What Is Rejuran and How Does It Work?
Rejuran is becoming one of the most talked-about treatments in Australian skin clinics, not because it promises dramatic before-and-after photos, but because it quietly addresses a core concern shared by many people today: how to repair and maintain healthy, functional skin in a changing and often harsh environment. Rather than adding volume, freezing muscles or altering facial shape, Rejuran works on a cellular level to improve skin quality over time. With a foundation in regenerative science and a focus on supporting the body’s natural healing processes, it’s no surprise that both clients and clinics are paying closer attention to what Rejuran offers.
At the heart of Rejuran is a substance called PDRN, short for polydeoxyribonucleotide. This ingredient is derived from the DNA of wild salmon, a source chosen not for novelty but because of its structural similarity to human DNA and its well-documented effects on tissue regeneration. When Rejuran is injected into the skin using a series of microinjections, it begins working at the dermal level to activate fibroblasts. These cells are responsible for producing collagen, elastin and other key components that determine the firmness, hydration and resilience of the skin. Instead of producing an immediate physical transformation like fillers or wrinkle-relaxing products, Rejuran gradually restores function, elasticity and hydration to the skin’s foundation.
Why Rejuran Is Especially Relevant for Australian Skin
The treatment is increasingly relevant in Australia, particularly in regions like Tasmania where environmental stressors are consistently high. Clients in Hobart and surrounding areas are often exposed to intense UV radiation, dry wind, and seasonal changes that lead to chronic dehydration, redness, and compromised skin barrier function. Many of these issues don’t respond well to cosmetic creams or superficial treatments alone. Rejuran offers a method for strengthening the skin’s core structure from within, helping it cope better with these stressors while supporting long-term repair.
What to Expect During a Rejuran Treatment
So what is the Rejuran treatment experience actually like? At clinics such as Heart Aesthetics Hobart, the process begins with a thorough consultation and skin assessment. Clients meet with a trained cosmetic nurse to discuss their goals, which may include reducing fine lines, improving skin texture, fading post-acne scarring or simply enhancing hydration in high-stress areas such as the under-eyes, jawline or neck. During this appointment, the nurse will also assess the skin’s current condition and screen for contraindications, including allergies to seafood, which is essential since Rejuran is derived from marine DNA. Assuming the client is a suitable candidate, the treatment process is explained in full, with an emphasis on expected outcomes and timelines. One of the things that distinguishes Rejuran from other injectables is its realistic, gradual effect. It’s not a one-and-done session, but a series of treatments that deliver results through cumulative cellular improvement.
Procedure, Comfort and Recovery
The session itself is straightforward. The client’s skin is cleansed and prepped, and a topical numbing cream is applied to ensure comfort during the procedure. Using a fine needle or microinjection device, the nurse administers Rejuran into the upper dermal layer of the skin. The sensation is brief and mild for most people, similar to other cosmetic microinjection treatments. Areas commonly targeted include the cheeks, temples, under the eyes, jawline, forehead and sometimes the neck or décolletage. The entire session generally takes between thirty and forty-five minutes, depending on the number of areas treated. After treatment, there may be some mild redness or swelling at the injection sites. These effects typically resolve within twenty-four to forty-eight hours. Clients are advised to avoid excessive heat, sun exposure and strenuous activity during the first two days after treatment. Most people return to normal routines quickly, and makeup can be worn after twenty-four hours if desired.
How Fast Does Rejuran Work?
What follows is a repair response that unfolds gradually. The body begins to utilise the PDRN to stimulate cell turnover and collagen production. While individual results vary, many clients notice changes in skin texture, tone and hydration within the first one to two weeks. The skin often feels smoother and appears more radiant, with less visible pores and a more even surface. Improvements continue to build over a standard protocol of three sessions, spaced four weeks apart. Maintenance treatments once or twice a year are recommended to keep results consistent. What’s unique about Rejuran is that the results are not dependent on the product remaining in the skin. Instead, the treatment works by triggering your own biological functions, meaning the skin itself becomes healthier and more stable over time.
Why Clinics Are Combining Rejuran with Other Modalities
Clinics in Australia are incorporating Rejuran into broader treatment plans because of its versatility. It pairs well with skin needling, also known as clinical microneedling, as well as LED therapy. These combinations can be particularly effective for clients recovering from acne, post-inflammatory pigmentation, or other types of skin injury. When used alongside these modalities, Rejuran accelerates healing and supports deeper collagen remodeling. But it’s also strong enough to be used on its own. Many clients choose to stick with Rejuran as a stand-alone treatment to simplify their skin journey and reduce dependency on aggressive or high-maintenance interventions.
Rejuran vs Fillers and Muscle Relaxants
It’s also worth noting that Rejuran does not interfere with facial volume, symmetry or movement. It will not make the cheeks look fuller, the lips more projected or the forehead smoother. That’s because its goal is different. It works from the inside to strengthen skin that is fragile, dehydrated, inflamed or weakened by environmental exposure. This makes it especially appealing to people who are not interested in volume-based enhancements or expression-free aesthetics. Rejuran supports natural function, and the results reflect that. The skin retains its softness and movement, while becoming more resilient and even-toned.
Ideal Candidate Profile
For many Australians, this aligns with a growing interest in subtle, maintenance-based cosmetic care. Rather than chasing trends or attempting to reverse signs of ageing overnight, clients are looking for treatments that support long-term skin health. Rejuran fits into this shift because it offers visible improvement without compromising the natural look and feel of the face. It’s also well-suited to clients who have tried cosmetic products or procedures in the past and experienced irritation, breakouts or suboptimal results. Since Rejuran is anti-inflammatory and designed to support the skin barrier, it’s often better tolerated than other active treatments.
Who Should Not Receive Rejuran?
Of course, Rejuran is not suitable for everyone. The most important consideration is seafood allergy, which is an absolute contraindication. Clients who have a known sensitivity to marine products should not receive Rejuran. It’s also not appropriate during pregnancy or breastfeeding, and it should only be administered by trained professionals in a clinical setting. Reputable clinics such as Heart Aesthetics Hobart provide full transparency about product ingredients, safety data and expected outcomes. Their nurse-led approach ensures clients are supported before, during and after each session.
Pricing and Treatment Plans
Pricing varies depending on the area treated and the number of sessions needed. A full-face protocol usually includes three appointments, while additional areas such as the neck, chest or hands can be added at an extra cost. Some clients opt for Rejuran in combination with other non-volumising therapies for a more comprehensive approach to skin strengthening. During the consultation process, all pricing and treatment pathways are clearly outlined so clients can make fully informed decisions without sales pressure.
Why Rejuran Represents a New Direction in Cosmetic Care
In summary, Rejuran offers a science-backed, biologically active method of improving skin from within. It represents a growing category of treatments focused on regeneration rather than enhancement, prioritising strength, hydration and long-term repair. In Australia, where climate and environmental stress continue to impact skin health, treatments like Rejuran are likely to play a bigger role in personalised cosmetic care. Whether you are managing skin sensitivity, recovering from acne, addressing early signs of ageing or simply seeking to support your skin’s natural function, Rejuran may offer a powerful, low-intervention solution worth exploring.
