Tighten And Rejuvenate Skin With RF Thermalift FLX At SL Aesthetic Clinic Singapore

As you age, your skin naturally loses firmness and elasticity. If skincare alone hasn’t been enough to address these changes, many patients explore professional skin tightening treatments as the next step. 

One popular option is RF Thermalift FLX, a non-invasive, non-surgical radiofrequency treatment designed to tighten loose skin, smooth fine lines, and contour the face, eye area, and jawline.

What Is RF Thermalift FLX?

RF Thermalift FLX is an FDA-approved, non-surgical skin tightening treatment that uses monopolar capacitively coupled radiofrequency (RF) energy to firm and rejuvenate ageing skin. 

This monopolar RF technology heats the deeper layers of the skin and stimulates collagen production, kickstarting your skin’s natural collagen production. 

As new collagen develops, the skin gradually appears smoother, firmer, and more lifted.

Lifts and Firms Loose Skin

RF Thermalift FLX delivers heat deep into the skin to tighten lax areas, helping to lift sagging skin and better define the jawline and facial contours.

Smooths Lines and Refines Texture

As collagen rebuilds over time, it helps soften fine lines and wrinkles while improving pores, acne scars, and uneven skin texture.

Treats Face, Eyes and Body

Different handpieces allow precise treatment of delicate areas like the eyes (for mild hooding and crow’s feet), as well as larger areas such as the abdomen, arms, and thighs.

Long-Lasting Results in Fewer Sessions

Results continue to improve over 3 to 6 months and can last up to 2 years, often with just one session.

Benefits of RF Thermalift FLX

The primary benefits of the RF Thermalift FLX treatment include:

What Makes RF Thermalift FLX Different

RF Thermalift FLX is designed to deliver a more efficient and comfortable skin tightening experience. Its larger treatment tip allows more skin to be covered in a shorter time, helping to reduce overall treatment duration. At the same time, built-in AccuREP™ technology continuously adjusts the energy delivered with each pulse, ensuring consistent and precise results throughout the session. To improve comfort, the system also incorporates vibration and cooling features that help minimise heat sensation on the skin during treatment.

Which Skin Concerns Can RF Thermalift FLX Treat?

Crepey Skin & Eye Wrinkles

Smooths delicate skin and fine lines around the upper and lower eyelids.

Jowls & Jawline Sagging
Visibly firms loose skin along the lower face to improve jawline definition.
Texture & Pore Size
Helps smooth skin texture and reduce the appearance of open pores.
Collagen Loss
Helps stimulate collagen production over time for improved skin firmness.

Is RF Thermalift FLX Painful?

Many patients are concerned about discomfort before RF treatments. At SL Aesthetic Clinic, RF Thermalift FLX is designed to be as comfortable as possible while still effectively improving skin firmness and softening the appearance of wrinkles.

To ensure a smooth and comfortable experience, several strategies are used during the procedure:

  • Prescription topical numbing cream applied prior to treatment
  • Integrated cooling cryogen and gentle vibration to minimise pain signals
  • Optional oral painkillers and a relaxed clinical environment with light background music

RF Thermalift FLX & HIFU: Combining Skin Tightening Options

For comprehensive facial rejuvenation, RF Thermalift FLX can be paired with HIFU (High Intensity Focused Ultrasound) to address skin ageing at different tissue depths:

Treatment FeatureRF Thermalift FLXHIFU (High Intensity Focused Ultrasound)
Heating MechanismTop-down (Dermis & Subcutaneous layers)Inside-out (SMAS layer & deep fat layers)
Primary FocusSurface texture, pore size, fine lines, skin firmnessStructural lifting against gravitational sagging
Target AreasCrepey eyelids, fine facial wrinkles, loose skinSagging jowls, heavy lower face, deep structural support
When combined with HIFU, monopolar radiofrequency can help enhance skin tightening by targeting different layers of tissue, without the need for surgery. Other complementary procedures may include 6D Pro, RF Gold Microneedling, Ultherapy, thread lift, and dermal fillers depending on your specific treatment goals.

FAQ

RF Thermalift FLX is a non-invasive, non-surgical skin tightening treatment that uses monopolar capacitively coupled radiofrequency (RF) energy to penetrate into the dermis and subcutaneous tissues. It is in these layers where collagen is stimulated, resulting in the tightening of the skin.

RF Thermalift FLX is able to treat superficial skin concerns – wrinkles, pores, texture, dimples.

RF Thermalift FLX can be used to tighten skin and smoothen out wrinkles on :

  • Face, including eyelids
  • Neck
  • Hands
  • Thighs
  • And others

RF Thermalift FLX is FDA approved and is a safe and effective procedure when performed by a trained professional. Speak to our doctor to know more.

Depending on your skin condition, most patients see tighter skin, improved skin texture and tighter, firmer skin. Wrinkles are also smoothened, and delicate eyelid skin is strengthened for a more well-rested appearance.

After a RF Thermalift FLX treatment, your skin may feel taut and smooth to the touch. Additional tightening and smoothing may occur over 3 to 6 months.

After assessing your needs, the doctor can perform the treatment in approximately an hour for a treatment of the face (longer for the body), subject to the doctor’s schedule. Otherwise, a later appointment can be made for the procedure itself.

RF Thermalift FLX results can last up to two years. Results vary by the individual and lifestyle choices.

The saying ‘prevention is better than cure’ holds true here. Anti-ageing treatments such as lasers and RF Thermalift FLX can be used preventatively before your skin loses its collagen and elasticity. Waiting until your skin becomes significantly saggy or wrinkly means it will be much harder to treat, requiring a larger financial and time investment. Starting early, on the other hand, allows you to hold onto the collagen you already have, making it much easier to keep your skin looking youthful over time.

Because it is non-invasive, downtime is minimised with RF Thermalift FLX. You are free to return to daily activities immediately after treatment. Makeup can be applied immediately after the treatment session.

Some redness can be seen in patients after treatment, and generally disappears within several hours. Blisters, though rare, may appear after the procedure. Occasionally, mild swelling may be noticed after the treatment but resolves in two or three days.

As with all treatments, downtime varies by the individual.

RF Thermalift FLX is suitable for patients desiring a non-invasive method to improve their sagging or ageing skin. The procedure is suitable for all skin types, and for both men and women. As with all medical procedures, you should be sure to disclose all of your medical history and current habits such as smoking and use of blood-thinners, medications, birth control pills, or supplements.

RF Thermalift FLX may be unsuitable in the following circumstances:

  • Patients with unrealistic expectations, such as those who seek to reverse skin ageing and return to their younger self
  • Patients using a cardiac pacemaker or other active implants
  • People that are hypersensitive to heat
  • Overly sensitive skin conditions such as eczema
  • Recent chemical peel or dermabrasion
  • Pregnant women

Pre-care: Ensure that you’re in a good state of health and not recovering from a bacterial or viral infection. Please ensure that you’re well hydrated before the procedure.

Post-care: Avoid the consumption of alcohol, swimming, strenuous exercise and going to a sauna for a day.

 

No, stopping treatment will not make your skin look worse or sag faster than before.

While ageing, gravity, and UV exposure will naturally cause skin to sag over time, making skin tightening treatments part of your routine simply slows this process. If you decide to stop, your skin will still look better and firmer than someone your age who hasn’t done any collagen-stimulating treatments, thanks to the extra collagen and elastin built up during your sessions.

Following your RF Thermalift FLX procedure, you can do a basic facial 2 weeks after. For facials that involve machines (e.g. I2PL, M22), we recommend waiting 4 weeks. 

Most patients require only one session to see visible skin tightening results.

Unlike other energy-based procedures that require multiple treatments, RF Thermalift FLX delivers sufficient radiofrequency energy in a single sitting to trigger deep collagen renewal. Initial improvements appear within a few weeks, with full tightening and contouring results continuing to develop over 6 months.

To maintain these results against the natural ageing process, patients typically schedule a single maintenance session every 12 to 18 months.

Yes, RF Thermalift FLX is commonly used to treat loose skin and wrinkles on the neck.

Because the skin on the neck is naturally thin and prone to losing elasticity early, monopolar radiofrequency is ideal for firming this area without surgery.
