Korea: A new survey-based study published in the Journal of Drugs in Dermatology provides updated real-world insights into the use of Thermage FLX, highlighting its growing acceptance as a non-invasive option for skin tightening and rejuvenation.
The study, led by Dong Hye Suh from ArumdaunNara Dermatologic Clinic, Seoul, and colleagues, captures expert opinions across the Asia-Pacific region regarding the device’s effectiveness, safety, and clinical use patterns.
Thermage FLX is an advanced monopolar radiofrequency (RF) technology designed to improve skin laxity and visible signs of aging. By delivering controlled thermal energy into the dermis, the device stimulates collagen remodeling through the body’s natural healing response. Compared to earlier versions, the FLX system offers improved precision, faster procedures, and enhanced patient comfort, making it increasingly popular in aesthetic dermatology.
For this purpose, the researchers conducted a cross-sectional survey involving 204 physicians from eight Asia-Pacific countries, including Korea, Taiwan, China, Thailand, Vietnam, Singapore, Malaysia, and Australia. All participants had at least one year of experience using Thermage FLX. The survey, consisting of 29 multiple-choice questions, explored three major areas: perceived effectiveness, complications, and clinical practice trends. On average, respondents had nearly eight years of experience with Thermage and over three years specifically with the FLX platform.
The following were the key findings:
- Individuals in their 40s with mild-to-moderate skin laxity were identified as the most suitable candidates.
- Skin thickness and age-related changes, including wrinkling, were key factors influencing treatment outcomes.
- Additional benefits beyond skin tightening included improvements in enlarged pores, rosacea, and acne.
- Nearly 70% of clinicians reported low non-response rates, with fewer than 20% of patients not showing improvement.
- Some physicians observed higher non-responder rates, highlighting the need for realistic patient expectations.
- Combination approaches, particularly with injectables, were commonly used to enhance results.
- Many practitioners performed Thermage FLX and injectable treatments on the same day.
- The Thermage Eye Tip is increasingly used for non-invasive eyelid tightening without downtime.
- Eye treatments were often combined with injectables, especially for crow’s feet, with RF performed first.
- The procedure demonstrated a favorable safety profile overall.
- Common side effects included mild redness, swelling, and occasional vesicle formation.
- Serious complications were rare.
- For eye treatments, additional effects such as dryness and transient visual disturbances were reported.
- Pain management was most commonly achieved using topical anesthetic creams.
- Nitrous oxide is emerging as an alternative option for pain control.
Physicians’ personal experiences further supported the treatment’s effectiveness, with high satisfaction rates reported among those who had undergone the procedure themselves. Most favored annual treatment intervals, although some opted for shorter gaps depending on patient needs.
Overall, the study reinforces Thermage FLX as a reliable, non-invasive solution for skin rejuvenation. With consistent outcomes, high physician satisfaction, and a strong safety profile, the findings offer practical guidance for clinicians aiming to optimize treatment strategies in aesthetic practice.
