Can I compare various filler products in person during a consultation?

After looking into fillers, I found that there are various product names and different products are used at each clinic, so it is not easy to choose.

I would like to make a decision after hearing explanations of each product's features rather than just comparing prices. I am wondering if I can receive guidance on comparing various products during an actual consultation.

For those of you who have received the treatment, did you choose the product yourself, or did you decide based on a recommendation from medical staff after explaining the desired shape and area?
