Bunny Lines, Gummy Smiles, and Dimpled Chins: Advanced Tweakment Zones

Many people researching aesthetic treatments are already familiar with the most commonly discussed areas — forehead lines, crow's feet, and lip volume. However, a growing number of patients are now asking about the subtler, more nuanced facial zones that can be equally significant in how the face moves, ages, and is perceived. Areas such as bunny lines on the nose, a gummy smile, or a dimpled chin texture are often described as "finishing touches" in advanced aesthetic practice, yet they can have a meaningful impact on overall facial harmony and self-confidence.
If you have noticed wrinkles appearing across the bridge or sides of your nose when you smile, excessive gum visibility when your lips part, or an uneven, pitted texture on the chin, you are not alone in wondering whether these concerns can be addressed. This article explores these advanced tweakment zones — what they are, how they form, which treatment approaches may be relevant, and what realistic expectations look like for patients considering professional assessment in London.
What Are Advanced Tweakment Zones in Aesthetics?
Advanced tweakment zones refer to specific facial areas — including bunny lines on the nose, gummy smiles caused by upper lip elevation, and dimpled chin texture from mentalis muscle activity — that respond to targeted aesthetic treatments. These areas are distinct from standard treatment zones and typically require careful individual assessment by an experienced qualified practitioner.
What Are Bunny Lines, Gummy Smiles, and Dimpled Chins?
These three concerns are grouped together because they share a common characteristic: they are all influenced by underlying muscle activity and are often overlooked in basic aesthetic treatment planning. Understanding each one individually helps patients approach professional consultations with clearer expectations.
Bunny Lines are the diagonal or horizontal wrinkles that appear on the sides or bridge of the nose when a person smiles, laughs, or scrunches their face. They are caused by the repeated contraction of the nasalis muscle and can become more prominent over time as the skin loses elasticity.
Gummy Smiles refer to the visible appearance of an excessive amount of gum tissue when a person smiles. This is primarily caused by hyperactivity of the levator labii superioris alaeque nasi muscle, which elevates the upper lip higher than average. For some people, this is simply a natural anatomical characteristic; for others, it can be a source of self-consciousness.
Dimpled or Pebbled Chin texture is caused by overactivity of the mentalis muscle — the muscle responsible for chin movement and lower lip depression. When this muscle contracts repeatedly or is in a state of chronic tension, the overlying skin can develop an irregular, cobblestone-like surface texture.
The Science Behind Muscle-Driven Facial Changes
To understand why these concerns develop, it is helpful to consider the relationship between facial muscles, repeated movement, and the skin's structural integrity over time.
The skin is supported by a network of collagen and elastin fibres within the dermis. Collagen provides structural firmness, while elastin allows the skin to recoil after movement. From the mid-twenties onwards, the body's natural collagen production begins to slow, and elastin fibres become less resilient. This means that the dynamic creases created by repeated facial expressions gradually become more visible — even at rest.
In the specific zones discussed in this article, individual muscle anatomy and activity patterns play a particularly important role. The nasalis, levator labii superioris, and mentalis muscles all contribute to natural, expressive facial movement. However, their repeated and sometimes excessive contraction can lead to visible surface changes in the skin above them. Environmental factors — including sun exposure, smoking, and dehydration — can accelerate these changes by further degrading collagen and compromising the skin barrier. Understanding this interplay between intrinsic ageing, muscle dynamics, and lifestyle helps patients appreciate why some concerns appear in these specific areas and not others, particularly when comparing dynamic and static wrinkles.
How Are These Areas Typically Treated?
Advanced tweakment zones are generally approached using muscle-relaxing injections, sometimes referred to as anti-wrinkle treatments, which work by temporarily reducing the activity of the target muscle. In the UK, botulinum toxin is a prescription-only medicine (POM) and should only be prescribed after a face-to-face consultation by an appropriately qualified prescriber. This allows the overlying skin to smooth and soften, often producing a more refined facial appearance.
Bunny Lines are commonly addressed with small, precisely placed muscle-relaxing injections targeting the nasalis muscle. The goal is to soften the visible creases without disrupting natural facial expression or causing asymmetry.
Gummy Smiles can be approached using carefully dosed muscle-relaxing injections into the upper lip elevator muscle. By gently reducing the elevation of the upper lip on smiling, the amount of visible gum tissue can be reduced. This is considered an advanced technique requiring precise anatomical knowledge, as the upper lip area involves multiple overlapping muscle groups.
Dimpled Chin texture is treated by targeting the mentalis muscle. Reducing its activity allows the skin surface above it to relax and smooth. In some cases, where skin laxity or volume loss also contributes to the texture, a qualified practitioner may discuss whether complementary treatments are appropriate following individual assessment.
It is important to understand that treatment approaches are always determined following individual consultation and cannot be generalised. If you are researching anti-wrinkle treatment options, a professional assessment is the appropriate first step.
Who May Benefit From Professional Consultation?
Aesthetic consultations for advanced tweakment zones are appropriate for patients who have noticed specific concerns in these facial areas and would like to understand their options in an informed, unhurried environment.
You may find a professional consultation helpful if you:
Have noticed diagonal lines appearing on the sides of your nose during facial expressions
Feel self-conscious about the amount of gum tissue visible when you smile
Have observed an irregular or pebbled texture on the surface of your chin
Are already receiving treatments for other facial areas and wish to refine overall facial balance
Would like to understand whether the changes you are seeing are related to muscle activity, skin ageing, or both
It is worth noting that not everyone will wish to address these concerns, and there is no requirement to do so. Aesthetic treatment is always a matter of individual choice. A qualified practitioner will assess your anatomy, discuss your personal goals, and explain whether treatment is appropriate — without pressure or expectation. These are subtle, nuanced areas, and results depend significantly on individual facial anatomy, muscle activity patterns, and skin quality.
Realistic Benefits, Limitations, and Expectations
As with any aesthetic treatment, understanding both the potential benefits and the realistic limitations is essential to forming balanced expectations.
Potential Benefits:
Softening of dynamic wrinkles in these specific zones Reduced visibility of gum tissue on smiling (when gummy smile is muscle-driven) Smoother chin surface texture Enhanced overall facial refinement when combined with broader treatment planning Non-surgical approach with no requirement for general anaesthesia or significant recovery time
Limitations to Consider:
Results are temporary and require maintenance treatments to sustain
Individual anatomy significantly influences outcomes — results vary between patients
Advanced zones such as the gummy smile carry a higher technical complexity, meaning practitioner expertise is particularly important
Not all cases are suitable for treatment with muscle-relaxing injections alone; some may involve structural or anatomical factors that are not addressable through this approach
Over-treatment in sensitive areas can affect natural expression and function, which is why conservative, staged treatment is generally preferred
There are no guaranteed outcomes with any aesthetic procedure. A responsible practitioner will always explain the range of possible results, including the possibility that the outcome may not meet expectations, before any treatment proceeds.
Aftercare and Skin Health Considerations
Following treatment in any of these advanced zones, general aftercare principles apply alongside any specific guidance provided by your treating practitioner. Whilst individual aftercare instructions should always take precedence, the following considerations are broadly relevant:
Avoid touching or applying pressure to the treated area for the first few hours following treatment
Refrain from strenuous exercise, saunas, or steam rooms for the remainder of the treatment day
Sun protection is important year-round, but particularly in the post-treatment period — use a broad-spectrum SPF 30 or higher daily
Stay well hydrated — adequate skin hydration supports overall skin health and can complement treatment outcomes
Avoid alcohol on the day of treatment to minimise the risk of bruising
Attend follow-up appointments as recommended by your practitioner, particularly for first-time treatments in advanced zones, where fine-tuning of dosage may be appropriate
Maintain a consistent skincare routine including gentle cleansing, moisturising, and antioxidant protection to support long-term skin health between treatment appointments
Good skin health is a continuous investment. Aesthetic treatments work best alongside, rather than instead of, a considered daily skincare routine and healthy lifestyle habits.
How Long Do Results Typically Last?
Results from muscle-relaxing treatments in these advanced zones are temporary. The duration of effect varies between individuals and is influenced by a number of factors including:
The individual's metabolic rate The dose used (conservative dosing in sensitive areas may have a shorter duration) The degree of muscle activity in the treated area Lifestyle factors such as exercise frequency, sun exposure, and smoking Whether the patient has received previous treatments in the area
As a general guide, muscle-relaxing treatments typically last between two and four months, though this varies. Over time, with regular maintenance treatments, some patients report that results appear to extend slightly as the muscle gradually adapts to reduced activity. However, this is not universal and should not be assumed.
Patients considering skin booster treatments alongside targeted muscle-relaxing treatments may wish to discuss a broader treatment plan during their consultation to support overall skin quality.
Risks and Considerations
All injectable aesthetic treatments carry potential risks. In the context of advanced tweakment zones, it is particularly important to be aware of the following:
Bruising and swelling at the injection site are the most common side effects and are generally temporary
Asymmetry — particularly relevant in the upper lip and gummy smile area, where muscle balance is critical
Unintended muscle effects — in areas with complex overlapping muscle anatomy, such as the upper lip, adjacent muscles can occasionally be affected, temporarily altering smile appearance or lip movement
Under-correction or over-correction — finding the appropriate dose requires clinical judgement and, in some cases, a staged approach with review
Infection — whilst rare with proper technique and sterile products, as with any injection procedure it remains a possibility
These risks underline the importance of seeking treatment from a qualified, experienced aesthetic practitioner. The JCCP recommends that patients verify the credentials and registration of any practitioner before proceeding with any injectable treatment, and patients often find it useful to review Medically Led Aesthetic Clinics: Safety & Outcomes | London | Pantaleo Aesthetic Clinic London. Patients should verify practitioner registration with the GMC or GDC where relevant and check CQC registration status for clinics where applicable.
Who Should Avoid These Treatments?
Certain individuals may not be suitable candidates for muscle-relaxing treatments in these zones. Contraindications and cautions are assessed during a thorough consultation and may include:
Pregnancy or breastfeeding Known allergy or hypersensitivity to any ingredient in the treatment product Certain neuromuscular conditions Active skin infection or inflammation in the treatment area Specific medications that may interact with treatment
This is not an exhaustive list. Individual suitability is always determined through a face-to-face consultation with a qualified practitioner, who will review your medical history in full before recommending any course of treatment.

Key Points to Remember
Bunny lines, gummy smiles, and dimpled chins are advanced tweakment zones influenced primarily by underlying facial muscle activity.
Muscle-relaxing injections are the most common treatment approach for these areas, though suitability must be assessed individually.
Results are temporary and require maintenance; individual outcomes vary significantly.
Advanced zones carry greater technical complexity, making practitioner expertise particularly important.
Realistic expectations are essential — no aesthetic treatment guarantees specific outcomes, and a responsible practitioner will always discuss both benefits and limitations.
Professional consultation is the appropriate starting point for any patient considering treatment in these areas.
Conclusion
Bunny lines, gummy smiles, and dimpled chin texture are increasingly recognised as meaningful concerns within advanced aesthetic practice. Whilst they may be subtler than the more commonly discussed facial areas, they can have a significant impact on how the face is perceived — both during expression and at rest. Understanding that these concerns are primarily driven by specific muscle activity patterns, and that they can be influenced by targeted treatment approaches, empowers patients to have more informed conversations with qualified practitioners.
As with all aesthetic treatments, the decision to explore these options is deeply personal. There is no universal standard for whether or how any of these concerns should be addressed. What matters most is that patients feel informed, unhurried, and fully aware of realistic expectations before making any decisions.
Advanced tweakment zones require an experienced clinical eye, a thorough understanding of facial anatomy, and a conservative treatment philosophy. The subtlety of the areas involved means that small differences in technique and dosage can have a meaningful impact on outcome.
Treatment suitability, risks, and expected outcomes should always be assessed individually during a professional consultation.
Frequently asked questions
Are bunny lines a sign of ageing or are they caused by something else?+
Bunny lines are caused by the repeated contraction of the nasalis muscle during facial expressions such as smiling or scrunching the nose. Whilst they can become more noticeable with age as skin elasticity and collagen levels decline, they can also appear in younger individuals with strong nasalis muscle activity. They are not exclusively an ageing concern, but they tend to become more persistent at rest as the skin loses its ability to fully recoil from repeated movement over time.
Is treating a gummy smile safe, and what are the main risks?+
When performed by a qualified and experienced practitioner, treatment for a gummy smile using muscle-relaxing injections is considered a safe and well-established approach. The main risks include temporary asymmetry, unintended effects on adjacent lip muscles, and variation in how much the upper lip elevation is reduced. Because the upper lip area involves multiple overlapping muscles, precise placement and appropriate dosing are critical. Results are temporary, and any asymmetry or unexpected effects will typically resolve as the treatment wears off.
How is a dimpled chin treated, and will it look natural?+
A dimpled or pebbled chin caused by overactive mentalis muscle activity is typically addressed using small, carefully placed muscle-relaxing injections. The aim is to reduce muscle contraction sufficiently to allow the overlying skin to smooth, without eliminating the natural movement of the chin and lower lip. When performed conservatively and by an experienced practitioner, the outcome can appear very natural. As with all treatments in this zone, individual anatomy will influence results, and outcomes cannot be guaranteed.
How many treatment sessions are typically needed?+
For most patients, a single treatment session is performed initially, followed by a review appointment after two to three weeks to assess the outcome and determine whether any refinement is needed. Over time, patients who maintain regular treatments typically develop a clearer understanding of their personal response to dosing, which supports more predictable outcomes. There is no fixed number of sessions that applies to all patients — treatment frequency and longevity are individual.
Can these areas be treated at the same time as other facial zones?+
In many cases, yes. It is common for practitioners to address multiple zones within the same appointment, particularly when a patient is seeking overall facial refinement rather than isolated improvement in one area. However, the order, combination, and timing of treatments in different zones will be determined by the treating practitioner based on individual assessment. Treatment planning should always be led by clinical judgement rather than patient-directed combinations, to ensure safety and appropriate outcomes.
What should I look for when choosing a practitioner for advanced zone treatments?+
For advanced tweakment zones, practitioner expertise is particularly important given the complexity of the anatomy involved. Patients are advised to seek a practitioner who is a registered healthcare professional with specific training and demonstrated experience in facial aesthetics. It is reasonable to ask about qualifications, professional registration, clinical experience in the specific treatment area, and the clinic's approach to complications management. The JCCP provides guidance on practitioner standards and patient safety in the UK aesthetic sector.
