I have a very weak small chin , feeling low about myself for years but now I want fillers , how long does it last ? does Bella fill come with con's ? Since it's long lasting (5 years ) apparently does it have any side effects I should be aware of also is it too expensive to keep doing ? Usually how many syringes does a receding chin need do I just start with the regular chin fillers like voluma but it's very short lasts only about 6 months ? Thank you
