Polynucleotide (PNHPT) & Exosome Regenerative Injections

NU.U Aesthetics & Wellness offers a suite of regenerative injection therapies — including polynucleotide (PNHPT) treatments and exosome-based biologics — that harness the body's own biological signalling pathways to restore skin quality from within. These treatments represent the clinic's regenerative aesthetics philosophy: lasting improvement through biological stimulation rather than surface-level masking.

Polynucleotide treatments (branded as Rejuran, Plinest, or PNHPT) involve injecting DNA fragments derived from natural sources into the dermis. These polynucleotide chains act as biological scaffolds that stimulate fibroblast activity, boosting collagen and elastin synthesis while also providing anti-inflammatory and hydrating benefits. The result is a progressive improvement in skin density, elasticity, and hydration — typically becoming visible over…

Exosome therapy at NU.U uses extracellular vesicles derived from stem cell sources to deliver concentrated growth factors and signalling proteins directly into the skin. These microscopic vesicles activate the skin's own regenerative processes — promoting cellular turnover, collagen production, and tissue repair. Exosome treatments are particularly valued for their ability to improve skin tone, texture, and radiance, and they are often combined with laser…
