Rejuran salmon DNA injections
Rejuran is an injectable skin rejuvenation treatment that has been popular in Asia, particularly South Korea, and is now available in Australia. It is sometimes called “salmon DNA injections” because of the source of its key ingredient.
Rejuran is a biostimulator, which means it works by supporting your skin’s natural regeneration rather than adding volume. It helps activate fibroblasts—the cells that produce collagen and elastin—which are important for maintaining skin firmness, elasticity, and hydration.
This treatment may help improve overall skin quality, including texture, hydration, and firmness. Rejuran is often used to address concerns such as fine lines, uneven skin texture, enlarged pores, and scarring, including acne scars. Individual results can vary depending on your skin condition and personal factors.
What Is Rejuran?
Rejuran is an injectable skin treatment designed to support your skin’s natural repair processes. It is made from polynucleotides, a type of molecule naturally found in the skin that plays a role in cellular repair and skin remodelling.
The formulation used is regulated for clinical use in Australia and administered by a qualified healthcare professional. Salmon is used because it naturally contains a high concentration of these molecules. The product is carefully processed so that it does not contain sperm cells or intact DNA—only refined polynucleotides are used.
When administered, the treatment is intended to interact with normal skin processes over time. For this reason, it is sometimes referred to as a “skin rejuvenation” or “skin repair” treatment.
Suitability for Rejuran and the expected results are always assessed during a consultation with a qualified medical practitioner to ensure it is appropriate for your individual skin needs.

Frequently Asked Questions
​
1. What is Rejuran and how does it function?
Rejuran is a skin rejuvenation treatment made from polynucleotides (PN), which are purified molecules derived from salmon DNA. When injected into the skin, these molecules are intended to support your skin’s natural repair processes. This may help stimulate collagen and elastin production, which can improve skin thickness, elasticity, and overall skin health over time.
2. What should I expect during a Rejuran clinical session?
During treatment, tiny injections are made into the superficial layers of the skin. To make the procedure comfortable, a topical numbing cream is usually applied beforehand. After the session, you may notice small bumps at the injection points. This is a normal part of the process and usually settles within 24 to 72 hours as the product is absorbed.
3. What clinical concerns can Rejuran address?
Rejuran is commonly used to support skin quality and address concerns such as:
-
Fine lines and early wrinkles
-
Enlarged pores
-
Uneven skin texture or scarring
Specialised formulations, such as Rejuran I for delicate eye areas or Rejuran S for targeted scarring, may also be used depending on your individual needs.
4. How many sessions are recommended for the intended results?
Typically, three sessions spaced three to four weeks apart are recommended to achieve the intended improvements. Because Rejuran works by supporting the skin’s natural processes, results develop gradually over several weeks. Maintenance treatments are usually suggested every six to twelve months to help sustain the benefits.
