Fillers are mostly temporary, and repeat injections are typically required every 1 to 2 years depending on the location injected and type of filler used.
While temporary, fillers do stimulate collagen production over time and can have a permanent softening effect on the tissue atrophy caused by the steroid injections.
It is worth a shot in the long run to attempt for some long term results, if not just for the short term filling effects.
