In short. One long session or a series, the review point afterwards, and a realist's account of what has to be spent before a result appears.

Key points

  • A session takes about an hour out of a day, but the review sits two to three months later and nothing is knowable before it.
  • A course that repeats without a review point spends months rather than hours, and those months are the part no refund returns.

The cost of this treatment is usually discussed as a number, and the number is the least useful part of it. What a person actually spends is visits, hours in a treatment room, and months of waiting before the result is knowable.

One session or a series

Some plans are a single long session covering the face and neck; others spread the same work over a series of shorter ones across several weeks. The difference is a judgement about the area to cover, how much discomfort is reasonable in one sitting, and how the skin responded. A series is not a larger treatment than a single session; it is the same work divided so that each sitting is tolerable.

The visits that are not sessions

A plan includes an assessment before anything is booked and a review at two to three months, and neither is a session. The assessment is where the diagnosis is made and where the ceiling is stated. The review is where a standardised photograph is compared and the course is judged. Counting these as overhead is the commonest way to end up with a plan that has no judgement point in it.

What you cannot get back

A session takes about an hour out of a day, but the review sits two to three months later and nothing is knowable before it. A course that repeats without a review point spends months rather than hours, and those months are the part no refund returns.

The interval, and what sets it

Where more than one session is planned, the interval is set by how the skin responds rather than by a fixed schedule. That means the plan cannot honestly say in advance exactly when the next visit falls. What it can say is what the review is looking for and what would make the course stop.

What makes the total larger than it looks

A course that continues past its review point without a measurable change is the largest avoidable cost in this treatment, and it is also the commonest, because continuing is the default and stopping requires somebody to make a judgement.

What is not included

Time off work is usually not needed, because there is no wound and no anaesthetic, and most people return the same day. What no plan includes is a second opinion, and where an operation is the honest answer, that opinion is worth arranging before further sessions rather than after them.

Be careful with a plan that

  • Names a number of sessions with no review point and no stopping condition.
  • Offers a discount for committing to a course before the assessment has been done.
  • Describes the result as certain, or the number of sessions as fixed for everyone.

How the result is judged, and when a course should end, is described in Results Over Months, Not Days. Where the honest answer is a different treatment, the options are set out in Alternatives to Ultrasound Tightening, Surgical and Otherwise.

Frequently asked questions

Why can the clinic not tell me the number of sessions in advance?

Because the interval and the number depend on how your skin responds, which is not knowable before the first treatment is judged. What can be stated in advance is what the review is looking for, when it happens, and what would make the course stop. A fixed number quoted before an assessment is a guess presented as a plan.

Is there any way to reduce what a course costs?

The honest way is to have a review point and to stop when the photograph shows nothing measurable. A course that ends at its review costs less and produces the same information as one that continues. Discounts offered for committing to more sessions before an assessment do the opposite.

How much time off work does this treatment need?

Usually none. There is no wound and no anaesthetic, so most people return to work the same day or the next, and the tenderness that follows does not prevent ordinary activity. What the treatment does require is patience, because the result is not knowable for two to three months.

Risks & Limitations

  • The result builds slowly and modestly, over roughly two to six months, and no outcome can be guaranteed. At the review point, more sessions of the same treatment are unlikely to be the answer if a standardised photograph shows nothing measurable.
  • Patches of numbness and tingling over the treated area are common after a session. They usually settle over days to weeks, and a patch that spreads rather than shrinks, or that is unchanged after several weeks, requires assessment.
  • Brow weakness and a change in contour are uncommon, and they follow treatment at the wrong depth. The layer being treated sits near a small sensory nerve in some places and near a nerve that moves muscle or a compartment of fat in others, so the depth is an anatomical decision rather than a technical setting.
  • The surface is left intact, so there is no wound and no resurfacing effect. Pores, scars, pigment and creases etched into the skin are not changed, and nothing here removes skin or repositions a face that has descended.

When to Seek Care

  • A numb or tingling patch that is spreading rather than shrinking, or that is unchanged after several weeks.
  • Any weakness in the brow, any difficulty closing an eye, or a change in the shape of the face.
  • A blister, a burn or spreading redness at the surface, or pain that is worsening rather than settling.
  • Fever with warmth or discharge in the treated area — infection is uncommon because there is no wound, but it requires prompt assessment.
