Vaginal dryness could be your first sign of perimenopause. Here's what to look for.

Most of us are taught to watch for two signs of perimenopause: hot flushes and changes to our periods. So it can be genuinely disorienting when one of the earliest shifts shows up somewhere far more private — as vaginal dryness, often appearing before your cycle becomes irregular and well before any night sweats.

It is extremely common, it is a normal part of a normal transition, and once you understand what's happening, it becomes much easier to look after. This piece walks through the early signs, the biology underneath them, how perimenopause actually unfolds, and the evidence-based first steps you can take.

What perimenopause actually is

Perimenopause is the transition leading up to your final period, and it can last anywhere from a couple of years to a decade. Crucially, it usually begins several years before periods stop — commonly in the mid-40s, but for some women in the late 30s. During this window, oestrogen doesn't decline in a tidy straight line; it fluctuates, swinging higher and lower from cycle to cycle before gradually settling at a lower level. Those swings are why symptoms can come and go, and why dryness may be noticeable one month and barely there the next.

What's happening to the tissue

Oestrogen is the hormone that keeps the vulva and vagina healthy. Oestrogen receptors sit throughout the vagina, vulva, urethra and bladder, and when they're well supplied, oestrogen maintains blood flow, collagen, the thickness and elasticity of the tissue, and its natural moisture. It also keeps the vaginal lining rich in glycogen, which feeds the protective lactobacilli that keep your pH slightly acidic. As oestrogen begins to dip, the lining thins, produces less natural lubrication, loses a little elasticity, and the protective microbiome starts to shift. Because the change is gradual, the first symptoms are usually subtle rather than dramatic — which is exactly why they're so easy to dismiss.

THE SCIENCE IN BRIEF:  Oestrogen maintains vaginal blood flow, collagen, tissue thickness, glycogen and moisture. In perimenopause it fluctuates then falls, so the epithelium thins and natural lubrication drops — meaning dryness can appear early, even while periods are still regular.

The signs that are easy to miss

Early dryness rarely feels like a flashing warning light. More often it's a low-level discomfort you'd explain away as a bad-fabric day or a one-off:

• A tight, dry or slightly raw feeling, particularly after sitting for a while

• Chafing in jeans, or soreness during and after exercise or cycling

• A faint stinging, or a paper-cut sensation, especially externally on the vulva

• Feeling less naturally lubricated than you used to, even when you're relaxed and aroused

• A little more sensitivity to soaps, fragranced products or even urine

• Symptoms that wax and wane week to week, tracking the hormonal swings of perimenopause

Why catching it early genuinely helps

These tissue changes tend to be progressive if nothing is done, because the underlying hormonal shift continues. That isn't a reason to panic — it's the reason gentle, consistent care early on is so worthwhile. Across the major menopause and gynaecology guidelines, non-hormonal moisturisers and lubricants are positioned as recognised first-line care for these symptoms, precisely because starting sooner keeps tissue comfortable rather than waiting for it to become sore or for sex to become painful.

A gentle, evidence-aligned first step

A pH-matched, hormone-free daily moisturiser — such as our certified-organic Vaginal Moisturiser — is designed to rehydrate and soothe delicate tissue with regular use. It's formulated to be iso-osmotic, meaning it's balanced to suit the needs of your tissue rather than drawing moisture in or out of it (more on why that matters in our osmolality piece). For comfort during sex, a separate lubricant does a different job, and the two work well together.

When to see a clinician

If dryness is persistent or painful, or comes with unusual bleeding (including any bleeding after sex or between periods), sores, or signs of infection, it's worth raising with your GP. Early conversations make for simpler solutions, and there are both non-hormonal and prescription options — including local vaginal oestrogen — to discuss when you're ready. Dryness at a younger-than-expected age is also worth mentioning, simply to confirm the cause.
