Lately, the shadows under my eyes look particularly dark in photos, so it's really bothering me.

I'm looking for a place that specializes in under-eye fillers, and I'm wondering if they just add volume.

I've seen a lot of reviews saying that their entire appearance changed after getting the procedure.

Does it actually help to alleviate the look of dark circles as well?

I'm also curious if it looks awkward when smiling or if the fillers are noticeable.
