Rejuran is a clear, colourless and odourless solution. It contains polynucleotides or 'PN' for short. The PN are sourced from wild salmon from the Pacific Ocean - Dr Jake has visited the manufacturing plant in South Korea to see the salmon himself! Polynucleotides are purified, bio-active DNA fragments. You can think of these as building blocks that when added together make up strands of DNA.

Injectable polynucleotides are very runny liquids in appearance so they look and feel like a watery serum. They are very different to fillers. They are injected as tiny dots just under the surface of the skin known as the 'dermis'. So immediately after a treatment you can see multiple raised dots all over the skin. This 'bumpy' look to the skin lasts for approximately 48 hours - click here to see what Dr Jake's patient looked like immediately after a forehead and eye treatment

When injected, polynucleotides help stimulate your body's own regenerative and repair mechanisms. Rejuran has been used in Asia since 2014 and over 10 million syringes have been used to date. A huge advantage of polynucleotides is that they do not cause vascular occlusions. This means the risk of blindness or stroke (that is associated with fillers) is essentially zero.

Korean doctors with nearly a decade of experience using Rejuran have noticed how it also seems help improve issues like sensitive skin and redness. It's therefore also a very useful product when used in combination with laser treatments to improve healing and downtime from these treatments, but also to optimise the overall results. Those who suffer with rosacea or melasma can therefore also consider adding Rejuran into their overall skin treatment plan as it can improve the health of the skin barrier (in combination with other treatments).
