Relatively little facial fat, with fine lines from reduced elasticity

What this treatment is

Thermage FLX delivers radiofrequency (RF) energy into the dermis to stimulate collagen production, helping to improve the fine lines and sagging caused by reduced elasticity. It's a lifting treatment with no downtime, suited to people who want to keep their normal routine.

What you can expect

Changes you'll notice afterward

Collagen continues building over the next 2 to 6 months, gradually improving elasticity and fine lines
Almost no downtime, with any mild redness typically fading the same day
You can wear makeup and go out right after treatment, without disrupting your routine
Can be combined with another lifting treatment for more fat or more significant sagging

Actual results and sensation vary by person. Your doctor will explain what to expect for your skin at your consultation.

How your doctor decides

Your doctor first checks your skin thickness and degree of elasticity loss to decide the right shot count and energy settings. If you have more facial fat or more significant sagging, your doctor may recommend combining this with another lifting treatment.

What you might want to know first

Process

After cleansing and applying numbing cream, your doctor personally operates the handpiece, adjusting energy and shot count by area. The full session takes about an hour, depending on the area treated.

Pain

Pain tolerance varies. You'll feel warmth and some stinging as the RF energy is delivered. Numbing cream is applied generously to reduce discomfort, and nitrous sedation or local injectable anesthesia can be added if needed.

Downtime

There's almost no downtime. You may see mild, temporary redness that typically fades the same day, and you can wear makeup and go about your day as usual.

How long it lasts

Results gradually improve as collagen continues to build over roughly 2 to 6 months, and how long they last depends on your skin and skincare habits.

Actual results and sensation vary by person. Your doctor will explain what to expect for your skin at your consultation.

Frequently Asked Questions

Which is better for me, Thermage FLX or Ulthera Prime?

They work at different depths. Thermage FLX focuses on dermal elasticity and fine lines, while Ulthera Prime focuses on deeper lifting. Your doctor will confirm which fits your skin at your consultation, and the two can also be combined.

Can I wear makeup and go out the same day?

Yes. Thermage FLX has almost no downtime, so normal cleansing and skincare right after your session is fine.

How often should I get it done?

That depends on your skin and how long your results last. Your doctor will suggest a frequency at your consultation, with no pressure to commit to a multi-session package upfront.

I have more facial fat. Will Thermage FLX still work for me?

If you have more facial fat or more significant sagging, your doctor will likely recommend combining Thermage FLX with another lifting treatment, since Thermage FLX alone may have limited effect in that case.
