Botox for Lip Lines: Everything You Need To Know

As we age, our lips lose some of their youthful fullness and we develop lines around the mouth. These lip lines can be caused by a variety of factors, including the natural aging process, sun damage and smoking. Vertical lines above the upper lip, often referred to as smoker’s lines, and fine lines around the border of the lips, known as lipstick lines, can become especially noticeable. 

Fortunately, there are solutions available to address lip lines and restore a smoother, more youthful appearance. Botox, a purified protein derived from the botulinum toxin, is a popular option that can effectively reduce the appearance of these lines. By relaxing the muscles that contribute to puckering and other facial expressions, Botox can soften lip lines and even create a subtle plumping effect. Here’s how!

Types and Causes of Lip Lines

Lip lines come in various forms, each with its own cause. Here’s a breakdown of the most common types:

  • Smoker’s Lines: These vertical lines that run from the corners of the mouth down towards the chin are often associated with smoking, but not exclusively. Repetitive facial expressions, like pursing your lips, can also contribute to their formation.
  • Vertical Lip Lines: These fine lines appear just above the upper lip and become more pronounced with age and sun damage. The weakening of the orbicularis oris muscle, responsible for lip movement, plays a role in their development.
  • Lipstick Lines: These fine lines form around the vermilion border, the edge where your lips meet the skin. As we age, collagen and hyaluronic acid production decline, leading to a loss of volume and the appearance of these lines.

How Botox Treats Lip Lines

Lip lines often form due to repetitive muscle contractions. When we pucker our lips, smile, or frown, the orbicularis oris muscle, which surrounds the mouth, contracts and pulls the skin inward. Over time, these repeated contractions can lead to the formation of vertical lines above the upper lip and lipstick lines around the border of the lips.

To treat them, Botox injections are strategically placed around the upper lip, particularly near the cupid’s bow and corners of the mouth. By blocking the release of a neurotransmitter that triggers muscle contraction, the botulinum toxin weakens the grip of the orbicularis oris muscle. This relaxation allows the upper lip to evert slightly outward, softening the appearance of vertical lines and creating a subtle plumping effect.

Botox vs. Dermal Fillers: Which is the Best Treatment for Lip Lines?

Botox and dermal fillers are both injectable cosmetic treatments used to address lip lines, but they work in different ways. While Botox relaxes muscles to smooth out the upper lip area, fillers add volume and definition.

These injectable gels are composed of hyaluronic acid and include brands like Juvederm Volbella and Restylane Kysse. When injected into lip lines, fillers plump up the tissue, smoothing out lipstick lines and restoring lost volume. Lip filler treatments can also be used to enhance the shape of the lips or address a gummy smile (excessive gum exposure when smiling).

Choosing the Right Option

  • Botox: The best choice for addressing lines caused by muscle movement, particularly vertical lip lines. It offers a natural-looking result and minimal downtime. However, it doesn’t add volume.
  • Dermal Fillers: Ideal for restoring lost volume, addressing lipstick lines or enhancing the shape of the upper and lower lips. They offer longer-lasting results and the potential for more dramatic lip enhancement than Botox but require more expertise for natural-looking outcomes.

How Many Units of Botox Do I Need for Lip Lines?

The number of Botox units needed for lip lines depends on several factors, including:

  • Severity of lines: Deeper lines may require more units for optimal results.
  • Desired outcome: A subtle lip flip might require fewer units than a more dramatic effect.
  • Individual muscle strength: Some people have naturally stronger muscles, requiring slightly more units.

With all these factors in mind, most people require between 2–6 units for lip lines.

Side Effects of Botox for Lip Lines

Botox and other FDA-approved neurotoxin brands such as Dysport and Xeomin are considered safe and effective, but like any medical procedure, it can cause some temporary side effects. Here’s what to expect:

  • Mild bruising or swelling: These typically resolve within a few days and can be minimized with proper ice pack application.
  • Temporary tenderness or numbness: You might experience some slight tenderness or numbness around the injection sites, which usually fades within a day or two.
  • Uneven results: In rare cases, the Botox may not be distributed perfectly, leading to temporary asymmetry. This can be easily corrected with a small touch-up injection.

More serious side effects, like difficulty speaking or swallowing, are extremely rare but can occur if the Botox migrates beyond the intended injection sites. If you experience any concerning symptoms after your treatment, contact your injector immediately.

Alternative Treatments for Lip Lines 

Botox is a fantastic option for addressing lines caused by muscle movement, but it’s not the only weapon in the arsenal against lip lines. Here are some other treatments you might consider, either alone or in combination with Botox:

  • Microneedling: This minimally invasive procedure involves creating tiny controlled punctures in the lip area. This stimulates collagen production, leading to a gradual improvement in lip texture and a reduction in the appearance of fine lines.
  • Chemical Peels: A gentle chemical peel can help remove dead skin cells and stimulate collagen production around the lips, improving overall tone and texture and potentially lessening the appearance of fine lines.
  • Laser Resurfacing: In some cases, more advanced laser treatments can be used to address deeper wrinkles and sun damage around the lips. However, these procedures require more downtime and are a bigger investment compared to other options.

Botox Lip FLip vs. Botox for Lip Lines: What’s the Difference?

Botox for lip lines address a broader range of lines around the mouth, including vertical lines above the upper lip and lipstick lines. It works by relaxing the muscles responsible for puckering and other facial expressions, leading to a general softening of these lines. 

The Botox lip flip, on the other hand, is a more targeted technique specifically designed to address vertical lines above the upper lip. By strategically injecting Botox near the cupid’s bow and corners of the mouth, it relaxes the muscle that pulls the lip inward, causing a subtle eversion that softens lines and creates a subtle pout. 

So, if your primary concern is vertical lines above the upper lip, the lip flip might be the most suitable option. For a more comprehensive approach to addressing various lip lines, traditional Botox injections could be a better choice.

Important Considerations Before Treatment 

Before getting a cosmetic procedure, a thorough consultation with your board-certified plastic surgeon is crucial. During this consultation, it’s important to openly discuss your desired results and expectations. Be sure to share your medical history, including any medications you’re taking, as certain medications can interact with Botox or other injectable treatments.

The surgeon will also assess your candidacy for treatment. Smoking can actually worsen lip lines and may affect the longevity of Botox injections. Certain medications, like blood thinners, may also increase the risk of bruising after treatment.

Sun exposure is a major contributor to lip lines and overall facial aging. Sun protection is essential for maintaining optimal lip health. Regular use of sunscreen with SPF 30 or higher will help prevent future sun damage and keep your lips looking youthful.


Botox offers a safe and effective way to address lip lines caused by muscle movement, creating a smoother and subtly fuller appearance. To explore if Botox is the right choice for you and discuss a personalized treatment plan, schedule a consultation with a board-certified plastic surgeon like Dr. Thomas McFadden at Advanced Cosmetic Surgery in Greenville, SC today.
