Dry, Thinner Skin After Menopause: What the Dermatology Literature Actually Says

The short version

• Skin after menopause really does get thinner and drier. Oestrogen decline is implicated in both reduced dermal collagen and increased water loss through the barrier (Kamp, 2022).
• Hormone therapy is a conversation for your doctor. Pooled data links it to better skin thickness, collagen and elasticity, but found no significant effect on dryness (Pivazyan, 2023).
• Humectants such as glycerine and hyaluronic acid make skin look and feel less dry. In one trial it was the added physiological lipids that improved the barrier itself (Andrew, 2025).
• Panthenol, or vitamin B5, has randomised evidence for better hydration and reduced water loss, from small studies (Gehring, 2000).
• None of those ingredient studies were run in postmenopausal women, and nothing applied to the surface reverses the structural change. What helps is modest: gentle cleansing, a humectant, a lipid rich moisturiser, daily sunscreen.

What the research measures

The most quoted number comes from a 1987 study of postmenopausal women. Skin collagen content, skin thickness and bone mass all declined by roughly one to two per cent per year after menopause, and the decline was significant when measured against years since menopause (Brincat, 1987).

That is a small sample by modern standards and nearly forty years old. The pattern it described has held up.

A more recent review describes oestrogen as implicated in transepidermal water loss, the standard laboratory measure of water escaping through the barrier, and in reduced dermal collagen. It also notes associations between menopause and xerosis, meaning dry skin, and pruritus, meaning itch (Kamp, 2022).

An earlier dermatology review reported epidermal thinning, declining dermal collagen content, diminished skin moisture and decreased laxity in postmenopausal women (Hall, 2005).

About hormone therapy

This belongs with your doctor, not with a skincare article and not with a salon.

The pooled data is worth knowing. A 2023 systematic review and meta analysis of fifteen studies covering 1,589 patients found that menopausal hormone therapy was associated with improvements in skin thickness, collagen content and elasticity.

The same analysis found no statistically significant effect on skin dryness, with a standardised mean difference of 0.15 and a confidence interval crossing zero (Pivazyan, 2023). The authors themselves concluded that more well conducted trials are needed.

Humectants

These are water binding ingredients such as glycerine and hyaluronic acid. They hold water in the outer layer, and the limit is worth stating plainly.

In a 2025 trial in adults with a history of eczema, a glycerine containing emollient reduced visible skin dryness but had no measurable effect on barrier integrity. A formulation containing physiological lipids plus glycerine improved both (Andrew, 2025).

Ceramides and physiological lipids

In that same trial, the lipid containing formulation significantly improved barrier integrity as measured by transepidermal water loss after tape stripping, reduced sensitivity to a standard irritant, and raised two specific ceramide species in the stratum corneum by 24 and 19 per cent (Andrew, 2025).

It is a single study of 58 people, run in people with an eczema history rather than in postmenopausal women. Read it as promising rather than settled.

Panthenol, or vitamin B5

A randomised, double blind, placebo controlled study found that seven days of topical dexpanthenol improved stratum corneum hydration and reduced transepidermal water loss compared with the vehicle alone (Gehring, 2000).

A later report covered two randomised studies of a panthenol containing emollient. Only the first, in 23 healthy subjects, measured hydration and water loss, finding a greater reduction in water loss and better hydration against control. The second, in 20 subjects, measured neither (Stettler, 2017).

That 2017 work was co-authored by staff at Bayer Consumer Care. It does not make the result wrong, but it should temper how much weight you give it.

Who these studies were done in

The barrier and ceramide work was done in adults with a history of eczema. The panthenol work was done in healthy volunteers. None of the ingredient studies were run in postmenopausal women.

Only the collagen, skin thickness and hormone therapy research here is menopause specific. Reading the ingredient findings across is reasonable, but that is our assumption rather than something those papers measured.

Where Medik8 Hydr8 B5 sits

We sell this serum, so weigh what follows accordingly. Hydr8 B5 is a hyaluronic acid and vitamin B5 serum, drawing on the ingredient groups above.

It was not tested in any study cited here, and the panthenol research was done on other formulations, so none of those results are a result for this product. It is a cosmetic product for hydration and skin feel, not a treatment for anything.

What to actually do

• Be sceptical of anything sold as menopause skincare that implies it addresses the hormonal change itself. Nothing in a jar does that.
• Cleanse gently, put a humectant serum on slightly damp skin, then a lipid or ceramide rich moisturiser over the top. Sunscreen daily.
• Layering a serum under a cream is ordinary practice rather than a finding from these studies. None of them tested it.
• Expect modest results. Most of the barrier trials are short, small, run in general or eczema prone groups, and several are funded by the companies selling the formulation.
• If dryness is severe, persistent or itchy, that is a GP or dermatologist conversation, not a skincare one.
