Three beauty writers from Mirror have tested Medik8's new Exo-PDRN Prismatic+ serum, a vegan alternative to traditional salmon-derived PDRN. The serum claims to strengthen the skin barrier, boost radiance, and improve tone and texture, with results visible in as little as one week.
Medik8's formula uses a vegan PDRN with a stable tetrahedral structure, said to penetrate 61% deeper than traditional PDRN and offer 100% better absorption. The serum is designed to support skin longevity, a growing trend in 2026, alongside products from Paula's Choice and No7.
Beauty writer Beth, in her 20s, reported fresher, glower skin after two weeks, with reduced redness after four weeks, though fine lines remained unchanged. Eve, in her 30s, noted a dewy glow after three weeks but experienced some breakouts. Laura, in her 50s, found the serum hydrating and calming, with improved skin texture.
The serum comes in a pump bottle with 80 uses, priced at £79 (less than £1 per use). It absorbs quickly and layers well with other products. For a budget alternative, Boots offers a PDRN serum at £8.
While the serum is not a substitute for injectables, the writers agreed it is a worthy addition to most skincare routines, delivering noticeable improvements in hydration and radiance.
