Polynucleotides vs. Skin Boosters: What’s the Difference and Which One Is Right for You?

When it comes to injectable skincare treatments, there’s more choice than ever before—and two of the most in-demand options right now are polynucleotides and skin boosters. At our Aesthetics Clinic in Southampton, we offer both, and while they might seem similar at first glance, they serve very different purposes.

If you’re considering one of these treatments but aren’t quite sure how they compare, this guide will help you understand exactly what each one does, what results to expect, and how to decide which is best suited to your skin.

Polynucleotides are an advanced injectable treatment that work at a cellular level to encourage the skin to repair, regenerate, and strengthen itself. Rather than simply hydrating or plumping the skin, polynucleotide treatments help your body create better-quality skin from within.

They’re made from fragments of DNA (usually derived from salmon), which are highly purified and biologically compatible with human tissue. Once injected, they stimulate fibroblast activity, boost collagen and elastin production, and have an anti-inflammatory effect—all of which contribute to firmer, clearer, more resilient skin over time.

Benefits of Polynucleotide Treatment:

• Improves skin elasticity and structure
• Stimulates collagen and elastin production
• Supports cell regeneration and tissue repair
• Reduces inflammation and oxidative stress
• Helps with scarring, pigmentation, and early signs of ageing
• Safe to use in delicate areas like under the eyes or around the mouth

This treatment is particularly effective for skin that is showing signs of fatigue, inflammation, or premature ageing. Results are progressive and best seen after a course of treatments.

Skin boosters, on the other hand, are injectable treatments designed to hydrate and improve the surface quality of the skin. Their main ingredient is hyaluronic acid (HA)—a naturally occurring molecule that retains moisture and keeps the skin plump and supple.

Rather than targeting volume like dermal fillers, skin boosters use a lighter form of HA, injected just beneath the skin to improve texture, elasticity, and glow. They don’t change the shape of the face—they simply enhance the way your skin looks and feels.

Benefits of Skin Boosters:

• Deeply hydrates and nourishes the skin
• Smooths fine lines and crepey texture
• Enhances radiance and overall glow
• Improves skin tone and elasticity
• Suitable for the face, neck, décolletage and hands
• Offers quick results with minimal downtime

Skin boosters are ideal for anyone wanting a visible refresh, whether it’s to improve dryness, prepare for an event, or maintain healthy-looking skin. At our clinic in Southampton, we use industry-leading brands Profhilo & Seventy Hyal for our treatments, giving you the peace of mind that you are receiving only the best product during your treatment.

Although both treatments involve injectable solutions designed to improve the skin, they work in very different ways. Below, we break down how they compare across several important categories:

How They Work

Polynucleotides encourage the skin to heal and regenerate by stimulating cellular activity. They repair skin at a deeper level, promoting collagen and elastin while reducing inflammation.

Skin boosters deliver hydration and nutrients directly to the skin using hyaluronic acid. They work more on the surface level to smooth, plump and brighten.

Treatment Goals

Polynucleotides are ideal for long-term skin improvement. If your concern is skin quality, elasticity, scarring, or early signs of ageing, this treatment strengthens the skin’s structure over time.

Skin boosters are ideal for quick visible results. They improve hydration, give a radiant glow, and help skin look fresher and smoother—especially when it’s feeling dull or dehydrated.

Results Timeline

Polynucleotides work gradually. Most clients begin to see changes after 2–3 treatments spaced a few weeks apart, with full results developing over several months.

Skin boosters often show noticeable improvement within a few days to a week. Many clients report better hydration and glow after the first or second treatment.

Longevity of Results

Polynucleotide treatments have longer-lasting effects because they improve the skin’s own function. Results can last several months and continue to improve with maintenance.

Skin boosters offer shorter-term results, typically lasting 3–6 months depending on the product used and your skin’s condition.

Treatment Areas

Both treatments can be used across the face, neck, décolletage, and hands—but:

Polynucleotides are especially effective in delicate areas like under the eyes, around the mouth, and in scarred or inflamed skin.

Skin boosters work best over broader areas of skin that need hydration or an overall lift in texture and glow.

Suitability for Skin Types

Polynucleotides are suitable for sensitive, inflamed, acne-prone, or ageing skin. They’re often recommended for clients who need to calm and rebuild the skin barrier.

Skin boosters are suitable for most skin types, including younger clients looking for a radiance boost or older clients wanting to maintain skin hydration and suppleness.

Ultimately, the choice between polynucleotides and skin boosters comes down to what your skin needs and what kind of results you’re looking for.

If you’re aiming for long-term skin improvement, better elasticity, and a more resilient complexion, polynucleotides are likely the better fit. If you’re looking for a quick, visible refresh with glowing, hydrated skin, skin boosters are an excellent choice.

Still unsure? That’s where we come in.

Choosing between polynucleotides and skin boosters isn’t always straightforward—especially when both offer powerful results in different ways. While skin boosters are ideal for hydrating and revitalising tired skin, polynucleotides are designed to stimulate deep regeneration and long-term skin health.

Understanding your skin’s specific needs is key. Some may benefit more from quick, visible improvements in radiance and texture, while others are looking for a solution that addresses underlying concerns such as loss of elasticity, inflammation, or scarring. In some cases, combining both treatments can offer a synergistic effect, delivering an immediate glow while supporting the skin’s deeper repair processes.

At Kaizen Medical in Southampton, our focus is always on bespoke, results-driven care. We offer both polynucleotide treatments and skin boosters as part of our tailored skin rejuvenation plans. During your consultation, we take the time to assess your skin, listen to your concerns, and guide you toward the treatment that will genuinely benefit your complexion and confidence in the long term.
