Key Points
- Smokers lines are the fine vertical creases above the upper lip. They are also called lipstick lines, vertical lip lines, upper lip lines, barcode lines or, clinically, perioral wrinkles — all the same thing.
- You do not have to smoke to get them. The name is misleading. They are driven by orbicularis oris muscle activity, thin skin with few oil glands, sun damage and collagen loss. Smoking accelerates all of it but is not required.
- The skin here is among the thinnest on the face and has very little subcutaneous fat, which is why lines etch in earlier and deeper than elsewhere.
- Anti-wrinkle injections have a genuinely limited role. Doses must be tiny — the same muscle closes the lips, so over-treatment affects drinking from a cup, whistling, and speech sounds. This is not the main answer for most people.
- Fine, etched lines respond best to resurfacing (laser or radiofrequency microneedling) that rebuilds collagen, not to filling.
- Deeper, longer lines may need a small amount of filler placed carefully — but overfilling here produces a distinctive shelf above the lip that is more ageing than the lines were.
- Where the upper lip has lengthened and thinned with age, a lip lift addresses the underlying structure rather than the surface.
Smoker’s lines — also called perioral lines, lipstick lines, or barcode lines — are the fine vertical wrinkles that develop above the upper lip. They’re called smoker’s lines because smoking accelerates their formation, but they appear in non-smokers too, and they’re one of the more challenging areas of the face to treat well.
This guide covers the anatomy that produces them, why they’re harder to treat than wrinkles elsewhere, and the realistic options at each stage — from skincare through to lip lift surgery.
Smokers Lines, Lipstick Lines and Vertical Lip Lines: The Same Thing
If you have searched for this you will have met several names for one problem. Smokers lines is the common term. Lipstick lines is used because lipstick bleeds into them. Vertical lip lines, upper lip lines and barcode lines all describe the same vertical creases running from the lip border up towards the nose. Perioral wrinkles is the clinical term — peri (around) and oral (mouth).
One more piece of terminology worth clearing up: when people look for an injectable treatment for smokers lines, what they usually have in mind is botulinum toxin. In the UK it is a prescription-only medicine, which means clinics are not permitted to advertise it by brand name. When you see a clinic offering “anti-wrinkle injections”, that is the same class of treatment described in the way the regulations require. Whether it is the right treatment for your lines is a separate question, and one we answer honestly below.
The anatomy
The muscle responsible is the orbicularis oris — the circular muscle that surrounds the mouth and controls every lip movement: speaking, kissing, eating, drinking through a straw, whistling. Unlike most other facial muscles, it doesn’t attach to bone — it sits in a sphincter pattern around the mouth, with its fibres inserting into the skin directly.
This anatomy explains two things about smoker’s lines:
Why they form so consistently. The orbicularis oris contracts many thousands of times a day in normal use. Every contraction folds the overlying skin radially toward the lip. Combined with the very thin skin in this area, the lines etch in quickly.
Why anti-wrinkle injections are tricky here. The orbicularis oris controls essential functions — speech, eating, drinking, kissing. Over-relaxation produces difficulty with these activities. Doses used in this area must therefore be very small, and the technique is more demanding than for upper-face treatment.
What Causes Smokers Lines? (Including in Non-Smokers)
Repetitive lip movement is the underlying mechanism. Anyone whose lips are active — speakers, singers, wind instrument players — develops perioral lines over time.
Smoking accelerates the process in two ways: the pursing action of inhalation adds mechanical wear above the baseline, and the chemical effect of smoke directly degrades dermal collagen and impairs blood supply to the skin. Long-term smokers consistently develop deeper, more etched perioral lines than non-smokers.
The evidence for this is unusually clean, because it comes from twin studies — which hold genetics constant and isolate what lifestyle actually contributes. An assessment of 67 pairs of Japanese identical twins using standardised photographic analysis found that within a pair, the twin who smoked showed significantly higher facial texture and wrinkle scores than the twin who did not, despite identical genes and the same age. That study measured cheek skin rather than the upper lip specifically, so it speaks to facial skin ageing generally rather than to perioral lines alone (Journal of Cosmetic Dermatology, 2014 ↗). A larger Danish twin study of 1,826 people aged over 70 assessed perceived age from photographs and found the significant determinants differed by sex: in men, smoking and sun exposure were both significantly associated with looking older than their years, while in women the significant factors were low body mass index and social class rather than smoking (Age and Ageing, 2006 ↗).
The practical reading of that: if you smoke, stopping will not reverse the lines you already have, but it removes the accelerant. And if you have never smoked and have these lines anyway, the same studies are reassuring — a substantial share of facial ageing is genetic and mechanical rather than behavioural, and the name of this feature is doing you a disservice.
UV exposure is the second largest modifiable factor. The upper lip area takes significant UV without much natural protection.
Sleep position. Patients who consistently sleep face-down or with one side of the mouth pressed into the pillow develop asymmetric perioral lines.
Volume loss. As the lips and surrounding area lose volume with age, the skin above the lip slackens and the lines deepen. Volume loss in the lip itself shortens the lip vertically, exaggerating the lines above it.
Loss of the white roll and Cupid’s bow definition with age contributes to the area looking less crisp overall.

Smokers Lines Treatment: What Actually Works
Skincare and lifestyle
The baseline interventions are the same as for facial ageing in general but matter particularly here:
Stop smoking — this is the single highest-impact intervention if you’re a current or former smoker. Existing lines won’t disappear, but progression slows substantially.
Daily broad-spectrum SPF applied to the upper lip area, including reapplication after eating or drinking.
Topical retinoids build dermal collagen and thicken the skin over time. Start low and build tolerance.
Vitamin C serum provides antioxidant protection and supports collagen synthesis.
A good lip balm with SPF in daytime reduces the constant mechanical wear from lip-licking.
These steps slow the progression of new lines but don’t reverse established ones.
Dermal fillers
For mild to moderate established lines, hyaluronic acid filler placed precisely into the lines themselves and into the upper lip border (the white roll) softens the lines and restores definition.
The technique varies based on what the patient needs:
Direct line filling uses very small amounts of soft, low-viscosity HA placed within each visible line. This requires a delicate hand and the right product choice — a soft, finely-tuned filler designed for superficial placement, not the more robust cheek fillers.
Lip border restoration places a small amount of filler along the vermilion border (where the lip meets the skin) to restore the natural ridge that fades with age. Improving the border indirectly improves how the lines above it read.
Lip volume restoration with lip filler can address the underlying lip thinning that exaggerates perioral lines. Modest volume restoration often improves the visual impact of the lines above without needing to fill them directly.
What to expect. Topical anaesthetic is applied for 15-20 minutes before treatment. The filler product contains lidocaine. The session itself takes 20-30 minutes. Mild swelling and possible bruising for 2-3 days afterwards.
Results last 6 to 12 months depending on the product and individual metabolism. The treatment can be reversed with hyaluronidase if needed.
Anti-wrinkle injections — small role, small doses
Very small doses of botulinum toxin into the orbicularis oris (1 to 2 units total, distributed across 4 points along the upper lip border) can soften the dynamic component of perioral lines — what’s sometimes called a lip flip. This relaxes the muscle just enough to reduce the mechanical wrinkle-forming action without compromising essential lip function.
The doses must be very conservative because the orbicularis oris controls essential daily activities. Over-treatment produces difficulty pronouncing certain consonants (P, B, M), difficulty drinking from a straw, asymmetric smile, or temporary numbness of feel. These effects resolve when the toxin wears off but are unwelcome in the meantime.
For this reason, AWI for the perioral area should only be performed by experienced injectors who know exactly how much is safe in this anatomically demanding location.
Energy-based treatments
For static lines that haven’t responded fully to filler, energy-based skin treatments stimulate collagen and improve skin quality:
Morpheus8 — radiofrequency microneedling reaches the deeper dermis and produces stronger remodelling. Recovery is 4 to 7 days. Particularly useful for the upper lip where skin texture has become crepey.
Laser resurfacing — including erbium and CO2 ablative laser — removes the top layer of damaged skin and stimulates significant collagen remodelling. Recovery is longer (10-14 days for ablative treatments), but the results for established perioral lines can be substantial. Often the right answer for patients with significant established lines who want a single treatment with a meaningful improvement.
Fotona 4D — combines four laser modes with no significant downtime. Useful for milder lines and as maintenance.
Multiple sessions are typically needed for non-ablative treatments; ablative resurfacing usually produces results in a single session.
Surgery — when the underlying issue is structural
For patients whose perioral concerns include lip thinning, lengthening of the upper lip with age, or descent of the lip corners, surgical treatment is sometimes more effective than continuing non-surgical maintenance.
Lip lift — a small surgical procedure that shortens the space between the nose and the upper lip and restores the upward curve of the lip. The procedure itself takes about an hour under local anaesthetic. Recovery is around 2 weeks, with sutures hidden at the base of the nose. The lift naturally reduces the area on which perioral lines etch and produces a more youthful lip position.
Facial fat transfer — the patient’s own fat is harvested, processed, and re-injected into the lips and perioral area. Unlike filler, the result is permanent for the fraction that survives transfer. Often combined with other facial work.
Mini facelift or full facelift — for patients with significant lower-face descent contributing to perioral and marionette line concerns. The lift repositions descended tissue and addresses the broader context of which perioral lines are one feature.
A consultation with our specialist team — including Dr Spyridon Vlachos — establishes which approach matches your anatomy and goals.
How to decide which treatment fits
Mild dynamic lines, visible during expression only: conservative AWI with a small dose into the orbicularis oris, plus daily SPF and good skincare.
Mild to moderate static lines: filler into the lines and along the lip border, plus lip filler if there’s volume loss contributing. Energy-based treatment as a complement if skin quality is a concern.
Established static lines with skin texture changes: energy-based treatment becomes the primary intervention. Laser resurfacing (erbium or CO2) is the strongest non-surgical option. Filler provides ongoing maintenance.
Significant perioral ageing with lip thinning, lengthening, or corner descent: surgical assessment. Lip lift addresses the structural changes that filler and laser can’t.
For most patients, combination treatment over time produces the best result — never relying entirely on one approach, and progressing through the stages as needed.
What we don’t recommend
Branded fillers as marketing tools. We use HA fillers chosen for their suitability for the specific area, not for brand recognition. Patients should be skeptical of clinics promoting specific filler brands as a selling point.
Microdermabrasion as primary treatment. The mechanical exfoliation it provides doesn’t reach the dermal level where perioral lines actually live. For superficial concerns, a topical retinoid produces more meaningful long-term benefit.
Aggressive chemical peels for established lines. These can produce significant downtime and pigmentation issues, particularly in patients with skin tones outside the lightest range. Energy-based laser treatment is generally a more predictable and controllable option.
Since peels come up constantly in this context, it is worth being specific about what the different agents do, because they are not interchangeable:
- Glycolic acid (superficial). An alpha hydroxy acid peel working at the level of the epidermis. It improves skin texture and brightness with minimal downtime, but does not reach the depth at which perioral lines are etched. Useful as skin maintenance, not as a treatment for the lines themselves.
- TCA, trichloroacetic acid (medium depth). Reaches the upper dermis and can make a genuine difference to fine perioral lines, at the cost of around a week of visible peeling and a real risk of post-inflammatory pigmentation in mid to deeper skin tones.
- Phenol (deep). Historically the most effective non-surgical treatment for deep perioral lines, and still occasionally used. It also carries the most significant risks — prolonged recovery, permanent loss of pigment producing a visible demarcation line at the jaw, and cardiac monitoring during the procedure because phenol is absorbed systemically. We do not consider it a first-line option when modern fractional lasers achieve comparable results with a more controllable safety profile.
The short version: superficial peels are too shallow to help, deep peels work but carry disproportionate risk for this indication, and medium-depth peels sit in a narrow band where laser is usually the better-controlled choice.
Cost
Filler for the perioral area is priced per syringe, with most patients needing 1 syringe for line and border work. Lip filler is usually a separate syringe if volume restoration is part of the plan. Laser resurfacing varies by depth and area. Surgical options (lip lift, fat transfer, facelift) vary substantially. Finance options through Chrysalis Finance are available, subject to status.
Common questions
What age do you get smokers lines?
They can begin to etch in from the late twenties, but most people do not notice them until the mid-thirties onwards, and they typically become a reason to seek treatment in the forties and fifties. The timing depends far more on skin type, sun exposure and how expressive the mouth is than on age alone — a fair-skinned outdoor worker who smokes may see them at thirty, while someone with thicker, darker skin who avoids sun may not until well into their fifties.
Can you get rid of smokers lines completely?
Fine lines can often be reduced to the point of being difficult to see, particularly with a proper course of resurfacing. Deep, long-standing etched lines are usually improved substantially rather than erased. Anyone promising complete removal of established perioral lines in a single treatment is overselling — and if the promise involves filler alone, be particularly cautious, because that is the route to an overfilled upper lip.
I’ve never smoked — why do I have these lines?
Smoker’s lines is a misleading name. The vast majority of patients with perioral lines aren’t smokers — they have lines because the orbicularis oris muscle works the same way in everyone. Smoking accelerates the process but isn’t required for it.
Why can’t anti-wrinkle injections solve this completely?
The dose required to fully relax the orbicularis oris would compromise speech, eating, and other essential functions. Conservative AWI helps with the dynamic component of perioral lines but doesn’t reverse static lines that have already etched into the skin. Combined treatment is almost always needed.
Can filler in my lip lines look obvious?
Yes — if too much is used, or the wrong filler is chosen, or if it’s placed too superficially, the result can look bumpy or unnatural. This is why the choice of filler product matters and why an experienced injector matters. Subtle results in this area require very small amounts of soft, low-G’ (softer) HA filler placed precisely.
How long after laser resurfacing will I see results?
Initial improvement is visible as soon as the surface heals (around 10-14 days for ablative treatments). The deeper collagen remodelling continues for 3 to 6 months — patients see the full result at that point.
If I’m planning a lip lift later, should I keep getting filler now?
Worth a specific discussion with your surgeon. Recent filler can complicate surgical planning, so most surgeons prefer at least 6 months between any HA filler treatment and surgery (or have the filler dissolved with hyaluronidase a few weeks before).
