What Are Polynucleotides and How Do They Work for Skin?

Published

on

what are polynucleotides

If you’ve been exploring advanced skin treatments, chances are you’ve come across the term polynucleotides. Whether you’re a healthcare professional, a skincare enthusiast, or someone considering treatments for anti-aging or skin rejuvenation, understanding what polynucleotides are and how they work is essential.

In this guide, we’ll break down the science, benefits, safety, and practical uses of polynucleotides in aesthetic medicine, giving you clear, expert-backed insights without unnecessary jargon.

What Are Polynucleotides?

Polynucleotides are natural biopolymers made from DNA fragments, often derived from fish sources such as salmon. In skincare and aesthetics, they are used as injectable treatments to:

  • Stimulate skin regeneration
  • Boost collagen production
  • Improve hydration and elasticity
  • Support wound healing and repair

In simple terms, polynucleotides are designed to restore and repair skin from within rather than just filling lines or masking imperfections.

How Do Polynucleotides Work for Skin Rejuvenation?

Polynucleotide injections deliver DNA fragments into the skin. These fragments act as bio-stimulators, triggering natural repair processes.

Key mechanisms include:

  • Collagen stimulation: Enhances skin firmness and elasticity.
  • Antioxidant activity: Reduces oxidative stress and slows aging.
  • Hydration boost: Improves the skin’s water retention capacity.
  • Cell repair: Supports regeneration of damaged tissues.

Benefits of Polynucleotides for Anti-Aging and Skin Health

Polynucleotides are gaining popularity in aesthetic medicine because they go beyond temporary results.

Key benefits include:

  • Softer fine lines and wrinkles
  • Improved skin tone and brightness
  • Enhanced elasticity and firmness
  • Long-lasting hydration
  • Reduced acne scars and skin damage
  • Natural-looking results

Polynucleotides vs Fillers: What’s the Difference?

While both dermal fillers and polynucleotides are injectable treatments, their goals are very different.

FeatureDermal FillersPolynucleotides
PurposeAdd volume / reshapeStimulate natural repair
Duration6–18 monthsProgressive, long-term improvements
CompositionHyaluronic acid or similarDNA-based bio-stimulants
EffectImmediate plumpingGradual regeneration
Natural lookCan look artificial if overdoneSubtle, natural repair

For patients who want regeneration rather than volume, polynucleotides are often preferred.

Safety: Are Polynucleotide Injections Safe?

Polynucleotide therapy is considered safe when performed by trained professionals. Reported side effects are usually mild and temporary, including redness, swelling, or small bruises at injection sites.

Clinical note: Studies in Dermatologic Therapy (2021) highlight that polynucleotides have an excellent safety profile with minimal risks of allergic reactions, especially compared to some synthetic treatments.

PN vs PDRN Treatments: What’s the Difference?

You may also hear about PDRN (Polydeoxyribonucleotide). Both PN and PDRN are DNA-derived therapies, but:

  • PN: Longer DNA fragments, often used for broader rejuvenation.
  • PDRN: Smaller DNA fragments, commonly used for healing and regeneration.

Clinics often combine them depending on treatment goals.

How Long Do Polynucleotide Results Last?

Results typically build up gradually over 3–6 weeks after treatment and may last 6–12 months, depending on lifestyle, age, and skin condition.

Patients often undergo a series of treatments for optimal results, followed by maintenance sessions.

Cost of Polynucleotide Injections

Prices vary by region and clinic. On average:

  • UK: £250–£400 per session
  • US: $300–$600 per session

Treatment packages (3–4 sessions) are often recommended for lasting results.

Polynucleotides in Aesthetic Medicine: Who Are They For?

These treatments are suitable for:

  • Patients with early signs of aging
  • Individuals with acne scars or sun damage
  • Men and women seeking hydrated, firmer skin
  • Those wanting a natural, regenerative option instead of fillers

What Causes Black Mould and How to Stop It at Home

Published

on

what causes black mould

If you’ve ever noticed dark, musty patches creeping along your bathroom ceiling, around your window frames, or in a damp corner of your home, you’ve likely asked yourself: what causes black mould?

For homeowners, tenants, landlords, and property managers, black mould is more than an unsightly nuisance. It signals underlying issues such as poor ventilation, damp, or hidden leaks. For health-conscious individuals, black mould exposure raises serious concerns about asthma, allergies, and long-term respiratory problems. Even real estate buyers and sellers must pay attention, as mould infestations can impact property value and negotiations.

This article breaks down the causes of mould in house environments, explains the risks, and offers practical mould prevention tips. It’s written with input from building science, medical research, and trusted property care experts, so you can feel confident in the solutions.

Understanding Black Mould and Why It Matters

What Is Black Mould?

Black mould, commonly referring to Stachybotrys chartarum, thrives in moist, humid environments. While not all dark mould is toxic black mould, it often grows in damp areas and can release spores that affect both indoor air quality and human health.

Signs of Mould Infestation

  • Persistent musty smell
  • Dark spots or streaks on walls, ceilings, and corners
  • Peeling paint or wallpaper
  • Increased allergy or asthma symptoms indoors
  • Damp or clammy feel in rooms

The Main Causes of Black Mould

Damp and Condensation Problems

Condensation is one of the biggest causes of mould in house environments. When warm indoor air meets cold surfaces, water droplets form. Without proper ventilation, these damp conditions create the perfect breeding ground for mould spores.

Examples:

  • Condensation on bedroom windows in winter
  • Moisture on bathroom tiles after showers
  • Damp corners in basements

Poor Ventilation and Airflow

So, how does poor ventilation cause black mould? Rooms with limited airflow trap moisture, allowing humidity levels to rise. Bathrooms, kitchens, and laundry rooms are especially at risk when extractor fans are missing or underused.

Quick Fix: Open windows regularly, run extractor fans during and after cooking or showering, and consider whole-house ventilation systems.

Leaks and Water Damage

Yes, leaking roofs can cause black mould, as can leaking pipes behind walls or under floors. When water enters a hidden space, it often goes unnoticed until mould infestation is well-established.

Common Sources of Water Damage:

  • Roof leaks after storms
  • Cracked gutters and downspouts
  • Burst or leaking pipes
  • Faulty seals around showers, baths, or sinks

Household Moisture and Humidity

Does high humidity cause black mould in bedrooms? Absolutely. Mould thrives in relative humidity above 60%. Warm, damp environments—like bedrooms with poor airflow—become hotspots for mould spores in homes.

Solutions:

  • Use a dehumidifier
  • Insulate cold walls and windows
  • Ensure adequate ventilation

Building Materials and Construction Issues

What building materials are most prone to black mould? Porous materials such as drywall, wood, insulation, and carpets absorb water easily. Once moisture seeps in, they provide an ideal environment for mould growth.

Heating and Temperature Fluctuations

Does central heating prevent mould growth? Not necessarily. While consistent heating helps reduce condensation, uneven heating—such as warming one room while leaving others cold—can create damp conditions that fuel mould.

Windows, Doors, and Cold Bridges

Ever wondered why black mould grows around windows? Window frames and cold corners are natural condensation points. When moisture lingers, mould develops quickly.

Black Mould Health Risks

According to the UK National Health Service (NHS), exposure to mould can cause or worsen:

  • Asthma attacks
  • Allergic reactions (sneezing, runny nose, itchy eyes)
  • Respiratory infections
  • Skin irritation

The U.S. Environmental Protection Agency (EPA) also warns that long-term exposure to toxic black mould (Stachybotrys) may cause chronic coughing, fatigue, and, in rare cases, more severe health effects.

Children, the elderly, and pets are especially vulnerable, raising the question: why is black mould dangerous for children and pets? Their developing or weakened immune systems make them more susceptible to mould-related illnesses.

How to Identify the Cause of Black Mould in Your Home

LocationLikely CauseSigns to Look For
BathroomPoor ventilation & condensationMould on tiles, ceilings, grout
BedroomHigh humidity, cold wallsMould around windows, damp smells
KitchenSteam from cooking, leaksMould near sinks or extractor fans
BasementRising damp or external leaksDamp walls, musty odour
Attic / Roof SpaceLeaking roofs, poor insulationDark patches on rafters or insulation
Behind WallsHidden pipe leaks, trapped moistureStains, bulging paint, mould odour

Mould Prevention Tips for Every Home

  • Keep indoor humidity between 40–60%
  • Repair leaks promptly
  • Use extractor fans in kitchens and bathrooms
  • Insulate cold surfaces to reduce condensation
  • Clean and dry water-damaged areas within 48 hours
  • Use mould-resistant paints in damp-prone rooms

Can dehumidifiers prevent black mould from forming? Yes, when used consistently, they help maintain ideal humidity levels and reduce the risk of infestation.

Black Mould vs. Mildew: Key Differences

What’s the difference between black mould and mildew?

FeatureBlack MouldMildew
ColourDark green/blackWhite or light grey
TextureSlimy or fuzzyPowdery or fluffy
Growth SpeedSlower, but more persistentFaster, easier to clean
Risk LevelHigher health risksLower health risks

FAQs

What causes black mould in bathrooms?
Excess moisture, steam, and poor ventilation allow mould to thrive on tiles and ceilings.

How does poor ventilation cause black mould?
It traps humid air, raising moisture levels that promote mould growth.

Does central heating prevent mould growth?
Not entirely—consistent heating helps, but dampness and poor airflow can still cause mould.

Can leaking roofs cause black mould?
Yes, roof leaks create hidden damp areas where black mould quickly develops.

What health problems are linked to black mould exposure?
It can trigger allergies, asthma, respiratory infections, and skin irritation.

How to stop black mould coming back after cleaning?
Fix the underlying moisture problem, improve ventilation, and keep humidity below 60%.

Conclusion

Black mould is more than just an eyesore—it’s a clear warning sign of hidden damp, leaks, or poor ventilation in your home. By understanding what causes black mould and addressing the root problems, you can protect your property, safeguard your health, and prevent it from coming back. A dry, well-ventilated home is the best defence against mould.
