How does Thermage FLX work?

Thermage FLX represents a substantial new level of treatment for individuals experiencing mild to moderate symptoms of aging in the face, neck, and body areas. Thermage FLX can even treat the delicate eye area. This latest Thermage technology delivers more energy more efficiently and more comfortably to areas where you need skin rejuvenation.

Thermage FLX, like previous Thermage treatments, uses radiofrequency heat energy to gently heat the underlying skin layers in a controlled and targeted fashion. Heating the dermis in this way stimulates the production of collagen which is naturally produced by the body and is responsible for maintaining good skin tone, texture, and hydration. More collagen means healthier, younger looking skin.

How is Thermage FXL an improvement over earlier Thermage treatments?

Thermage FLX improves upon previous generations of the treatment in three crucial ways. First, a Thermage FLX treatment will be much more comfortable. The Thermage FLX treatment tip vibrates to improve patient comfort. Second, the all-new Thermage FLX treatment tip is now 25 percent larger which means more skin area can be treated during each treatment pass, reducing treatment times substantially.

What is the Thermage FLX procedure?

Since Thermage is not a laser, it heats only the deep layers of the skin and leaves the top layers cool.

No topical anesthetic is required, but we do recommend taking a dose of acetaminophen one hour before your treatment to improve your comfort level during the procedure. The new Thermage FLX tip will also help keep you comfortable during your treatment. Immediately after the procedure, your skin will begin to feel smoother and tighter. You will see the full effects by six months after your treatment. During this time, your body produces new collagen and rejuvenates your skin.

What is the recovery from Thermage FLX?

You will have no downtime following your Thermage FLX treatment. You can resume all activities right away. While you may experience mild redness immediately following the procedure, this will resolve quickly. Full results of your Thermage FLX treatment will be visible 6 months following your treatment.

What results can I expect from Thermage FLX?

Your Thermage FLX treatment will continue to improve your skin for two to six months after your treatment. During this time, your body continues to produce new collagen. Your results, however, will last much longer. You will enjoy firmer, younger looking skin. Individual results, however, will vary depending on many factors such as genetics, your overall health, and levels of sun exposure.

While only a single Thermage FLX treatment is needed to get your full results, follow-up treatments are recommended annually or as required to maintain your look, since aging will naturally continue to affect your skin.

We also recommend alternating Thermage FLX treatments with Ultherapy treatments to maximize the collagen boosting effect of both treatments. Thermage FLX is popular with both men and women and is safe for all skin tones and skin types.

Why choose us?

Double board-certified facial plastic surgeons Drs. Elbert and Jacqueline Cheng were instrumental in developing the Thermage treatment tip which is now used internationally to ensure efficient delivery of the most optimal amount of radiofrequency energy.

Thus, few surgeons have more experience or expertise in the uses and possibilities of the Thermage FLX device. Drs. Elbert and Jacqueline Cheng have not only perfected this and other related cosmetic procedures, but they actually train others in them, from future plastic surgeons to currently practicing professionals.

At Cheng Plastic Surgery, our double board-certified facial plastic surgeons approach each patient and procedure uniquely and spend ample time to fully understand and help achieve your own unique aesthetic goals.


What is Ultherapy and why should I consider adding it to my Thermage FLX treatment regimen?

Ultherapy is a non-invasive cosmetic procedure that uses ultrasound to penetrate the upper levels of skin to the lower levels and stimulate the body’s production of collagen. Similar to Thermage FLX, it is highly precise and targets only the selected treatment site(s). The procedure takes 30 – 90 minutes, depending on the area(s) to be treated, and there is no downtime afterward. Like Thermage FLX, it does not affect any surrounding tissue. There is no heat applied to the surface of the skin.

Because everybody is different, people may respond differently to various techniques and technologies, so alternating therapies may produce the best results for you. We do offer Ultherapy at Cheng Plastic Surgery , and Dr. Dr. Elbert and Dr. Jacqueline will be glad to discuss the possibility of using Ultherapy in your treatment program.

Our goal is always to present you with options for the procedures that will help you achieve your goals to look and feel your best.

Practice Policy Update from Cheng Plastic Surgery Regarding COVID-19 View Update Virtual Consultation

Practice Policy Update Regarding COVID-19

Monday, January 4, 2021:

We are open!

We cannot wait to see all of our amazing patients in our office! We are currently working with a more limited schedule than before, so please be patient as we navigate through this, together.

There are a few key changes we’ve made to our appointment protocol to ensure we are maintaining social distancing and following strict COVID-19 health and safety protocols - for you AND for us.

  1. Call our office from your car once you’ve arrived for your appointment. A staff member will come out to greet you, take your temperature and conduct a short COVID-19 health screening to make sure you are in good health prior to entering the building. Our doors will remain locked during normal business hours to ensure only those who have been screened can enter.
  2. Please arrive at your appointment wearing a mask or protective face covering. We will not be able to bring you inside the office without one.
  3. We will not have more than one patient in the lobby at a time.
  4. You will be greeted by Dr. Elbert or Dr. Jacqueline wearing their Personal Protective Equipment deemed necessary by your specific treatment. (N95 mask, gloves, face shield or protective eyewear, etc.) We ask that you leave your mask on during the procedure, and only take it off if necessary to complete the treatment.
  5. All necessary transactions will be done in the room your treatment is being performed. This will avoid unnecessary back ups in the lobby.
  6. You will then be walked out through the back door of the office. This is the best way to keep all staff and patients socially distanced while maintaining one steady flow of traffic throughout the building.

And of course, all rooms will be heavily disinfected immediately after you leave just as we have always done prior to the pandemic. Each room is equipped with an air filter as an added safety measure. We will place a major focus on high-contact areas such as chairs, doorknobs, counter tops, mirrors and more.

We are still continuing to conduct Virtual Consultations if you prefer a quicker and no-contact experience.

Virtual Consultation

For the safety of our patients and staff, we ask that you reschedule your appointment and do not enter our office with any of the following conditions:

  1. You have tested positive for COVID-19 in the last 14 days.
  2. You have been in close contact with someone who has tested positive for COVID-19 in the last 14 days.
  3. You traveled more than 150 miles or have been in close contact with someone who has traveled in the last 10 days.
  4. You are experiencing any of the following symptoms:
    • fever or chills
    • cough
    • shortness of breath
    • fatigue
    • muscle or body aches
    • headaches
    • sore throat
    • loss of taste or smell
    • nausea, diarrhea, or vomiting

Concerned about getting the Moderna vaccine after having recently received filler treatment? In some studies, it has been observed that a small percentage of the vaccinated groups experienced localized inflammation (swelling) after receiving the Moderna COVID-19 Vaccine. In said cases, all studied reactions were temporary immune responses. It has been suggested that patients refrain from getting filler two weeks before and after the vaccine. If you have any questions, please feel free to call our office!

Thank you for your continued support and we can't wait to see you again!

Kindest Regards,,

Dr. Elbert, Dr. Jacqueline and staff at Cheng Plastic Surgery
