How polynucleotides signal cellular repair
Intimate polynucleotides are non-hormonal biostimulatory treatments used in some clinics for vulvovaginal tissue quality. The key decision is whether the symptom has been properly assessed first.
Direct answer
Polynucleotides signal repair by supplying nucleotide fragments that local cells can use in repair pathways, while also interacting with adenosine-linked signalling that may influence fibroblast activity, collagen, elastin, microcirculation and inflammation. Put simply, they aim to encourage tissue-quality repair rather than fill tissue with volume. The clinical value depends on correct diagnosis, product choice, injection technique and realistic expectations.
The safest plan starts by clarifying the symptom, checking red flags, explaining alternatives and agreeing realistic expectations before any procedure is booked.

At a glance
These are the main points to understand before deciding whether this option is suitable.
Polynucleotides at a glance
Non-hormonal biostimulation
**Material
** Highly purified, biocompatible DNA fragments, typically extracted from the gonads of salmon or trout.
**Mechanism
** Functions as a biological signaling molecule and biostimulator rather than a traditional volumizing dermal filler.
**Formulations
** Available as daily vaginal ovules or professional intradermal injectables (often combined with hyaluronic acid and mannitol for extended hydration).
**Primary Indication
** Reversing Genitourinary Syndrome of Menopause (GSM) and Vulvovaginal Atrophy (VVA), particularly for women seeking non-hormonal treatment.
Important safety note
**General Safety:** Highly biocompatible due to the extensive purification process that removes proteins and immunogenic matter, making allergic reactions extremely rare.

Detailed answer
How polynucleotides fit into intimate care
Polynucleotides are best explained as biostimulatory DNA fragments rather than fillers. The clinical question is whether they match the diagnosis, tissue findings and safety profile.
Not a standard filler
The aim is gradual tissue-quality support through repair signalling, hydration and extracellular-matrix activity, not instant volume or a promised sexual-function outcome.

What it means
**Symptom Resolution:** Clinical trials demonstrate profound reductions in vaginal dryness, dyspareunia (painful sex), itching, and burning.
Why it happens
**Objective Tissue Improvement:** Treatment may improve the Vaginal Health Index (VHI) by restoring a healthy, acidic pH, increasing natural secretions, and reversing mucosal thinning and petechiae.
Evidence limits
**Non-Hormonal Alternative:** potentially useful for post-menopausal women and breast cancer survivors who have strict contraindications to systemic or localised ooestrogen therapies.
Treatment fit
**Administration:** Delivered via micro-injections directly into the vulvar skin dermis and mucosal lamina propria, or self-administered as topical ovules.
What this means in practice
**Administration:** Delivered via micro-injections directly into the vulvar skin dermis and mucosal lamina propria, or self-administered as topical ovules.
**Vaginal Ovules:** Daily intravaginal insertion for 2 to 4 weeks yields rapid, measurable improvements in vaginal pH, hydration, and elasticity.
Patient safety
Why diagnosis comes first
Dryness, soreness, tearing or painful sex may reflect GSM, infection, dermatoses, pelvic-floor guarding or medication effects, so the treatment choice depends on assessment.
It checks the cause
**Symptom Resolution:** Clinical trials demonstrate profound reductions in vaginal dryness, dyspareunia (painful sex), itching, and burning.
It protects safety
**General Safety:** Highly biocompatible due to the extensive purification process that removes proteins and immunogenic matter, making allergic reactions extremely rare.
It reviews alternatives

It sets expectations
**Vaginal Ovules:** Daily intravaginal insertion for 2 to 4 weeks yields rapid, measurable improvements in vaginal pH, hydration, and elasticity.
Non-hormonal does not mean automatic
A hormone-free treatment may still be unsuitable if there is active infection, unexplained bleeding, pregnancy, recent surgery, severe fish allergy or unclear pelvic pain.
The consultation should cover product source, allergy risk, alternatives such as moisturisers or local hormonal care, and realistic timelines for tissue response.
Considerations
What to consider
**Administration:** Delivered via micro-injections directly into the vulvar skin dermis and mucosal lamina propria, or self-administered as topical ovules.
Consultation priorities
**Consultation & Assessment:** Clinical evaluation of GSM symptoms, ruling out active infections, and confirming patient eligibility.
Consent
Aftercare
Follow-up
Before treatment
**Consultation & Assessment:** Clinical evaluation of GSM symptoms, ruling out active infections, and confirming patient eligibility.
During care
**Pre-Treatment:** Patients are advised to stop blood-thinning supplements (e.g., aspirin, fish oils, NSAIDs) a few days prior to minimise bruising.
Aftercare
**The Procedure:** Precise intradermal injections of the polynucleotide gel into the targeted vulvovaginal tissues.
When to reassess
**Aftercare:** Patients must abstain from sexual intercourse for 24 to 72 hours, avoid hot baths, saunas, and vigorous exercise, and wear loose-fitting underwear to prevent friction.
Practical expectations
**Vaginal Ovules:** Daily intravaginal insertion for 2 to 4 weeks yields rapid, measurable improvements in vaginal pH, hydration, and elasticity.
**Comfort Measures:** For injectables, a topical anaesthetic cream is applied prior to the procedure to minimise stinging and discomfort.
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, usually used for gradual tissue-quality support rather than volume.
Myth: hormone-free means suitable for everyone
Reality: allergy, infection, bleeding, pregnancy, recent surgery and unexplained pain can still make treatment unsuitable.
Myth: hydration means instant repair
Reality: hydration may be noticed earlier, but collagen and tissue-quality changes are gradual and variable.
Evidence and limits
Mechanism-of-action language should not be treated as proof of a predictable clinical result.
Alternatives still matter
Moisturisers, local hormonal care, pelvic-floor physiotherapy, infection treatment or specialist review may be more appropriate 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 a treatment.
Are red flags absent?
Do not claim intimate polynucleotides cure dryness, laxity, sexual dysfunction, pelvic symptoms, scarring or menopause-related tissue change. Explain that PN products are often fish/marine-derived and allergy history matters.
Are alternatives clear?
Administration: Delivered via micro-injections directly into the vulvar skin dermis and mucosal lamina propria, or self-administered as topical ovules.
Is follow-up planned?
The clinic should explain aftercare, review timing and when to seek help.
Reassuring signs
Proceeding is more reasonable when goals are clear, red flags have been checked, and expectations are realistic.
No red flags
Follow-up plan
Reasons to pause
Pause treatment for active infection, unexplained bleeding, severe fish allergy, pregnancy, recent pelvic surgery or severe pain that has not been assessed.
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 or tongue, breathing difficulty, widespread hives, faintness or collapse after exposure needs urgent medical help.
Bleeding or infection
New post-menopausal bleeding, unusual discharge, fever, pelvic pain, thrush, BV or UTI symptoms should be assessed before injectable treatment.
Infection signs
Common Side Effects: Transient redness, swelling, mild tenderness, or bruising at the injection site, usually resolving within 24 to 48 hours.
Emergency symptoms
Call 999 in a life-threatening emergency, including collapse, chest pain or breathing difficulty.
