Conditions We Treat

Polynucleotides & Skin Boosters

At Livingstone Dermatology, we understand that your skin is a reflection of your health and well-being. We are committed to the latest advancements in dermatological science, and dedicated to providing you with quality care.

Overview

Healthy and glowing skin starts from within and sometimes, it just needs the right boost. Polynucleotides (PN) and skin boosters are advanced injectable treatments designed to rejuvenate the skin at a cellular level. Rather than simply filling or tightening, these treatments work by improving hydration, elasticity and repair from deep within the skin. 

In Singapore, where our climate and lifestyle can stress the skin, PN and skin boosters have become popular for those seeking natural and refreshed results without drastic changes or downtime.

Polynucleotides and skin boosters have become some of the most popular aesthetic treatments today, loved for their ability to rejuvenate skin naturally with minimal downtime.

What are Polynucleotides?

Polynucleotides are biocompatible molecules derived from salmon DNA, known for their powerful regenerative and healing properties. When injected into the skin, they stimulate fibroblast activity. These are the cells responsible for producing collagen, elastin and hyaluronic acid (HA). This process improves skin texture, firmness and resilience over time.

Unlike fillers, which restore lost volume, polynucleotides encourage your skin to repair and renew itself. The result is a gradual, natural-looking improvement in skin quality, achieving a brighter, smoother and more supple appearance.

What are Skin Boosters?

Skin boosters are microinjections of hyaluronic acid and nourishing ingredients that deeply hydrate the skin. Think of them as a moisture reservoir beneath your skin’s surface that functions to improve plumpness, smoothness and glow.

While topical skincare hydrates only the outermost layer, skin boosters deliver lasting hydration from within, revitalising dull and tired skin, as well as improving fine lines caused by dryness or sun exposure.

LEVEL OF SEVERITY WHAT WE USUALLY DO
Mild or intermittent eczema
  • Moisturising (emollients) – applied generously and frequently to lock in moisture and repair the skin barrier.
  • Gentle skincare – fragrance-free cleansers, short lukewarm showers and immediate moisturising after bathing.
  • Topical anti-inflammatories – mild corticosteroid creams or non-steroid alternatives (calcineurin inhibitors) for flare-ups.
  • Trigger avoidance – reducing exposure to irritants like harsh soaps, synthetic fabrics or long hot baths.
Moderate or frequent flare-ups
  • Stronger topical treatments – medium-strength corticosteroids or regular use of calcineurin inhibitors under supervision.
  • Wet wrap therapy – dressings soaked in medicated solutions or moisturiser, wrapped around affected areas to soothe and heal.
  • Treatment of infection – topical or oral antibiotics if eczema becomes crusted or oozy.
  • Phototherapy – controlled exposure to narrowband UVB light for widespread or stubborn eczema.
  • Lifestyle adjustments – personal skincare routines and flare-prevention strategies discussed during consultation.
Severe or resistant eczema
  • Systemic medications – immunosuppressants such as cyclosporine, methotrexate or azathioprine are prescribed under close monitoring.
  • Biologic therapies – advanced targeted injections like dupilumab, used when other treatments are not enough.
  • JAK inhibitors – newer oral medications for moderate-to-severe eczema, available under dermatology care.
  • Combination therapy – mixing topical, systemic and lifestyle measures to achieve long-term stability.
  • Ongoing follow-up – regular reviews to adjust treatment, monitor side effects and support quality of life.

Polynucleotides vs Skin Boosters: What is the difference?

Although both treatments aim to enhance skin quality, they work through different mechanisms. This includes:

ASPECT POLYNUCLEOTIDES SKIN BOOSTERS
Main function Stimulates tissue repair and collagen regeneration Provides deep hydration and improves elasticity
Composition Fragments of salmon DNA Hyaluronic acid-based
Results Firmer and healthier skin over time Immediate glow and hydration
Longevity Gradual results that improve over weeks to months Quicker visible results lasting several months
Best for Dull, thinning or ageing skin needing rejuvenation Dehydrated or uneven skin needing radiance

Due to their contrasting mechanisms, many patients can benefit from combining both treatments for immediate hydration and a long-lasting glow.

How do Polynucleotides and Skin Boosters work?

Both treatments are designed to enhance skin health, but they act through different biological mechanisms that complement each other.

Salmon DNA is chosen for their compatibility with human tissues. These fragments are extracted and purified to create a highly potent and effective solution. When injected into the skin, they act as biological “signals” that awaken your skin’s natural repair system.

They work through:

  • DNA repair and cell regeneration – polynucleotides stimulate fibroblast activity, which is essential for skin strength and elasticity.
  • Improved microcirculation – they enhance oxygen and nutrient delivery to the skin, promoting healing and revitalisation.
  • Anti-inflammatory and antioxidant effects – polynucleotides reduce oxidative stress and calm inflammation, helping restore the skin’s natural balance, especially after sun damage or ageing.

Meanwhile, skin boosters are primarily made of hyaluronic acid, a natural molecule found in the skin that can hold up to 1,000 times its weight in water.

When injected, hyaluronic acid acts like a moisture reservoir within the dermis, providing long-lasting hydration. It works by:

  • Enhancing lipid production and cellular cohesion.
  • Increasing water retention and skin volume.
  • Promoting a healthy and hydrated environment that reflects light evenly.

What are the benefits of Polynucleotides and Skin Boosters?

Together or individually, these treatments offer:

When to choose Polynucleotides or Skin Boosters?

benefits of hyaluronic acid.
Hyaluronic acid works like a moisture magnet, drawing water into the skin to restore deep hydration, improve elasticity and give the complexion a healthy glow.

While polynucleotides and skin boosters share similar goals, their mechanisms and outcomes differ. This includes:

  • Address long-term concerns – polynucleotides work at a cellular level, with gradual but lasting improvements in texture and resilience.
  • Improve scars or damaged skin – by supporting tissue repair, PN helps refine acne scars and uneven skin tone.
  • Regenerate and strengthen your skin structure – polynucleotides stimulate collagen and elastin production, ideal for improving firmness and elasticity.
  • Repair and calm sensitive or inflamed skin – the anti-inflammatory properties make it suitable for rosacea-prone or post-procedure skin.
  • Support overall skin healing and anti-ageing – ideal for those seeking regenerative skin therapy rather than surface hydration alone.
  • Enhance luminosity before a special event – results are visible within days, making it a popular choice for pre-event rejuvenation.
  • Improve rough or uneven texture – boosts smoothness and softens the skin’s surface for a refined, polished look.
  • Instant hydration and radiance – hyaluronic acid plumps and moisturises the skin for a quick, dewy glow.
  • Maintain healthy hydration – regular sessions help retain moisture, especially in air-conditioned environments or dry climates.
  • Soften fine lines from dryness – perfect for smoothing small creases around the mouth, eyes and forehead.

What to expect from Polynucleotides and Skin Booster treatments?

Both polynucleotides and skin boosters are gentle, in-clinic injectable treatments designed to enhance your skin’s health from within. Generally, the treatment consists of:

Our dermatologist will start with a detailed consultation to understand your skin type, goals and any existing conditions. During this visit, you will discuss which treatment best suits your concerns.

The process entails:

  • Preparation avoid alcohol, blood-thinning supplements and anti-inflammatory medications for at least 24 hours before treatment, as they can increase the risk of bruising.
  • Skin readiness you may be advised to stop active ingredients like retinoids or exfoliants for a few days beforehand to minimise irritation.
  • Comfort a topical numbing cream is usually applied before the procedure to ensure a comfortable experience.

The treatment is performed with precision and care, taking around 30 to 60 minutes depending on the areas treated.

  • Cleansing the skin is thoroughly cleansed to maintain sterility.
  • Precise microinjections using fine needles, the doctor delivers small amounts of polynucleotide or skin booster solution into the superficial layer of the skin.
  • Technique tiny microdroplets are placed evenly across the face, neck or other target areas to ensure uniform hydration and stimulation.
  • Comfort level most patients describe the sensation as mild pressure or pinpricks rather than pain, thanks to the numbing cream and delicate injection technique.

You can resume most normal activities immediately after the session, though your skin may appear slightly pink or bumpy at the injection sites for a few hours.

It is completely normal to notice:

  • Mild redness or swelling that settles within 1 to 2 days.
  • Tiny visible bumps under the skin that smooth out naturally as the solution disperses.
  • Gradual improvement in skin hydration, glow and elasticity over the following days and weeks.

Our dermatologist will provide tailored aftercare advice, but general recommendations include:

  • Avoid exfoliating acids and retinoids for 3 to 5 days to allow optimal healing.
  • Avoid touching or applying makeup for the first 12 to 24 hours.
  • Protect your skin with sunscreen and a gentle moisturiser.
  • Skip saunas, strenuous exercise and alcohol for a day or 2.
benefits of polynucleotides.
These treatments can help smooth fine lines, improve uneven tone, calm redness and revive dull or tired-looking skin.

What results can I expect?

Polynucleotides do not change the shape of your face or add volume. Instead, they revitalise your skin at a cellular level, helping it repair and restore its natural balance.

You can expect:

  • A fresher and healthier-looking complexion
  • Improved elasticity and firmness
  • Reduced redness and sensitivity
  • Smoother and more even skin tone

The effects develop progressively over several weeks as collagen and elastin production increase. Most patients describe their skin as looking well-rested and naturally radiant rather than altered or overfilled.

Skin boosters, on the other hand, deliver deep and lasting hydration by replenishing hyaluronic acid within the skin. Results are usually visible within the first week and continue to improve over the next few weeks.

You will notice:

  • A more luminous and dewy appearance
  • Fewer lines and creases
  • Improved skin texture and suppleness
  • Softer and plumper skin

Both treatments complement each other beautifully as polynucleotides strengthen and repair, while skin boosters hydrate and smooth. When combined in a tailored plan, they can help maintain long-term skin health and radiance.

How many sessions will I need?

The number of sessions varies depending on your skin condition, goals and age. Our dermatologist will recommend a personalised plan.

But generally, it looks like:

  • Initial phase usually 3 to 4 sessions spaced 2 to 4 weeks apart.
  • Maintenance every 6 to 12 months to sustain collagen renewal and skin strength.
  • Visible results gradual improvement after the first few weeks, with optimal glow and firmness around 2 to 3 months after the final session.

Polynucleotides are designed to work biologically, so results build up naturally as your skin regenerates.

  • Initial phase typically 2 to 3 sessions spaced 3 to 4 weeks apart.
  • Maintenance every 4 to 6 months, depending on your hydration levels and skin goals.
  • Visible results noticeable hydration and glow within days, with cumulative improvements over the next few weeks.

Many patients enjoy alternating polynucleotide and skin booster treatments for comprehensive rejuvenation, restoring skin structure while maintaining a luminous, hydrated finish.
