Keyhole lips, as the name shows up in clinic guides, usually means fuller lips with a small opening at the centre when the mouth is relaxed. Not a bigger pout. The gap.
Clinics don't even agree on where the filler goes for it. One guide talks about central fullness; another folds in outer-lip placement in the same write-up. So the word alone won't get you the same result twice.
If you're bringing it to a consult, say what you see — the open space in the middle — and ask whether that fits your lip line. Side photos help more than a front-only selfie here.
LookPrep keeps a guide to the keyhole lip shape with demo faces you can point at, so you don't have to invent the description on the spot. Shape reference, not a promised result.
