Aesthetic treatments Glossary, Terms Explained

The language of aesthetic treatment can feel confusing, particularly for clients who are new to this area. This glossary provides plain English definitions of the terms most commonly used in discussions about wrinkle treatments, facial volume treatment and nonsurgical facial rejuvenation. It is written by the team at Core Aesthetics in Oakleigh as an educational reference, not as medical advice.

For personalised clinical advice, a consultation at Core Aesthetics is always the appropriate starting point. Book a consultation to discuss what may be appropriate for your individual situation.

“Good information changes the quality of the decision.”

A

AHPRA

The Australian Health Practitioner Regulation Agency. The national body responsible for registering and regulating health practitioners in Australia. Practitioners who administer prescription injectable treatments are regulated by AHPRA and must hold current registration. At Core Aesthetics, all clinical activity is conducted in compliance with AHPRA guidelines.

Asymmetry

A difference in appearance between the two sides of the face. Some degree of facial asymmetry is normal and present in virtually all faces. In cosmetic treatment, asymmetry may be a presenting concern that treatment aims to address, or it may be a consideration in treatment planning to avoid creating or worsening imbalance.

B

Wrinkle injectable

The active ingredient in wrinkle injectable products. A purified protein that temporarily blocks nerve signals to targeted muscles. In Australia, specific brand names of wrinkle injectable products are restricted from advertising in consumer facing material by the TGA. The specific product used is discussed openly during your individual consultation at Core Aesthetics.

Bruxism

Habitual clenching or grinding of the teeth, often occurring during sleep. Bruxism is associated with enlargement of the masseter muscle over time and may cause jaw tension, headaches and dental wear. Injectable treatment of the masseter can reduce muscle activity in suitable candidates and is available at Core Aesthetics following an individual assessment.

C

Cannula

A blunt tipped flexible tube used as an alternative to a sharp needle for some facial volume treatment placements. Because the tip is blunt, it displaces rather than punctures tissue, which can reduce the risk of bruising in certain areas. Whether a needle or cannula is used is a clinical decision based on the treatment area and individual anatomy.

Corrugator supercilii

One of the primary muscles responsible for frown lines. The corrugator supercilii pulls the brows towards the midline, creating the vertical creases between the brows associated with frowning and concentration. It is a primary target in wrinkle treatment for frown lines.

D

Facial volume treatment

A category of injectable prescription product used to restore volume, improve facial structure or soften hollows and lines. Most facial volume treatments used in Australia are hyaluronic acid based. They are regulated as prescription medicines by the TGA and may only be administered by a qualified health practitioner following an individual assessment.

Dynamic lines

Expression lines that are visible during facial movement but not at rest. wrinkle treatment primarily addresses dynamic lines. Over time, dynamic lines may become static, visible even when the face is at rest.

E

EEAT

Experience, Expertise, Authority and Trust. A framework used by Google to assess the quality and credibility of health and medical content online. At Core Aesthetics, content is authored by Corey Anderson, AHPRA registered nurse, and reflects clinical knowledge and experience in aesthetic treatment practice.

Eccrine glands

The primary type of sweat gland in the human body, responsible for temperature regulation through sweat production. In hyperhidrosis treatment, injectable product is used to temporarily block the nerve signals that activate eccrine glands in the treated area, reducing sweat production.

F

Frontalis

The broad muscle that runs across the forehead and is responsible for raising the brows. wrinkle treatment of the frontalis can soften forehead lines, but must be carefully dosed to avoid causing brow heaviness or a flattened forehead appearance. At Core Aesthetics, forehead treatment is always assessed alongside frown line treatment to ensure balanced upper face results.

H

Hyaluronic acid

A naturally occurring polysaccharide found in skin and connective tissue. Used as the base material in most facial volume treatments. Biocompatible and reversible, hyaluronic acid based volume treatments can be dissolved with hyaluronidase if required.

Hyaluronidase

An enzyme used to dissolve hyaluronic acid based facial volume treatments. Used where treatment correction or reversal is required. At Core Aesthetics, hyaluronidase is available for cases where dissolution is clinically indicated.

Hyperhidrosis

A medical condition characterised by excessive sweating beyond what is needed for normal temperature regulation. See our dedicated page on what is hyperhidrosis for a full overview.

L

Ligamentous retaining structures

Fibrous bands that attach the overlying skin and soft tissue to deeper facial structures including bone and the SMAS. These structures play a role in maintaining facial tissue in its youthful position. As they stretch and weaken with age, tissue descent and volume redistribution can occur.

M

Mandible

The lower jawbone. The mandible provides the skeletal foundation for the lower face. Age related resorption of the mandible contributes to changes in lower face contour and jaw definition over time.

Masseter

One of the primary muscles of mastication, located at the angle of the jaw. The masseter can become enlarged due to habitual clenching or grinding, contributing to a wider, heavier lower face appearance. Injectable treatment of the masseter can reduce its bulk in suitable candidates. See our page on masseter treatment for more.

N

Nasolabial fold

The groove or line that runs from the side of the nose to the corner of the mouth. Nasolabial folds exist on all faces and deepen with age. They are often a downstream effect of mid face volume loss rather than a primary concern. See our page on nasolabial fold treatment.

O

Orbicularis oculi

The circular muscle that surrounds the eye and controls blinking, squinting and smiling. Repeated contraction of the orbicularis oculi at the outer corners of the eye creates crows feet. wrinkle treatment targets the lateral portion of this muscle in crows feet treatment.

P

Periorbital area

The area around the eye, including the upper eyelid, lower eyelid and the skin at the outer and inner corners of the eye. The periorbital area contains very thin, delicate skin and is an anatomically complex zone for injectable treatment.

Ptosis

Drooping of the upper eyelid. Brow ptosis refers to descent of the brow. Both can be caused by poorly placed or over dosed wrinkle treatment and are complications to be avoided through careful assessment and conservative dosing. At Core Aesthetics, upper face treatment is always assessed in the context of brow and eyelid position.

S

Static lines

Lines that are visible in the skin even when the face is completely at rest. Static lines have typically developed from long term dynamic line activity combined with changes in skin elasticity. They may require a combination of wrinkle treatment and facial volume treatment to address adequately.

SMAS

The superficial musculoaponeurotic system. A layer of connective tissue and muscle in the face that plays an important role in facial structure and ageing. Changes in the SMAS layer and the fat compartments associated with it contribute significantly to the visible signs of facial volume loss and descent.

T

Tear trough

The groove that runs from the inner corner of the eye along the border between the lower eyelid and the upper cheek. When this area becomes hollow or shadowed, it creates a persistently tired appearance. See our page on tear trough treatment.

TGA

The Therapeutic Goods Administration. The Australian government body responsible for regulating therapeutic products including the prescription medicines used in aesthetic treatment. At Core Aesthetics, all treatments are delivered in compliance with TGA regulations.

V

Vascular anatomy

The network of blood vessels in the face. Understanding vascular anatomy is a critical component of safe injectable practice. Injection near or into facial blood vessels can cause serious complications. At Core Aesthetics, all injections are performed with an understanding of relevant vascular anatomy and appropriate risk mitigation.

About This Information

The information on this page is provided for general educational purposes. It is not a substitute for clinical advice and does not constitute a recommendation that you proceed with any particular treatment. Aesthetic treatments are prescription medical procedures. They carry risks that vary between individuals and that must be assessed and discussed in a clinical context before any treatment decision is made.

At Core Aesthetics, Corey Anderson assesses every patient individually. The consultation is the point at which your specific anatomy, medical history, and goals are evaluated together. No treatment is offered at a first appointment, and no treatment is appropriate for everyone. This page is a starting point, a way to understand what is involved before you decide whether a consultation is the right next step for you.

If you have questions about anything on this page or about whether treatment might be appropriate for your situation, you are welcome to call the clinic or book a consultation at no obligation.

This page provides clinical information about Aesthetic treatments Glossary, Terms Explained. It is intended for adults aged 18 and over who are considering aesthetic treatment and want to understand the clinical process, suitability factors, and what to expect from a consultation based practice. All treatment decisions at Core Aesthetics follow individual assessment, no treatment is offered at a first appointment without a separate consultation. Results vary between individuals and are reviewed at follow up.

How To Use This Glossary in a Consultation

The terms collected in this glossary are the working vocabulary of aesthetic treatment practice. They are not jargon for jargon’s sake. Each describes a specific anatomical region, clinical concept, technique, or product class that has a precise meaning in clinical use. Patients who arrive at a consultation with a working understanding of the terms are better positioned to ask precise questions and to evaluate the answers.

The glossary is not a substitute for clinical assessment. Knowing what the tear trough is does not tell a patient whether their under eye concern is anatomically a tear trough problem. Knowing what hyaluronic acid is does not indicate whether a hyaluronic acid based product is the right tool for a particular face. The function of the vocabulary is to make the consultation more productive, not to replace it.

A few terms warrant particular care. The phrase ‘natural results’ carries no fixed clinical meaning. It is used by patients to describe an aesthetic preference, by practitioners to describe a treatment philosophy, and by marketing copy to mean almost anything. At consultation, the practitioner’s job is to ask what specifically the patient means: subtle, undetectable, harmonious with their existing features, or simply not over treated. Each interpretation has different operational implications. Similarly, ‘volume restoration’ is sometimes treated as synonymous with volume treatment, but the two concepts are distinct: volume treatment can restore lost volume in some contexts, but it can also reshape contour, support adjacent tissue, or correct asymmetry without acting primarily as a volume agent.

Brand names are deliberately absent from the glossary. Under section 42DL of the Therapeutic Goods Act 1989, advertising of prescription only therapeutic goods to the general public is prohibited in Australia. Aesthetic treatment products in the categories most relevant to this clinic, including botulinum toxin and hyaluronic acid treatment products, sit within Schedule 4 of the Poisons Standard and are subject to that prohibition. The glossary uses generic and class terms because they are the appropriate level of patient facing information.

Where a glossary term raises a question that this page does not answer, the appropriate next step is a consultation, conducted by Corey Anderson, Registered Nurse, AHPRA NMW0001047575. The vocabulary is the starting point for that conversation. The clinical decisions are made within the consultation itself.

Concepts Often Misunderstood By Patients New To Aesthetic treatments

Several concepts in aesthetic treatment practice are genuinely complex and are commonly misunderstood by patients arriving for a first consultation. A short orientation to the most consequential of these can sharpen the consultation conversation.

Volume is not the same as plumpness. Volume treatment can add visible plumpness to an area, but its more skilled use is structural: restoring lost support to descended tissue, reinforcing a contour that has softened, or shifting the proportional relationships between facial regions in a way that changes how the face reads overall. Patients who conceptualise volume treatment primarily as a plumping agent often request treatment in areas where structural support would serve them better.

Wrinkle treatment does not address skin quality. The treatment relaxes specific muscles, which reduces the dynamic line formation those muscles produce. Skin texture, dermal collagen, hydration, and pigmentation are unaffected by it. Patients who arrive expecting wrinkle treatment to produce a smoother skin surface are sometimes surprised to learn that the visible improvement they want requires a different category of treatment, often delivered by a different provider.

Brand names are not interchangeable with class names. Several different products in the facial volume treatment category share a common active ingredient (hyaluronic acid) but differ in cross linking density, particle size, and clinical handling characteristics. The practitioner’s selection of a specific product for a specific area and patient is a clinical decision based on the assessment. Patients sometimes ask for a particular brand by name; the appropriate clinical response is to discuss whether the request reflects a clinically meaningful preference or an exposure to brand marketing material that is not relevant to their individual case.

Conservative dosing is not the same as undertreatment. The conservative dosing principle that runs through every appointment at Core Aesthetics is a structured approach to titration: under treat at the first appointment in a cycle, document the response at the two week review, and adjust upward where the assessment supports it. This produces fewer regret outcomes than maximalist dosing and produces them less frequently. It is not a position of generic caution. It is an operational discipline.

Patients who arrive with a clear vocabulary find the consultation more efficient. Patients who do not are not penalised; the practitioner’s job includes translating clinical concepts into language the patient can use comfortably.

Where Glossary Vocabulary Stops Being Useful

The vocabulary collected here is useful for orientation but reaches a natural limit at the consultation door. Knowing what the term ‘mid face descent’ refers to does not tell a patient whether their individual mid face is descending in a way that warrants treatment, what the realistic options are for addressing it, or whether the patient is a clinical candidate for those options. The clinical judgment is the work of the consultation, and the vocabulary is the framework that supports the conversation rather than a substitute for the conversation itself. Patients are encouraged to bring questions to the consultation rather than to attempt to self diagnose from the glossary.

When To Bring Glossary Terms Into Other Conversations

Patients sometimes find the vocabulary useful in conversations with other healthcare providers, particularly when discussing prior cosmetic treatment with a general practitioner, dermatologist, or other specialist. Using accurate terms (orbital rim, mentum, glabellar complex, hyaluronic acid volume treatment, neuromodulator, hyaluronidase) supports clearer documentation and reduces the risk of misunderstanding when treatment history is being communicated across providers. The terms in this glossary are the working vocabulary of aesthetic treatment practice in Australia; they are recognised by other clinicians regardless of the specific clinic the patient was treated at.
