Cosmetic Fillers & Injectables

Mr Kenton-Smith has included the use of cosmetic fillers in his practice for over 9 years.  Our patients get beautiful, aesthetically pleasing results relatively inexpensively and with very little recovery time.  The results of cosmetic fillers, in the hands of a skilled injector, are subtle, flattering and yet non permanent.  Patients often have others tell them they are looking "well" after an injectables treatment. 

At 5 Naseby Street we hold regular Injectables clinics which are run by our warm and skillful injector, Dr. Mary Irvine.  Mary is a G.P. with a special interest in cosmetic injectables and a keen aesthetic eye. 

When you come to see Dr. Irvine, she will discuss any issues you are concerned with and then explain the solutions available to you.  You will also be told the costs of various treatments.  You will then need to decide whether or not you would like the treatment.  If you decide not to go ahead with any treatment, that is fine, you will just need to pay your consultation fee of $50. If you decide to go ahead, your consultation fee will be incorporated into the cost of your treatment.   If you decide to book your treatment for another day your consultation fee will come off your eventual bill. 

We believe we are one of the only clinics in New Zealand offering our patients a doctor injector, rather than a nurse, who is overseen by a plastic surgeon.  We believe that the combined skills of these two doctors result in the best aesthetic results achievable.

What can you expect from a treatment of cosmetic fillers?

  • A softening of your facial lines

  • Enhancement of your beauty

  • Natural results

  • Subtle results

  • Maximisation and enhancement of your own natural beauty

  • The eye of onlookers will be redirected to notice the youthful aspects of your face

  • Volumised cheeks to restore that youthful look

  • Lips: recreate the shape and lift of youth, without overstating your case

These treatments are not permanent. If you have not had them done before, you can try them, safe in the knowledge the effects will last a few months. Your old look with gradually return.

Our aim is for you to feel and look great. We don’t aim for a " Hollywood " overkill look. We work with you to identify the areas of main concern, and plan the best treatment, or mix of treatments, to achieve the look you want.

We advise a conservative approach to give a natural look.

We believe these treatments are best given on a Friday, so that when you return to work the following week, any temporary swelling will have returned to normal, and no one will guess you have been treated!


Hyalonuric Acid Based Dermal Fillers

Hyalonuric acid is a naturally occurring component of our skin. One of the physical features of hyalonuric acid is that it is hydroscopic – that is, it binds water to itself. This is one of the important features that makes these products so successful in cosmetic treatments. It hydrates your skin from the inside. The hyalonuric acid is a complex sugar in a clear gel form. The filler is injected into areas of the face where lines require plumping, or volume needs to be restored.

If this is your first treatment, and lines are quite deep, we may plan a 2-part treatment three months apart, to get the optimal effect.

Simply putting in more product does not more effectively eliminate lines. You may replace lines with lumps! Instead, taking a 2-stage approach means the skin has stretched, hydrated and softened, and is more responsive, thus lines are softened naturally, with a longer duration improvement.

You just keep looking better and better. Instant results, giving a natural, instant lift.

There are some side effects, most commonly firmness, lumps, bruising or redness at injection site. These are temporary and generally resolve within a few days. 


Restylane was launched in 1996, and has already been used in more than 2 million treatments.

Restylane is a long standing hyalonuric acid dermal filler with a proven safety track record.

Restylane is made by QMed in Sweden, and is used in more than 70 countries worldwide.

Restylane has specific products designed to be used in different facial areas. Restylane Lipp has large rounded particles to volumise for fuller lips.

Perlane is used for deeper volume restoration in cheeks.

Restylane comes in 0.5 ml and 1 ml syringe units, so there is no waste if a smaller amount is needed to treat a small area, or for touch-ups.

Restylane is genetically engineered and this makes allergic reactions extremely rare.

The product generally lasts six months to one year.

Restylane is an off-the-shelf injectable product used for filling contour defects on the face and also enhancing lips.

Restylane is sometimes injected under local anaesthetic but now contains the local anaesthetic, Lidocaine, so injecting is as close to pain-free as possible.

Restylane is most commonly used to enhance the lips and also to soften the nasolabial folds that run down from the lower corner of the nose, around the mouth. It can also be used for heavy frown lines.



Juvederm has been available in Europe since 2000, approved for use in the US 2006, Australia 2006, and New Zealand since 2008.

Juvederm is manufactured using Hyalcross technology, involving a high degree of cross linking, which slows the metabolic breakdown of hyalonuric acid, so results should last for up to a year.

Juvederm now contains Lignocaine local anaesthetic, so injecting is as close to pain-free as possible but it can also be injected under local anaesthetic.

Juvederm was developed by Allergan – the company who brought Botox to the world.

Juvederm has different products for different applications. Juvederm Ultra, Ultra Plus, and now Voluma, to add deeper volume to cheeks, for a rounded, natural look.
