The 3am wakeWhy do I wake at 3am in perimenopause?
You fall asleep fine, then wake at 3am, wide awake, heart going. It is one of the earliest and most reliable signs of the transition, and it has a mechanism.

Skin changingWhy has my skin changed in perimenopause?
Something has changed and you cannot name which change it is. There are two hormonal directions here, they want different routines, and mixing them up is the usual reason skin gets worse.

The routineWhat does a menopause skincare routine actually need?
Four steps, not fourteen. What the routine has to do now is different from what it did at 35, and two of the steps that matter most are the two nobody sells hard.

Sudden drynessWhy has my skin turned dry in perimenopause?
Skin that behaved for years turns dry, tight and duller, seemingly overnight. Oestrogen falls, and the skin barrier falls with it.
Read this one
Brain fogWhy do I have brain fog in perimenopause?
The word goes missing mid-sentence. You walk into a room and forget why. It is one of the most frightening symptoms, because of what women fear it means, and it is a documented part of the transition.
Read this one
The tirednessWhy am I so tired in perimenopause?
Tired on waking as if the night did not count, or a wall at three, or flat all day. Most of it is the night arriving in the day, and the rest is two things a blood test finds.
Read this one
Running warmWhy do I get hot flushes and run warm in perimenopause?
It starts as warm nights, then becomes a flush that arrives without warning, day or night. The thermostat that held for decades has narrowed.

Aching jointsWhy do my joints ache in perimenopause?
Stiff on waking, slow out of a chair, hands and knees and hips. The most commonly reported symptom of the transition in Australian data, and mostly not the joint wearing out.

Newly reactiveWhy does my skin react to everything in perimenopause?
The retinol you used for years now stings. A cleanser leaves you red. Skin that tolerated everything has started to react, and the barrier is the reason.
Read this one
New anxietyWhy am I anxious for the first time in perimenopause?
A new edginess. Anxiety in a way that is unfamiliar, often worst in the days before a period. For many women it is the symptom that is hardest to attribute to the transition.
Read this one
Irritability and rageWhy am I so irritable in perimenopause?
Anger out of proportion to what set it off, gone in an hour, then shame. Two calming systems loosen at once, it clusters before a period, and it is not who you have become.
Read this one
The new itchWhy is my skin itchy in perimenopause and menopause?
Skin that itches at night, arms, shins, back, often with nothing visible on it. Some women feel crawling, like a hair that is not there. It is one of the least discussed symptoms of the transition, and one of the most common.
Read this one
Rashes and rednessWhy am I getting rashes in menopause and perimenopause?
Hives that arrive from nowhere. Red, blotchy patches after a shower. Old products, old jewellery, old washing powder, suddenly leaving marks. Rashes get more common in the transition, and there is a reason.

The face in the mirrorHow does menopause change my face?
It seems to happen inside eighteen months: the face in the mirror softens at the jaw, hollows at the cheek, dulls in the light. You are not imagining the speed. The transition is when the scaffolding changes.
Read this one
New facial hairWhy am I growing facial hair in menopause?
A wiry hair at the chin where there was down. Another at the jaw. New facial hair is one of the most common and least discussed arrivals of the transition, and the mechanism is a ratio, not a malfunction.
Read this one
Hair thinningWhy is my hair thinning in perimenopause?
A parting wider than it was, or handfuls in the brush. Two different things that look alike, only one grows back on its own, and both want the same two blood tests first.
Read this one
Adult breakoutsWhy am I breaking out in perimenopause?
Breakouts along the jaw in the same month your cheeks have never been drier. Skin that is somehow oily and parched at once. Adult breakouts in the transition are real, common, and they do not answer to teenage products.

The symptoms of perimenopause, and what drives each one.
Perimenopause is the years before the final period, usually four to six of them, when progesterone falls first and oestrogen swings before it falls. Each symptom on this page is one of those two changes showing up somewhere: in sleep, in the brain, in mood, on the skin, in the body’s thermostat. Each has a mechanism, a usual time of arrival and a first move.
Every symptom, its driver, and where to start.
Compare symptoms at a glance
| Symptom | What drives it | When it usually starts | The first move |
|---|---|---|---|
| The 3am wake | Progesterone falls first, and its calming metabolite with it | Often the first sign, from the late thirties | Magnesium glycinate in the evening, and a protein dinner |
| Skin changing | Oestrogen falls and takes the seal and the scaffold; androgens do not fall with it | Often before the cycle changes, and across the whole transition | Name which direction it is, then run the shared floor for a fortnight |
| The routine | A thinner barrier and less collagen change what a routine has to do | From the first year the old routine stops working | Cleanser, moisturiser, sunscreen, then one active after a fortnight |
| Sudden dryness | Oestrogen supports oil, water and the barrier lipids | Through the transition, often before the cycle changes | A gentler cleanser, then cream onto damp skin |
| Brain fog | Oestrogen swings unsettle word retrieval and the brain's fuel supply | Tracks the broken sleep, often from the early forties | Protect sleep first, then protein and movement |
| The tiredness | Broken, shallower sleep, with low iron or thyroid hiding underneath | Tracks the 3am wake, often from the early forties | Full blood count, ferritin and thyroid function, then protect the night |
| Running warm | Falling oestrogen narrows the temperature band the body tolerates | Warm nights first, then day flushes, mid transition on | A cooler bedroom, and fewer swings from alcohol and caffeine |
| Aching joints | Oestrogen's support for cartilage, tendon, muscle and bone falls | From early perimenopause, before the cycle visibly changes | Look for swelling first, then a daily walk and strength twice a week |
| Newly reactive | A thinner barrier lets actives reach deeper and faster | Alongside the dryness, often on a product that used to be fine | Stop the actives for a fortnight, then reintroduce one |
| New anxiety | Progesterone's calming metabolite falls first, oestrogen unsettles serotonin | Often worst in the days before a period, from the early forties | The same basics that steady sleep, and a two-month cycle log |
| Irritability and rage | Progesterone's calming metabolite falls first; oestrogen swings | Often before the cycle visibly changes, from the late thirties | Magnesium at night, a two-month cycle log, and one plain conversation at home |
| The new itch | Fewer ceramides and less water, and warmth turns it up | Often at night, through the transition and after | Wash warm and short, then cream onto damp skin |
| Rashes and redness | A thinner barrier, more heat at the surface, and hives that run on histamine | With the flushes and the dryness, mid transition on | A month of fragrance-free everything, and patch-testing |
| The face in the mirror | Collagen tracks oestrogen, fat pads thin, dry skin scatters light | The first years around the final period | Protein, sunscreen, sleep, then actives at named doses |
| New facial hair | Oestrogen falls steeply while testosterone drifts, so the ratio tilts | Past the final period, about two in five women | Remove it freely, and match the method to the hair colour |
| Hair thinning | Oestrogen's growing-phase support falls; iron and thyroid decide recovery | Through the transition, and in waves after a shock | Decide pattern loss or shedding, then ferritin and thyroid function |
| Adult breakouts | The oestrogen to androgen ratio shifts, on a drier barrier | Jawline breakouts alongside dryness, mid transition on | Stop the drying products, rebuild, then one active |
