Rejuran is a brand of skincare cosmetics and injectables in Singapore which is developed in South Korea. The key ingredient of the skincare line is PDRN (Polydeoxyribonucleotides), while the key ingredient of the injectables is PN (Polynucleotides). These ingredients are extracted from salmon DNA and are over 99.9% identical to human DNA, making them highly bio-compatible with a very low risk of reactions. Rejuran works from within by stimulating a cascade of biological processes to rejuvenate the skin. This "baby skin" treatment stimulates the skin's natural regenerative abilities, improving skin health, radiance, and youthful appearance.
The polynucleotides in Rejuran supply the building blocks for new DNA synthesis and act as scaffolding for cell proliferation and extracellular matrix deposition. When Rejuran is injected into the skin, it introduces polynucleotides, which trigger the production of fibroblasts. Fibroblasts are responsible for synthesising collagen, elastin, glycosaminoglycans, and glycoproteins – essential for maintaining the skin’s structure, elasticity, hydration, and overall resilience. In addition, skin regeneration is aided by the wound-healing process, which stimulates growth factors, increases circulation, and reduces inflammation.
Rejuran improves skin texture and enhances hydration and plumpness.
Rejuran is suitable if you have any of the following skin conditions:
Rejuran is versatile and can be used in the following areas:

This depends on your skin’s concern. After a detailed consultation with your doctor at Bay Aesthetics Clinic and Medispa, a personalised treatment plan will be recommended. This may involve using different types of Rejuran injections (e.g., Rejuran Healer for the full face, with Rejuran I (Eye) for the undereye area).
Your skin will be assessed, so a bespoke treatment plan will be created to suit your needs. Next, your skin will be cleansed, and a numbing cream (anaesthetic) will be applied to the targeted area to minimise discomfort during the procedure. Rejuran will be administered manually or through a series of fine microinjections into the dermal layer of your skin.

Yes, Rejuran can be effectively combined with other treatments to enhance overall results i0n skin rejuvenation. These treatments include Hydrafacial, Laser, Botox, and Fillers.
Unlike traditional skinboosters primarily focusing on hydration, Rejuran offers a more comprehensive approach to skin rejuvenation. In addition to improving skin hydration, Rejuran stimulates collagen production, repairs damaged skin cells, and has anti-inflammatory effects, leading to a more youthful and radiant complexion.
While both Rejuran and dermal fillers are injectable treatments, they serve different purposes. Dermal fillers add volume and smooth out deep wrinkles and folds, while Rejuran works from within to improve overall skin health, texture, and elasticity. Rejuran is not intended to volumise or sculpt the face like dermal fillers.
