I'm looking into body fillers for my shoulders and hips, but there are so many clinics that it's hard to decide.

When I search online, everyone claims to be good at body fillers, but I don't know what the truth is lol. I'm wondering if looking only at before and after photos is the right approach when searching for a good place, or if I should get consultations at several different clinics.

Also, when choosing a clinic specializing in body fillers, are the director's experience or the products used important?
