Summary
Absorbable barbed thread lifts offer safe and effective lower facial rejuvenation for Asian patients, improving laxity and contour. Longer threads demonstrated slightly better lifting results, though effects are temporary due to absorption.
Area of Science:
- Aesthetic Medicine
- Dermatology
- Plastic Surgery
Background:
- Asian patients seek lower facial aging treatments for enhanced projection and contour.
- The Definisse™ (Happy Lift™) thread lift uses barbed absorbable threads for tissue suspension and biostimulation.
- This study evaluates absorbable barbed threads for lower facial reshaping in Thai patients.
Purpose of the Study:
- To evaluate the efficacy and safety of absorbable barbed threads for lower facial reshaping in Thai patients.
- To compare the outcomes of two different thread lengths (12 cm and 23 cm).
Main Methods:
- Prospective, evaluator-blinded study with 27 Thai patients experiencing mild to moderate facial laxity.
- Thread implantation using a
Main Results:
- Immediate clinical improvement in facial laxity observed post-treatment.
- Significant volume improvement in the jawline, nasolabial folds, and submental area noted.
- Most patients (51.9%) reported excellent lifting effects by 1 week; all adverse reactions were mild and self-resolving.
Conclusions:
- Absorbable barbed thread implantation is a safe and effective facial rejuvenation method for Thai patients.
- Longer threads (23 cm) showed a slight superiority in lifting efficacy compared to shorter threads (12 cm).
- Visible lifting effects are temporary due to thread reabsorption starting around 6 months.
