The straight answer
Most people tolerate HIFU well and the procedure is designed to be relatively comfortable. Some people may describe the treatment as mildly uncomfortable and some may find it not bothersome at all. Many clients even fall asleep during HIFU treatments.
It’s a treatment people book again, which is the most useful signal there is on comfort.
What the sensation actually is
As the ultrasound energy is delivered, you’ll feel tiny amounts of energy being deposited to precise depths. People describe it variously as a warm prickle, a brief tingle, or a small deep pulse. Importantly, the sensation only lasts while the energy is being delivered. There’s no lingering ache between pulses.
What changes how it feels
- Your own pain threshold, which varies enormously between people
- The area being treated. Bonier areas such as the jawline and forehead tend to be more sensitive than fleshier ones
- The depth being worked at, since deeper passes feel different to superficial ones
- The energy settings, which the therapist controls and can adjust throughout
It’s adjustable, and you should say so
The HIFU device is able to be adjusted to ensure the client’s comfort. This is the part people don’t realise: the settings aren’t fixed for the session. Telling your therapist that a particular pass is uncomfortable is useful information, not a complaint, and it lets them adapt.
Maintaining open communication with your practitioner about your pain tolerance helps them adjust the intensity of the treatment.
Afterwards
The skin might appear flushed at first, sometimes lasting a little longer, but the redness should disappear within a few hours. Some clients experience slight swelling, tingling or tenderness to the touch. These are temporary. Less common effects may include temporary bruising or numbness on small areas of skin.
There’s no downtime. You can resume normal activities immediately and apply make-up as usual.
Making it easier
- Arrive without make-up on the treatment area, as cosmetics interfere with energy absorption
- Use sunscreen in the days beforehand. Sunburned or tanned skin is more sensitive during and after treatment
- Eat beforehand rather than arriving on an empty stomach
- Say something the moment a pass is uncomfortable
Common questions
Does HIFU hurt?
Most people tolerate HIFU well. Some describe it as mildly uncomfortable and some find it not bothersome at all. The sensation only lasts while the ultrasound energy is being delivered, and the device can be adjusted for your comfort.
Which areas are the most sensitive?
Bonier areas such as the jawline and forehead tend to be more sensitive than fleshier areas.
What should I do before my appointment?
Refrain from wearing make-up on the treated area, as cosmetics can interfere with the procedure and compromise ultrasound energy absorption. Use sunscreen in the days leading up, since sunburned or tanned skin may be more sensitive.
