What is Thermage ?
Thermage is a non-surgical skin tightening treatment that uses radiofrequency (RF) energy to heat the deeper layers of the skin, stimulating collagen production and improving skin elasticity.
Unlike invasive procedures, Thermage works from within the skin to gradually lift, tighten and smooth areas affected by aging. It is especially popular with patients who want natural tightening without injections or surgery.
What can Thermage treat?
How your session goes.
Consult your doctor
A 1:1 consultation to check your skin and plan the areas and energy levels.
Cooling for comfort
A cooling gel or tip is applied so each pulse feels comfortable.
RF pulses
Controlled radiofrequency energy is delivered in pulses to the targeted areas — about 30–90 minutes.
Back to your day
No anesthesia is usually needed, and you can return to daily activities immediately.
Does it hurt? Any downtime?
How it feels
Most patients feel a brief heating sensation followed by cooling with each pulse. Discomfort is generally mild and well tolerated — the device is designed with comfort features to minimize pain.
Little to no downtime
You may notice, for a few hours to a couple of days:
- Mild redness
- Temporary swelling
- Slight sensitivity
When will I see it ?
An early lift
Some tightening can be felt shortly after treatment.
The real glow-up
The most noticeable results develop as new collagen builds.
Lasting firmness
Results typically last 6–12 months or longer, depending on your skin and aging process.
Most patients achieve results with a single session; a yearly maintenance session helps sustain collagen and firmness.
