Does HIFU hurt? What treatment actually feels like

HIFU is uncomfortable rather than painful for most people, and the feeling stops the moment the energy stops. The honest answer is that it depends on where on your face we are working, the energy level, and you.

What you feel while it is happening

HIFU stands for high intensity focused ultrasound. The handpiece sits on a layer of gel and sends tiny points of heat to a set depth under the skin, in lines about three centimetres long. Each line takes a second or two. The device makers describe the sensation as momentary discomfort while the energy is deposited. A 2025 review of HIFU complications describes it as a deep warmth or tingling, mild to moderate, that varies with the energy level, the area being treated and the person's own threshold.

In the room it feels like this. A line of quick, hot pinpricks, or a deep ache that comes and goes with each line. It is sharpest where bone is close under the skin, so the jawline and the cheekbone are the moments most people notice. The fleshier parts of the cheeks and under the chin are usually easier. The forehead is treated at a shallower depth.

Nothing lingers between lines. You are not sore while we reposition the handpiece, and most people describe it afterwards as something they got through rather than something they enjoyed.

How we keep it manageable

We do not routinely numb the skin for HIFU. That is a choice, and we want you to know why. The device has no imaging, so how the energy feels to you is one of the ways we know it is landing where it should. A sharp electric pain, a shooting pain along the jaw or any sudden change in facial movement means we lift the handpiece off at once. Numbing cream can hide those signals.

What we do instead: we start at the lower end of the energy range and raise it only if you are comfortable, we talk you through each zone before we start it, and we take breaks when you want them. A simple painkiller an hour before is your choice; avoid aspirin and ibuprofen that day because they can add to bruising. If you know your pain threshold is low, say so at the consultation and we will plan around it.

What you feel afterwards

The published device data give a clear picture of what is normal and for how long. Redness settles within a few hours. Swelling lasts from 3 hours to 3 days. Some people get raised lines where the energy went in; these fade within a week. Soreness, like the ache after a hard workout, lasts from 2 hours to 2 days. Tenderness when you press on the jaw or cheekbone can last 2 days to 2 weeks. Bruising, if it happens, fades over 2 days to 2 weeks.

In a 2015 study of 20 people treated across seven areas of the face, 6 had redness and swelling and 2 had bruising, all settled within 2 weeks, and no one had nerve palsy, blistering or fat loss at 6 months.

Less common: tingling, pins and needles, a numb patch or a temporary weak patch of muscle from an irritated nerve. These settle in 2 to 6 weeks in the device studies. The 2025 review reports temporary numbness along the jaw in 4 of 22 people in one study. Rarer still are burns, hyperpigmentation appearing at around three months, and loss of fat under the skin leaving a hollow. Fat loss is linked in the review to overheating, repeat passes over the same spot and too short a gap between sessions, which is why we do not repeat the deepest setting within six months.

When the result shows, and what it is not

The lift builds slowly as new collagen forms. In the 2015 study improvement was significant at 3 months and held at 6 months; at 12 months, 4 of 15 people reached still reported a partial effect. Most people need one session. Where there is more loose skin we offer up to three, and we decide at your 12-week review whether another will help.

HIFU is a lift and firming, not a surgical facelift. Thin skin with little fat and heavy laxity respond less. If what bothers you is crepey, dull skin rather than sagging, a skin booster may be the right choice instead of HIFU, and we will say so. Results vary and cannot be guaranteed.

Who it suits, and who it does not

It suits mild to moderate laxity of the brow, cheeks, jawline, under the chin and neck, most often in people in their thirties and forties, who want a gradual change without needles.

We do not treat anyone under 18, anyone pregnant or breastfeeding, anyone with a pacemaker or other electronic implant, or metal in the area. A clotting disorder, blood thinners, liver, kidney, heart or lung conditions and recent surgery in the area mean we cannot treat. We never treat the eyelids or under the eyes, because eye injury has been reported after eyelid HIFU, and we never treat the front of the neck or the chest over the heart. We do not treat over filler until it has gone, and we wait four weeks after any prescription treatment for expression lines in the same area. If your face is slim with little fat in the cheeks, we do not use the deepest cartridge there.

Risks and recovery

Common and short-lived: redness, swelling, soreness, tenderness, raised lines and bruising, in the timeframes above. Less common: tingling, numbness or a weak patch of muscle for 2 to 6 weeks. Rare: burns, scarring, pigment change, fat loss leaving a hollow, lumps, and nerve effects that take months to settle. You can go back to your day. For the first few days avoid heat, sun and hard exercise, and for two weeks avoid scrubs, peels and other treatments to the area.

FAQ

Does HIFU hurt more than microneedling or filler?

It is a different feeling. Filler and skin boosters are a few sharp moments with a needle; HIFU is heat and ache that comes and goes with each line and stops when the line ends. Most people find HIFU the more intense of the three during treatment and the quickest to forget afterwards.

Can I have numbing cream?

We do not use it as routine, because your feedback helps us keep the energy where it belongs. Tell us at the consultation if you are worried and we will talk through the options. A simple painkiller beforehand is your choice.

How long am I sore for?

Aching for up to 2 days, tenderness to touch for up to 2 weeks. Most people are back at work the same or next day.

Is the pain a sign it is working?

No. Discomfort tells us the energy is being delivered, not how much collagen you will make. A sharp or shooting pain is a reason to stop, not a good sign.

How much does it cost?

Full Face £250, Face and Neck £350, Brow Lift £200, Double Chin and Jawline £250, Neck and Decolletage £250, Body single area £250 per session.

What happens at the consultation?

We look at your skin and how much lift is realistic, go through your health and medicines, take photographs for your record and explain the risks and the alternatives, including doing nothing. If it is your first time we suggest a few days to think before treatment.
