For those of you who have tried lip fillers, are you satisfied?

My lips are naturally on the thinner side, so when I take photos, they look like they barely exist. Even when I apply lip products heavily, they don't look as plump as I'd like, and I've always been disappointed because they look even thinner, especially when I smile. So lately, I've been seriously considering lip fillers, but now that I'm actually about to do it, there are quite a few things I'm worried about.

When I read online reviews, there are many people who say they became naturally prettier, but conversely, there are also comments saying it was too obvious or they didn't like the shape over time, so I'm confused about what is right. I don't want artificially plump lips; I just want a little natural volume that looks like my own lips. It would be even better if it also had the effect of making the corners of my mouth look slightly lifted.

I am curious about the typical starting dosage for the first injection and whether the pain is tolerable. I would also like to know how many days bruising or swelling lasts and if I can resume my daily activities immediately. Most of all, I am curious about how long the effects last. If the effects fade quickly within a few months, I am concerned about whether I should continue getting injections.
