Clients who choose advanced skin treatments want more than a mild refresh. They expect real change in texture, firmness and luminosity. The 5ml Polynucleotide Skin Booster in Croydon at Posh Skin Clinic has been designed for those higher expectations.

Polynucleotides are injectable biostimulators that support tissue repair, hydration and collagen production. Many clinics in the UK use smaller 2ml doses as a standard protocol. At Posh Skin Clinic, we offer a 5ml high dose approach for suitable candidates, with the aim of delivering deeper, longer lasting rejuvenation, especially for ageing or stressed skin.

This guide explains how polynucleotides work, compares 5ml vs 2ml protocols and shows where a high dose sits alongside treatments such as Profhilo skin booster, microneedling  and HydroFacial Plus in a personalised treatment plan.

 

What are polynucleotide skin boosters?

Polynucleotide boosters use highly purified DNA fragments, often derived from salmon, to create a more supportive environment for skin cells. Once injected, these fragments attract water, improve tissue oxygenation and encourage fibroblasts to produce fresh collagen and elastin.

Clients usually report:

• Better overall hydration

• Smoother, more even texture

• Softening of fine lines and early creasing

• Fresher, “rested” looking skin

The effect is subtle and progressive, which makes polynucleotides ideal for those who want a natural result rather than an obvious change in facial structure.

At Posh Skin Clinic, we use polynucleotides as a targeted biostimulatory treatment and also integrate them into wider plans with dermal fillers, anti wrinkle injections  and advanced facials when appropriate.

5ml vs 2ml Polynucleotide Skin Booster: why dose matters

 

Many protocols on the market use 2ml per session as a standard dose. This can provide a gentle improvement, particularly in younger skin or as maintenance. However, clients with visible ageing, laxity, or textural damage often benefit from a more intensive approach.

The 5ml Polynucleotide Skin Booster in Croydon offers:

• Wider treatment coverage
  A 5ml dose allows your practitioner to treat larger areas in a single session, such as full face and key parts of the neck, rather than focusing on small zones only.

• Stronger biostimulation
  A higher volume increases exposure of the tissue to active polynucleotides, which may support more robust collagen and elastin production over time.

• More noticeable hydration and “glow”
  Clients who receive 5ml frequently describe a clearer, fresher skin quality compared with lighter protocols.

• Fewer sessions in a course
  Because each session carries more product, suitable clients may require fewer visits to achieve their initial result, which can be more convenient in busy schedules.

Of course, dose is never chosen in isolation. Your practitioner considers age, skin condition, medical history and treatment goals before recommending either a 2ml or 5ml plan.

Who is the 5ml Polynucleotide Skin Booster best suited for?

The high dose option is particularly useful for:

• Men and women with visible signs of ageing, including fine lines, dullness, or early sagging

• Skin that has lost bounce following weight loss, stress, or illness

• Clients who want stronger rejuvenation without changing their facial structure

• Those preparing for a big life event, where more obvious improvement is needed within a set timeframe

Clients in their thirties may use 5ml as a powerful “reset” after sun exposure or lifestyle stress. Clients in their forties, fifties and beyond often choose it as part of a long term strategy to keep skin looking fresh, supported and hydrated.

If skin is very fragile or there are specific concerns such as acne scarring, your practitioner may combine polynucleotides with Fractional RF Microneedling to support both surface renewal and deeper repair.

How the 5ml treatment works at Posh Skin Clinic

Every treatment at Posh Skin Clinic in Croydon starts with a detailed consultation. During this appointment we assess:

• Current skin texture, colour and elasticity

• Volume distribution and facial proportions

• Previous treatments or skincare routines

• Medical history, including allergies and medications

If a 5ml Polynucleotide Skin Booster in Croydon is suitable, a tailored plan is created. In practice, this usually looks like:

1. Preparation
   Skin is cleansed carefully. A topical numbing cream can be applied to make the procedure more comfortable.

2. Injection mapping
   Your practitioner plans specific injection points for even coverage. Common areas include cheeks, lower face, jawline and sometimes upper neck.

3. Precise microinjections
   The product is placed into the superficial layers of the skin using very fine needles or cannulas. Small blebs flatten as the product disperses.

4. Aftercare
   Mild redness or small bumps can appear for a short time. Most clients return to normal activity the same day. Simple aftercare advice is provided, alongside guidance on skincare products.

5. Follow up
   Results gradually appear over several weeks. Further sessions may be scheduled, often three to four weeks apart, depending on the starting point and goals.

Comparing 5ml Polynucleotides with Profhilo and other boosters

Clients often ask how high dose polynucleotides compare with Profhilo, Salmon DNA boosters and other biostimulatory options.

Polynucleotides vs Profhilo

• Polynucleotides (5ml) focus on tissue repair, hydration and improving the extracellular matrix. They are particularly helpful for texture, resilience and overall skin health.

• Profhilo is a high concentration hyaluronic acid treatment that spreads within the tissue to improve firmness and hydration. It is excellent for skin laxity and fine lines, particularly on the lower face and neck.

Many Croydon clients use both, spaced appropriately, to support different aspects of skin quality. Polynucleotides strengthen and repair, while Profhilo improves firmness and glow.

Polynucleotides within a wider plan

A high dose polynucleotide treatment can work alongside:

• HydroFacial Plus for deep cleansing and exfoliation
• Microneedling or Fractional RF Microneedling for collagen stimulation at different depths
• Anti wrinkle injections to relax expression lines
• Dermal fillers to support structure where needed

This layered approach gives a more “360 degree” result compared with relying on one treatment alone.

Expected results and treatment timeline

Results from a 5ml Polynucleotide Skin Booster in Croydon build gradually. Most clients notice:

• Softer texture and improved hydration within the first few weeks

• Healthier looking skin tone with less dullness

• Subtle softening of fine lines around eyes, cheeks and mouth

• A more elastic, “springy” feel to the skin over time

A typical course might include two to three high dose sessions, spaced three to four weeks apart, followed by maintenance sessions a few times per year. The exact schedule is personalised.

Lifestyle also plays a role. Good skincare, sun protection and healthy habits will support and maintain your results.

Is a high dose polynucleotide booster right for you?

Not every client requires a 5ml protocol. Some may prefer or need a lighter 2ml course, especially if they are younger, new to injectable treatments, or focusing on a small facial area.

A high dose approach may suit you if:

• You feel that topical products and light facials no longer give enough improvement

• You want stronger rejuvenation without changing facial features

• You are happy to invest in a more advanced protocol for noticeable change

• You would like a plan that can be combined with other treatments for long term results

During consultation, your practitioner will explain both 2ml and 5ml options, discuss investment and suggest the most appropriate route for your skin.
