In short. What each treatment actually feels like, why numbing is used, what the face looks like afterwards, and why the phrase no downtime needs qualifying in both cases.

Key points

  • What it means is that nothing prevents you from working, driving or going about an ordinary day.
  • What it does not mean is that your face looks unchanged.
  • Redness, warmth and mild swelling for some hours, or tenderness and puffiness for several days, are the normal aftermath of heating tissue.

Both treatments are sold as lunchtime procedures with no downtime, and the phrase is doing more work than it can carry. Neither breaks the skin, neither requires time away from work, and both leave a face that looks as though something was done to it. Understanding what the hours and days actually feel like is part of deciding whether the modest change is worth the disruption.

What radiofrequency feels like

Warmth, building to a prickling or stinging sensation as the handpiece passes, and then fading. Most people tolerate it without difficulty, and many describe the discomfort as less than expected. A single session is short. Sessions are spaced weeks apart, and the area may be pink and warm for some hours afterwards, occasionally with mild swelling. Numbing is available and is sometimes used on sensitive areas or at higher settings.

What microfocused ultrasound feels like

Sharper and deeper. The focused points produce a brief, intense discomfort that patients consistently describe as more than they expected, and the honest comparison is that this is the less comfortable of the two. Numbing is used because of it, and it reduces rather than removes the sensation. The face can be swollen and tender for several days afterwards, and some patients find it uncomfortable to chew or to sleep on the treated side for a night or two.

Qualifying the phrase no downtime

What it means is that nothing prevents you from working, driving or going about an ordinary day. What it does not mean is that your face looks unchanged. Redness, warmth and mild swelling for some hours, or tenderness and puffiness for several days, are the normal aftermath of heating tissue. Both treatments are compatible with a desk and incompatible with an event at which you need to look untouched.

The advice that follows either treatment

Avoid intense heat for a short period — saunas, hot baths, strenuous exercise and direct sun. Keep the skin moisturised and protected, and do not scrub, exfoliate or use strong active ingredients on it while it is tender. Cold compresses help swelling and are safe. Sleep with the head slightly raised if the face is puffy. Report blistering, crusting, severe pain, numbness or weakness rather than waiting for a review, because those are not ordinary aftermath and are easier to manage early.

What to tell the clinic before you book

  • Any active skin disease, recent sun exposure, or a history of cold sores, poor scarring or slow healing, all of which change fitness for treatment.
  • Any medicine that affects healing or clotting, and any implant or filler in the area, which may change where energy can safely be delivered.
  • Any event at which you need to look untouched in the following week, because neither treatment is compatible with one.

The recovery from an energy treatment is short and it is real. It is also the smaller half of the decision. The larger half is whether a modest, temporary change in mild laxity is what you are looking for, and whether anything has descended. Recovery does not affect that answer.

Frequently asked questions

Is there really no downtime after these treatments?

There is no wound and no time away from work, and there is an aftermath. Redness, warmth and tenderness for some hours follow radiofrequency; swelling and tenderness for several days are common after microfocused ultrasound. The phrase is accurate about work and inaccurate about appearances, which is why neither treatment belongs immediately before an event.

Will I need numbing?

Microfocused ultrasound is usually given with numbing, because the focused points produce sharp, deep discomfort. Radiofrequency is often tolerated without it, felt as a warm or prickling build-up. If numbing is offered for radiofrequency it is because of the settings or the area, not because the treatment is expected to be unbearable.

What should I avoid after treatment?

Intense heat for a short period: saunas, hot baths, strenuous exercise and direct sun. Keep the skin moisturised and protected, do not scrub or exfoliate it while it is tender, and do not arrange another energy treatment on the same area before the first one has been assessed.

Risks & Limitations

  • Redness, warmth and tenderness for some hours after radiofrequency, and swelling or tenderness for several days after microfocused ultrasound, are expected rather than complications.
  • Both treatments can burn. Blistering, crusting and a burn that leaves a mark are recognised risks, and they rise with higher settings and with skin that heals poorly.
  • Microfocused ultrasound is genuinely uncomfortable during treatment; numbing reduces the sensation rather than removing it.
  • Contour irregularity — hollowing or an uneven surface from over-treatment — is a recognised risk of the deeper ultrasound planes.
  • Nerve-related problems, including numbness or weakness affecting part of the face, are recognised risks of microfocused ultrasound in inexperienced hands.
  • Neither treatment is reversible. There is no way to remove energy that has already been delivered, and a contour or nerve problem cannot simply be undone.
  • The change is modest and temporary: it develops over weeks to months, is judged fairly at 3–6 months, and fades as ageing continues. Maintenance is part of the plan.
  • Neither treatment repositions descended tissue, removes fat, restores volume or changes skin pigment, at any setting or over any number of sessions.
  • Active skin disease, recent sun exposure, a history of poor scarring and some medicines change fitness for treatment, and no outcome is guaranteed for either option.

When to Seek Care

  • Blistering, crusting, or skin that turns white, grey or dusky in the treated area — contact the treating team the same day.
  • Severe or worsening pain, or swelling that continues to increase after the first 48 hours.
  • Numbness, weakness or drooping affecting part of the face, or a change in your ability to close an eye or smile evenly — seek urgent assessment.
  • Fever, spreading redness, warmth or discharge from the treated area.
  • A burn or wound that is not healing, or any break in the skin that appears after treatment.
  • Difficulty breathing, chest pain or fainting — seek emergency care immediately.
