What is Rejuran?

Rejuran is a concentrated injectable polynucleotide that is extracted from wild salmon sperm DNA. Polynucleotides are long chains of amino acids found naturally in the skin, where they play important roles in skin remodeling at cellular level.  

The crucial ingredient extracted from this salmon DNA is called PDRN, and it’s something that’s naturally present in new, fresh skin tissues.

By synthesising it into an injectable, we can replicate the regenerative process for skin. The DNA of salmon is used specifically because it contains an exceptionally high percentage of nucleic acids compared to other fish. 

Technicians extract the long DNA strands from salmon cells, and these DNA strands are very rich in polynucleotides. The strands go through hydrolysis to break them down into much shorter strands called PDRN complexes. 

These purified PDRN complexes are then used to formulate Rejuran as a cosmetic product for use in skin rejuvenation. 

The key polynucleotide component in Rejuran ultimately comes from salmon sperm DNA. Hence the nickname ‘salmon sperm injections’, even though the final product contains only processed polynucleotides rather than actual sperm cells or DNA. 

The PDRN extracted this unique way provides nutrients that can enhance skin cell renewal and stimulate collagen production when injected into the skin.

Where can Rejuran be used?

Rejuran is intended for anywhere on the body where we want the skin to heal and rejuvenate, and to reverse signs of ageing.

It’s commonly used as a treatment for scarring, inflammation concerns like rosacea, as well as signs of ageing such as fine lines and wrinkles, loss of tone, or uneven texture.  

Rejuran is placed into the dermis, the layer of skin underneath the epidermis. Product placement is typically administered to areas such as the face, neck, hands or décolletage, but it’s not limited to these zones.

This treatment can improve skin density because you’re kicking your own natural collagen production into gear, which leads to improved elasticity. And, as we’re repairing damaged skin cells, it rejuvenates the skin’s texture and laxity, so there are smoothing and tightening benefits. 

Treatment is highly successful around the eye area for general skin tightening and collagen stimulation, to firm, hydrate and brighten. You can also treat the entire face, neck and décolletage for a comprehensive rejuvenation.
