Most women are told about hot flushes. Far fewer are told that the tissue between their legs is going to change, that the change is progressive, and that unlike hot flushes it does not resolve on its own.
Vulvar and vaginal dryness in perimenopause has a clinical name, genitourinary syndrome of menopause, and it is one of the most common chronic conditions associated with this stage of life. It is also one of the least discussed, which is why so many women assume they are the only one.

What is actually changing
Perimenopause is the run-up to your final period, and it typically begins in your forties, though some women notice changes in their mid-thirties. On average symptoms start about four years before the last period, and most people have begun by 45 to 47.
The mechanism is estrogen. There are cells throughout the vulva, vagina and surrounding tissue that respond to estrogen, and as production falls those tissues change. They become thinner, less elastic and less able to hold moisture. Secretions diminish. The clinical term for this pattern is genitourinary syndrome of menopause, or GSM, which replaced the older and narrower term vulvovaginal atrophy.
The scale of the hormonal shift is worth stating: menopause involves roughly a 95% reduction in estrogen production. This is not a subtle adjustment.
How common it really is
Reported prevalence of GSM ranges from 14% to 87% among postmenopausal women, depending on how studies define and ask. That range is wide because many women do not report it unprompted.
The more consistent figure: approximately 75% of women experience vaginal dryness following menopause.
Three quarters. If you are experiencing this, you are in the majority, and the reason it feels isolating is that the conversation has not caught up with the prevalence.
What it feels like, beyond dryness
Dryness is the headline but it is rarely the whole picture. The documented signs and symptoms of GSM include burning, irritation, vulvovaginal dryness, pain during sex, and urinary symptoms including urgency, discomfort passing urine, and recurrent urinary tract infections.
Women often describe it in ways that do not sound like a hormone problem at first:
- clothing seams that never used to register now feel abrasive
- a sensation of tightness that does not ease after a shower
- irritation that appears after exercise and lingers
- a cycle of feeling raw, treating it as an infection, and testing negative
That last one matters. GSM is regularly mistaken for recurrent thrush, and a course of antifungal treatment for a problem that is not fungal does nothing except delay the right answer.
Why it does not go away by itself
Hot flushes eventually stop for most women. GSM does not.
Because it is driven by an ongoing hormonal state rather than a transition, symptoms tend to persist and often progress without management. This is the single most useful thing to understand, because it changes the decision from "wait this out" to "build a routine."
What the guidelines recommend first
Here is where the evidence is clearer than most people expect.
The most recent North American Menopause Society position paper on GSM sets out a step-up approach. First-line therapies are non-hormonal lubricants used with sexual activity, and regular use of long-acting moisturisers two to three times a week. That recommendation carries level A evidence, the strongest grade.
Read that again, because it inverts what most women assume. The first-line recommendation is not a prescription. It is consistent, scheduled moisturising. Prescription therapies including low-dose vaginal estrogen step in for persistent or moderate to severe symptoms.
The word doing the work is "regular." Two to three times a week, ongoing, not when it flares.
What the trials show about non-hormonal moisturisers
Two findings are worth knowing before you decide anything.
A systematic review published in Annals of Internal Medicine assessed hormonal treatments and vaginal moisturisers for GSM. And a 12-week randomised trial of 302 women found vaginal moisturisers showed comparable efficacy to low-dose vaginal estrogen and to placebo gel in reducing the most bothersome GSM symptom.
Separately, a prospective randomised study found a hormone-free moisturising cream was not inferior to an estriol cream for treating symptoms of vulvovaginal atrophy.
Two honest caveats. The 302-woman trial found moisturisers comparable to estrogen and to placebo, which tells you the placebo arm also improved and that some of the benefit is regular gentle attention to the tissue rather than any specific formulation. And these are studies of vaginal moisturisers, a different product category from an external vulvar balm.
What they support is a reasonable position: for mild to moderate symptoms, consistent non-hormonal moisturising is a legitimate first step with real evidence behind it, not a consolation prize.
Building a routine that holds
The guidelines say two to three times a week. In practice, the women who stick with it are the ones who attach it to something they already do.
Externally, a balm applied to the vulva, labia and any area that feels tight. This is where an external vulvar balm belongs, and where the "regular" instruction matters more than the ingredient list. Something you apply consistently beats something better that sits in a drawer.
During sex, a water-based lubricant, which the guidelines list as first-line alongside moisturisers. Lubricant and moisturiser are not interchangeable. One is for the moment, the other is for the tissue.
What to stop doing: soap on the vulva, which is alkaline against skin that is already compromised. Scented products. Anything marketed for freshness. If you are washing, what you wash with matters more now than it did at thirty.
One thing to skip: coconut oil is widely recommended for this, and there is pilot evidence it moisturises, but its alkaline pH and latex incompatibility make it a poor default.
When to see a clinician
Non-hormonal first-line is genuinely first-line, not a reason to avoid care. Book an appointment if:
- symptoms are moderate to severe, or persist after eight to twelve weeks of consistent moisturising
- there is bleeding, an unusual lesion, a change in skin colour or texture, or thickening
- itching is intense rather than a background irritation, which can point to lichen sclerosus rather than GSM
- you have recurrent urinary tract infections
- sex is painful enough that you are avoiding it
Low-dose vaginal estrogen is effective and acts locally. Many women rule it out on assumptions about systemic hormone therapy that do not apply. That is a conversation worth having on facts.
Frequently asked questions
At what age does vulvar dryness usually start?
Most women notice perimenopausal changes in their forties, some in their mid-thirties, and the average onset of symptoms is about four years before the final period. Dryness often appears later in perimenopause than irregular periods, so it can arrive after you have already adjusted to other changes.
Is vulvar dryness the same as vaginal dryness?
They usually occur together but they are different tissues. Vaginal dryness affects the internal canal. Vulvar dryness affects the external skin, the labia and surrounding area, and it responds to different products. An external balm and an internal moisturiser are not substitutes for one another.
Will it go away on its own?
Generally no. Unlike hot flushes, which resolve for most women over time, GSM is driven by an ongoing hormonal state and tends to persist or progress without management. This is why the guidelines emphasise regular use rather than treating flare-ups.
Do I have to use estrogen?
Not necessarily. The NAMS step-up approach places non-hormonal lubricants and regular long-acting moisturisers as first-line with level A evidence, and reserves prescription therapy for persistent or more severe symptoms. Trial data has found non-hormonal moisturisers comparable to low-dose vaginal estrogen for the most bothersome symptom.
How often should I apply a moisturiser?
The guideline figure is two to three times a week for long-acting moisturisers, used regularly rather than reactively. External balms can be used more often if the skin is uncomfortable. Consistency matters more than quantity.
Could it be something other than menopause?
Yes. Vulvar itching and irritation in this age group can also be lichen sclerosus, contact irritation from soaps or detergents, or an infection. GSM and lichen sclerosus can occur at the same time. Persistent itching, colour change or skin thickening should be examined rather than assumed.
