PDRN: Everything You Wanted to Know About Salmon DNA

PDRN: everything you wanted to know about the trend that took over Korea (and no, it isn't as strange as it sounds)

If you follow the Korean beauty world, you've almost certainly heard the term "salmon DNA" or PDRN thrown around more than once lately. Kim Kardashian has declared herself a devoted fan, Bar Refaeli has shared that she tried it, and in Korea it has long since become the gold standard for achieving perfect skin. Before you wonder what fish have to do with your skincare routine, let's understand what this ingredient actually is and why it's considered a genuine revolution in aesthetics.

PDRN is short for a much longer, more scientific name, but what matters is that it refers to purified DNA fragments, usually derived from salmon milt. The choice of salmon is no accident. Science discovered that salmon DNA is remarkably similar — around ninety-five percent — to human DNA. That similarity is the secret behind the ingredient's ability to absorb into our skin ideally without provoking sensitivities, and to work at cell level to repair the skin from within.

Unlike ingredients that provide only surface-level, temporary hydration, PDRN works like a personal trainer for your cells. It signals the skin to begin a process of natural renewal and stimulates collagen and elastin production. The result is firmer skin and a softening of fine lines. Beyond that, it's considered a superstar when it comes to repairing the skin barrier. It's particularly suited to irritated, red skin or skin that has been through intensive treatments, and it helps a great deal with repairing skin texture after acne and improving overall tone to give that famous Korean glow.

It's worth reassuring you that despite the slightly off-putting name, the products themselves are a very long way from their marine origin. The extract goes through extremely rigorous purification and sterilisation processes in Korea's most advanced laboratories. The finished product is clear, entirely odourless and pleasant to the touch. It contains no proteins from the fish itself, only the refined nucleic acids, which is why it is safe to use and does not trigger allergies in most people.

The beauty of PDRN is that it suits almost everyone. It's excellent for anyone wanting to start preventative anti-aging care, it's great for tired, lacklustre skin, and it works in perfect harmony with hyaluronic acid to add plumpness and glow. These days you no longer need expensive clinic injections to enjoy these benefits. Leading Korean brands have made the ingredient accessible in everyday serums and creams that absorb easily and fit into your routine at home.

To get the most out of the product, use it at the serum stage — after cleansing and before moisturiser. With consistent use you can see a significant improvement in skin texture within just a few weeks. If you use strong actives such as retinol, PDRN can be your best friend: it helps calm the skin and support its renewal while the retinol does the hard work.

Curious which products on our site contain this ingredient? I'd be glad to recommend the right PDRN serum for your skin type.
