How long does the filler last?

It is complicated… The chemistry of the filler used, the mobility of the injected area, and individual characteristics play a significant role in the duration of the effect. Speaking of the most commonly used hyaluronic acid fillers, a few years of effect can be expected for nose fillers, 1 year for lip fillers, and 1-2 years for mid-face and cheek fillers. Although the amount of filler has significantly decreased after these periods, complete dissolution is not the case.
