Rejuran Healer has become an increasingly popular option for patients in Singapore seFine lines and wrinkles are common skin concerns that develop gradually with age, stress, repeated facial expressions, sun exposure, and everyday lifestyle factors. In Singapore’s tropical climate, high UV exposure and humidity can further accelerate skin ageing, making early signs such as creasing, dullness, and reduced elasticity more noticeable.
As a result, there is growing interest in regenerative aesthetic treatments that go beyond simply “filling” lines or temporarily masking wrinkles, and instead focus on improving the skin’s underlying health. One such treatment is rejuran, which has gained popularity for its ability to support skin repair and improve overall skin quality at a deeper, biological level.

What is Rejuran?
Rejuran is a polynucleotide (PN)-based injectable skin treatment derived from highly purified salmon DNA fragments. These polynucleotides are biocompatible with human skin and function as bioactive molecules that interact with the extracellular matrix to support dermal repair processes. In clinical aesthetic use, rejuran is not intended to provide volumisation like hyaluronic acid fillers, but instead acts as a bioremodelling agent that influences cellular behaviour in the dermis.
At a biological level, PN fragments are thought to modulate inflammation, enhance fibroblast activity, and support tissue regeneration in damaged or ageing skin. This creates a more favourable environment for dermal repair, allowing gradual restoration of skin integrity rather than immediate structural change. Over time, this can translate into improved skin resilience, texture refinement, and reduction in early signs of photoageing, particularly in areas where the skin barrier has been compromised.
How Rejuran Works on Skin Repair
The primary action of rejuran lies in its ability to support dermal repair at a cellular and extracellular level. Once injected into the superficial dermis, polynucleotides interact with skin cells and the surrounding extracellular matrix, creating an environment that favours tissue recovery. This process is not mechanical or volumising; instead, it is biologically driven, focusing on restoring skin function over time.
One of the key mechanisms involves the modulation of inflammation. Chronic low-grade inflammation is a known contributor to accelerated skin ageing and collagen degradation. By helping to regulate inflammatory pathways, Rejuran supports a more stable dermal environment, which is essential for effective repair. At the same time, it is thought to enhance fibroblast activity, these are the cells responsible for producing collagen and elastin, the structural proteins that maintain skin firmness and elasticity.
As fibroblast function improves, the skin gradually undergoes remodelling, with increased synthesis of collagen and improved organisation of dermal fibres. This leads to progressive strengthening of the skin structure rather than immediate visible changes.
Rejuran and Collagen Support in Ageing Skin
Collagen loss is one of the primary structural changes that leads to the formation of fine lines and wrinkles. From the mid-20s onwards, the skin’s natural collagen production begins to decline, while existing collagen fibres become more fragmented and disorganised due to intrinsic ageing and extrinsic factors such as UV exposure and pollution. In this context, rejuran is used as a bioregenerative treatment aimed at supporting the skin’s ability to restore a healthier dermal matrix over time.
Rather than directly replacing collagen, Rejuran works by improving the biological environment in which collagen is produced. By enhancing fibroblast activity and supporting dermal repair pathways, it encourages more efficient synthesis of new collagen and helps improve the structural integrity of existing dermal tissue. This gradual remodelling process can lead to improved dermal density, better elasticity, and a reduction in the depth and visibility of fine lines.
Importantly, collagen regeneration with Rejuran is not immediate. The process occurs progressively as the skin cycles through repair and renewal phases. With repeated treatment sessions, patients may notice that the skin appears firmer, more resilient, and less crepey, particularly in delicate areas where early signs of ageing are most visible.
Common Treatment Areas for Fine Lines and Wrinkles
In clinical practice, rejuran is commonly used in areas where the skin is thinner, more delicate, and more prone to early structural ageing. These regions tend to show fine lines earlier due to reduced dermal support, repetitive muscle movement, and cumulative environmental exposure.
Typical treatment areas include:
- Periorbital area (around the eyes): Crow’s feet and under-eye fine lines, where the skin is particularly thin and collagen depletion is more evident
- Forehead: Expression lines that gradually become more static over time due to repeated muscle activity
- Peri-oral region (around the mouth): Fine lines associated with repetitive movement, volume loss, and reduced skin elasticity
- Neck: Horizontal lines and crepey skin texture, often linked to natural ageing and chronic sun exposure
Across these areas, Rejuran is used to improve overall skin quality rather than change facial structure.
Expected Results from Rejuran for Fine Lines and Wrinkles
Results from rejuran are typically gradual and progressive rather than immediate. Because the treatment works by supporting dermal repair and collagen remodelling, visible improvements usually develop over several weeks as the skin undergoes natural regeneration cycles. Patients often first notice subtle changes in skin hydration and texture, followed by a smoother and more refined surface appearance.
With continued treatment, fine lines may appear softer, and the skin can look more resilient with improved elasticity and a healthier overall glow. These changes tend to be subtle and natural, rather than dramatic, making Rejuran suitable for patients who prefer understated rejuvenation.
Conclusion
Fine lines and wrinkles are a natural part of skin ageing, but modern regenerative treatments like rejuran offer a way to support skin health beyond surface-level correction. By working at a biological level to enhance dermal repair and collagen activity, it helps improve overall skin quality gradually, resulting in smoother, firmer, and more resilient skin over time.
For individuals seeking subtle and natural-looking rejuvenation, it can be a useful option as part of a long-term skin maintenance plan. To find out whether Rejuran is suitable for your skin concerns, you may schedule a consultation or make an enquiry at:
