cumulative.
The downside and risks
The treatment isn’t painless, especially in the bony areas. Topical anesthetic creams help only up to a certain extent. Due to the
It might sound too good to be true: an hour of treatment resulting in tighter, younger, and
Understand that knowledge of anatomy is very important when it comes to this procedure. Nerves and blood vessels change
HIFU for fat reduction and reshaping involves transmitting temperatures between 65 to 70 degrees Celsius. This instantly causes fat tissue death. Macrophages eventually clear out the destroyed fat tissues and the heat from the HIFU also stimulate collagen production, which improves the treated area. Results can be seen and measured a month after the procedure.
The ones used on the face would normally be at 4.5 mm with energies of about 3 joules. That is a huge difference in power, so post procedure, patients tend to look bruised. The bruising is similar to getting a liposuction without the surgery. Lately, a number of studies have come out, expounding on the use of HIFU for pigmentation or in combination with other materials like Radiesse for stretch marks.
Fat reduction is great for people who are not obese. One would need at least an inch of fat via body caliper to be considered a good candidate. The treatment aims to destroy fat, not muscle. If you are the type of person who will demand immediate changes, then this might not be for you. There are results, but they occur over time.
A doctor’s consultation is needed for the procedure. The treatment isn’t safe for pregnant women. Patients must also disclose any injections or implants prior to the treatment.
