Dermal Fillers

Dermal fillers are becoming more popular due to their instant results and intermittent lifespan. Permanent fillers are associated with higher risks, and if there’s an undesirable result, surgical intervention to remove them is generally required. Non-permanent dermal fillers are reversible, produce quick results, short procedure time and have minimal down time as most patients are generally able to return to work immediately after.

The Ageing process is an inevitable aspect of life, which cannot be completely stopped over the long term; however it can be significantly slowed down so that ageing maybe graceful. In many cases, people are able to actually look younger than they currently do, and with the right aesthetic clinician, we can help maintain a youthful appearance for longer, and delay the ageing process. 

Hyaluronic Acid (HA)

The most common types of fillers are the Hyaluronic Acid (HA) group which are reversible. Other common fillers include the Non reversible and temporary fillers that generally last up to 1 year, such as Collagen/ biostimulator injections.

Hyaluronic Acid HA is a Glycosaminoglycan. It plays an integral role in healthy skin and decreases with photoaged (skin damage caused by sun rays) skin. This leads to a weakened structural support, associated with the HA to collagen and elastin, and reduces the skins ability to bind to water. This results in the skin being unable to provide sufficient support for blood vessels, elastin and collagen , and is unable to sustain itself in good health.

HA Fillers are made up of molecules (glycosaminoglycans) which exist naturally within the body where 50% of our bodies HA is found within the skin.

How long do dermal fillers last?

It is quite difficult and almost impossible to state how long fillers last and therefore there is only a ‘soft’ classification which is based on different factors such as patients metabolism, age, area being treated and type of filler being used.

popular filler treatments

Collagen (PLLA)
Caclium Hydorxylate (CaHa)
Polycaprolactone Based fillers (PCL)
Fat grafting

Collagen Stimulating Injections


PLLA is compatible and degradable by our bodies, and stimulates the production of collagen. PLLA increases the thickness of the skin and produces healthier, stronger and more vibrant skin.
Additional information: PLLA activates fibroblast activity resulting in autologous neocollagenesis, and significant growth of type I collagen in the skin. The PLLA is gradually degraded by the body into water and carbon dioxide,

Calcium Hydroxylate


CaHA is also compatible and degradable by our bodies, and stimulates the production of collagen. CaHA is semi solid, strongly cohesive implant injected under the skin.
Once injected, the gel progressively disappears and is replaced by the growth of soft tissue. This acts as a scaffold that promotes your own body to increase its production of tissue, which is important as our body progressively loses its ability to increase tissue production as we age.

Extra information; Once the CaHA is injected into the skin, the particles induce fibroblastic growth and calcification. If injected onto bone, its bioceramic properties allows this to help restore volume associated with bone loss, ie the product is able to interact and integrate with bone and eventually become totally replaced with newly formed bone. CaHA is native to the body with no antigenicity.

This product is commonly used around the world for long lasting correction of moderate and severe wrinkles/ folds, and to treat viral/immune disorders associated with significant fat loss around the face.

CaHA acts as a filling/ volumizing agent, and usually clinically disappears in 9- 12months. However, longer lasting results are seen for a much longer period than this, as their ability to stimulate your own body to produce more tissue increasing volume and skin thickness.

Polycaprolactone Based Fillers


PCL is a naturally absorbed medical material aoorived for usage across the world for cosmetics, sutures and orthopaedic implants. In cosmetics, PCL is used to stimulate collagen production for up to 13 months after treatments and commonly used by surgeons and experienced Aesthetic practitioners.

Extra information 
PCL is composed of 70% aqeous carboxymethylcelullose (CMC) and is a biodegradable filler used to stimulate collagen production. It had a variety of different polymer chain lengths providing different levels of longevity and strengths. Most common form, its used as a one off treatment with 4 duration formulations used across different regions, S – 1 year, M 2 years, L – 3 years, E – 4 years.



Most practitioners and patients prefer to have some form of pain relief. There are multiple options available for your convenience;

  • Initially, a topical numbing agent such as emla cream or lmx, is applied to the area of treatment. Common additional forms of pain relief:
  • Local anaesthesia using a nerve block is a fantastic method to achieve almost no pain at all, however this does vary based on individual. This is quite similar and sometimes used interchangeably with the term dental block. Most dermal fillers also contain local anaesthesia and hence any pain experienced during treatment generally tends to improve throughout
  • Laughing gas (also known as happy gas or Nitros oxide) is also available.
  • Applying ice to the area prior to treatment can also help reduce the pain, and applying ice after the procedure also helps reduce the swelling.

Right After The


After treatment Some bruising, redness and swelling maybe present and self resolve over the next few days. Generally the swelling tends to provide a slightly enhanced effect due to the increased volume associated with this, which tends to disappear eventuate into a more natural appearance. Some patients tend to enjoy the swelling effect, however others may prefer the more natural effect.
