The rate of metabolism of hyaluronic acid filler varies from person to person.

Premium fillers such as HYAcorp will tend to last longer than Economy fillers.

The results of bum injections are immediate, with the results usually fading from 9 to 18 months following the procedure.

The procedure will need to be repeated again in 9-18 months’ time, possibly requiring less filler on subsequent visits.

Patients returning for injections after 9-18 months typically require around half, or more, of the volume they received in their original procedure, to maintain their increased buttock volume.

Natural weight loss, or weight gain, may add to, or subtract from, the amount of filler required to stay the same size.
