For long periods of time, fillers can stretch the tissues under the skin, which essentially speeds up the aging process “because those tissues aren't going to bounce the same way as you age,” Park Avenue facial plastic surgeon Andrew Jacono explained to HuffPost. Fillers add volume to poor areas by attracting water. However, the skin may stretch over time due to excessive use of fillers. But, when done properly, she says fillers should not stretch the skin but improve the area.
The results of the filling can never be predicted 100%, but having the right doctor, one who knows how the filler reacts on the body and really cares about the desired result, can help to avoid any negative side effects and give desirable results. And make sure that the filling has really disappeared, because the filling may never completely disintegrate. Putting unnecessary amounts of filler on the chin distorts the facial balance, making the lower third of the face look square rather than heart-shaped, which is associated with youth. The irony of all this is that fillers almost always age it because when exaggerated, the filler accumulates on the body, migrates out of the target area, leading to sagging and distortion.
Hyaluronic acid fillers were originally intended to give some facial fullness to those who had lost volume due to extreme weight loss, drug use or illness. HA fillers last up to 18 months and, when dissolved, leave some collateral damage in the form of an inflammatory reaction to the filling and capsule formation. When more padding is placed than the body can hold in one place, the filling has to go somewhere and goes south, which causes sagging. Other options included permanent filling that was based on cement products and this combination of unnatural texture and having to wait for collagen injections meant that the filler wasn't as popular 15 or 20 years ago.
It takes months or years for the filler to dissolve (and sometimes the filler doesn't dissolve at all) and if you keep getting more and more injections, you just fill your face with more and more gel. Due to the low maintenance factor of most fillers on the market, some of the worst fears people have about long-term use of the filler are unfounded. A little padding may remain in place, but when the scale is tilted, which happens easily, the filling has to go somewhere.
