While lip filler is only temporary, lasting an average of 10-18 months, there are several things that you can do to help maintain your results. This includes: - Following the aftercare advice laid out by your lip filler specialist. - Avoiding exercise and alcohol for 24 hours after your treatment. - Wearing sunscreen every day (including a lip balm that has SPF protection). - Minimizing your stress levels wherever you can. - Eating healthily to avoid inflammation. - Using fillers that have a longer lifespan. - Scheduling regular top-up appointments.
