Polynucleotide (PN) and polydeoxyribonucleotide (PDRN) boosters are among the most requested regenerative injectables in clinics across the UAE and GCC. Both names appear on Korean products such as Rejuran, Juve, Regenovue PN and Elaxen PN, and both come from purified DNA fragments, usually of salmon or trout origin. The difference lies in the size of those fragments, and that changes how the product behaves in the skin.
What PDRN is
PDRN is a mixture of short DNA fragments with a relatively low molecular weight. It was first used in medicine for tissue repair and wound healing, and in aesthetics it is used to support skin regeneration. PDRN acts mainly as a biological signal: it is studied for its effect on the adenosine A2A receptor, which is linked to tissue repair, fibroblast activity and microcirculation. Because the fragments are short, PDRN solutions are thin and spread easily, which makes them suitable for mesotherapy and for combination with microneedling.
What PN is
PN uses longer DNA chains with a higher molecular weight. In a syringe this gives a more viscous gel. Besides the regenerative signal, PN binds water and forms a temporary scaffold in the dermis, so it is valued for hydration and skin quality, including thin and delicate areas. PN is also used in products made for the delicate eye area, such as Pure Eyes PN Booster.
Key differences at a glance
- Chain length: PDRN — short fragments; PN — long chains.
- Texture: PDRN — fluid; PN — viscous gel.
- Main role: PDRN — regenerative signal; PN — regeneration plus hydration and scaffold effect.
- Typical use: PDRN — mesotherapy and microneedling protocols; PN — injectable skin booster courses, including the eye area.
How clinics choose between them
The choice usually depends on the treatment goal, the area and the protocol the practitioner already uses. Many clinics keep both: a PN booster for injectable courses and a PDRN product for mesotherapy or post-procedure care. Some products combine PN or PDRN with hyaluronic acid, for example Elaxen HA-PN or Caratfill Youthful Essence (PN+HA). Always follow the manufacturer’s instructions for indications, technique and storage.
