Wrinkle treatment at Core Aesthetics uses a prescription injectable to temporarily reduce the activity of specific facial muscles that cause expression lines. At Core Aesthetics, clinical decisions follow a consultation-first approach and conservative treatment philosophy.
One of the most practical questions clients have about wrinkle injectable treatment is how often they will need to repeat it. The answer is more individual than the “every three to four months” figure commonly cited suggests, and understanding the factors involved helps you plan realistically.
This article covers maintenance intervals from the clinical perspective of Corey Anderson, AHPRA registered nurse, at Core Aesthetics in Oakleigh.
“Good information changes the quality of the decision.”
Why Wrinkle Treatment Is Not Permanent
Wrinkle injectable treatment uses a prescription product that temporarily reduces the activity of targeted facial muscles by interrupting nerve signalling at the muscle junction. The mechanism is temporary because the nerve terminals regenerate over time, gradually restoring communication with the muscle. As nerve signalling returns, muscle activity increases and the treatment effect fades. This is a predictable biological process rather than a product limitation.
What This Means in Practice
The rate at which this regeneration occurs varies between individuals. It is influenced by your individual metabolism, physical activity level, the dose used at your treatment and the specific muscle and treatment area involved. More active muscles in areas of frequent movement, like the crows feet area around highly expressive eyes, may show shorter duration than less frequently engaged muscles. Your practitioner will discuss realistic duration estimates for your specific treatment areas at your consultation.
Typical Duration and What Affects It
Most clients find that wrinkle treatment results last in the range of three to five months, though this is a guide rather than a fixed timeline. Clients with a faster metabolism or higher physical activity levels sometimes find results fade sooner. Clients with lower muscle activity or who have been having consistent treatment over a longer period sometimes find slightly longer duration. The treatment area matters too, with jaw muscle treatment for jaw width and grinding typically lasting longer than upper face expression areas due to the lower movement demands on that muscle between treatment appointments.
What This Means in Practice
The dose used at your treatment is also relevant. A lighter conservative dose in a particular area will fade sooner than a more assertive dose. For clients beginning treatment for the first time with a conservative first dose, this means the initial result may not last as long as subsequent treatments where the appropriate dose for your individual muscle activity has been better established.
How to Think About Maintenance Intervals
The most practical approach to maintenance is to book your next appointment when you notice your treatment starting to fade rather than at a fixed calendar interval. For most clients this is somewhere in the three to five month range. Booking too early, before results have faded, means treating muscle activity that is not yet fully returned. Booking too long after results have faded means any preventative benefit from the treatment is paused during the gap.
For clients with a preventative focus, consistent treatment intervals that avoid long gaps are generally more effective than sporadic treatment. This is discussed in more detail in our overview of preventative aesthetics in Melbourne.
Reducing Frequency Over Time
Some clients find that with consistent treatment over a longer period, slightly lighter doses can maintain a similar result as the muscle adapts to sustained reduced activity. This is not a universal pattern, and it is not something to plan a treatment schedule around. But for clients who have been having regular treatment for several years, a conversation with your practitioner about whether the dose and interval can be reviewed is reasonable.
Consistent sun protection is also worth noting here. As discussed in our article on SPF as a foundation of preventative aesthetics, protecting skin quality through daily sun protection reduces the ongoing UV driven changes that wrinkle treatment is partly addressing. This does not reduce the need for treatment but supports the overall outcome of the treatment plan.
What Your Practitioner Advises
At Core Aesthetics, the appropriate maintenance interval for your individual treatment is discussed at your appointment based on your specific treatment areas, the dose used and your previous treatment history. There is no fixed protocol applied to all clients. For clients new to wrinkle treatment, a review appointment at two weeks after the initial treatment is standard to assess the full result and discuss what a realistic maintenance plan looks like for your situation. See our article on wrinkle treatment aftercare for what to expect in the period following treatment.

General Information Only. This article is general in nature and does not replace a consultation with a qualified health practitioner. Treatment outcomes, suitability and risks vary by individual. Any medical or prescription treatment options can only be discussed and provided where clinically appropriate following an individual assessment.
Safety, Suitability and Clinical Assessment
All aesthetic treatment procedures carry risk. The suitability assessment at consultation identifies any contraindications or relative risk factors specific to your circumstances, including medical history, current medications, previous procedures, and anatomical features that may affect the risk profile for a given treatment area. This information is reviewed before any treatment is planned.
For certain conditions and medications, injectable treatments are not appropriate, or require modification of technique or timing. For others, the treating practitioner may recommend that you consult with your primary healthcare provider before proceeding. These are clinical judgements that can only be made with accurate, complete medical history information, which is why the consultation history taking process is thorough.
Complication recognition and initial management are part of the clinical competency required of practitioners performing injectable treatments under AHPRA’s September 2025 guidelines for nonsurgical cosmetic procedures. The practitioner at Core Aesthetics holds current training in this area and maintains the relevant management supplies on site. Understanding that risk exists and is actively managed is more useful than assuming risk does not exist.
Review Appointments and Ongoing Care
A review appointment at four to six weeks is a standard part of every treatment cycle at Core Aesthetics. The review is not contingent on whether you have concerns, it is a clinical standard that applies to every patient. At review, the practitioner assesses the result across all treated areas, compares the outcome to the pretreatment clinical photographs, identifies any asymmetry or variation in response between sides, and determines whether any adjustment is appropriate within the same treatment cycle.
The review is also where longitudinal data about how your specific anatomy responds to treatment is recorded. Over multiple treatment cycles, this accumulated data allows the practitioner to refine the dosing and approach to better match your individual response pattern, which is one of the most significant advantages of maintaining a consistent treating practitioner rather than moving between clinics.
If you have any concerns in the period between your treatment and your review appointment, contact the clinic directly. The practitioner who treated you has the clinical context to respond accurately to any post treatment question, which is preferable to relying on general online information that may not reflect your specific situation.
What the Assessment Covers
The assessment at the consultation appointment is a face wide evaluation, not a focused review of only the area you have identified as a concern. This full face approach is deliberate: anatomical features interact with each other, and addressing one area in isolation, without understanding the broader facial context, can produce results that look disproportionate even when the individual area was technically treated well.
The practitioner evaluates facial symmetry, bone structure, soft tissue distribution, skin quality, and the dynamic movement patterns associated with each treatment area. The history taking covers your current medications, any previous injectable or surgical procedures, relevant health conditions, and any prior reactions or complications. From this assessment, the practitioner develops a treatment plan that reflects your specific anatomy and circumstances.
Results vary between individuals. What the assessment finds in one patient may be different from what it finds in another patient with a similar presenting concern, which is why templated treatment protocols are not used here. All treatments at Core Aesthetics are consultation based and individually assessed.
Understanding How Wrinkle Treatment Works at a Cellular Level
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. 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 volume treatment or other approaches may be more appropriate.
The Role of Facial Mapping in Wrinkle Treatment
Effective 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.
What Results Can Realistically Be Expected
Wrinkle treatment is effective at softening dynamic lines, lines that appear during expression. For most people, consistent treatment over time produces a visible reduction in the depth of these lines even at rest, as the skin is given repeated periods of reduced mechanical stress.
However, there are realistic limits. Lines that have been present for many years and are deeply etched into the skin may not fully resolve with wrinkle treatment alone. Very deep static lines, visible without any movement, often require additional approaches, which are discussed at consultation. wrinkle treatment cannot restore lost volume, improve skin quality, or address structural changes associated with ageing.
Results vary between individuals. Factors that influence outcomes include muscle mass and activity, metabolic rate, skin quality, and the specific area treated. At Core Aesthetics, results are reviewed at a follow up appointment at four to six weeks to assess the outcome and determine whether any adjustment is appropriate.
Safety, Complications, and Clinical Oversight
Wrinkle treatments are among the most extensively studied injectable treatments in cosmetic medicine. Serious adverse events are rare when treatment is performed by a trained, registered practitioner working within a clinical framework. The most common side effects are minor and temporary: bruising, redness, or tenderness at injection sites.
More significant complications, such as ptosis (drooping of the eyelid or brow), asymmetry, or an overcorrected result, do occur and are related to dose, placement, and individual anatomy. These risks are explained at consultation, documented in the consent process, and managed at the follow up appointment if they arise. At Core Aesthetics, Corey provides emergency contact protocols and clear instructions for who to contact if a concern develops between appointments.
Certain health conditions and medications affect suitability for wrinkle treatment. A full medical history review is part of every consultation. Treatment is not offered where there is clinical uncertainty about safety, and patients are referred to their treating doctor when appropriate.
Clinical accountability and how Wrinkle dosing is decided
The wrinkle treatment guidance in “How Often Do You Really Need wrinkle Treatment?” is informed by how Corey Anderson, AHPRA registered nurse (NMW0001047575), approaches neuromodulator dosing at Core Aesthetics: low to moderate units, conservative on first time treatments, and reviewed at two weeks before any top up. wrinkle treatment is a neuromuscular intervention, and the same units can read very differently on two patients depending on muscle mass, baseline expression patterns, metabolism, and prior treatment history. Results vary between individuals, which is why the two week review appointment exists and why dosing decisions evolve across the first three or four treatments rather than being set once.
Specific to how often wrinkle treatment: wrinkle dosing decisions at Core Aesthetics start conservatively, low to moderate units for first time patients, with a two week review built into the protocol so any top up is informed by how the patient actually responded rather than by a generic dosing chart. Some patients are highly sensitive responders and need less than the typical starting dose; some are slower responders and benefit from a top up at the two week mark. The body of literature on neuromodulator dosing supports the two week review as a clinical reference point, not a marketing concept. The wrinkle treatment Melbourne page covers a related wrinkle decision in more depth.
Patients reading this page who want to verify Corey Anderson’s AHPRA registration can do so directly on the AHPRA public register at ahpra.gov.au using registration number NMW0001047575. 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.
One additional consideration for wrinkle treatment: dosing decisions evolve across treatments rather than being fixed by a chart. The two week review appointment after the first treatment captures how the patient actually responded, not how the average patient responds, and informs dosing choices for the next treatment. Patients who have been on a stable dose for years sometimes find that the dose can be reduced over time as muscle activity reduces with consistent treatment; this is a normal evolution, not an indication that the treatment has stopped working. Patients researching the topic in more depth may find the patient safety aesthetic treatments page and the consultation guide Melbourne page useful as further reading; both are written and reviewed under the same clinical accountability framework as this page.

Frequently asked questions
How often should I have wrinkle treatment?
This depends on how long results last for you individually. Most clients return every three to four months. Some return every five to six months after years of consistent treatment.
What happens if I space treatment too far apart?
If you wait until movement has fully returned before repeating treatment, lines will temporarily reappear. These typically become less etched with ongoing treatment than if you’d never had treatment.
Is frequent wrinkle treatment harmful?
No. Years of consistent, appropriately dosed treatment is safe. Your body doesn’t ‘resist’ the treatment with repeated use.
Can I take breaks from wrinkle treatment?
Yes. Your muscles return to normal activity over three to four months. You can resume treatment whenever you want.
How will I know when to return for treatment?
You’ll notice your movement returning and lines beginning to reappear. Most clients return when this becomes noticeable to them.
Do results improve if I have treatment more frequently?
Not meaningfully. Treatment at your normal interval produces the intended result. More frequent treatment doesn’t produce better outcomes.
What if I want to reduce my treatment frequency?
You can extend the interval, perhaps from three months to four or five months. Results will be less dramatic, but still effective.
Is there an optimal treatment schedule?
The optimal schedule is whenever you want to return based on when results wear off for you. This is individual and may vary from three to six months.
Who decides wrinkle dosing at Core Aesthetics?
Wrinkle dosing decisions are made by Corey Anderson, AHPRA registered nurse (NMW0001047575), under nurse prescribing scope. Core Aesthetics starts conservatively for first time patients with low to moderate units, then reviews response at two weeks before any top up. Some patients are highly sensitive responders; others need a slightly higher dose to reach the same observable effect. Results vary between individuals, and the two week review is built into the protocol for that reason.
Is it safe to have wrinkle treatment while taking blood-thinning medications or supplements?
Certain medications and supplements, including aspirin, ibuprofen, fish oil, vitamin E and some herbal supplements, can increase bruising risk after any injectable treatment. You will be asked about these at your consultation. In most cases, treatment can proceed, though timing and approach may be adjusted. Always disclose your full medication and supplement list before any injectable appointment.
Why does wrinkle treatment sometimes require a two-week review?
The full effect of prescription neuromodulator takes seven to fourteen days to settle. Reviewing at two weeks allows the treating practitioner to assess whether the dose was appropriate, whether any asymmetry needs addressing, and whether the result aligns with the plan discussed at consultation. It is a clinical checkpoint, not a sales appointment.
