Inquiry regarding filler duration

I am an office worker considering procedures on my nose and chin to improve my plain appearance.

Since plastic surgery is scary and the cost is a burden, I chose fillers as a way to start easily.

My biggest concern is the duration of the filler. From what my friends tell me, the duration varies quite significantly depending on the product.

Generally, between domestic and imported products, which should I choose to maintain the filler's effects for a longer period?

I heard the procedure takes a short time, but I would be upset if it fell out quickly after just one injection.

I would appreciate it if you could also let me know the recommended number of sessions or touch-up intervals to ensure satisfactory results!
