Thermage FLX

Non-surgical tightening that reorganizes collagen beneath the skin with radiofrequency heat energy

ABOUT

What is Thermage FLX?

Thermage FLX delivers monopolar radiofrequency energy to the skin to encourage collagen contraction and remodeling.

It is often chosen to naturally refine overall skin laxity and fine lines across the face.

The key is to assess where and at what depth the face has loosened before selecting the energy needed, rather than focusing on the device name.

HOW IT WORKS

How does it work?

It heats a broad area evenly while cooling protects the surface in contact.

Thermage FLX uses radiofrequency energy to heat skin tissue evenly while a cooling system protects the surface. Heat-stimulated collagen contracts, then continues remodeling as skin firmness gradually improves.

WHERE IT WORKS

0–0.1 mm

Skin surface

Where texture and hydration show

0.1–3.0 mm

Within the skin

Where firmness and density are formed

3.0 mm or deeper

Deeper layer

Where the facial contour is supported

These are general depth ranges that vary by area and individual.

IDEAL FOR

Recommended for people who

Have overall skin laxity and reduced firmness

Want natural tightening without dramatically changing facial contours

Are concerned about fine lines around the eyes and face

Prefer gradual change after a single treatment

TREATMENT AREAS

Main treatment areas

Full face
Eye area
Cheeks
Jawline

03
A tightening change that makes facial contours look firmer
04
Collagen remodeling that continues naturally over time

KEY POINTS

Key treatment points

01
Broad, even heating of skin tissue with monopolar radiofrequency
02
Cooling before and after energy delivery protects the skin surface
03
Addresses full-face firmness, fine lines and texture in one treatment

RESULT JOURNEY

How it changes over time

Immediately after treatment, the skin may feel slightly firmer. Over the following weeks, collagen remodeling continues, naturally refining facial contours and firmness, with changes settling around two to three months.

INEE APPROACH

How INEE approaches this treatment

We assess skin firmness and facial structure together, then identify the areas that need treatment most.

We plan an individual treatment range based on the device characteristics and treatment depth.

We aim to naturally restore the face’s original balance rather than pursue dramatic change.

RECOVERY & CARE

What to check before and after treatment

Before treatment

During consultation, tell us about recent fillers, thread lifts or energy-based treatments and the facial areas that concern you most. Shot count and focus areas are determined according to face size and skin firmness.

Immediately after & recovery

Most people can return to daily activities immediately after treatment. Temporary redness, warmth or mild swelling may occur but usually settles quickly.

Aftercare

On the day of treatment, avoid excessive rubbing and hot saunas, and moisturize well. Continue sun protection and discuss the next maintenance timing according to your skin condition.

NEXT STEP

Confirm a treatment plan that fits you through consultation

The right treatment direction may vary with your current skin condition and desired change. Start with a comfortable consultation.

FAQ

Questions before booking

What are the differences between Thermage FLX and Ultherapy Prime?

Both treatments use non-surgical skin tightening, but they have different energy methods. Thermage FLX uses monopolar radiofrequency (RF) to heat the skin tissue uniformly and induce collagen remodeling, while Ultherapy Prime delivers focused ultrasound at a chosen depth. The choice between these devices depends on the location of skin laxity and facial structure.

How are 600 and 900 shots chosen for Thermage FLX?

Shot count depends on facial size, treatment coverage, whether the eye area, jawline, or neck is included, and skin firmness. More is not automatically better: placement matters, so the treatment area and priority zones should be planned first during consultation.

When can I expect to see the effects of Thermage FLX, and how long do they last?

Some patients may feel tightening immediately after treatment, but most changes occur gradually over 2–6 months as collagen remodeling progresses. According to official data, measurable results can last for 1–2 years after a single treatment, depending on skin condition and aging process. Regular skin evaluations are necessary to determine the optimal maintenance time.

Does Thermage FLX require anesthesia, and can I resume my daily activities immediately after treatment?

Thermage FLX may cause a sensation of energy delivery at the moment of transmission, but the system's cooling and vibration functions help to alleviate discomfort. Most patients can return to their normal activities right away, although some minor redness or swelling may occur. If you are sensitive to pain, it is recommended that you discuss comfort measures with your medical team before treatment.

Can I get Thermage FLX just once?

Thermage FLX is not a treatment that requires multiple sessions, and official data suggests that changes can occur over several months after a single treatment. However, since aging continues, the timing of maintenance treatments will depend on individual skin condition and goals.

Can I travel immediately after receiving Thermage FLX treatment?

Most patients can return to their normal activities right away, but it's best to plan your trip a few days later. In rare cases, some redness or swelling may occur, so it's better to avoid important events on the same day as your treatment.
