(Question) Is the Juvegen treatment effective for nasolabial folds?

I have severe nasolabial folds only on the left side. I'm not sure if it's because of my usual facial expressions or if I smile incorrectly, but it is much worse on only one side. Having these wrinkles makes me look older, and since my makeup tends to crease heavily, I am self-conscious about it every time I go out. While looking into Botox or fillers, I learned about the Juvegen procedure. I am curious if anyone has received Juvegen treatment for their nasolabial folds. What were the actual results like? How many sessions are needed to see effects? Were there any side effects? How long did the results last? And approximately how much did it cost?
