Influencers like Kylie Jenner and the rest of her famous family have helped to make the use of facial fillers increasingly common. The more we’re bombarded with photos of perfectly plumped pouts on social media, the more we wonder: Is there such a thing as too much? If so, what does that mean?

Enter “filler fatigue,” a buzzy beauty term to describe what happens when someone has had too much filler. Essentially, over time, filler stretches and weighs down the skin, which means you need more filler with each trip to the doctor, which will just stretch the skin and tissue even more.
