Rejuran is a treatment we’re asked about a lot at Coastal Goddess — usually after someone has seen it online described as a “salmon DNA” or “salmon sperm” injection. The name tends to grab the attention, but what actually matters is what it is, what it sets out to do, and whether it’s a sensible choice for your skin. Here’s a straightforward explanation.
Rejuran is a type of injectable known as a polynucleotide skin booster. Polynucleotides (often shortened to PN) are short chains of DNA, and in Rejuran’s case they’re purified from salmon. Unlike a dermal filler, it isn’t designed to add volume or change the shape of your face. It’s a skin-quality treatment — the aim is to support the condition of the skin itself.
Injected into the skin in tiny amounts, polynucleotides are thought to help create a better environment for the skin to hydrate and repair. Clinical experience and research suggest PN may help the skin hold moisture and support its own production of collagen and elastin over a course of treatments. It works gradually rather than instantly, which is why it’s given as a series rather than a single session.
Rejuran is most often used to improve overall skin texture, hydration and the appearance of fine lines — commonly around the under-eyes, cheeks and neck. Some people also consider it as part of a plan for acne scarring or dull, tired-looking skin. What it can realistically achieve depends on your skin, your age and your goals, so results vary from person to person. It isn’t a one-size-fits-all fix, and it’s rarely the whole answer on its own.
Rejuran is usually given as a short course of treatments spaced a few weeks apart, with occasional maintenance sessions afterwards. Each treatment involves a series of small injections, and numbing cream is used to keep you comfortable. Afterwards you may notice small bumps, redness or mild bruising at the injection points, which typically settle within a day or two. Downtime is generally minimal, and you’ll be given clear aftercare advice to follow.
Rejuran is a medical treatment, so it isn’t suitable for everyone — for instance, it isn’t used during pregnancy or breastfeeding, or where there are certain allergies or skin conditions. The honest answer to “should I have it?” only comes after a proper assessment. At your consultation we’ll look at your skin, talk through what’s realistic, and let you know whether Rejuran, a different treatment, or a combination is the better path. We’d always rather tell you something isn’t worth it than recommend a treatment you don’t need.
