How long does a single lip augmentation (duck lips) last?
In general, the duration of plump lip injections varies depending on multiple factors. If hyaluronic acid is injected, the results typically last 6–12 months. Collagen injections usually last 3–12 months. Autologous fat injections can last 3–5 years. The exact duration depends on individual body conditions, type of injectable material, dosage, injection technique, and post-procedure care.
1. Individual Body Condition
Different people have varying physical conditions and immune systems, leading to different reactions to injectable materials. Those with faster metabolisms may experience shorter-lasting results, while individuals with slower metabolisms may enjoy longer-lasting effects.
2. Injectable Material
Commonly used materials for plump lip injections include hyaluronic acid, collagen, and autologous fat. Different materials have varying metabolic rates and durations of effect.
3. Injection Dosage
Injecting too much or too little material may lead to unsatisfactory results. It's important to communicate fully with your doctor beforehand to determine the appropriate dosage based on your individual needs.
4. Injection Technique
Experienced doctors can accurately inject the material into the lips to achieve a natural, full appearance. Poor injection technique may result in uneven lip contours, swelling, or other issues that affect both aesthetics and longevity of results.
5. Post-Procedure Care
Proper aftercare helps reduce swelling, promotes healing, and extends the duration of the results. Therefore, it’s essential to follow your doctor’s post-treatment instructions carefully.
