Rejuran®, also known as 婴儿针 (in Mandarin), is an anti-aging injectable skin booster that promotes collagen production, accelerates skin repair, and improves skin elasticity and turgidity. With its high concentrations of salmon-derived polynucleotides, Rejuran® activates the skin’s self-regeneration properties to effectively reverse the signs of skin aging.

How does Rejuran® work?

Rejuran® is composed primarily of highly purified concentrations of polynucleotides extracted from wild salmon. These active polynucleotides have anti-inflammatory properties which benefit the skin by inducing skin healing, stimulating cell growth, and improving the integrity of the extracellular matrix. Rejuran® activates the self-regenerating capacity of the skin and enhances collagen and elastin production to restore skin hydration and elasticity. These processes collectively rejuvenate the epidermis and the dermis to reveal a younger-looking, bright skin.

The polynucleotides derived from salmon DNA closely resemble human DNA, making Rejuran® a safe, highly compatible injectable with no adverse effects on the skin. 

What are different types of Rejuran®?

Three variations of Rejuran® are available in Singapore. Each formulation is designed to target specific skin concerns and deliver optimum results. All Rejuran® formulations contain highly purified salmon-derived polynucleotides.

Rejuran® Healer is specifically formulated for damaged and aged skin as it promotes total skin healing and rejuvenation. The Rejuran® Healer restores skin integrity, enhances hydration and elasticity, reduces fine lines and wrinkles, and refines pores. This type of treatment also has anti-inflammatory effects which help optimize skin recovery.

People with sunken scars and uneven skin will benefit most from Rejuran® S. This formulation has a higher viscosity which is suitable for the sunken and uneven surfaces of the skin. Rejuran® S promotes collagen production and tissue remodeling to treat acne scars and smooth out the skin.

Rejuran® I specifically targets crow’s feet, fine lines, wrinkles, and dark circles around the eyes. Rejuran® I is formulated with a lower viscosity that is safe and suitable for the thin skin around the eye area. Rejuran® I has been shown to reduce crow’s feet and wrinkles with no adverse effects.

Rejuran® is a safe and non-invasive injectable treatment. To make the procedure more comfortable, we apply our premium numbing cream onto the patient’s skin prior to the procedure. Strong painkillers are also available upon request, without any additional charge. After applying the numbing cream, Rejuran® is manually injected into the dermis via a nano needle. The manual technique is preferred over the injector gun as it gives better results and ensures that most of the Rejuran® gel is administered into the skin.

Rejuran® treatment has minimal side effects, such as small bumps that may appear after the injection but these will disappear within a day. In some cases, few needle marks may appear but these will resolve spontaneously in a couple of days. In rare instances, bruising may appear but this will also resolve in a few days.

Yes, Rejuran® can be combined with other treatments. Rejuran® works synergistically when combined with energy-based devices. It enhances the results of other treatments and at the same time reduces the downtime of energy-based devices. 

Ideal treatment combination for Rejuran® are with Microneedling radiofrequency, fractional lasers and skin boosters. Additionally, Rejuran® can be combined with Rejuran I and Rejuan S in the same treatment session to target specific concerns.
