Replens Long-Lasting Vaginal Moisturizer review: does it work for menopause dryness?
Replens is one of the few vaginal moisturizers tested in a large independent trial, where it eased dryness about as well as low-dose vaginal estrogen, though neither beat a placebo gel. Its "up to 3 days" and "9 out of 10" claims come from the brand without published detail.
See a doctor for any bleeding after menopause, unusual discharge or odor, sores, persistent burning or itching, or pain with sex that does not improve. If you have had breast cancer, talk to your cancer team about vaginal treatments.
What it is and what the brand claims
Replens Long-Lasting Vaginal Moisturizer is a hormone-free gel made by Church & Dwight. It is sold over the counter in many countries.
The brand says it lasts up to three days. It describes a bioadhesive that clings to dry vaginal cells and supplies moisture until those cells are shed.1 It calls the product clinically tested, doctor-recommended and FDA-cleared, and says 9 out of 10 women love it, without giving study details.1
This page is an evidence review, not a hands-on test. It is based on published research, regulator statements and the brand's own claims.
What is in it and how it works
According to the 2018 trial paper, Replens contains purified water, glycerin, mineral oil, polycarbophil and carbomer.2 It is a thick gel with an acidic pH of about 3.0.2
Polycarbophil is a water-holding polymer that sticks to the vaginal lining, so it moisturizes for longer than a lubricant. The brand page does not name polycarbophil.1 Replens contains no hormones, so it eases symptoms rather than reversing the thinning caused by low estrogen.
What the polycarbophil moisturizer trials show
The best evidence is a 2018 randomized trial funded by the US National Institutes of Health. It enrolled 302 postmenopausal women for 12 weeks.2 Women got either a low-dose vaginal estrogen tablet, Replens, or a placebo tablet with a placebo gel.2 The trial was funded by the National Institute on Aging, which had no role in its design or reporting.2
The most bothersome symptom improved by a similar amount in all three groups. Neither Replens nor estrogen did significantly better than the placebo.2 The authors suggested women could choose by cost and preference.2
Two details matter. Estrogen changed tissue markers, such as vaginal pH, and more estrogen users reported a meaningful benefit.2 The placebo gel was similar in thickness to Replens, and may itself have worked as a moisturizer.2,3
An earlier systematic review also suggested vaginal moisturizers may work about as well as vaginal estrogen for symptoms.4 Other moisturizer types, such as hyaluronic acid gels, have their own small trials.5 The brand's three-day and "9 out of 10" claims are not backed by published detail on its page.1
Side effects: residue, irritation and other cautions
In the 2018 trial, side effects did not differ between groups. Yeast infections occurred in 2% of women using Replens, the same rate as placebo.2
- Residue: the brand says the gel and dead cells are "eliminated naturally" as cells renew.1 This can show up as a white or clumpy residue or discharge, which is usually harmless but can be mistaken for thrush.
- Irritation: its pH of about 3.0 is more acidic than the placebo gel used in the trial (4.5).2 Some people find gels sting on very dry or sore tissue. Stop using it and seek advice if burning or itching lasts.
- Condoms: it contains mineral oil,2 and oils can weaken latex condoms; ask a pharmacist if you rely on them.
- No listed warnings: the brand page does not list side effects, so check the pack leaflet.1
Who it might suit and alternatives
Replens may suit women with ongoing internal dryness who want a hormone-free option with real trial data. It is also an option for people who cannot or prefer not to use estrogen. If you have had breast cancer, check with your cancer team before choosing any vaginal treatment.
The trial found a basic gel worked about as well. So a cheaper moisturizer is a reasonable first try, or a switch if Replens irritates. Lubricants are still useful during sex.

Price and value
Replens is a one-off purchase sold in packs at pharmacies, supermarkets and online. Check current price. The 2018 trial suggests a simpler moisturizing gel may work similarly, so price is a fair way to choose.2
What it is used for: evidence rated

|---|---|---|
| Vaginal dryness (polycarbophil gel) | In a 302-woman NIH-funded trial, symptoms improved as much as with vaginal estrogen, though not more than placebo gel.2,4 | |
| Compared with vaginal estrogen | Similar symptom relief in the 2018 trial, but only estrogen changed tissue markers.2 | |
| Pain or discomfort with sex | Sexual function scores did not improve more than with placebo in the 2018 trial.2 | |
| "Lasts up to 3 days" | Brand claim; the brand page gives no study details.1 | |
| "9 out of 10 women love it" | Brand satisfaction claim, not a clinical outcome.1 |
