What Is Rejuran and Why Is Everyone Talking About It?

If you have been researching skin treatments recently, you have probably come across the name Rejuran. It has gained a huge following in South Korea and is now one of the fastest-growing skin treatments in Australia. But what exactly is it, and why is it generating so much interest?

What Is Rejuran?

Rejuran is an injectable skin treatment made from polynucleotides (PN), which are fragments of DNA derived from salmon. Before that puts you off, the science behind it is well established. Polynucleotides have been used in medicine for decades for their ability to promote tissue repair and reduce inflammation.

When injected into the skin, Rejuran works at a cellular level to stimulate your body's own repair processes. It promotes collagen production, improves skin elasticity, enhances hydration from within, and helps repair damaged or thinning skin.

Unlike treatments that fill or freeze, Rejuran focuses on improving the quality and health of the skin itself. The goal is skin that looks and feels better because it genuinely is better, not because something has been added on top of it or used to mask what is underneath.

What Does It Treat?

Rejuran is most commonly used for fine lines and early signs of ageing, dull or tired-looking skin that lacks radiance, uneven skin texture or enlarged pores, skin that has been damaged by sun exposure over time, thinning skin that has lost its firmness, and acne scarring where the skin needs to be rebuilt rather than filled.

It is particularly popular among people in their late 20s to 40s who are looking for something that improves their skin quality long-term rather than delivering an instant but temporary cosmetic change.

How Is It Different from Other Treatments?

Rejuran sits in a different category from most cosmetic injectable treatments. It is not a cosmetic injectable that adds volume to the face. It is not a muscle-relaxing treatment that targets wrinkles caused by expression. And it is not a traditional skin booster that simply adds hydration.

What makes Rejuran different is that it works by triggering the skin's own regenerative processes. It encourages the body to produce more collagen and repair damaged cells, rather than introducing a foreign substance to create a visible change. The result is improvement that builds gradually over multiple sessions and comes from within the skin itself.

This is why Rejuran is often described as a skin healing treatment rather than a cosmetic one. The visible improvements, including smoother texture, better tone, increased firmness, and a more even complexion, are a byproduct of the skin actually becoming healthier.

What Does the Treatment Involve?

Rejuran is administered through a series of micro-injections into the skin, typically across the face. A numbing cream is applied beforehand to minimise discomfort. The treatment takes around 30 to 45 minutes.

Most people need a course of three to four sessions, spaced about four weeks apart, to see the full benefit. After the initial course, maintenance sessions every three to six months are usually recommended to sustain the results.

Downtime is minimal. Some redness and small bumps at the injection sites are normal and typically resolve within 24 to 48 hours.

Who Is It For?

Rejuran suits a wide range of skin types and concerns. It is a good option if you want to improve your skin quality without dramatic cosmetic changes, you are noticing early signs of ageing and want to address them proactively, your skin looks tired, dull, or uneven despite a good skincare routine, or you have sun damage or mild scarring that you want to address from the inside out.

A consultation with a qualified practitioner is the best way to determine whether Rejuran is appropriate for your skin and your goals.
