Polynucleotides

A cutting-edge injectable treatment that uses tiny fragments of purified DNA to switch on your skin's own repair and renewal processes, improving quality, firmness and radiance from within.

About

Polynucleotides are very small fragments of highly purified DNA that when injected just below the skin's surface, send signals to your own skin cells encouraging them to regenerate and behave more like younger, healthier cells. At SAM Clinic we use the Mastelli Plinest, Plinest Eye and Newest range, which also brighten, hydrate and protect the skin as part of the same process. A course of 3 sessions spaced 3–4 weeks apart is recommended, with the best results usually visible 4–8 weeks after the final session.

How It Works

1

Consultation & Assessment

A full medical and aesthetic consultation is conducted prior to any treatment to check if this treatment is suitable for you and your particular concerns.

2

Treatment

Numbing cream is used prior to treatment, which is delivered using very fine needles across the skin. Occasionally cannulas are also used.

3

Aftercare

A full aftercare plan is discussed with you and sent to you digitally for reference afterwards. This is to minimise complications and to ensure the best result for you.

Is This The Right Treatment For You?

Polynucleotides are ideal for anyone who wants to improve their skin quality in a gradual, natural way, using the skin's own biology rather than adding volume. They are particularly popular for fine lines, dullness, uneven tone and loss of firmness. Under the eye is a standout area for this treatment, as it uniquely improves hollowing and dark circles without causing any puffiness. Patients who appreciate a science-led approach and like to see skin that is genuinely healthier, not just filled, tend to love this treatment.

Frequently Asked Questions

Numbing cream is applied before all polynucleotide treatments. The injections are placed very close to the surface of the skin and most patients find the procedure comfortable with minimal discomfort. We can also use a cannula if needed.

A course of 3 sessions typically gives results that last 6 months. A maintenance session every 6 months helps to keep the improvements going, and your skin continues to benefit cumulatively with each course.

Yes. Polynucleotides have been used safely in medicine for many years and the purified DNA fragments are very well-tolerated by the body. The Mastelli range we use at SAM Clinic is CE marked to the highest standard, which means it has passed rigorous safety and quality testing.

Polynucleotides can be used on the face, neck, chest and under the eyes. Under-eye treatment is a particular speciality at SAM Clinic, as the Plinest Eye formula is specifically designed for this delicate area and works without causing puffiness.

A course of 3 sessions is £600; individual maintenance sessions are £250. Each syringe is enough to treat both under-eye areas, around a third of the face, the neck, or the full chest area.
