Demand of Body Fillers

I'm looking for enough product and I'm open to different types depending on what's suitable for my needs.
I'd like to explore hyaluronic acid fillers, as I've heard they are commonly used. Can you provide details on the available brands, their specific characteristics, and the pricing for hyaluronic acid fillers?Can you also tell me about the expected duration of results and any possible side effects associated with hyaluronic acid fillers?
Quantity: 16500 units
Thank you
