Women’s Health Clinic FAQ
Can polynucleotides heal vaginal tears and scars?
Intimate polynucleotides are non-hormonal biostimulatory treatments used in some clinics for vulvovaginal tissue quality. The important first step is confirming the symptom cause, not choosing an injectable by name.
Direct answer
Polynucleotides may support tissue quality and repair signalling, but they should not be promised to heal active vaginal tears or erase scars. Recurrent splitting, painful episiotomy scars or fragile skin need assessment to identify GSM, infection, lichen sclerosus, pelvic-floor tension, scar tethering or poor wound healing. Active wounds, infection, unexplained bleeding and severe pain should be treated first. In selected healed tissue concerns, polynucleotides may be considered as an adjunct rather than a stand-alone repair solution.
Your clinician should review symptoms, medical history, allergies, medicines, cancer history where relevant, alternatives, expected benefits, limitations and aftercare before deciding whether treatment fits.

At a glance
These are the main points to understand before deciding whether intimate polynucleotides are suitable.
Polynucleotides at a glance
Non-hormonal biostimulation
Mechanism of Action
PNs activate the adenosine A2A receptor and the nucleotide salvage pathway, increasing fibroblast vitality, enhancing Collagen I and II synthesis.
Formulations
Available as injectable gels (such as NewGyn®, which combines PN-HPT® with hyaluronic acid and mannitol) or as topical vaginal ovules.
Target Conditions
Episiotomy scars, perineal tears, post-surgical adhesions, and vulvovaginal atrophy .
Key Benefits
Improves tissue elasticity, deeply hydrates the mucosa, reduces dyspareunia (painful sex), and minimises scar discomfort .
Important safety note
Fish Allergies: Because PNs are derived from highly purified salmon or trout DNA, treatment is strictly contraindicated in patients with known fish allergies .

Detailed answer
Active wounds are different
Recurrent tearing or scars need assessment before any injectable is considered.
Repair support is not scar erasure
PN can only be discussed as tissue-quality support in selected healed or fragile tissue concerns.

What it means
Post-Surgical Healing: In a study of 166 patients undergoing pelvic floor surgery with polypropylene mesh, post-operative use of PN and terpinenol ovules significantly reduced mesh exposure complication rates to 1%.
Why symptoms matter
Scar Rejuvenation: Real-world applications of PN/HA injectables demonstrate reported improvement in treating menopausal and post-surgical atrophy, significantly reducing subjective symptoms like soreness, tingling, and dyspareunia (pain during sex) .
Evidence limits
Evidence is encouraging in selected areas, but intimate-use claims should remain cautious and assessment-led.
Treatment fit
Setting: Administered as an in-clinic procedure by a trained gynaecologist or aesthetic practitioner .
What this means in practice
Setting: Administered as an in-clinic procedure by a trained gynaecologist or aesthetic practitioner .
Treatment Schedule: Clinical protocols typically involve a primary phase of 3 to 6 injection sessions, spaced 2 to 4 weeks apart (or every 15 days), depending on the severity of the scar or tissue atrophy .
Patient safety
Why diagnosis comes first
Many intimate symptoms overlap. The right treatment depends on whether the issue is GSM, infection, vulval skin disease, scarring, pelvic-floor guarding, medication effect or another cause.
It checks the cause
Post-Surgical Healing: In a study of 166 patients undergoing pelvic floor surgery with polypropylene mesh, post-operative use of PN and terpinenol ovules significantly reduced.
It protects safety
Fish Allergies: Because PNs are derived from highly purified salmon or trout DNA, treatment is strictly contraindicated in patients with known fish allergies .
It reviews alternatives
Moisturisers, lubricants, local ooestrogen, pelvic-floor care or specialist review may be more appropriate first.
It sets expectations
Polynucleotides are gradual tissue-support treatments, not instant resolves or promised outcomes.
Non-hormonal does not mean automatic
A hormone-free option may still be unsuitable if there is infection, unexplained bleeding, pregnancy, recent surgery, severe fish allergy or unclear pelvic pain.
Good care explains product source, treatment route, alternatives, limits, aftercare and when another medical pathway is safer.
Considerations
What to consider
Treatment planning should include diagnosis, symptom pattern, allergy risk, medicines, consent, realistic timelines and aftercare.
Consultation priorities
A consultation should review symptoms, medical history, fish allergy, infection risk, bleeding risk, pregnancy status, expectations and alternatives.
Consent
Aftercare
Review
Before treatment
Preparation: Patients must discontinue blood-thinning medications (e.g., aspirin or NSAIDs) at least 7 days before treatment and ensure the area is free from active infection .
During care
The Procedure: Using a fine needle, the practitioner delivers the PN gel via micro-injections directly into the dermal and submucosal layers of the scarred or atrophic tissue .
Aftercare
Immediate Aftercare: Patients are instructed to avoid sexual intercourse, strenuous exercise (gym), hot baths, saunas, and tampons for 24 to 72 hours to prevent friction and infection .
When to reassess
If symptoms persist, worsen or do not match expectations, reassessment is safer than repeating treatment automatically.
Practical expectations
Treatment Schedule: Clinical protocols typically involve a primary phase of 3 to 6 injection sessions, spaced 2 to 4 weeks apart (or every 15 days), depending on the severity of.
Costs and treatment plans should be confirmed before booking; do not rely on generic package claims.
Common concerns and myths
Common misconceptions
Clear patient information should correct over-simple claims and keep expectations realistic.
Myth: polynucleotides are fillers
Reality: they are biostimulatory DNA fragments used for gradual tissue-quality support, not instant volume.
Myth: hormone-free means suitable for everyone
Reality: fish allergy, infection, bleeding, pregnancy, recent surgery and unclear pain can make treatment unsuitable.
Myth: results are promised
Reality: response varies and should be reviewed before repeating treatment.
Evidence and limits
Mechanism-of-action language should not be treated as proof of a predictable result.
Alternatives still matter
Moisturisers, local hormonal care, pelvic-floor physiotherapy, infection treatment or specialist review may be better for some patients.
Safety checklist
Safety checklist
Use these questions to decide whether treatment should be discussed, delayed or redirected.
Has the cause been assessed?
Symptoms should be reviewed in context before selecting an injectable treatment.
Are red flags absent?
Active infection, unexplained bleeding, severe pain or new vulval changes should be checked first.
Are alternatives clear?
Ask what conservative, hormonal, pelvic-floor or specialist options may be more appropriate.
Is follow-up planned?
The clinic should explain aftercare, review timing and when to seek help.
Reassuring signs
Proceeding is more reasonable when diagnosis is clear, goals are realistic, red flags are absent and aftercare is understood.
No red flags
Review plan
Reasons to pause
Pause treatment for active infection, unexplained bleeding, pregnancy, severe fish allergy, recent pelvic surgery, severe pain or changing vulval skin.
Bleeding
Infection
When to escalate
When to seek medical help
Some symptoms should be assessed before any elective intimate treatment. Use NHS 111 online
Allergy symptoms
Swelling of the lips, tongue or face, breathing difficulty, widespread hives, faintness or collapse needs urgent help.
Bleeding or new skin change
New post-menopausal bleeding, ulcers, changing white plaques, unusual discharge or visible blood in urine should be assessed.
Infection signs
Fever, pus, spreading redness, worsening swelling or feeling unwell after a procedure needs prompt advice.
Emergency symptoms
Call 999 in a life-threatening emergency, including collapse, chest pain or breathing difficulty.
