Vertical Lip Wrinkles and Their Causes

Fine lines above the lip prompt a lot of treatment pitches. The useful questions are what they are, and what to ask before treating them.
Can lip lines wait?
Nothing about a line above the lip sets a deadline, which frees you to read first and decide later.
What they are
The site my.clevelandclinic.org states that lip lines are vertical wrinkles that develop along and above your upper lip. The definition names the feature without promising a single cause or a single fix.
Reading before treatment
PMC hosts a paper titled Perioral rejuvenation: restoration of attractiveness in aging females by minimally invasive procedures. The American Society of Plastic Surgeons has its own page on Dermal Fillers. Read both before a consultation so you can judge what a clinic is pitching.
When to stop researching and ask a person
Reading is the safe part to do alone. If you are weighing any injectable, the decision belongs in front of a licensed clinician. Ask about side effects, what can be undone and what cannot.
