Uses, Safety, and SuitabilityPolynucleotides Explained

Polynucleotides are part of a growing category of injectable treatments that focus on skin quality rather than shape or volume. They are often mentioned alongside terms such as biostimulation, regeneration, or dermal repair, which can make them sound complex or interchangeable with other treatments. In reality, polynucleotides have a specific role, a distinct mechanism of action, and a particular place within clinical skin health planning.

For many people researching aesthetic treatments, confusion arises from overlapping language. Treatments that hydrate, stimulate collagen, or support repair are frequently grouped together, even though they work in different ways and suit different skin concerns. Polynucleotides are not fillers and do not aim to change facial structure. They are also not simply hydration injections. Understanding these distinctions matters, particularly for those with delicate skin, early signs of ageing, or a preference for gradual, regenerative approaches.

This guide explains what polynucleotides are, how they work within the skin, and how they are used in UK aesthetic practice. It also explores suitability, safety considerations, treatment planning, and how polynucleotides compare with other commonly discussed skin boosters. The aim is to support informed decision-making, not to suggest that one treatment is right for everyone.
