Rejuran Sydney – the Salmon sperm injectable treatment that’s taking skincare to the next level

natalieabouchar • February 24, 2025

Rejuran, also known as the salmon sperm injectable, is the latest skincare trend taking the aesthetic world by storm. From Hollywood to Sydney, this unique treatment is gaining widespread attention, with celebrities like Kim Kardashian publicly sharing their experiences. But what exactly is a salmon sperm injectable or Rejuran treatment, and why is everyone talking about it?

How does Rejuran or Salmon sperm work?

It’s not just a Hollywood exclusive – this advanced treatment is now available in Australia and has become increasingly popular across Sydney, especially at Privee in the Eastern Suburbs.


Natalie Abouchar, Nurse Practitioner and Director of Privee in Paddington, says:


“The DNA extracted from salmon sperm is processed and purified into fragments referred to as ‘Polynucleotides’, which are the most recent developments in skin repair and remodelling. It has been developed and used in South Korea for almost a decade, but was only TGA approved for use in Australia in 2024.”


“The extracted salmon DNA are important ingredients for skin repair, and work on different levels of the skin to improve everything from collagen to hydration, depressed acne scars, fine lines and wrinkles,” says Natalie.


“Lower down in the dermis, they stimulate cells in our skin called fibroblasts to create more collagen and elastin, which give the skin thickness and tightness.”

Key benefits of a Rejuran treatment in Sydney

  • Increases collagen & elastin : Stimulates fibroblast activity, promoting collagen and elastin production for firmer, more youthful skin.
  • Improves skin texture & tone : Reduces the appearance of fine lines, wrinkles, and uneven skin tone.
  • Enhances hydration : Increases the skin's natural hydration levels, making the skin feel smoother and more supple.
  • Addresses acne scars : Helps reduce the appearance of depressed acne scars by promoting skin regeneration.

Target areas for Rejuran treatment in Sydney

Rejuran can be injected to various areas of the face, including:

  • Under-Eye Area : Rejuran i is designed for delicate areas like the under eyes, helping reduce dark circles, fine lines, festoons and improve skin laxity. 
  • Overall Skin Health : Treats concerns like loss of elasticity, dull skin, fine lines, and enlarged pores.

Rejuran i, which has a lower viscosity than standard Rejuran, is ideal for those seeking treatment of the under-eye area. It has shown excellent results in reducing dark circles and fine lines around the eyes, and is one of the most requested Rejuran Sydney treatments for rejuvenation.. See our Case Study here.

Salmon sperm Rejuran – How does Rejuran differ from other aesthetic treatments?

Unlike many traditional aesthetic treatments that work by filling in wrinkles or acne scars, Rejuran regenerates the skin at a cellular level. It stimulates the body’s natural healing processes, improving tissue regeneration in damaged or ageing skin. This makes Rejuran a unique and effective option for long-lasting skin rejuvenation.


Studies have shown that the polynucleotides in Rejuran not only help improve depressed skin areas but also promote tissue repair in the surrounding skin, resulting in natural and healthier-looking improvements — one of the reasons Rejuran Sydney has become so popular for clients seeking rejuvenation without added volume.

Are there any side effects?

While most people experience minimal side effects after a Rejuran treatment, every person will experience small raised bumps immediately after the treatment. This is just the liquid being injected very superficially under the surface of the skin. The bumps go away within 12-24 hours as the liquid gets reabsorbed. You may also notice redness, pin point bruising and generalised swelling for a few days. These responses usually subside within a few days. If necessary, antihistamines and cool compresses can help alleviate swelling. It’s recommended to avoid blood thinning medication and alcohol for a few days before and after the treatment. 

Rejuran is composed of bio-compatible DNA fragments that are very similar to the body’s own DNA, making it a safe option with minimal risk of adverse effects. Even patients with allergies to fish or salmon are able to use this product. It is approved by the Australian Therapeutic Goods Administration (TGA) and is used in over 20 countries worldwide. With over 10 million syringes sold globally, no significant adverse events have been reported.

Rejuran works by stimulating the skin’s natural regenerative abilities. For optimal results, a course of three treatments is recommended, with sessions spaced 2-4 weeks apart. After the initial treatment, a maintenance session every 6-12 months will help preserve skin health and rejuvenation.
