In short. It does not remove skin, remove fat, change pigment or stop ageing. The complaints people bring to a tightening consultation that this treatment cannot address.

Key points

  • Deep folds from the nose to the mouth; heaviness that has settled along the jaw; hollowing under the eyes; a neck that has begun to look like a curtain; dark circles; an asymmetry that was always there; and a general wish to look less tired.
  • None of these is a skin-tightness problem in the sense this treatment addresses, and each has its own answer elsewhere.

This subject is easier to understand as a list of things the treatment does not do. The list is longer than the list of things it does, and a consultation that does not work through it leaves the patient to find out afterwards.

It does not remove skin

Skin that hangs is skin that is in excess, and no energy delivered through the surface removes it. Firming changes how skin sits on the face; it does not reduce how much of it there is. Where the excess is the visible problem — folds at the jaw, crepey skin on the neck, an eyelid that rests on the lashes — an operation that removes the excess is the treatment that addresses it.

It does not remove fat, and does not replace it

Fat is not reduced deliberately here, though it can be reduced as a complication. Nor is it restored. Volume lost with age is not replaced by firming, and skin that firms over a hollow makes the hollow more visible rather than less. Where the complaint is a flattened cheek, a temple that has sunk, or a face that looks gaunt, the answer lies in volume rather than in tightening.

It does not change pigment, and does not stop ageing

Sun spots, melasma and uneven tone are pigment problems, and they are treated by targeting pigment. Heat delivered for tightening can make pigment worse rather than better, and skin that tans easily carries more of that risk. Nor does the treatment pause the process that caused the laxity: skin continues to lose elasticity, fat continues to change, and the bone beneath continues to change shape.

The list patients most often arrive with

Deep folds from the nose to the mouth; heaviness that has settled along the jaw; hollowing under the eyes; a neck that has begun to look like a curtain; dark circles; an asymmetry that was always there; and a general wish to look less tired. None of these is a skin-tightness problem in the sense this treatment addresses, and each has its own answer elsewhere.

And it does not answer a face that has moved

Where the problem is position rather than firmness, the honest answer is the operation that repositions tissue. That is not a failure of this treatment; it is a different problem. Where the change is small enough that neither is warranted, the honest answer is nothing, reviewed in a year, which a patient is entitled to hear rather than have to infer.

Do not expect this treatment to change

  • Hanging skin, or skin that needs to be removed.
  • Lost volume, hollowing, or a face that has descended.
  • Pigmentation, pores, scarring, or the colour and texture of the skin.

What the treatment does reach is set out in What RF Tightening Reaches, and What It Misses, and where each of these complaints is answered instead is described on the laser and energy-based treatment pages.

Frequently asked questions

Will it help the folds beside my nose and mouth?

Not in the way most people mean. Those folds are usually produced by the descent of the midface rather than by looseness in the skin over them, and firming the skin does not reposition what has moved. Where the fold is a shadow cast by lost support above it, tightness in the skin is not the answer either.

Will it help my jowls?

Where the jawline has blurred because the skin lost its grip and the tissue has not moved far, a modest improvement is possible. Where the heaviness along the jaw is tissue that has descended, firming does not lift it, and the operation that repositions it is the treatment that answers it.

Is it worth having for the texture of my skin?

That depends on what has changed. Thin, sun-exposed skin that has lost some quality can look a little smoother, because what is being treated is the skin itself. Pigmentation, pores and scarring are different problems, and heat delivered for tightening can make pigment worse rather than better.

Risks & Limitations

  • Heat injury is the characteristic risk: a burn or blister where the skin was heated past what it tolerates, usually where the handpiece paused too long in one place. Blistering is not a normal part of recovery and should be reviewed rather than dressed at home.
  • Fat beneath the skin can be reduced by heat, producing a hollow or contour dip rather than a tightening. It usually appears weeks to months later, it is the hardest of the risks to correct, and the fat that has gone does not return.
  • Pigment can darken or lighten after treatment, and lightening where pigment cells have been injured is not reliably correctable. Skin that tans easily carries the greater risk.
  • Tightening is not lifting. The support beneath the skin is not repositioned, nothing delivered through the surface removes skin, and the change is modest and not permanent.

When to Seek Care

  • Blistering, broken skin, or a burn that is not settling after a few days.
  • A hollow or contour dip that appears in the treated area weeks after a session.
  • Skin turning white, grey or dusky during a session, or pain that is sharp rather than hot.
  • Increasing pain, warmth, redness or swelling in the treated area, or fever after treatment.
