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 of fillers varies quite a bit 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'm worried it would be a waste if it just falls out quickly after getting it once.

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