Hello Interloper!

Some of these fillers have now been used on patients for around ten years and so there is a growing body of literature about their long-term effects.
As more and more patients are treated more information is also becoming available about potential unwanted effects.
The most common unwanted effects of the fillers are those that you would expect from any injection, particularly bruising where the filler has been injected. Redness and swelling are also quite common after filler injection and will usually settle down after a day or two.
