With PDRN becoming a viral skincare ingredient favoured by celebrities for its hydrating and anti-ageing properties, three beauty writers put Medik8's new formula to the test.
What is PDRN?
PDRN, or Polydeoxyribonucleotide, is traditionally derived from salmon DNA. However, Medik8's Exo-PDRN Prismatic+ serum uses a pioneering vegan PDRN with a stable tetrahedral structure, offering 100% better skin absorption than traditional PDRN. The vegan version penetrates 61% deeper, strengthening the skin barrier and promoting a healthier, more radiant complexion.
The Testers
Beauty writers Beth (20s), Eve (30s), and Laura (50s) tested the serum over several weeks. The pump bottle provides 80 uses, costing under £1 per application at £79 per bottle.
Beth's Experience
After two weeks, Beth noticed fresher skin and after four weeks, a noticeable glow and reduced redness. However, fine lines on her forehead remained unchanged. She recommends pairing with a retinal for anti-ageing.
Eve's Experience
Eve used the serum daily for three weeks. She appreciated the hydrating, dewy glow but saw minimal improvement in dark spots and expression lines. Crows feet appeared slightly smoother.
Laura's Experience
After 14 days, Laura felt her skin was smoother and fresher, though fine lines were not dramatically reduced. She found the serum lightweight and luxurious, and remains optimistic about long-term results.
Overall, the Medik8 serum offers immediate hydration and a radiant glow, with anti-ageing benefits expected to develop over continued use.
