Restore radiance, smooth fine lines, and deeply rejuvenate your complexion with Polynucleotides at our Harley Street clinic in Marylebone.
Polynucleotides are naturally derived, purified DNA molecules that trigger the body’s own cell renewal and tissue repair processes. When injected into the skin, they act as powerful bio-stimulators, encouraging fibroblasts to produce new collagen, elastin, and hyaluronic acid, while improving oxygenation and hydration.
Unlike treatments that mask imperfections, Polynucleotides promote true skin regeneration, delivering natural-looking, long-term improvements in tone, texture, and resilience. It’s the definition of undetectable rejuvenation.
This results in stronger, firmer, and more luminous skin over time. They’re suitable for all skin types and ages, making them a versatile solution for early signs of ageing or general skin revitalisation.
Polynucleotides work by creating a rejuvenating microenvironment within the skin. Once injected, they stimulate fibroblast activity which is the key cells responsible for producing structural proteins like collagen and elastin.
The results:
As Polynucleotides regenerate rather than fill, the outcome is a gradual, authentic improvement rather than a sudden or “overdone” change.
The under-eye area is one of the most delicate parts of the face, prone to thin skin, fine lines, and dark shadows. Polynucleotides under eyes are one of the most sought-after treatments at our Harley Street clinic, helping to:

A course of two treatments is recommended for optimal results.
