Check whether the line shows up only when your face moves. If it does, Botox or another neuromodulator is the treatment to ask about first.
Fillers and Botox get mentioned together, so it is easy to treat them as one choice. Cleveland Clinic splits the question by the type of wrinkle.
Two kinds of wrinkle, two kinds of question
Cleveland Clinic says there are two main types of facial wrinkles. Dynamic wrinkles are caused by muscle activity seen with motion, such as crow's feet at the corner of the eyes or the lines on the forehead when you raise your eyebrows. Cleveland Clinic adds that dynamic wrinkles are best treated with Botox or another neuromodulator.
Read that as a directive. If your lines appear only while you squint, smile or lift your brows, say so at your consultation. If a line stays put while your face is still, that passage does not settle your case, so describe the line and ask which option applies.
Background reading on fillers and lips
General references help you arrive with better questions. OHSU's page on dermal fillers and UCLA Health's page on non-invasive facial rejuvenation are two places to start. Lip work has its own explainer, Cleveland Clinic's guide to lip augmentation, fat transfer and fillers.
The one thing to do first
Stand in front of a mirror, move your face, and note which lines move with you. Bring that note to your St. Augustine provider and ask them to name the type of wrinkle they are treating.
