Polynucleotide Treatments for Acne Scars: Can They Help Heal Your Skin?

Acne scars can leave a lasting impression long after breakouts have cleared. Whether you’ve struggled with spots in your teens or more recently as an adult, those lingering marks can chip away at your confidence and feel frustratingly difficult to treat. At Kaizen Medical in Southampton, we’re seeing an increasing number of clients asking whether Polynucleotides could be the answer to smoother, healthier-looking skin.

So, what exactly are polynucleotides, and can they genuinely help reduce acne scarring? This blog explores how the treatment works, who it’s best suited for, and what kind of results you can expect, all backed by the latest research and our clinical experience.

Polynucleotides are purified DNA fragments, typically derived from fish sources, that are used to stimulate your skin’s natural regeneration process. Unlike Dermal Fillers, which provide immediate volume, polynucleotide injections work more gradually by improving the skin’s internal structure over time. They attract hydration, support collagen and elastin production, and reduce inflammation, all key to repairing and strengthening scarred skin.

If you’re curious about the science behind these injectables, our blog about Polynucleotides for Skin Repair goes into more depth about how these molecules support tissue regeneration from the inside out.

Acne scarring, especially the indented types like rolling or boxcar scars, results from damage to collagen during inflammation. Polynucleotides encourage the body to rebuild lost collagen in these areas, gradually helping to “fill in” the scar tissue from below. This creates a more even skin texture without the need for aggressive treatments like lasers or chemical peels.

In addition to stimulating collagen, polynucleotides also support better blood flow and reduce lingering inflammation in the skin, both of which are important for long-term healing. Over time, clients often notice that their skin not only looks smoother but also feels stronger and healthier overall.

At Kaizen Medical, your treatment begins with a personalised consultation. One of our experienced practitioners will take time to understand your skin type, the nature of your acne scars, and your goals. This helps us build a tailored plan that may include polynucleotides alone or in combination with other skin treatments.

The procedure itself is quick and minimally uncomfortable. We apply a topical numbing cream beforehand, and the injections are administered either with a fine needle or cannula depending on the area and the severity of the scarring. Most clients describe the treatment as very manageable.

You’ll typically need a course of three sessions spaced three to four weeks apart, with results becoming more noticeable after the second session. If you’d like a broader overview of treatment planning and how often appointments are needed, you might find our blog How Many Sessions Will I Need? helpful.

Polynucleotide treatments require little to no downtime. Some people experience mild redness or swelling in the treated areas, which usually settles within 24 to 48 hours. Small bumps at the injection sites may appear but tend to resolve quickly. Most clients feel comfortable returning to work or social events the next day.

That said, good aftercare is essential to support healing and ensure the best possible results. For a full breakdown of what to do (and what to avoid) after your session, we recommend reading our Chronological Aftercare Guide for Polynucleotides.

Polynucleotides are especially suitable for people with shallow to moderate atrophic acne scars, particularly those with rolling or boxcar scarring. If you have more sensitive or reactive skin, or you’re concerned about the downtime and risks associated with laser treatments, Polynucleotides can be a gentler alternative. The treatment is also suitable for clients with darker skin tones who may be more prone to pigmentation changes with harsher procedures.

For clients who are still comparing options, our blog Polynucleotides vs Skin Boosters explores how these treatments differ and how to decide which might be right for your skin needs.

One of the great advantages of polynucleotide injections is that they can be safely combined with other skin treatments to enhance results. For example, combining polynucleotide treatments with microneedling can accelerate collagen production and further improve skin texture. Similarly, using Polynucleotides alongside gentle laser treatments or chemical peels can help reduce downtime and promote faster healing.

If you’re interested in combination treatments, we’ll discuss your options in detail during your consultation and create a phased plan that works for your skin and schedule.

It’s important to know that Polynucleotides don’t deliver instant results, but they do deliver meaningful change. Most people begin to notice improvements in skin texture, tone, and hydration after four to six weeks, with optimal results developing around the three-month mark. These improvements tend to be long-lasting, with many clients choosing to return once or twice a year for maintenance sessions.

Because results are based on your body’s natural collagen production, they often appear more subtle and natural than other injectable treatments, and they continue to improve the overall quality of your skin.

At Kaizen Medical, we pride ourselves on providing treatments that are not only effective but also rooted in medical expertise and safety. All our injectable procedures are carried out by experienced practitioners who take time to understand your skin and create a bespoke plan that fits your needs. We follow the latest clinical evidence and safety protocols, ensuring every treatment is tailored, precise, and results-driven.

Whether you’re new to aesthetic treatments or have tried other options in the past, we aim to offer honest advice and long-term skin solutions, not quick fixes.
