Women’s Health Clinic FAQ
Can polynucleotides treat Vulvar Lichen Sclerosus?
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 should not be presented as a primary treatment or definitive treatment for vulvar lichen sclerosus. Lichen sclerosus is a chronic vulval skin condition that needs diagnosis, follow-up and established medical treatment, usually with an ultra-potent topical steroid plan. Polynucleotides may only be discussed, if at all, as an adjunct for selected tissue-quality concerns after specialist assessment. New plaques, ulcers, bleeding, architectural change or non-response to treatment need medical review.
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
Origin
Formulated from highly purified DNA fragments derived from salmon or trout spermatozoa.
Mechanism of Action
Activates fibroblasts to stimulate collagen and elastin production, promotes angiogenesis, and reduces inflammation via purinergic receptor pathways.
Primary Benefits
Effectively reduces vaginal dryness, chronic itching, irritation, and dyspareunia (painful sexual intercourse).
Key point 4
Suitability must be confirmed after consultation and assessment.
Important safety note
Safety Profile: PNs possess a high safety and biocompatibility profile due to rigorous purification processes that eliminate allergenic proteins.

Detailed answer
LS requires medical management
Lichen sclerosus needs diagnosis, steroid treatment where appropriate and long-term surveillance.
Do not replace LS care
PN should be framed, if mentioned, as a possible adjunct after specialist review, not LS treatment.

What it means
Disease Management, Not a definitive treatment: VLS is a chronic, progressive condition requiring lifelong monitoring.
Why symptoms matter
PN therapy effectively manages symptoms and repairs tissue but does not definitive treatment the underlying autoimmune disease.
Evidence limits
Evidence is encouraging in selected areas, but intimate-use claims should remain cautious and assessment-led.
Treatment fit
Administration: Delivered via superficial intradermal and mucosal lamina propria micro-injections.
What this means in practice
Administration: Delivered via superficial intradermal and mucosal lamina propria micro-injections.
Treatment Course: A standard clinical protocol involves a series of 5 injection sessions spaced 15 to 21 days apart.
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
Disease Management, Not a definitive treatment: VLS is a chronic, progressive condition requiring lifelong monitoring.
It protects safety
Safety Profile: PNs possess a high safety and biocompatibility profile due to rigorous purification processes that eliminate allergenic proteins.
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
Initial Consultation: A comprehensive medical assessment to confirm the VLS diagnosis, rule out any contraindications (like fish allergies), and establish realistic treatment goals.
During care
The Procedure: Following the application of numbing cream, the clinician administers multiple precise tiny injections across the affected vulvar and vestibular areas.
Aftercare
Aftercare: Patients are generally advised to practice pelvic rest, avoid sexual intercourse, tight clothing, and hot baths for a few days to facilitate optimal tissue integration and healing.
When to reassess
If symptoms persist, worsen or do not match expectations, reassessment is safer than repeating treatment automatically.
Practical expectations
Treatment Course: A standard clinical protocol involves a series of 5 injection sessions spaced 15 to 21 days apart.
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: PN treats LS itself
Reality: LS needs diagnosis, surveillance and established medical management.
Myth: regenerative care replaces steroid ointment
Reality: steroid treatment remains central for many patients with LS.
Myth: white plaques are cosmetic
Reality: changing vulval skin should be medically assessed.
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.

Next step
Book a clinical consultation
A consultation can confirm whether intimate polynucleotides may be suitable, whether another pathway should come first, and what realistic outcomes, risks and aftercare would look like.
