7 Things to know about Rejuran Healer in Korea

A highly popular treatment not only in Korea but also in other Asian countries like Singapore, is the Rejuran Healer injection developed by a Korean pharmaceutical company, Pharmaresearch.

As we age, our skin ages too which is only sped up by external stimuli and stress. When the skin ages, collagen and elastic fiber in the skin are diminished and our dermis layer gets thinner and lose elasticity. This is why aged skin feels thinner and we get wrinkles.

So came the Rejuran Healer injection in 2014 and became increasingly popular. It uses a substance called PN(Polynucleotide) to regenerate skin tissue, make our skin thicker and increase its elasticity. It reduces wrinkles and brings back the skin to its younger form.

Here are answers to 7 questions you should want to know about the Rejuran Healer.

(When more than 10 Nucleotides, which are in DNA, are linked together, it is called a PolyNucleotide)

3. What is the difference between the Rejuran Healer and the 'Salmon Injection' in Korea?

The 'Salmon injection' is composed of PDRN, which like the PN is a fragment of DNA. But PN are typically longer threads than PDRN.
