Rejuran and Polynucleotides: The Korea Trend, Assessed for Indian Skin

Polynucleotide skin treatments — sold online as the "salmon sperm facial", and delivered at The Aesthetic Edge using the Korean-developed Rejuran line — became widely known through Korean aesthetic clinics. They are micro-injections of purified, salmon-derived DNA fragments that signal the skin's own repair. The mechanism is well described; the long-term comparative evidence is still building, and that is worth knowing before you book.

This piece is written for a reader in India deciding whether a treatment that arrived through Korean skincare content deserves their money and their skin.

Where did this trend actually come from?

Korean aesthetic clinics, where polynucleotide treatments have been popular for several years before most people outside the country had heard of them. The "salmon DNA" framing travelled outwards with the treatment through skincare content, picked up the more sensational nickname on the way, and arrived in India as a name rather than as an explanation.

The treatment itself is now available well beyond Korea. Geography is not what makes it work or not work — what matters is that a doctor has assessed your skin before deciding it is appropriate for you.

What is the actual claim being made?

Narrower than the internet suggests, which is a point in its favour rather than against it. Polynucleotides do not fill, plump or lift. Nothing is placed to change your contour, and your features stay exactly as they are.

What is claimed is an improvement in skin quality — hydration, elasticity, texture and fine lines — arriving gradually over the weeks after each session, because the DNA fragments act as a signal that prompts your own repair and regeneration processes rather than doing the work themselves. A typical course is two to four sessions, two to four weeks apart.

If the version you read promised a facelift in a syringe, that version was selling something the treatment does not claim.

How strong is the evidence?

Honestly stated: this is a newer treatment and its evidence base is still building. Early studies and clinical experience are encouraging for hydration, elasticity and fine lines. Long-term comparative data — the kind that tells you how it performs against older treatments over years rather than months — is more limited than it is for the treatments it is often compared with.

That is not a reason to avoid it. It is a reason to be sceptical of anyone describing it in absolutes, and to weigh it as a promising newer option rather than a settled one. A clinic willing to tell you where the evidence thins out is generally a clinic worth listening to on the rest.

Does it suit Indian skin?

Here is the careful answer, and the carefulness is the point.

Nothing about this treatment is documented as tone-specific, and we are not going to invent a claim that it does something particular for deeper skin tones or for pigmentation. What it targets is skin quality — dullness, thin or crepey texture, fine lines, poor elasticity — and those concerns are not the property of any one complexion.

What can be said plainly is what the treatment is and is not. It is an injectable, not a device: there is no laser, no light and no heat involved anywhere in it. And it adds no volume, so it does nothing to the shape of a face.

Whether it suits your skin is a clinical judgement, made by a doctor who has examined it and taken your history — not something to be settled by your skin tone, by a video, or by this article. That assessment is exactly what the consultation is for, and it is also where you should expect to be told if something else fits better.

What the trend loses in translation

Three things reliably go missing between a Korean clinic and an Indian timeline.

That it is not a facial. The popular name has people expecting a treatment bed and a mask. It is a series of small injections through fine needles after numbing cream. Expect small raised bumps and redness at the injection points, usually settling within 24 to 48 hours, with bruising possible at any point and more likely if you take blood-thinning medication.

That one product does not fit everyone. Rejuran is a line with more than one formulation aimed at different concerns and areas. Which of them fits what you are asking about is confirmed by your doctor at the consultation rather than defaulting to a single option.

That it is a course, not an appointment. Results build across sessions spaced weeks apart. Someone expecting a visible change on the drive home is going to be disappointed by a treatment that was working normally.

How does it sit beside what is already on the menu here?

Skin boosters and Profhilo have been on Indian clinic menus for far longer and are hyaluronic acid based — they hydrate by holding water within the skin. Polynucleotides take a different route, prompting your own repair and collagen response instead of supplying hydration directly.

Neither is the upgrade of the other. The useful question is whether your central problem is dryness, in which case direct hydration addresses it, or overall skin quality and repair, where the signalling mechanism does more of the work. That is not a question this page can answer for you, and any clinic answering it before examining your skin is guessing.

What to ask before booking anything trending

Five questions that separate a considered treatment from a purchase.

Who is injecting, and are they a doctor? Depth, dose and placement are clinical decisions here, not stylistic ones. Were you asked about allergies — and specifically about fish allergy, given what the product is derived from? Were your medical history and any skin conditions actually reviewed? Were you told what the treatment does not do? And were you given a realistic timeline, or a promise about the weekend?

You should also expect to be told when you are not a candidate. Treatment is deferred or declined with a known fish or product allergy, an active skin infection or open wounds in the area, certain skin conditions, and during pregnancy or breastfeeding. And if your concern is really volume loss, sagging or deep folds, this is the wrong tool — a different plan would serve you better.

When to ring the clinic afterwards

Do not sit at home deciding what something means. Allergic reactions and infection are uncommon but possible with any injectable.

Report increasing pain, heat, spreading redness or any unexpected reaction promptly, rather than waiting for your next scheduled session. The same goes for swelling that worsens instead of settling, discharge, a fever, or anything that does not match what you were told to expect. None of these is common, all are simpler dealt with early, and none is yours to grade alone.

Cost, and where to start

There is no single figure to publish, because what you pay depends on the area being treated and how many sessions your skin actually needs. You will have the full plan and its cost before anything is booked. The consultation is ₹500, waived against treatment.

If a trend brought you here, let a clinical assessment decide whether it stays relevant to you. Book a consultation at Indiranagar or Bellandur and get a straight answer about whether this treatment addresses what is actually bothering you.
