Thermage tightens with radio waves and no needles — and yes, you can have it without leaving the island.

Is Thermage available on Koh Samui? Yes — Thermage, a monopolar radiofrequency skin-tightening treatment, is available on Koh Samui at doctor-led clinics such as LIV Clinic; it heats deep skin layers to tighten existing collagen and build new collagen, firming mild to moderate laxity without surgery or needles.

What Thermage is

Monopolar radiofrequency

The Cleveland Clinic describes radiofrequency skin tightening as using safe electromagnetic waves to heat the deeper skin and firm laxity. Thermage is a well-known monopolar RF device.

No needles, from the surface

Thermage heats a broad area of the dermis from the skin surface, so it needs no needles and has essentially no downtime.

How it works

Tighten now, build later

The heat immediately contracts existing collagen for a subtle firming, then triggers new collagen over the following months.

Best for laxity

Because it heats broadly, Thermage suits softening, crepey or mildly lax skin across an area, rather than deep structural lifting.

What it can treat

Thermage is commonly used for:

• Mild to moderate facial laxity
• Crepey skin around the eyes and cheeks
• Softening along the jawline
• Neck and under-chin firmness
• Some body areas

Thermage vs HIFU

They suit different concerns; see our guide to choosing.

What to expect

The session

A single session typically takes 30–90 minutes depending on the area, with brief pulses of heat; modern tips vibrate to improve comfort.

Results and longevity

Most people see the full effect over two to six months as new collagen matures, lasting around one to two years. Longevity varies.

Thermage, HIFU or both?

Different tools

Thermage (RF) suits surface laxity; HIFU suits deeper lifting. Some people benefit from one, some from a combination.

A consultation decides

An in-person assessment identifies whether your concern is surface laxity, deeper sagging or both.

Preparing for and recovering from Thermage

Preparation and aftercare are simple:

1. Have a consultation so Dr. Narathai can assess your laxity and suitability.
2. Arrive with clean, make-up-free skin.
3. Expect brief pulses of heat during treatment; tell your clinician if uncomfortable.
4. Resume normal activities the same day.
5. Use daily sun protection and keep skin hydrated.
6. Allow 2–6 months for the full result to build.
