Smile lines respond best to dermal fillers, with effects lasting six months to a year, though Botox, retinoids, and skin-tightening procedures also help.
Smile lines around the mouth are the nasolabial folds that run from your nose to the corners of your lips, plus the fine perioral lines that form above the upper lip. Deciding how to treat smile lines around the mouth comes down to one thing: what causes them. Volume loss, muscle movement, and skin laxity each need a different approach, and the right fix depends on which one you’re dealing with.
Which Treatment Matches Your Smile Line Type?
Dermal fillers are the main FDA-regulated option for nasolabial folds and lines around the mouth.
Cleveland Clinic lists four common filler materials doctors use:
- Hyaluronic acid — a gel that plumps skin and draws in moisture
- Polylactic acid — stimulates your own collagen production over time
- Calcium hydroxylapatite — a thicker filler for deeper folds
- PMMA microspheres — tiny beads that create lasting structure
Muscle-driven smile lines respond better to Botox-type injections, which relax the muscles that crease the skin with each smile. The trade-off: Botox may reduce fold appearance for only a few months, while dermal fillers typically last six months to a year.
Not every filler works for every facial area. The FDA approves each product for specific zones, so product matching matters more than a generic “smile line” label.
Your clinician should match the product to your exact concern, since some smile-line treatments fall outside a product’s approved label.
Avoid any provider offering this.
Non-Injectable Options and At-Home Care
For mild lines or maintenance between procedures, topical retinoids help by accelerating cell turnover and boosting collagen. Skin-tightening devices and surgical lifts address laxity when sagging, not volume loss, drives the folds.
If you want to try facial exercises, Cleveland Clinic recommends: separate your lips slightly, pull mouth corners backward toward the neck with fingers, keep lips parallel, hold 10 seconds, relax, and repeat 10 to 25 times.

FAQs
How long do smile line treatments last?
Dermal fillers typically last six months to a year, per Cleveland Clinic. Botox-type injections may reduce nasolabial fold appearance for only a few months. Topical retinoids require ongoing daily use, and their effects build gradually over weeks.
Are smile line fillers safe?
Not every filler is approved for every zone.
Can I remove smile lines naturally?
No at-home method can erase established nasolabial folds. Facial exercises may modestly strengthen underlying muscles, and retinoids improve skin texture over months, but volume loss—the main driver of smile lines—requires injectable fillers or procedures that stimulate collagen.
