Polynucleotides

Derived from purified DNA fragments, they are used in aesthetic medicine to improve overall skin quality rather than simply adding volume.

Once injected into the skin, polynucleotides are thought to support the skin’s natural regenerative processes and stimulate activity within the tissue. They can help improve hydration, elasticity and skin texture, creating a fresher, healthier-looking appearance over time.

Polynucleotide treatments are particularly suited to areas where the skin may appear dull, dehydrated, thin or lacking in elasticity. They can be used on the face, neck and hands, depending on the product selected and your individual needs.

At SG Aesthetics, we use PolyPhil™, an injectable polynucleotide treatment designed to support skin regeneration and improve skin quality. The polynucleotides used in PolyPhil™ are sourced from European freshwater fish intended for human consumption and undergo a purification process known as Polynucleotide High Purification Technology (PN-HPT).

PolyPhil™ treatments can help improve skin hydration, elasticity, texture and tone. They are not designed to change your facial features or add significant volume; instead, the aim is to improve the quality and appearance of the skin gradually, supporting a natural-looking result.

At SG Aesthetics, treatments are tailored to your skin and your desired outcome. Sarah’s extensive experience in aesthetic practice, combined with her clinical training and Master’s degree in Professional Non-Surgical Aesthetic Practice, allows her to take a considered approach to treatment and select the most appropriate option for each individual.

PolyPhil™ Eye is specifically formulated for the delicate skin around the eyes. It is designed to support skin quality in this sensitive area and improve the appearance of tired-looking eyes, helping the eye area to appear fresher and more revitalised.

A course of 2–3 treatments is usually recommended, although some improvement may be noticeable after a single session. Results develop gradually and the duration of effects varies between individuals.

A next-generation skin booster combining polynucleotides with non-cross-linked hyaluronic acid to improve hydration, elasticity, firmness and overall skin quality.

A course of 3 treatments, typically 3 weeks apart, is recommended, with the exact treatment plan tailored to your skin and individual needs.
