Read the ingredient list, not the front of the pack. Look for Sodium DNA or Hydrolyzed DNA, see whether it sits before or after the preservatives, check for a UK responsible person, a batch number and a date, and ask what any ppm claim actually measures.
A fragrance-free, vegan serum using plant DNA from Artemisia capillaris, not salmon. The brand advertises 20,000 ppm (2%), yet its ingredient list puts Hydrolyzed DNA last, and the supporting studies were run by the ingredient supplier.
The three non-Korean PDRN serums UK shoppers ask about most all use vegan, plant-type PDRN, not salmon. Only The INKEY List states an amount, and none has independent published trials of the finished serum.
Realistic PDRN before-and-after results are subtle. Injection studies measured improvements in fine lines and texture 8 to 12 weeks after a course of sessions, and some gains faded by six months. Topical PDRN has far less evidence, and most of a serum's early glow is hydration.
No trials have compared PDRN and PRP head to head, so neither has been proven better. PRP uses growth factors from your own blood and has evidence for skin thickness and elasticity. PDRN, often sold as polynucleotides, uses purified salmon DNA and has evidence for skin quality and scars. PDRN products are more consistent; PRP varies with preparation and your own blood.
PDRN and hyaluronic acid do different jobs. Hyaluronic acid is a proven humectant that draws water into skin, and as an injection it adds hydration or volume. PDRN is thought to support repair and skin quality, mainly when injected. In skincare, both mainly hydrate. Many products combine them, and you do not have to choose.
