HIFU (UTIMS A3): Where to have it done? Distinguish by degree of Sagging (skin laxity) and eye-area handling

HIFU (UTIMS A3) is suited for Sagging (skin laxity) that does not require surgery, so the basic approach is to choose a clinic that can determine whether your Sagging (skin laxity) can be adequately addressed by HIFU[1]. According to academic guidelines, while HIFU is effective for wrinkles and Sagging (skin laxity), it does not match the results of surgery or injection[2]. Safety considerations when treating around the eyes are also an important comparison point[3].

Is HIFU enough for your Sagging (skin laxity)?

First, you want to confirm whether HIFU suits your Sagging (skin laxity). HIFU is best suited for Sagging (skin laxity) that does not require surgical lifting[1].

According to the Japan Society of Aesthetic Plastic Surgery guidelines, HIFU's effects do not match those of surgery or injection, and the recommendation level is only "weakly recommended"[2]. Scarring is rare, and the risk of complications is rated as low[2]. If you have significant Sagging (skin laxity), see whether the clinic explains alternative methods including surgery.

How do they vary the depth of irradiation?

HIFU is a treatment that uses ultrasonic heat to create small heat points in deep skin layers or the underlying facial muscle layer (SMAS) to promote tightening[4]. The target depth is approximately 1.5–4.5 mm, and the layer affected varies with depth[4].

Since skin thickness varies by facial location, where and at what depth the treatment is applied affects both results and safety. Within the scope of research we gathered, no studies specifically examining the UTIMS A3 device itself were found. It is more practical to compare clinics based on whether they explain where on your face and at what depth they will apply treatment, rather than focusing on the device name.

What safety measures are taken when treating around the eyes?

Special caution is needed when treating the eye area. Cases have been reported of corneal (surface of the iris) burn-like injury from HIFU irradiation around the eyes[3].

This report indicates that it is necessary to set a clear upper limit on the intensity of treatment around the eyes and to apply it correctly[3]. The efficacy and safety of treatment on the eyelids have not yet been sufficiently established[5]. Ask whether treatment will be applied around the eyes, and if so, how the eyes will be protected.

What about pain, swelling, and number of sessions?

The biggest weakness of HIFU is that pain during treatment is noted to be significant[1]. In most cases, one or two sessions are sufficient[1].

Common side effects include facial swelling, redness, and temporary nerve discomfort, most of which resolve naturally over time[3]. Even minimally invasive treatments can result in complications[6]. It is reassuring to check in advance about pain management strategies and contact information in case of swelling.

Where to have it done? A guide when undecided

At your consultation, ask about the following points:

Assessment of Sagging (skin laxity): Will the clinic tell you whether HIFU is sufficient or whether an alternative method such as surgery would be appropriate?[2][1]

Depth of irradiation: Will they explain where on your face and at what depth they will apply treatment?[4]

Eye area: Whether treatment will be applied, and if so, how the eyes will be protected[3][5]

Pain and number of sessions: Pain management strategy and approximately how many sessions you will need[1]

How much your Sagging (skin laxity) will improve with HIFU, or whether it should be combined with other methods, cannot be determined from an article alone. At your appointment, have the degree of Sagging (skin laxity) and skin thickness examined, and decide together on the treatment location and depth.
