Lip Fillers typically last 8-12 months, or longer.   Results may vary based on age, lip size, metabolism, smoking, sun exposure, injector technique, and amount of product used.   One syringe of Filler is often long-lasting for most patients. However, some patients may simply need more product to reach the desired result.   We recommend following up at 6-month intervals to evaluate your progress. Best results are observed with serial treatments or regular touch-ups.
