Anti-wrinkle Treatment Areas: A Clinical Guide

The forehead

The forehead is one of the most commonly treated areas with anti-wrinkle injections. Horizontal forehead lines are produced by the frontalis muscle, the large muscle that elevates the brow and is responsible for the surprised or raised brow expression.

The challenge with forehead treatment is that the frontalis is also the primary elevator of the brow. Reducing its activity too significantly can cause brow descent, the brow drops, creating a heavy upper lid appearance that most patients find more bothersome than the original lines.

Appropriate forehead treatment requires careful dose calibration that achieves meaningful line reduction while preserving enough frontalis activity to maintain brow position. This calibration is informed by the individual’s brow position at rest, the degree of natural brow ptosis present, and the relationship between the forehead and the brow elevators.

Most practitioners treat the forehead in conjunction with the frown area, treating both together allows the dose balance between brow elevation and brow depression to be managed holistically.

The frown area (glabella)

The frown area, the vertical creases between the brows, is produced by the glabellar muscle complex, which draws the brows downward and inward in expressions of concentration or displeasure.

This is typically the highest priority area for patients seeking to address expression lines. The glabellar muscles are powerful and the lines they produce are often prominent, both during expression and, over time, at rest.

Treatment of the frown area involves placing anti-wrinkle product at several points along the glabellar complex, targeting the muscles responsible for the downward and inward brow movement. Dosing is calibrated to the individual’s muscle mass and the desired degree of movement reduction.

The frown is also the area most associated with a permanently concerned or stern appearance when lines are deep and persistent. Consistent treatment over time typically produces gradual improvement in static frown lines as the skin is given extended periods without repeated mechanical reinforcement.

Crow’s feet

Crow’s feet, the lines that radiate laterally from the outer corners of the eyes, are produced by the orbicularis oculi muscle, which encircles the eye and is active in squinting, smiling, and many other expressions.

Treatment of crow’s feet involves placing anti-wrinkle product at points lateral to the orbital rim, targeting the lateral fibres of the orbicularis oculi. The approach must avoid the muscle fibres closer to the eye that are responsible for normal blinking and eye closure.

Crow’s feet respond well to anti-wrinkle treatment in many patients. Results are often visible and meaningful, particularly for lines that are primarily dynamic (present during expression). Static crow’s feet that are present at rest may improve more gradually over several treatment cycles.

The tear trough area below the lateral eye requires separate assessment if periorbital hollowing is also a concern, crow’s feet treatment with anti-wrinkle injections addresses the lateral lines but not the periorbital hollow itself.

The brow and periorbital area

The brow shape and position can be subtly influenced by anti-wrinkle treatment through careful manipulation of the balance between the muscles that elevate and depress the brow.

The depressor muscles, particularly the orbicularis oculi in the lateral brow, can be treated to allow the frontalis to exert relatively more upward pull on the lateral brow, producing a subtle lifting effect at the lateral tail of the brow.

This is sometimes described as a nonsurgical brow lift, though the effect is modest and varies significantly between individuals. It is most appropriate for patients with slight lateral brow heaviness and is not a substitute for a surgical approach where significant brow ptosis is present.

The assessment at consultation determines whether brow positioning treatment is relevant and appropriate for the individual’s anatomy and goals.

The upper lip (lip flip)

The lip flip is an anti-wrinkle treatment that targets the orbicularis oris muscle at the upper lip border. By reducing the activity of the muscle fibres that roll the upper lip inward, a small amount of additional upper lip is revealed, the lip appears slightly more everted.

This is not the same as adding volume. The lip flip does not increase the size of the lip, it changes the resting posture of the upper lip border, making slightly more of the lip visible above the vermilion border.

The lip flip is most appropriate for patients with a naturally thin upper lip who are not seeking volume augmentation, and for patients where the upper lip disappears during smiling. It produces a subtle change and is not a substitute for dermal filler where volume is the primary goal.

A small dose is used in this area. The effect typically lasts two to three months, shorter than forehead or frown treatment due to the high movement demands on the lip muscles.

Masseter (jaw muscle)

The masseter is the chewing muscle at the angle of the jaw. Anti-wrinkle treatment in the masseter is used for two main purposes: to reduce jaw muscle bulk that is contributing to a widened lower face appearance, and to reduce discomfort associated with bruxism (teeth grinding).

In patients with significantly enlarged masseter muscles, either constitutional or from habitual grinding, injections into the masseter body reduce the muscle’s bulk over several months. The lower face appears slimmer and the jaw angle becomes less prominent. This effect develops gradually over six to eight weeks and may require a top up dose at the review appointment.

The duration of masseter treatment is typically four to six months before maintenance is required, though with consistent treatment over multiple cycles some patients find the interval extends.

Masseter treatment also reduces the force of grinding and clenching, which can provide meaningful symptomatic relief for patients with bruxism related jaw discomfort or dental wear. This is a functional benefit that is clinically relevant beyond the cosmetic effect.

Neck bands (platysmal bands)

The platysma is a broad, flat muscle that runs from the chest up through the neck to the lower face. With age and repeated contraction, vertical bands of platysmal muscle can become visible along the front of the neck.

Anti-wrinkle treatment of the platysmal bands reduces the prominence of these bands, softening the vertical cords that develop along the anterior neck. This is sometimes described as the Nefertiti lift when combined with treatment of the lower face and jawline.

Treatment of the neck bands requires care due to the proximity of swallowing muscles. Dosing must be conservative to avoid affecting neck function. This is an area where practitioner experience and a thorough anatomical understanding are particularly important.

The consultation at Core Aesthetics assesses whether neck band treatment is appropriate and what the realistic expectations are for the individual’s presentation.

Hyperhidrosis (excessive sweating)

Anti-wrinkle injections are used to treat hyperhidrosis, excessive localised sweating, in the underarms, palms, and feet. The mechanism is the same as cosmetic use: the product reduces the activity of the nerve endings that control sweat gland secretion in the treated area.

Underarm hyperhidrosis treatment is the most commonly performed. Product is placed at multiple points across the underarm in a grid pattern. The effect typically begins within one to two weeks and lasts four to twelve months depending on the individual.

This is a medical treatment for a clinically significant condition, and the consultation approach for hyperhidrosis treatment reflects this, establishing the degree of impairment, previous treatment history, and any relevant medical context before recommending injectable treatment.

How treatment areas are selected at consultation

At Core Aesthetics, the treatment areas addressed in any given appointment are determined by the consultation assessment, not by a pre set menu. Not every patient requires treatment in all commonly available areas.

The assessment identifies which areas are contributing most significantly to the patient’s concerns, what the realistic treatment goals are for each area, and whether addressing multiple areas at the same appointment is appropriate or whether a staged approach would produce better results.

Some patients benefit most from treating the frown and crow’s feet as a priority, with forehead treatment deferred to a subsequent appointment once the brow position impact of frown treatment has been assessed. Others present with a single primary concern that is well addressed by a focused approach.

The consultation also establishes the appropriate dose for each area, which is informed by the individual’s muscle mass, the degree of movement reduction that is appropriate for their goals, and any previous treatment history.

What to expect from Anti-wrinkle treatment

Anti-wrinkle injections take effect gradually over one to two weeks, with full effect visible at approximately two weeks. This is why the review appointment is scheduled at two to three weeks, to assess the settled result and determine whether any adjustment is needed.

The procedure itself is brief, most upper face treatments take ten to twenty minutes. Discomfort is minimal: a brief sharp sensation at each injection point that resolves immediately. No significant downtime is required, though minor bruising at injection sites is possible.

Results typically last three to five months, with variation between individuals. Consistent treatment over time produces cumulative improvement in static lines as skin is given extended periods without repeated mechanical stress from the treated muscles.

A treatment plan is developed over the first two to three cycles and refined based on the individual’s response at each review appointment.

How Many Areas Can Be Treated in One Visit

A question that comes up often during consultations is whether multiple treatment areas can be addressed in one appointment. The short answer is yes, it is common to address two or three areas in a single visit, particularly forehead lines, frown lines, and crow’s feet, which are often treated together as a coordinated upper face approach. When these three areas are treated simultaneously, the result tends to feel more balanced and natural than treating one area in isolation.

That said, there are practical limits. Treating too many distinct areas at once can make it harder to assess outcomes at review, since it becomes difficult to know which change is attributable to which treatment. A staged approach, starting with one or two areas and adding others once you understand how you respond, is often the most informative path.

At Core Aesthetics, the number of areas addressed in a single appointment is always a clinical decision made at consultation, not a package. Some clients benefit from a focused single area treatment; others present with concerns across several areas that are better addressed together. The consultation is where this is worked out, with your anatomy, your goals, and your treatment history all taken into account before any treatment decisions are made.

What Affects How Long Results Last in Each Area

Duration of results varies not just from person to person but from area to area. Forehead and brow results typically last somewhere between three and five months for most people, with high movement areas like crow’s feet sometimes fading faster in people who smile expressively. Masseter results tend to be among the longer lasting, with some clients reporting six months or more before noticeable return of function, though gradual reduction over repeated treatments can extend intervals further.

Several factors influence duration: the dose used, the individual’s metabolism, how much the treated muscle is habitually used, sun exposure, physical activity levels, and whether it is a first treatment or a follow on after prior volume. Over time, repeated treatment of the same area can produce a cumulative effect, muscles that have been regularly relaxed may take longer to return to full activity, meaning treatment intervals can often extend as a treatment relationship develops.

This is not a absolute claim of any particular outcome. Individual responses vary considerably, and it is not possible to predict precisely how long any individual’s results will last in any specific area. Review appointments are part of the treatment process precisely because this variation is real. The review is not a formality, it is where the practitioner and client assess together whether the dose and area selection were appropriate, and whether any adjustment is warranted before the next treatment cycle.

Understanding How Anti-wrinkle Treatment Works at a Cellular Level

Anti-wrinkle treatment uses a prescription injectable that temporarily interrupts the signal between the nerve and the muscle. The active substance blocks the release of acetylcholine at the neuromuscular junction, the chemical messenger that triggers muscle contraction. Without this signal, the targeted muscle relaxes. The skin above it, no longer creased by repeated movement, gradually softens.

This effect is temporary because the body regenerates the nerve terminals that were blocked. Axonal sprouting, the regrowth of nerve endings, is the mechanism by which muscle activity slowly returns, typically over three to five months. The pace of recovery varies between individuals and between treatment areas.

Understanding this mechanism matters for treatment planning. Anti-wrinkle treatment works on muscles. It does not replace volume, improve skin texture, or address structural concerns. For lines that are visible at rest, not just during expression, a different assessment is needed, and filler or other approaches may be more appropriate.

The Role of Facial Mapping in Anti-wrinkle Treatment

Effective anti-wrinkle treatment begins with a detailed understanding of how a specific person’s face moves. The same treatment applied to two different people can produce very different outcomes because the underlying anatomy, muscle size, attachment points, the relationship between muscles, varies considerably from person to person.

At Core Aesthetics, the pretreatment assessment includes observing movement patterns, identifying which muscles are contributing to the lines of concern, and understanding how treatment in one area might influence adjacent muscles. For example, treating the forehead without accounting for the brow position can produce a result that looks heavy or drops the brow unexpectedly. Treatment planning that ignores these relationships is a common source of dissatisfaction.

Facial mapping is not a visual tool, it is a clinical one. The goal is to understand function, not just appearance. A treatment plan designed around function is more likely to produce a result that looks natural and balanced, because it works with how the face moves rather than simply suppressing whatever is visible.

Clinical accountability and how this preparation guide is reviewed

The pretreatment guidance in “Anti-wrinkle Treatment Areas: Why Movement Comes Before Areas” reflects how Corey Anderson, AHPRA registered nurse (NMW0001047575), prepares patients during the consultation phase at Core Aesthetics. Preparation matters more than most patients realise. Many of the variables that shape the day of treatment experience, bleeding tendency, hydration, skin condition, medication interactions, are decided in the days before the appointment, not on the chair. Results vary between individuals, but preparation reduces the variability that’s within a patient’s control. The recommendations on this page are framed around what an AHPRA-regulated practitioner can and cannot tell a patient to do, and what the published evidence supports for cosmetic injectable preparation.

Specific to guide: the timing windows on this page are typical, not absolute. Some patients metabolise medications, alcohol, or supplements faster or slower than the average, body composition, age, liver function, and concurrent prescriptions all matter. Patients on prescription anticoagulants must not stop them before cosmetic treatment without checking with their prescribing doctor first; the bleeding risk from cosmetic injectables is far smaller than the clotting risk from stopping anticoagulation unsupervised. The Anti-wrinkle treatment Melbourne page covers adjacent considerations in more detail.

The Core Aesthetics clinic operates from 12A Atherton Road, Oakleigh VIC 3166, Tuesday to Saturday, by consultation appointment. All new patient treatment at Core Aesthetics follows a structured clinical consultation, consistent with the September 2025 AHPRA cosmetic procedures guidelines. Treatment may be scheduled for the same day as consultation or at a subsequent appointment, depending on clinical assessment and individual circumstances. Patients with questions about the content on this page can raise them at consultation; the practitioner is happy to walk through any clinical reasoning that the written content does not fully capture. Results vary between individuals, and the consultation is the appropriate place to discuss what those individual variations mean for a specific person’s treatment plan.
