Rejuran (PN Skin Booster)

How it works

Rejuran contains polynucleotides (PN), fragments of DNA purified from salmon. When injected into the skin in many tiny points, they are thought to support the skin's own repair processes and hold water, which may improve texture, fine lines, thin-looking skin and some scarring. Because it is placed in the skin rather than beneath it, it does not add volume. Results build over a course of several sessions and vary by person, and the skin may look slightly dotted for a day or two.

Who it may suit

• Thin, fragile or crepey skin
• Fine lines and a rough, uneven surface
• Shallow acne scarring as part of a wider plan
• Skin recovering from other procedures, as advised by the doctor
• The delicate under-eye skin, when the doctor judges it appropriate

The treatment day

1. Assessment. The doctor checks your skin, asks about allergies, particularly to fish, and discusses areas and the number of sessions.
2. Product check. The sealed box, brand label and lot number are shown before the ampoule or syringe is opened.
3. Numbing and injection. After numbing cream, the product is injected in many small points across the area.
4. Aftercare review. You receive instructions and an idea of how the skin will look over the next few days.

Aftercare

• Avoid rubbing the skin and keep hands off the injection points.
• Skip saunas, hot baths and strenuous exercise for about a day.
• Use gentle cleansers, moisturizer and sunscreen.
• Hold off on makeup until the points have calmed, as advised.
• Report persistent redness, swelling or any signs of infection.

Things to know first

• Small bumps, redness and bruising commonly settle within one to two days, though bruising can last longer.
• People with fish allergy should disclose it before treatment.
• Pregnancy, breastfeeding, active infection or inflammation in the area are reasons to postpone.
• Blood-thinning medicines raise the chance of bruising.
• Benefits are gradual and vary by person, with a course of several sessions typical.

What to check before booking Rejuran in Gangnam

Start with the product itself. Rejuran is a specific branded product, but polynucleotide boosters from other makers are also sold under similar-sounding names. Ask which one is being used, and ask to see the sealed box with its label and lot number before it is opened. A clinic that offers a salmon booster without naming a brand is not necessarily doing anything wrong, yet you are entitled to know what you are paying for.

Technique is the second point. The depth and spacing of injections affect both comfort and results, and the skin under the eyes needs particular care. Ask who injects and how often they do this treatment. A doctor who explains why a certain area is suited, and who discloses that results are gradual and vary, is handling expectations responsibly.

Finally, examine the quote. A clear one states the product, the amount per session, the number of sessions and which areas are included. Be cautious about large prepaid courses sold before your skin has been assessed, or about add-on mixes that appear at the payment counter. A second consultation to compare is a low-cost way to confirm the plan is based on your skin.
