I'm considering body fillers, but it's so hard to decide.

I've been debating about getting body fillers lately because of my body line, but it's hard to make a decision because of the dosage and the areas I need to treat. When I look at reviews, there are many people who got natural-looking results, but I'm worried that if I get too much injected, it might look unnatural. I've been looking into clinics in the Cheongdam area and reading recommendations for dermatology clinics there, but there is so much information that it actually feels more confusing...? Hahaha... I really just want to add volume naturally, so I was wondering what dosage would be appropriate for me?
