Over the age of 37, Ms. Vivian, an Australian living and working in Vietnam, began to notice slight sagging and a loss of firmness in her cheeks and jawline. While she wanted to improve her appearance, she was hesitant about surgery due to the fear of scarring and lengthy downtime. After careful research, she chose Thermage—a non-invasive rejuvenation and lifting solution—at Kangnam Saigon Aesthetic Hospital.
Note: Aesthetic results may vary depending on individual skin conditions and physical constitution.
At 37, Vivian was facing increasingly visible signs of aging on her face. Following an advanced skin analysis and a direct clinical evaluation by Dr. Thuy Le (Le Thi Thuy) – Head of Dermatology at Kangnam Saigon Aesthetic Hospital, her specific skin concerns were identified:
Based on Vivian’s actual skin condition and personal desires, Dr. Thuy Le prescribed a skin rejuvenation solution using Thermage FLX technology.
This is an advanced technology that utilizes monopolar Capacitive Radiofrequency (CRF) energy to deliver uniform heat deep into the epidermis, dermis, and subcutaneous layers of the skin.
This thermal energy immediately contracts loose, sagging collagen fibers while simultaneously triggering a natural response that stimulates the body to continuously produce new collagen and elastin cells over time. The entire process guarantees no peeling, no surface damage, and completely preserves the natural structure of the face.
The Thermage FLX treatment for Vivian was strictly performed in a sterile room at the Dermatology Department, following medical-standard steps:
Step 1: Skin Cleansing and Preparation
Vivian’s makeup was removed, and her facial skin underwent a deep cleanse. A topical numbing cream was then applied to ensure maximum comfort and relaxation throughout the procedure.
Step 2: Mapping the Treatment Area
Dr. Thuy Le used a specialized grid to map out the treatment area. This grid helps the doctor precisely allocate the number of shots and distribute energy evenly, preventing any missed spots or overlapping zones.
Step 3: Verifying the Authentic Tip
Before the procedure began, Vivian directly inspected the barcode and seal of a 100% brand-new Thermage FLX tip to ensure complete transparency, safety, and maximum efficacy of the equipment.

Step 4: Performing the Thermage FLX Procedure
Dr. Thuy Le directly operated the handpiece, continuously adjusting the energy levels to suit the varying thickness of each facial zone on Vivian’s face. With her high level of expertise, the doctor focused deeply on areas with significant laxity, such as the jawline, cheeks, and around the eyes. Thanks to the integrated cooling technology and the multi-directional vibration of the treatment tip, Vivian shared that she only felt a mild, deep warmth beneath her skin and remained completely comfortable.
Immediately after the 60-minute session concluded, Vivian was handed a mirror to check the instant results. The changes on her face were remarkably visible:
Sharing her experience, Vivian said:
“I was very surprised because the process was much faster and gentler than I imagined. Dr. Thuy Le was incredibly professional throughout the procedure, constantly checking in on how I was feeling while operating the machine.”
The results of Thermage FLX will continue to improve and reach their peak after 2 to 3 months, once the new collagen cells have fully regenerated, helping to maintain firm skin for the long term.
