Lip lines are one of those concerns that sound simple until you start researching them. Some people mean the vertical lines above the top lip (often called smoker’s lines, even in non-smokers). Others use “lip lines” to describe lines around the mouth more broadly. Add in factors like facial movement, collagen loss, sun exposure, dehydration, and smoking, and it can be hard to work out what is actually being treated and with which approach. 

That detail matters because Botox is a prescription-only medicine, and the area around the mouth is functional as well as cosmetic. Small changes in muscle activity can affect day-to-day movements, so it’s important to understand the trade-offs and realistic limits before you compare clinics or prices. This is also why practitioner selection is not a box-ticking exercise; you want someone who is medically qualified to assess your anatomy, explain alternatives, and manage complications if they occur. 

In this guide, you’ll learn what causes lip lines, how Botox is used to relax the muscles around the lips, what a typical appointment involves, and how long results may take to appear and last. We’ll also cover cost context, potential side effects (including temporary changes in lip function), and what “safe hands” looks like in the UK, including relevant professional regulators.

How Are Lip Lines Caused?

A number of factors can lead to lip lines.

Alongside general ageing and a loss of collagen and elastin, excessive sun exposure, smoking, and dehydration are all key contributors.

Women tend to be affected more than men due to a thinner dermal layer and less hair in the upper lip area.

Can You Get Rid of Lip Lines With Botox?

Lip lines can be successfully treated with Botox and other brands of botulinum toxin; an injectable product that has the power to smooth wrinkles.

Botox is an anti-wrinkle injection that will help to relax the muscle that surrounds the lips (orbicularis oris) and prevent excessive creasing when pursuing your lips.

When Should You Start Botox Injections for Lip Lines?

Age is not a factor for lip lines. While most patients are between the ages of 35 and 60, they can affect anyone. If your lines are fine at the moment, treatment could help them get worse.

On the other hand, if you have deep lip lines, then you may also benefit from dermal filler or laser therapy.

Under-18s are not allowed to undergo treatment for lip lines in the UK.

What Should I Expect From Botox for Smile Lines Treatment?

A topical anaesthetic is usually applied prior to this treatment and Botulinum toxin injections are strategically placed to reduce the appearance of the lines around your top lip.

Treatment is quick; usually less than 30 minutes, and doesn't hurt; you will simply feel a 'sharp scratch' when the needle goes in.

There may be some redness and swelling, which will calm down a few hours after treatment.

Results will take two weeks to become fully apparent and should last between three to six months.

How Much Does It Cost to Treat Lip Lines With Botox?

On average, Botox for smile lines treatment can cost anywhere from £200 upwards. The price usually depends on where in the country you're having treatment and how experienced your practitioner is.

Be safe when choosing a practitioner – it's worth paying a bit more to see someone with experience!

Are There Side Effects to Treating Lip Lines With Botox?

Side effects to Botox and other brands of botulinum toxin are rare, but can include:

  • Degree of lip incompetency (difficulty blowing balloons and sucking on a straw)

  • Slight numbness in the upper lip

  • Swelling

  • Allergic reaction

The most dangerous complications are double vision and difficulty breathing, but these are thankfully extremely rare.

If you experience any side effects or complications, contact your practitioner immediately.

Who Should You Trust to Treat Your Lip Lines?

Always look for a medical practitioner who can advise you on the best treatment approach. Sometimes dermal fillers or laser therapy may be more appropriate, depending on the severity of your lip lines.

We highly recommend that you only undergo Botox for smile lines treatment with a medically-qualified professional, who will have undergone training in anatomy and physiology, as well as be accountable to a regulatory body such as the General Medical Council (GMC), Nursing and Midwifery Council (NMC) or General Dental Council (GDC).

They should also be able to advise you of the risks of injectable treatment for smile lines, what the procedure involves and be confident in handling complications if they arise.
