How many sessions do I need to see the effects of Sculptra?

Lately, my face feels like it has lost volume compared to before and my skin has become thinner overall, so I am looking into treatments that can improve both skin elasticity and volume.

Then I learned about Sculptra. I heard that unlike fillers that instantly add volume, it is a procedure that induces collagen production to gradually and naturally fill in the volume.

However, the more I look into it, the more questions I have.

In particular, I am curious whether I can feel some change after just one Sculptra treatment, or if I need to receive multiple sessions to see satisfactory results.

I would like to ask a few questions to those who have actually received it.

1. How many Sculptra treatments usually take to see noticeable results?

2. How long did it take you to feel the effects after the first treatment?

3. After the procedure, which aspect—facial volume or skin elasticity—did you feel the most satisfied with the changes?

4. How long did the effects last, and did you receive any additional treatments?

Also, I heard that the procedure is quite expensive, so I am curious about the total cost if I have to receive it multiple times.

For those who have tried it firsthand, please share your honest reviews on how many sessions you received and how satisfied you were with the cost-effectiveness!
