FAQ HIFU

Here are the questions most commonly asked by our patients regarding the medical facelift by Focused Ultrasound ( HIFU ).

- Are "HIFU" Focused Ultrasound akin to a surgical procedure?
No, in the cosmetic field ultrasound is not a surgical procedure! If certain classes of Ultrasound are used in surgical procedures, HIFU (High Intensity Focused Ultrasound) for cosmetic and anti-aging purposes are an absolutely non-invasive procedure, which allows to treat the deep dermis and SMAS (Superficial Musculo-Aponeurotic System), without any lesion or break in the skin.
- What is the difference between HIFU Focused Ultrasound and anti-aging lasers?
While lasers and radiofrequency will act on the more superficial parts of the skin (wrinkles and pigment spots, for example). HIFU acts on the deep layers that underlie the skin. These technologies are therefore complementary!
- Is HIFU technology safe?
Several hundred thousand treatments using focused ultrasound for cosmetic purposes have been carried out without problem around the world. In addition, focused ultrasound has proven its effectiveness and has been used for more than 50 years in other fields of medicine.
- For which type of patient is the HIFU "medical facelift" intended?
The right candidate for a medical facelift by HIFU has skin that sags visibly, but also to the touch. Sagging facial, neck or chest skin are often the first signs of aging. Patients in their thirties who have moderate hypermobility are also good candidates. Even if the medical facelift with HIFU cannot replace a complete surgical facelift, many patients now prefer a moderate medical facelift without any surgery rather than the scalpel. HIFUs are also a good solution for patients who wish to extend the effects of a previous surgical facelift.
- What areas can HIFUs treat? What results do we get?
HIFUs like the Ultraformer III treat sagging skin or a sagging of the face and neck by creating thousands of coagulation microdots at different depths to "tighten the skin from the inside". HIFU (Focused Ultrasound) is also used to correct the oval of the face under the chin, in particular the "double chin".
- Is it painful?
Patients notice temporary discomfort when energy is delivered to areas close to the bones. This can be reduced by taking an analgesic before the session.
- What will I feel during the session?
You will perceive the small amount of energy delivered by the focused ultrasound under the surface of the skin, which will create these thousands of invisible microdots. They stimulate collagen and re-anchor the skin.
- How long does a HIFU medical facelift session last?
Depending on the size of the area to be treated, a session will last from 20 to 60 minutes.
- How long do the obtained results last?
The real results take about 2 to 3 months to appear, the time necessary for the renewal of collagen to take place. Additional improvements might even appear up to 6 months after treatment. These results will last more than a year after the session. However, touch-ups will certainly be necessary in order to fight the ongoing aging process depending on the patient.
- How many sessions will I need?
The majority of patients perform only one or two sessions, depending on the laxity of the skin and the biological response to focused ultrasound on the reconstruction of collagen. Your doctor will be able to give you information about your personalized protocol.
- Does treatment require social eviction?
HIFU is a non-invasive procedure and there is no social exclusion. You can resume normal activity immediately after the session. Some patients describe a feeling of "bruises under the skin" on certain areas treated for a few days.
