PDRN (polynucleotide) is a biotech active widely used in Korean beauty institutes.
Marine in origin — a salmon DNA fragment — it is dosed at 500 ppm in ExoBlanc, and the dosage is printed on the sachet. Twenty minutes under a soaked sheet is an exposure no leave-on texture can offer: on removal, the skin is plumped with water, the texture refined, the jawline more defined.
Combined with Rosa Damascena Exosomes 500 ppm and KFDA Adenosine, it forms the range's most concentrated trio: denser skin, refined texture, a sharper jawline.
