Smoker’s Lines Around the Mouth: Causes and Treatment Options

Fine vertical lines around the lips are a common concern as we get older. They are often referred to as smoker’s lines, lip lines or perioral lines, and they usually become most noticeable above the upper lip.

Despite the name, you do not need to be a smoker to develop them. I regularly see patients who have never smoked but have gradually noticed these lines becoming more visible.

At my aesthetic clinic in Warrington, one of the most important things I explain during consultation is that these lines do not have a single cause. The appearance of the area around the mouth is influenced by the skin, underlying tissues, movement of the muscles around the lips and the natural ageing process.

Understanding what is causing the lines is therefore important before deciding whether treatment is appropriate.

What are smoker’s lines?

Smoker’s lines are the fine vertical lines that develop around the mouth, particularly between the upper lip and the nose.

Initially, they may only appear when you purse your lips—for example, when drinking through a straw or making certain facial expressions. These are known as dynamic lines because they appear primarily with movement.

Over time, however, the lines can remain visible even when the mouth is completely relaxed. At this stage they have become more established or static.

For some people they remain very fine. For others, they can gradually become deeper and may affect the smoothness and definition of the lip border.

What causes lines around the lips?

Usually, there isn't one single cause.

The skin naturally produces less collagen and elastin as we age. This gradually makes it thinner and less resilient, allowing repetitive facial movements to leave more permanent lines.

The circular muscle surrounding the mouth—the orbicularis oris—is also extremely active. We use it constantly when speaking, eating, drinking and expressing ourselves. Years of repeated movement can contribute to vertical lines developing around the lips.

Other factors can include:

• natural ageing and loss of collagen;

• repeated movement of the lips;

• changes in facial volume and support;

• genetics;

• sun exposure and cumulative skin damage; and

• smoking, which can accelerate skin ageing as well as involving repetitive pursing of the lips.

This is why simply filling an individual line is not necessarily the most appropriate approach.

Can smoker’s lines be treated?

There are different ways of approaching perioral lines, and the most appropriate option depends on why the lines have developed, how deep they are, the quality of the surrounding skin and the result the patient would like to achieve.

Some patients primarily have volume loss and loss of structural support. Others have very fine lines associated more strongly with skin ageing. Some have a combination of several factors.

This is also why two patients who appear to have a similar concern may benefit from completely different treatment plans.

Dermal filler

Carefully placed hyaluronic acid dermal filler can sometimes be used to soften established lines and improve support around the mouth.

The aim does not have to be larger lips.

This is an important distinction because some patients avoid discussing lip lines because they are worried that filler will dramatically increase the size of their lips. In appropriate patients, treatment can instead focus on subtle support and refinement of the perioral area.

When treating this region, I generally favour a conservative approach. The mouth is a highly expressive part of the face, and excessive volume can easily change its natural proportions.

Lip enhancement and support

Sometimes the lines above the mouth are part of a wider change in the lips themselves.

As we age, the lips can gradually lose volume, projection and definition. Supporting the lip appropriately may therefore form part of the treatment plan rather than simply injecting each visible line.

Again, the objective is not necessarily to create visibly fuller lips. For many patients, the goal is simply to restore some of the support that has gradually been lost.

Anti-wrinkle treatment

In selected patients, excessive activity of the muscles around the mouth may contribute to the formation of vertical lines.

Very carefully planned treatment aimed at reducing muscular activity may therefore be considered in certain circumstances.

However, this area requires particular caution because the muscles surrounding the mouth are essential for normal facial expression, speech, eating and drinking. Suitability, expected benefit and potential risks need to be discussed individually.

Why deeper lines may need a different approach

If lines are deeply established, simply adding more filler is not always the answer.

This is particularly important when the problem is predominantly related to skin quality rather than loss of volume. Trying to completely erase every line by adding volume can produce an unnatural result without adequately addressing the underlying problem.

In these circumstances, treatments aimed at improving skin quality or resurfacing may sometimes be more appropriate, either alone or as part of a combined approach.

The important point is that treatment should be based on the underlying anatomy rather than simply on the name of the concern.

Will treatment completely remove smoker’s lines?

My aim with aesthetic treatment is generally to soften and improve rather than promise to completely eliminate every line.

The mouth is constantly moving, and some degree of natural texture and movement is normal. Trying to completely remove every visible line can sometimes require more treatment than is aesthetically appropriate.

Results also vary considerably between patients. Age, skin quality, muscle activity, anatomy, previous treatments and the depth of the lines can all influence the outcome.

For one patient, dermal filler may provide a noticeable improvement. For another, a different treatment or combination of approaches may be more appropriate.

Natural-looking treatment around the mouth

The perioral area is one where subtlety matters particularly to me.

A successful treatment should not leave the mouth looking heavy, overfilled or disconnected from the rest of the face. I prefer to assess the lips, surrounding skin and overall facial proportions together before recommending treatment.

Sometimes that means treating the lines directly. Sometimes improving support elsewhere produces a more balanced result. And occasionally I may recommend against filler if I don't believe it is the right treatment for the problem.

The objective is not to remove every sign of ageing. It is to achieve an improvement that still looks natural when you speak, smile and express yourself.

Smoker’s lines treatment in Warrington

If you are concerned about vertical lip lines or smoker’s lines, the first step is an individual consultation.

At Dr Cotiga Aesthetic Clinic in Warrington, I will assess the area, discuss what is contributing to the lines and explain which options may—or may not—be appropriate for you.

Every face is different, and treatment should reflect that.
