Hello Intellectual887537! My name is Jessica, I am a physician assistant, and one of the providers at Shah Facial Plastics. This is a great question. With dermal fillers, there are certain things that patient's cannot control including metabolism. Patient's with higher metabolisms will experience shorter filler results because their bodies will break the filler compound down faster than those with slower metabolisms. However, a great way to prolong your fillers is to not put them under stress or pressure. I recommend patient's to sleep on their back, as this removes pressure that will dissipate and agitate the filler. Be gentle with your skin, and don’t scrub or push on your face during your skincare routine. When you move and poke fillers, they will break down faster, so the more delicate you are with your fillers, the longer they will last. I hope this helps and best of luck!
