Rejuran salmon DNA injections
Rejuran is an injectable skin rejuvenation treatment, and it’s now approved and available for Australia after years of popularity and success in Asia, particularly South Korea.
It also goes by the moniker of ‘salmon sperm injections’ or ‘salmon DNA injections’ due to the unique way the ingredients are sourced.
It’s a biostimulator, which is a type of treatment that works by triggering your skin’s own natural collagen production. It does this by stimulating the cells that produce collagen, called fibroblasts. This process promotes true hydration, and regeneration of collagen and elastin.
These properties result in slowing down the ageing process, boosting hydration of the skin, treating fine lines, wrinkles, pores and textural changes, and reducing scarring, including acne scarring.
The main active ingredient in Rejuran is Polynucleotide Rejuran (PDRN). This polynucleotide complex is extracted from salmon sperm DNA.
The polynucleotides in Rejuran provide building blocks that boost collagen and elastin production in the skin. These are proteins that help maintain skin structure and elasticity.
By increasing collagen and elastin synthesis, Rejuran helps improve skin hydration, texture, brightness and overall appearance, and can help reduce fine lines and wrinkles.
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 remodelling at cellular level.
The crucial ingredient extracted from this salmon sperm 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. It’s why this treatment is also referred to as ‘baby skin injections’.
The sperm 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 sperm 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 injectable.
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.
