Collagen

Collagen is one of the main structural proteins in the skin, and the amount and quality of it changes with age, sun exposure and other lifestyle factors. Several of the treatments offered in the clinic aim to support the skin's own collagen production over time.

Risks and possible complications are set out further down this page and we ask that you read them before booking.

 

Who it may suit

People interested in skin quality, firmness and texture, who are willing to work through a course of treatments rather than expecting change from a single appointment. Suitability is assessed at your consultation.

What to expect

At consultation I assess your skin and discuss which collagen-focused options may be appropriate, such as skin needling, threads or injectable skin treatments, along with the home care that supports them. A plan is usually made over several months with review points along the way.

Preparation and downtime

Preparation and downtime depend on the specific treatment chosen and are explained to you before you go ahead. Sun protection and consistent skincare are important throughout.

Risks and possible complications

Collagen focused treatments are medical treatments and they carry risk, so it is important you know what can happen before you decide. Because a plan may combine needling, threads or injectable skin treatments, the risks depend on what is used, and the specific ones for your plan are set out for you in writing before you consent. The individual treatment pages on this site describe them in more detail as well. Across all of these treatments you can expect redness, swelling, tenderness, bruising, dryness or flaking, and small marks at the treated points, generally settling over a few days to a couple of weeks. Less commonly there can be lumps or areas of firmness, prolonged swelling, uneven results, a temporary breakout, or changes in skin pigment that are more likely in deeper skin tones and with sun exposure afterwards. Infection is uncommon but possible whenever the skin barrier is broken, including reactivation of cold sores, and any warmth, spreading redness, increasing pain, pus or fever should be reported to us promptly. Rare complications include scarring, a persistent nodule or granuloma, an allergic reaction, nerve irritation causing numbness or altered movement, and injury to a blood vessel which can damage the skin. These treatments are generally avoided in pregnancy and breastfeeding, where there is active infection or inflammation in the area, in people taking or recently finished on oral isotretinoin, with a history of keloid scarring or poor wound healing, and alongside certain autoimmune, bleeding or immune conditions. Collagen change is slow by nature, so a course over several months is normally needed, results build gradually rather than appearing straight away, they vary from person to person and some people notice little difference. Josie will go through the risks that apply to you, how they are managed and what to do if you are concerned afterwards, before you give consent. You are welcome to call the clinic on (02) 9331 7228 with any questions.
