Rejuran is an injectable treatment containing polynucleotides (PNs). It is used in cosmetic practice for concerns such as skin texture, scarring, or changes around the eyes.

​

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 who are looking to address skin texture, laxity or the appearance of scarring, and who are interested in a treatment focused on skin quality. Suitability is assessed at your consultation.

​

What to expect

After a discussion of your history and goals, the skin is cleansed and a topical anaesthetic may be applied. A series of small injections is placed into the treatment area. Appointments usually take around 30 to 45 minutes, and a course of treatments spaced a few weeks apart is generally recommended.

​

Preparation and downtime

Arrive with clean skin and let me know about any medications or supplements you take. Small bumps, redness, swelling or bruising are common in the first few days and usually settle on their own. Most people return to their usual activities the same day, although you may prefer to plan around social events.

​

Risks and possible complications

Any treatment that involves injecting into the skin carries risk, and it is better to know what to expect. It is normal to have raised bumps at each injection point together with redness, swelling, tenderness and bruising. The bumps usually settle within a day or two and bruising within about a week, so it is worth planning around social or work commitments. Less commonly you may notice itching, lumpiness that takes longer to settle, or temporary pigment changes at the injection sites, which are more likely in deeper skin tones. Infection is uncommon but possible whenever the skin is broken, and warmth, spreading redness, increasing pain or discharge should be reported to us promptly. Rare complications include an allergic reaction, persistent nodules, scarring, and injury to a blood vessel which can damage the skin. Rejuran is derived from salmon DNA, so it is not used if you have a fish allergy. It is also avoided in pregnancy and breastfeeding, where there is active skin infection or inflammation in the area, and where there is a history of keloid scarring. A course of sessions is normally needed, changes build gradually rather than appearing straight away, results 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.

 

Please note

An in-person consultation is required before any treatment. Results may vary from person to person. Potential risks, benefits and suitability are discussed with you before any treatment is provided.

Common questions

What is Rejuran?

An injectable treatment containing polynucleotides, used in cosmetic practice for concerns such as skin texture, fine lines and skin quality. It's placed into the skin itself rather than used to add volume.

How is it different from a dermal filler?

A filler is used to restore or add volume and holds its own shape. Rejuran isn't a volumising treatment — it's aimed at the condition and quality of the skin. People are often looking for one when they ask about the other, which is a conversation worth having before you book anything.

What does the appointment involve?

Numbing cream first, then a series of small injections across the treatment area. Allow around 45 minutes including numbing time.

What's the downtime?

Small raised bumps at each injection point are expected and usually settle within 24 to 48 hours. Bruising is possible, particularly under the eyes. Plan for a quiet couple of days rather than an event.

How many sessions will I need?

Generally a course of three, spaced two to four weeks apart, with maintenance afterwards. A single session isn't really the treatment.

I have a fish allergy — does that matter?

Yes, and please tell me. The polynucleotides used in these treatments are derived from salmon, so a fish allergy is something I need to know about before we discuss it as an option at all.

When would I notice a change?

This is a gradual treatment rather than an immediate one, and it's usually assessed over the course rather than after a single session. If you want something with a visible result the same week, this isn't it, and I'll say so.
