Smoker's lines are perioral lines formed or accelerated by repeated lip pursing and collagen damage. They're among the most challenging perioral concerns to address — and require more than a single treatment.
get startedSmoker's lines are perioral lines — vertical lines radiating from the lip border — that have been formed or accelerated by the combined effects of repeated lip pursing and, in smokers, the direct collagen-damaging effects of tobacco exposure. The term is used both for lines in current or former smokers and for patients who've developed similar lines from other repetitive pursing behaviors. They tend to appear earlier, run deeper, and be more numerous than typical perioral lines.
Patients come in about smoker's lines when the perioral area has become one of the most aging parts of their face. The lines often run deeper and are more numerous than typical perioral lines, and they can make the mouth area look significantly older than the patient's age. Current or former smokers sometimes come in expecting that nothing can help. It can.
Smoker's lines have the same root causes as perioral lines, with smoking adding additional accelerating factors.
Repeated lip pursing: The primary mechanical driver — the orbicularis oris contracts with every puff, straw sip, or pursing motion, repeatedly compressing the skin above and below the lip.
Nicotine-induced vascular constriction: Smoking reduces oxygen delivery to skin cells by constricting blood vessels, accelerating the collagen breakdown that makes lines permanent.
Chemical free radical damage: The compounds in tobacco smoke generate free radicals that directly degrade collagen and elastin in the perioral skin, compounding the mechanical damage from muscle contraction.
Volume loss: The same age-related lip thinning and perioral fat pad deflation that drives perioral lines in non-smokers — simply accelerated.
Patients presenting with smoker's line concerns typically describe:
Smoker's lines can appear in the late 20s or early 30s in patients who smoke heavily, significantly ahead of the typical perioral aging timeline. The progression is faster and the lines tend to reach static depth sooner.
In non-smokers who develop similar lines from pursing habits, the progression mirrors perioral lines — dynamic in the 30s, increasingly static through the 40s and into the 50s.
For former smokers, stopping prevents further acceleration but doesn't reverse existing collagen damage. The skin retains the structural deficit from prior exposure, which is why patients who quit often find the lines persist or continue to become more visible as surrounding tissue ages normally.
Treatment for smoker's lines follows the same framework as perioral line treatment, often with greater intensity.
At CAMI, we treat smoker's lines as an advanced version of perioral line treatment. The same principles apply — address the muscle, restore the structure, improve the skin surface — but the degree of intervention required is often greater. Established smoker's lines typically have a resurfacing component in the protocol that milder perioral lines might not.
We also have an honest conversation with patients about expectations. Deep, established smoker's lines can be significantly improved but may not fully resolve with non-surgical treatment. The goal is meaningful, natural-looking improvement — lines that are less visible at rest, a perioral area that reads as refreshed, not erased.

Care guided by experience, precision, and a deep understanding of natural beauty.
