What it's for

Lift or tighten skin using RF or ultrasound energy without surgery

Before you book

What to ask, what to verify, and what may change the decision — before you commit to an appointment.

Checklist

Which device, and what is it FDA-cleared for
How much treatment (lines or pulses) does this price include
Who operates it, and what is the plan for burns or nerve irritation

These are the items most likely to change what you pay, what you get, or what happens if something goes wrong. Take them with you — or and bring it.

From Vanity or Vice

Read the long version when this is the appointment you’re actually considering.

Spa Intelligence keeps the working checklist short. These publication pieces carry the fuller argument, source file and maintenance context.

The ongoing commitment

The first appointment is one number. The useful number is the commitment you can reconstruct from the written plan: what it takes to start, what lands inside the first 12 months, and what an ordinary maintenance year looks like after that.

To start

Everything required before the first meaningful result: the initial session or series, mandatory add-ons, deposits and planned review.

First 12 months

The starting course plus repeats, maintenance visits and known follow-up costs that fall inside the first year.

A normal maintenance year

What the plan costs after the initial course is over. Keep this separate from the first-year number so a package does not make upkeep disappear.

What the treatment guide says to clarify

Results develop over months and may last a year or more. Ask how often repeat treatments are recommended and what they cost.

What belongs on the receipt

How many sessions or units the starting plan actually includes.
Which follow-up, touch-up or review is included and which is separately priced.
When credits, packages or banked units expire and what happens if the plan changes.
What the practice expects maintenance to look like after the initial course.

Results reported to last: 24–36 months

Repeated as it wears off, that is no repeat inside twelve months.

Do not make the benchmark do the quote’s job.

Published averages have a source year. Reader ranges have a quote month and a rolling inclusion window. Neither is a current local quote, and a per-unit number is not interchangeable with a per-session number. Keep the dates and units attached when you compare.

How it’s priced

Per treatment, sometimes priced by area or by the number of lines or pulses.

What a complete quote says

A written quote that answers the questions has:

Device name
Areas and pulses or lines included
Total price

Who performs it

Energy device operator rules vary by state. See your state page.

Ask these three first

Which device, and what is it FDA-cleared for?
How much treatment (lines or pulses) does this price include?
Who operates it, and what is the plan for burns or nerve irritation?

Phrases worth a second look

“Non-surgical facelift”
An outcome claim. Ask for realistic expectations in writing.

Read an ad in the claims library

The 2 a.m. plan

If something is wrong tonight, the plan should cover:

A contact for burns, welts or numbness after treatment

If you think it’s an emergency, call 911 or go to an emergency department.

The days after

Worth asking before the appointment, not after:

When would any change be visible, and is a review visit included?

10 Facts about What FDA Does and Does Not Approve #FDAFacts (1-10) (opens YouTube in a new tab)
The regulator itself, stating the boundaries of its own authority. Every downstream claim is measured against this.
What it answers
Which categories the agency actually approves, and which it never does.
What it doesn’t
Whether any treatment suits you, or what it would do.
Why it’s here: Short, blunt, and from the agency whose name is being borrowed. If a room says a facial or a protocol is FDA approved, the category may not be approvable at all.

A regulatory consultancy walking through five distinct statuses and the evidence burden attached to each.
What it answers
What registered, cleared, granted, authorized and approved each legally mean.
What it doesn’t
Whether a specific device is right for you, or what result to expect.
Why it’s here: Registration is a listing. Clearance is a similarity argument. Approval is a review of evidence. Ask which of the five the machine holds, and for what indication.

What it answers
What a manufacturer or clinic may and may not claim about a machine.
What it doesn’t
Any judgement on a particular device, clinic or outcome.
Why it’s here: A device is cleared for a stated indication, not for everything in the brochure. Ask which indication the clearance covers, and whether the treatment on the menu sits inside it.
