Anti-wrinkle injections are the most common non-invasive, injectable cosmetic treatments. They are effective in treating fine lines and wrinkles by relaxing targeted muscles. They work by temporarily stopping muscle contractions that contribute to facial expressions. Smaller or higher doses can be used depending on whether the patient wants to preserve some movement or have no movement at all. Examples of commonly treated areas include frown and forehead lines, crows feet, gummy smiles and masseters.

Patients seeking an experienced cosmetic practice in South Melbourne are invited to schedule an in-person consultation with Dr Parvin Khinda (a.k.a Dr PK) or her experienced cosmetic nurse injectors to discuss anti-wrinkle injections at Kaya Cosmedica.

What are anti-wrinkle injections?

Over time, the movement of our facial muscles and the effects of the ageing process causes wrinkles to form and deepen. Anti-wrinkle treatment injections contain a toxin from the bacteria Clostridium that temporarily blocks the signals from nerves to muscles, stopping them from contracting, resulting in less movement and the reduction or smoothing out of existing wrinkles. Injectables are one of the most popular anti-ageing skin treatments because they are minimally invasive, convenient, and effective in refreshing your look with natural-looking results.

Due to restrictions of the Australian Therapeutic Goods Administration, the brands of anti-wrinkle injections used at Kaya Cosmedica cannot be advertised. In Australia, four brands are currently available. They each contain the toxin extracted through different proprietary methods for the bacterium Clostridium botulinum. You can learn more about the surprising discovery of this ingredient in our blog, 7 Things You Didn’t Know About Anti-Wrinkle Injections.


Prior to its use in cosmetic procedures, this substance  was primarily used for the treatment of strabismus, a condition characterised by crossed eyes. In the late 1980s scientists observed that administering this substance around the eye area induced muscle relaxation, consequently enabling the realignment of the eye movements. Subsequent research unveiled the cosmetic and medical advantages of this treatment, expanding its uses.

Anti wrinkle injections have a prominent role in the cosmetic industry delivering outcomes from rejuvenated skin by reducing forehead lines and crows feet to the management of medical conditions such as hyperhidrosis (excessive sweating) and bruxism (jaw grinding).

How do anti-wrinkle injections work?

Anti-wrinkle injections contain a substance which is a powerful neurotoxin that inhibits muscular contractions. It works at the neuromuscular junction (where the nerves and muscles meet) and prevents the release of acetylcholine – a neurotransmitter that causes muscle contraction. This process results in muscle relaxation, which reduces the appearance of wrinkles and creates a smoother and more refreshed appearance.

Variable amounts are injected precisely into targeted muscles to reduce the appearance of wrinkles. Compared to surgical options, this treatment is cost-effective, lower risk, and accommodating to those who have busy schedules or simply do not want downtime. Although the results are not permanent, they are long-lasting and can last longer with ongoing treatment.

At the South Melbourne cosmetic and skin clinic, anti-wrinkle injections are more than a cosmetic solution for unwanted lines. They are also used for facial lifting (e.g. brow lift) change facial proportion (eg. slim the face) and treat a gummy smile. As Kaya Cosmedica is a doctor-led clinic, it is also used to treat a variety of medical conditions including bruxism (teeth grinding) migraines and tension headaches, correcting asymmetries from conditions such as Bells Palsy, excessive sweating (hyperhidrosis) and hayfever.

What areas can we treat with anti-wrinkle injections?

When paired with the effects of stress, sun damage, and genetics, our skin takes on many signs of tiredness and age, often leading to a worn, fatigued or even angry appearance that does not reflect our true character. Anti-wrinkle injections help to slow the effects of ageing and produce a more youthful and refreshed expression.

Areas treated include:

  • Frown lines between the eyebrows
  • Forehead lines
  • Crow’s feet at the corners of the eyes
  • Lines around the nose (bunny lines)
  • Upper lip lines (smoker’s lines)
  • Downturned mouth
  • Dimpled chin
  • Neck lines (platysmal bands)
  • Gummy Smile
  • Nasal Droop
  • Nasal Flare
  • Masseters/jawline contouring
  • Platysma
  • Temporalis
  • Trapezius/Neck pain
  • Calves

Anti-wrinkle injections can also be used to:

  • Lift parts of the face. For example, by elevating the brows to correct  heavy brow line, or by lifting the jawline by treating the platysma muscle in the neck.
  • Reduce excessive muscle function.  For example, reducing a “gummy” smile by relaxing the overactive muscles around the lip and nose.
  • Alter facial proportions. For example, slimming the face by relaxing the muscles that create a ‘bulky’ or ‘square’ facial structure.
  • Manage teeth grinding (bruxism) by relaxing the masseter muscle. This will also reduce squareness and release tension in the jaw.
  • Assist with TMJ dysfunction – a pain condition of the jaw joint (TMJ) caused by various muscles including the masseter.
  • Manage migraines by relaxing and reducing tension in various facial and neck muscles (such as the temporalis, trapezius and occipitalis).
  • Treat excessive sweating (hyperhidrosis) by stopping the sympathetic nerves from stimulating the sweat glands.
  • Reduce the effects of hay fever. This is done by spraying botulinum toxin into the nasal passages to reduce symptoms such as nasal congestion, itching and sneezing.
