I am considering getting lip fillers.

My lips are naturally on the thinner side, so they look too flat in photos, and even when I apply lipstick, it doesn't quite give the look I envisioned. I am particularly self-conscious about the almost complete lack of volume in my profile, so I would like to add just a little bit of natural volume.

However, I am worried that getting too much lip filler might make it look unnatural or puffy. If anyone has actually had it done, I am curious about the pain, swelling, and duration of the results. I would also like to hear from those who had a natural-looking procedure!
