Hyperhidrosis treatment using muscle relaxant injections temporarily reduces sweat gland activity in the treated area. Each case is individually assessed at consultation before any treatment is agreed upon.
Why patients in Oakleigh seek hyperhidrosis treatment
Excessive underarm sweating that persists regardless of temperature, season, or exertion level is one of the more disruptive physical conditions a person can live with. Standard antiperspirants, even prescription strength products, provide insufficient relief for many people with primary hyperhidrosis. The result is a daily preoccupation: choosing dark or patterned clothing to disguise marks, avoiding social situations that might trigger sweating, planning ahead in ways that others don’t need to consider.
Core Aesthetics is located on Atherton Road in Oakleigh, within the south east Melbourne corridor. Patients travel from Clayton, Huntingdale, Chadstone, Cheltenham, Carnegie, Bentleigh, Moorabbin, and across the inner south east. The clinic is a short walk from Oakleigh train station on the Glen Waverley and Pakenham lines, and street parking is available nearby.
Consultations are private, thorough, and unhurried. Corey Anderson takes time to understand the full picture of your sweating pattern, treatment history, and medical background before any management option is proposed. No treatment is agreed upon at consultation unless you wish to proceed and have been assessed as clinically appropriate. Some patients attend simply to understand their options before making any decision.
Primary versus secondary hyperhidrosis: why the distinction matters
Hyperhidrosis is classified into two categories. Primary hyperhidrosis has no identifiable underlying cause, the eccrine sweat glands overproduce in response to overactive neural signalling. It typically presents in a focal pattern, affecting one or more specific areas such as the underarms, palms, soles, or face. It commonly begins in adolescence or early adulthood, often has a positive family history, and characteristically worsens with emotional triggers as much as with heat.
Secondary hyperhidrosis is caused by an underlying medical condition (thyroid disorders, diabetes, infections, malignancy) or is a side effect of medication. Secondary hyperhidrosis tends to present more generally, often affecting the whole body rather than focal sites, and may have nocturnal sweating as a feature. It requires investigation and management of the underlying cause before any symptomatic treatment is considered.
Injectable muscle relaxant treatment is appropriate for primary focal hyperhidrosis. At consultation, Corey Anderson takes a careful history to help clarify which category your sweating falls into. If there are features suggesting secondary hyperhidrosis, sudden onset, generalised pattern, associated systemic symptoms, you will be directed to your GP for investigation before any injectable treatment is discussed.
How injectable muscle relaxant treatment reduces sweating
Sweat glands receive their signals through cholinergic nerve terminals, nerve endings that release acetylcholine as the chemical messenger triggering sweat production. Muscle relaxant injections work by temporarily blocking acetylcholine release at these nerve gland junctions. Without that chemical signal, the eccrine glands in the treated area produce significantly less sweat.
The mechanism is the same class of medicine used to relax facial muscles for wrinkle treatment, but delivered to a different anatomical target at different doses. The action is localised, the injected material diffuses within the treatment zone but does not travel systemically in meaningful concentrations. Sweat production elsewhere in the body continues normally. There is no compensatory increase in sweating at other sites.
The effect is temporary. The nerve terminals regenerate over time, and sweat production gradually returns. This means that injectable hyperhidrosis management is a maintenance approach rather than a cure. Most patients experience significant dryness for a period of months, after which retreatment is required to maintain the effect. The expected duration, and how it varies between individuals, is explained in detail at consultation.
The anatomy of axillary sweat glands
The axilla (underarm) contains two types of sweat glands: eccrine glands, which are responsible for thermoregulatory and emotionally triggered sweating; and apocrine glands, which open into hair follicles and are associated with body odour compounds. In primary axillary hyperhidrosis, it is the eccrine glands that are overactive, producing excessive moisture that is often odourless but socially and practically disruptive.
Eccrine glands are distributed at high density across the axillary vault, the roughly oval region of hairless skin at the centre of the armpit. This defined distribution makes the area amenable to injectable treatment: the injection points can be systematically planned to cover the active gland zone without requiring treatment of an excessively large area.
A starch iodine test is sometimes used to visualise which portions of the axillary zone are actively sweating before injection. The test produces a colour change that maps the active sweat regions, allowing injection points to be placed precisely. Whether this mapping technique is used at your appointment will be discussed at consultation based on your presentation and clinical context.
Who may be suitable for injectable hyperhidrosis treatment
Injectable treatment is generally most appropriate for adults aged 18 or over with confirmed primary focal hyperhidrosis affecting the underarms, who have already trialled high strength topical treatments, including aluminium chloride antiperspirants available by prescription, without adequate relief. Clinical guidelines recommend topical management as the first line approach; injectable treatment is typically appropriate when topical options have not provided sufficient control.
Patients who have not yet tried high strength antiperspirants may be advised to do so first. This is not a gatekeeping exercise, it is a reflection of current evidence about treatment sequencing, and also sets a useful baseline against which to compare injectable outcomes.
General health, current medications, and any relevant medical history are reviewed at consultation. Injectable treatment is not appropriate for those who are pregnant or breastfeeding, those with neuromuscular junction disorders such as myasthenia gravis or Lambert-Eaton syndrome, or those on certain medications that may interact with the treatment. Suitability is determined individually for each patient based on a full clinical assessment, it is never assumed.
What the hyperhidrosis consultation involves
The initial consultation at Core Aesthetics for hyperhidrosis is structured, private, and comprehensive. Corey Anderson takes a full history that covers: the pattern of your sweating (which areas, symmetry, onset, duration, severity), the triggers you have identified (temperature, emotion, exertion, specific situations), the impact on your daily life (clothing choices, social activities, work situations), and previous treatments you have tried with their outcomes.
Your current medications are reviewed, as some interact with injectable muscle relaxant treatments. Relevant medical history is taken, including any conditions that may affect the choice or safety of treatment. The treatment area is examined, and the injection zone is discussed.
If injectable treatment is clinically appropriate and you wish to proceed, the procedure, realistic expectations, risks, aftercare, and follow up process are explained in full. You are given the opportunity to ask as many questions as you need. Proceeding on the same day is possible if you are prepared and ready, but there is no expectation or pressure to do so. Some patients prefer to think it over and book a separate treatment appointment at their own pace.
The injection procedure: what to expect on the day of treatment
Treatment begins with a review of the injection zone. A topical numbing cream can be applied if preferred, typically sitting for 20 to 30 minutes before the procedure. Many patients choose to proceed without topical anaesthetic, the needles used are fine gauge, and the injections are shallow and brief. Tolerance varies between individuals, and technique can be adjusted during the session.
The injections are placed at regular intervals across the axillary vault, typically in a grid pattern with points spaced approximately 1 to 2 centimetres apart to ensure even distribution across the active gland zone. Each injection delivers a small volume of solution just beneath the skin surface. Both underarms are treated in the same session. The total procedure time is typically 20 to 40 minutes.
After treatment, minor redness and pinprick marks at the injection sites are normal and resolve within hours. You can leave the clinic and return to your regular activities with specific aftercare instructions. The effect does not appear immediately, most patients notice a reduction in sweating over the following five to fourteen days as the treatment takes effect at the neural level.
Aftercare following axillary hyperhidrosis injections
The aftercare period following hyperhidrosis injections is uncomplicated. The primary principle is to avoid anything that significantly increases circulation or temperature in the treated area for the first 24 hours: vigorous exercise, hot baths or showers, saunas, steam rooms, and heat packs applied to the underarms. This reduces the risk of the injected substance migrating from the intended treatment zone.
Avoid applying deodorants, antiperspirants, or any topical products to the treated axillary skin for the remainder of the day of treatment. From the following day, normal hygiene products can generally be resumed, specific guidance will be provided at your appointment.
Gentle movement of the arms is fine immediately after treatment. You do not need to rest or restrict activity beyond the specific precautions above. Most patients return to work and social activities on the same day. Any unusual symptoms following treatment, significant swelling, bruising beyond minor pinprick marks, or pain beyond mild discomfort, should be reported to the clinic.
Duration of the treatment effect and the maintenance approach
The duration of effect from injectable hyperhidrosis treatment varies between individuals and cannot be predicted with precision before treatment. Published data for axillary hyperhidrosis typically shows a range of four to twelve months, with most patients experiencing significant dryness for six to nine months. Some individuals notice that successive treatments are associated with a progressively longer duration, possibly because the sweat gland activity in the treated area is cumulatively reduced over repeated cycles.
As the effect wanes, sweating typically returns gradually over weeks rather than abruptly. Most patients recognise the early signs and return for retreatment before the condition returns to pretreatment severity. A follow up appointment is generally arranged at four to six weeks post treatment to assess the response and address any areas that may require top up.
This is a maintenance approach, not a cure. There is no permanent injectable equivalent, and the treatment does not alter the underlying neural signalling that drives primary hyperhidrosis. Corey Anderson explains this clearly at consultation, accurate expectations are central to the consultation based model at Core Aesthetics. Patients who want a once only, permanent solution will need to explore surgical options such as sweat gland removal or nerve blocking procedures, which fall outside the scope of this clinic.
Treatment of hyperhidrosis in areas other than the underarms
Axillary hyperhidrosis is the most common presentation managed with injectable treatment at Core Aesthetics, but the same mechanism can be applied to other anatomical areas. Palmar hyperhidrosis (hands) and plantar hyperhidrosis (feet) are occasionally treated with muscle relaxant injections, though these areas present distinct clinical challenges: a higher number of injection points is required for adequate coverage, the areas tend to be more uncomfortable due to greater pain sensitivity, and dose requirements differ from axillary treatment.
Craniofacial hyperhidrosis, affecting the scalp, forehead, or face, is another area sometimes addressed with injectable management. This requires careful consideration of adjacent muscle groups that may be unintentionally affected if injection placement and diffusion are not precisely managed.
The appropriateness of injectable treatment in any site other than the standard axillary zone is assessed individually at consultation, based on the nature of your presentation and the clinical considerations specific to that anatomical area. If you experience sweating that significantly affects multiple areas, bring this to the consultation so the full picture can be considered and the most clinically logical starting point identified.
When injectable treatment is not the right approach
Not everyone who experiences excessive sweating is a suitable candidate for injectable management at an aesthetic clinic. If your sweating has features consistent with secondary hyperhidrosis, sudden onset without a clear trigger, generalised rather than focal distribution, associated night sweats, unexplained weight loss, or other systemic symptoms, the appropriate first step is your GP, not an aesthetic clinic. Masking a symptom without identifying the underlying cause is not responsible clinical practice.
Some patients with primary hyperhidrosis have not yet tried prescription strength topical antiperspirants, which remain the recommended first line treatment. In these cases, it may be more logical to trial topical options before committing to a repeating injectable programme with associated costs and maintenance requirements.
If you attend for a consultation and injectable treatment is not appropriate for your situation, you will be told this clearly and directed towards more suitable pathways. This is what consultation based practice means at Core Aesthetics, the assessment process is genuinely diagnostic, not a formality before treatment is sold. Corey Anderson will give you a straightforward, honest assessment regardless of the outcome.
About Corey Anderson and Core Aesthetics
Core Aesthetics is led by Corey Anderson, a Registered Nurse (AHPRA NMW0001047575, registration since January 1996). Corey’s clinical focus is injectables: anti-wrinkle injections, dermal fillers, and hyperhidrosis management. The practice operates on a low volume, consultation based model, which means each patient receives a thorough individual assessment rather than a high throughput, standardised treatment experience.
Hyperhidrosis management requires careful clinical reasoning, distinguishing primary from secondary sweating, identifying contraindications, assessing which anatomical sites are appropriate for injectable treatment, and setting realistic expectations about duration and maintenance. These are not checkbox exercises; they require clinical experience and genuine engagement with the patient’s history and goals.
All content, advertising, and clinical practice at Core Aesthetics complies with AHPRA’s September 2025 guidelines for registered health practitioners performing nonsurgical cosmetic procedures, and with the TGA Therapeutic Goods Advertising Code. No brand names for prescription medicines are used in clinic materials or treatment discussions with patients.

Clinical accountability and hyperhidrosis treatment review
The hyperhidrosis treatment guidance in “Excessive Sweating Treatment in Oakleigh” reflects how Corey Anderson, AHPRA registered nurse (NMW0001047575), assesses and treats focal axillary hyperhidrosis at Core Aesthetics. Hyperhidrosis is treated as a medical condition rather than a cosmetic concern, with separate consent processes and separate dosing logic from cosmetic anti-wrinkle treatment. Results vary between individuals, sweating reduction onset, magnitude, and duration depend on baseline severity, sweat gland density, and individual response to the active product. The clinical content on this page is calibrated to that variability.
Specific to hyperhidrosis treatment Oakleigh: focal axillary hyperhidrosis treatment is dosed to the individual sweat pattern, identified clinically rather than estimated. Onset is typically a few days to two weeks, magnitude varies by patient, and duration ranges from four to seven months in most cases, outliers exist on both ends. Patients should not expect identical results between treatment cycles; sweat gland response can shift modestly across years of treatment. The patient safety cosmetic injectables page covers related hyperhidrosis content.
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.

Frequently asked questions
Is hyperhidrosis treatment available in Oakleigh?
Yes. Core Aesthetics offers consultation based hyperhidrosis assessment and injectable treatment at its Oakleigh clinic at 12A Atherton Road. A consultation is the required first step to establish whether injectable treatment is appropriate for your situation.
How do I know if my sweating is severe enough to warrant treatment?
There is no fixed threshold. If excessive sweating is affecting your daily life, clothing choices, social confidence, professional situations, or personal comfort, it is worth discussing at consultation. The assessment will help establish whether injectable management is clinically appropriate for you and what realistic outcomes look like.
Do I need a GP referral to book a hyperhidrosis consultation?
No referral is required to book a consultation at Core Aesthetics. However, if your history suggests secondary hyperhidrosis (sweating related to an underlying medical condition), you may be directed to your GP before injectable treatment is considered.
Does the treatment hurt?
The procedure involves multiple small gauge injections across the treatment area. Most patients find the discomfort brief and manageable. Topical numbing cream can be applied beforehand if you prefer, and technique is adjusted during the session based on your comfort.
How soon does the effect appear?
The reduction in sweating typically becomes noticeable five to fourteen days after treatment. The full effect is usually established within two weeks. Onset varies between individuals, some notice a reduction earlier, others take the full two weeks.
How long does hyperhidrosis treatment last?
Duration varies considerably between individuals, typically four to twelve months for axillary treatment, with most patients experiencing results in the six to nine month range. Some individuals find that successive treatments have a progressively longer duration.
Can I exercise and use deodorant after treatment?
Avoid vigorous exercise, heat, saunas, and deodorant application to the treated area for the first 24 hours. From the following day, normal hygiene products can be resumed and gentle activity continued. Full aftercare instructions are provided at your appointment.
Is this a permanent solution?
No. Injectable hyperhidrosis treatment is a maintenance approach, the effect is temporary and retreatment is required to sustain results. There is no permanent injectable equivalent. If permanent resolution is the goal, surgical options (outside the scope of this clinic) are the relevant pathway.
Who manages hyperhidrosis treatment at Core Aesthetics?
Hyperhidrosis treatment is managed by Corey Anderson, AHPRA registered nurse (NMW0001047575). Focal axillary hyperhidrosis is treated as a medical condition with separate consent processes and dosing logic from cosmetic anti-wrinkle treatment. Onset is typically a few days to two weeks, magnitude varies by patient, and duration ranges from four to seven months in most cases. Results vary between individuals; review appointments are scheduled accordingly.
