Why do some doctors recommend coming back for lip fillers every 3-6 months when others say they should last 9/12 months?

Filler longevity is variable. Factors that influence it include: filler selected, area treated, and patient metabolism. Certain fillers are designed to last longer than others. Those created specifically for the lips tend to not last as long because they are thinner to give them a more natural feel. Filler to the lips also may not last as long as other treated areas just because the lips are very dynamic. Filler longevity varies patient to patient as some patients metabolize the product more slowly than others.
Injectors encourage patients to return for more filler once they feel they no longer have the desired look. This too varies from patient to patient as some prefer a very full look while others want a subtle enhancement.

The variation in recommendations for the frequency of lip filler treatments can be attributed to several factors, and both viewpoints can be accurate depending on individual circumstances:

Individual Metabolism: The rate at which your body metabolizes hyaluronic acid fillers like Juvederm can vary. Some individuals may find that their body breaks down the filler more quickly, necessitating more frequent touch-ups every 3-6 months, while others may experience longer-lasting results.

Desired Outcome and Maintenance: For some patients, maintaining a very specific lip volume or shape may require more frequent visits. After achieving the desired outcome, maintenance sessions can often be spaced further apart, typically every 9-12 months.

Amount and Technique: The initial volume of filler used and the technique applied can impact how long the results last. If smaller amounts are used, or if the filler is placed in areas with higher movement (like the lips), it may dissipate more quickly.

Type of Filler Used: Different formulations of fillers can have varying longevity. Juvederm has different products within its range, each designed for specific areas and durations. Discussing which specific product was used can clarify expectations.

Doctor's Experience and Philosophy: Different practitioners may have varying philosophies on treatment frequency based on their clinical experience and patient feedback. Some may prefer more frequent, smaller adjustments to maintain optimal results, while others may recommend waiting longer to allow the full effects of the filler to be appreciated.

Ultimately, the most accurate recommendation will depend on your personal experience with fillers, your aesthetic goals, and the advice of a trusted and experienced provider who understands your individual needs. It’s always beneficial to have a detailed discussion with your practitioner about your expectations and the best plan for maintaining your results.
