I have done lip filler and chin filler on 4th July 2021. I thought the clinic was using Juvederm, but that was not the case. I found out they used nexfill filler instead. I would like to top up, the plan was to build the shape one bit at a time, however this time i want to go to a different clinic and use only Juvederm. Is it safe to do it now only a few months after or do i need to give more time between different fillers? Much appreciated for any type of advice.
