Is filler the only solution for nasolabial folds? I'm curious if Rituo has no side effects and looks natural.

I only had wrinkles on one side, but now that they're appearing on the other, it's really bothering me.

It seems like it might be developing as I get older and my skin sags...

When I consult with doctors, they usually only recommend fillers, but I don't want to do them because I've heard they can cause lumps. I've also heard that Juvereign can cause nodules, while Ritu-O is supposed to be good. I'm wondering if those who have tried it are okay without any side effects, such as nodules or the absorption process.
