Upper Lip Lines

Fine vertical lines above the upper lip are something many patients notice gradually, often when lipstick starts to bleed, makeup begins to sit in the lines, or they become more noticeable in photos. Whether you know them as smokers’ lines, barcode lines or lipstick lines, these perioral wrinkles are a very common concern I see in clinic.

What Are Upper Lip Lines? 

 

Upper lip lines are the fine vertical creases that form on the skin between the upper lip and the nose. You may know them as smokers’ lines, barcode lines or lipstick lines, as they can cause lip products to feather into the surrounding skin. The medical term is perioral lines, meaning lines around the mouth. The skin above the upper lip is particularly thin and delicate, and more susceptible to sun damage. It has fewer oil glands than much of the face, less underlying fat, and it moves constantly throughout the day as you talk, eat, drink and make expressions.

 

Because of this, the area can start to show signs of ageing earlier than other areas of the face. Over time, collagen and elastin levels decline, meaning the skin becomes less able to support itself and lines start to form and deepen. Repeated muscle movement, combined with environmental factors such as UV exposure, gradually contributes to the development of these lines.

 

In some people, these lines can appear earlier or become more noticeable due to naturally thinner skin and lower levels of structural support in this area. Hormonal changes over time can also influence collagen and elasticity, which may make lines appear more defined.

What Causes Upper Lip Lines?

Upper lip lines usually develop as a result of natural ageing combined with everyday movement and environmental factors. Smoking is often associated with these lines, but it is only one of several contributing factors. Understanding what is driving your lines helps me choose the safest and most effective treatment approach for you.

 

The most common causes include: 

 

- Natural ageing and collagen loss, which gradually thins the delicate skin around the mouth 

 

- Changes in underlying bone structure over time, reducing support for the upper lip and allowing lines to deepen 

 

- Repeated lip movements, such as talking, drinking through straws, smoking, whistling or pursing the lips 

 

- Cumulative sun exposure, which breaks down collagen and elastin in this thin, exposed area. Living on the Wirral coast can add to this, with reflected UV and drying sea winds 

 

- Genetics, which influence how early lines appear and how they progress 

 

- Dehydration and reduced barrier function, which can make lines appear more noticeable 

 

- Smoking, which accelerates collagen breakdown, reduces blood flow to the skin and involves repeated pursing of the lips

Types of Upper Lip Lines

Superficial Fine Lines 

 

These are often the earliest signs. Delicate surface lines may only be visible in certain lighting or when you purse your lips. They tend to respond very well to treatments that improve hydration and stimulate collagen, and treating them at this stage often means less intervention is needed, with more subtle, natural-looking results.  

 

Vertical Barcode Lines 

 

These are the classic vertical lines running from the edge of the lip (the vermillion border) upwards towards the nose. They develop over time due to repeated movement of the orbicularis oris muscle, which is the circular muscle around the mouth responsible for movements like pursing the lips. Although often associated with smoking, they are very common in non-smokers too, particularly in those who frequently purse the lips, such as when using straws or playing wind instruments.

Deep-Set Creases

 

As lines become more established, they can deepen and remain visible even when the face is at rest. At this stage, the skin has less structural support, and a more considered, combination approach is often needed to soften the lines while maintaining a natural result.  

 

Crepey Perioral Skin

 

Some patients notice a more general change in the skin rather than distinct lines, with a thin, finely wrinkled or “papery” texture. This usually reflects collagen loss, sun damage and reduced hydration. In these cases, the focus is on gradually improving overall skin quality rather than treating individual lines.

Frequently Asked Questions About Upper Lip Lines

Dr Rachel answers your most common questions about Upper Lip Lines

Why do I have smokers’ lines if I have never smoked?

The term “smokers’ lines” can be misleading. These lines develop from repeated lip movement combined with natural ageing, sun exposure and thinning of the delicate skin around the mouth, rather than smoking alone. Everyday actions such as drinking through straws, whistling, playing wind instruments or simply having naturally thinner skin in this area can all contribute. Many of my patients have never smoked and still develop upper lip lines. They are a very common part of the ageing process, and often one of the first areas patients start to notice changes.

How long do upper lip line treatments last?

Results vary depending on the treatment used and on your individual skin. As a general guide: 

• Dermal fillers: usually last around 8 to 12 months in the perioral area 

• Skin boosters and polynucleotides: typically last 6-9 months 

• Anti-wrinkle treatment: usually lasts around 2 to 3 months in this area, as the lips are very active 

• Bio-stimulators such as JULÄINE™: results develop gradually and can last up to 2 years In many cases, combining treatments gives the best and longest-lasting results, as different treatments work at different levels of the skin. I will guide you on the most appropriate approach for you, with a focus on subtle, natural-looking improvement over time.

Will treatment stop my lipstick from bleeding?

In many cases, yes, and it can make a real difference to how you feel day to day. By softening the vertical lines and improving skin quality around the mouth, there are fewer channels for lipstick to settle into, so feathering becomes much less noticeable. The aim is always improvement rather than perfection, but many patients tell me they feel more confident wearing their favourite lip colours again, without needing to worry about them bleeding into the surrounding skin.

Is treatment for upper lip lines painful?

The lip area is sensitive, but most patients find treatment very manageable. I use numbing cream where appropriate, gentle technique and very fine needles to keep you comfortable. You may feel brief pressure or small pinpricks, but discomfort is usually short-lived.

At what age should I start treating lip lines?

There is no perfect age. The right time is when the lines begin to bother you. Early, gentle treatment can help prevent fine lines from becoming deeper over time, often with simple skin-quality treatments and good homecare. That said, it is never too late. Meaningful improvement is possible at any stage with the right, carefully planned approach.

Will I still be able to smile and talk normally?

Absolutely. My aim is always to soften lines while preserving natural movement. The area around the mouth needs careful technique and conservative dosing, and I plan treatment very precisely so your speech, smile and everyday function feel normal. Choosing an experienced medical practitioner is especially important for this delicate area.

Will treating lip lines make my lips look bigger?

No. The aim of treating upper lip lines is to soften the lines, not to enlarge your lips. I use very small, carefully placed treatments to support the skin around the mouth while keeping your lip shape natural. If you ever did want more volume, that would be a separate discussion, but many patients are relieved to find we can improve lip lines without changing the look of their lips.

Can I prevent upper lip lines from getting worse?

Ageing cannot be stopped, but you can slow the progression of upper lip lines. Daily use of a broad-spectrum SPF is essential, even on cloudy Wirral days, as UV exposure is one of the main drivers of these lines. Gentle, consistent skincare that supports hydration and protects the skin barrier can also make a noticeable difference. Where possible, try to minimise repeated pursing of the lips, such as drinking through straws, and if you smoke, stopping can significantly reduce further line development. Maintenance treatments can then help preserve results over time, keeping the area smoother and more refined in a natural way.
