"I want more Cupid's bow" can mean two different requests, and they usually lead to two different treatments.
If you want crisper peaks and a sharper outline, people tend to talk about a small amount of filler along the upper-lip border. If you want more of the upper lip to show at rest, the conversation is often about a lip flip, which relaxes the muscle above the lip and leaves the outline as it is.
Check your own photos smiling and at rest before the appointment. The difference often shows up there.
Here's how Cupid's bow filler compares with a lip flip, laid out as a short table. Only a provider who has examined you can say which, if either, fits.
