Why Men and Women Age Differently: The Science Behind Facial Ageing
Last updated: September 2026
It is one of the most common observations I hear in my clinic room in Hale, usually delivered with some irritation.
"My husband has done nothing to his skin his entire life and he looks fine."
The frustration is understandable and the observation is real. But the usual explanation, that men simply age better, is wrong, and the actual explanation is far more interesting.
Men and women are not ageing at different speeds. They are ageing on different shaped curves.
Male skin loses collagen in a more or less straight line from around the age of twenty. Female skin holds fairly steady into the late forties and then drops sharply. So a man of thirty-five has been losing collagen quietly for fifteen years, while a woman of thirty-five has barely started. She then loses in about a decade what he has lost gradually across thirty years.
The total is not wildly different. The experience of it is completely different, and that is why one of you feels ambushed and the other has not noticed anything happening at all.
This article explains the biology properly, including an honest look at the most repeated statistic in menopause skincare.
Key Takeaways
| Question | Short answer |
|---|---|
| Do men really age better? | Not better. Differently. Male collagen declines steadily from about 20; female skin holds and then falls sharply around 50 |
| Is male skin thicker? | Yes, by roughly 10 to 20%, which gives more structural support |
| Do women lose 30% of collagen after menopause? | That figure comes from a 1987 study and says "up to 30%". The direction is right, the precision is overstated |
| What drives the difference? | Oestrogen withdrawal in women versus a slow testosterone decline in men |
| What else differs? | Skin thickness, sebum, fat distribution, bone structure and lifetime sun exposure |
| Can you change any of it? | The hormonal curve, no. The sun exposure, skin quality and how you look after it, substantially |
| What matters most? | Daily sun protection, for both sexes, by a wide margin |

The Two Different Curves
This is the part almost every article on this subject misses, and it comes from research first published in the 1970s.
A review in the International Journal of Women's Dermatology summarises it clearly. Work by Shuster and colleagues found that:
| Men | Women | |
|---|---|---|
| When collagen decline starts | Around age 20 | Later |
| Shape of the decline | Linear. A steady downward line | Largely flat, then a sharp fall |
| When the change becomes obvious | Gradually, across decades. Rarely a single noticeable moment | Around 50, often described as happening "overnight" |
| Skin thickness through midlife | Declining throughout | Remains relatively constant until about 50, then decreases |
So the honest framing is not that men age more slowly. It is that men start earlier and lose gradually, while women start later and lose abruptly.
This explains several things that otherwise make no sense:
- Why women feel ambushed. A decade of visible change compressed into a few years registers as a sudden event, which is exactly how patients describe it
- Why men rarely notice. Losing a little every year for thirty years produces no moment at which anything obviously changed
- Why male ageing looks different when it arrives. Deeper, more established lines on thicker skin, rather than fine lines on thinner skin
- Why timing matters more than effort. A woman noticing change at 52 is not behind. She is on schedule for her curve
Is Male Skin Really Thicker?
Yes, though by less than is usually claimed.
The same review reports male skin as approximately 10 to 20% thicker than female skin, with higher collagen density. You will frequently see 25% quoted online. That figure appears to have grown in the retelling.
What the extra thickness actually buys:
| Consequence | Detail |
|---|---|
| More structural support | Thicker dermis resists creasing for longer, so fine lines tend to appear later |
| Deeper lines when they arrive | Thicker skin creases more decisively. Male frown lines are frequently more pronounced than a woman's of the same age |
| More sebum | Men produce more sebum across most facial areas, and it stays relatively stable through life. In women it declines progressively, which is part of why dryness becomes a midlife complaint |
| Different pH | Skin surface pH is higher in women, which has implications for barrier function |
None of that is something anyone can change. It is context for why the same routine produces different results in two people living in the same house.
What Oestrogen Actually Does for Skin
Oestrogen receptors are present throughout the skin, and oestrogen influences most of the things that determine how skin looks and behaves.
| What oestrogen supports | What happens when it falls |
|---|---|
| Collagen production | Loss of firmness. Lines that used to spring back stay put |
| Dermal thickness | Skin becomes measurably thinner and more fragile |
| Hydration and barrier function | Dryness, tightness, and new sensitivity to products tolerated for years |
| Elasticity | Reduced recoil. Skin takes longer to return after being stretched |
| Blood flow to the skin | Loss of the colour and light reflection that reads as "healthy" |
| Wound healing | Marks and blemishes take noticeably longer to settle |
The menopause typically occurs between 45 and 55, and the fall in oestrogen is comparatively abrupt. That is the whole reason the female curve has a cliff in it where the male curve does not.
The 30% Claim, Examined Honestly
You will have seen this figure. It is on packaging, in advertising, on social media, and it has been on this website. It usually appears as a flat statement: women lose 30% of their skin collagen in the first five years after menopause.
Here is where it actually comes from, because I think you should know.
| What people say | What the source says |
|---|---|
| "Women lose 30% of collagen" | The original wording is "up to 30%", which is a ceiling rather than an average |
| Presented as current science | The figure traces to a study published in 1987, and has been repeated for nearly forty years |
| Framed as a new discovery, the "collagen cliff" | The underlying observation appears in papers going back to the 1940s |
| Quoted as though it applies to everyone | Individual variation is considerable, and the studies behind it are small by modern standards |
Writing in The Conversation, anatomist Adam Taylor examined the "collagen cliff" framing and concluded that the picture is a good deal more complex than the slogan suggests, and that the science is more useful than the hype.
To be clear about what I am and am not saying. The underlying phenomenon is real. Oestrogen supports collagen, collagen falls after menopause, and the fall is steeper than the background rate of ageing. What is overstated is the precision. "Up to 30%, from a 1987 study, with wide individual variation" is the honest version, and it is still quite enough reason to take midlife skin seriously.
I am flagging it because you will see that number used to sell things, and a figure repeated confidently for forty years without qualification is worth recognising when you meet it.
Why Testosterone Behaves Differently
Men do experience hormonal change with age. Testosterone declines from around the age of thirty, at roughly 1% a year.
That is the crucial difference. It is a gentle slope, not a step. There is no male equivalent of the menopause in which a hormone supporting skin structure falls away over a handful of years.
The consequence is that male skin change is:
- Continuous rather than punctuated
- Harder to notice, because nothing happens quickly enough to prompt a look in the mirror
- Cumulative, which is why male ageing tends to show up as established, deeper lines rather than a sudden change in skin quality
It also means men rarely get the prompt that sends women to a clinic. Nobody wakes at 52 and thinks their face changed over the winter.
Fat, Bone and Structural Differences
Facial ageing is not only about skin. Underneath it, fat and bone are changing too, and here the sexes differ again.
Fat
Facial fat is not a single layer. It sits in discrete compartments separated by fibrous barriers, and those compartments lose volume and shift independently of one another. That is why a face can look hollow at the temple and heavy at the jaw simultaneously, which makes no sense under the older "everything slides downwards" model.
In women, volume loss frequently becomes noticeable after menopause, particularly in the cheeks, temples, under-eye area and along the jawline. Men often retain fullness in certain areas for longer, which helps preserve the underlying shape of the face.
Bone
The facial skeleton remodels throughout life, and the areas that resorb are predictable: the maxilla in the midface, the bone around the nose, parts of the orbital rim, and the region just in front of the jowl.
Men generally start with a larger facial skeleton, stronger brow ridges, more defined jawlines and more prominent cheekbones, so there is more structure to lose before the change becomes obvious. In women, bone density decreases more rapidly after menopause, and that affects the framework everything else sits on.
Much of what people interpret as sagging skin is skin fitting perfectly well over a structure that has shrunk beneath it.
Muscle and expression
Repeated contraction of the facial muscles creates dynamic lines, which over years can become visible at rest. Where those lines appear most prominently depends partly on which expressions a person makes most, and habitual expression patterns do differ between individuals. This is the least well evidenced of the differences discussed here, and I would not put more weight on it than that.
What I Can and Cannot Help With
| What this clinic does | What belongs with your GP |
|---|---|
| Assessing how your face has changed and explaining what is driving it | Menopause care, HRT, and hormonal symptom management |
| Cosmetic treatments aimed at skin quality and facial balance | Diagnosing any medical skin condition |
| Medical grade skincare and barrier repair | Investigating a mole or a changing lesion |
| Telling you honestly when the answer is sun protection rather than a treatment | Anything that is not purely cosmetic |
On the menopause point in particular: if your skin has changed alongside other symptoms, that is a conversation for your own GP or a menopause specialist, who can see the whole picture. Many women on appropriately prescribed HRT notice their skin improving as a secondary benefit, but skin is not an indication for it and it is not something I manage.
Frequently Asked Questions
Do men really age better than women?
Not better, differently. Male collagen declines in a straight line from around twenty, while female skin holds fairly steady until about fifty and then falls sharply. The total loss is not wildly different. The experience is.
Why does my skin suddenly look different at 50?
Because for you it genuinely is sudden. Oestrogen supports collagen, dermal thickness, hydration and elasticity, and it falls over a relatively short period. You are compressing into a few years what men spread across three decades.
Is it true women lose 30% of collagen after menopause?
The figure comes from a 1987 study and the original wording is "up to 30%", which is a ceiling rather than an average. The underlying phenomenon is real and worth taking seriously. The precision in how it is usually quoted is not.
How much thicker is male skin?
Roughly 10 to 20% thicker, with higher collagen density. You will often see 25% quoted. That figure has grown in the retelling.
At what age does collagen loss start?
For men, from around twenty, steadily. For women, the decline is gentler until the late forties and then accelerates sharply around the menopause.
Why do men get deeper wrinkles?
Thicker skin resists creasing for longer, but when it does crease it does so more decisively. Men also have historically had far more unprotected sun exposure, which coarsens texture.
Does shaving help men's skin?
It provides daily mechanical exfoliation, which supports cell turnover. It also irritates the barrier, so it is not a straightforward benefit. It is certainly not a skincare routine.
What are the first signs of facial ageing?
Usually fine lines around the eyes, changes in skin texture, reduced radiance, subtle loss of volume and small changes in brow or eyelid position. They develop gradually and are heavily influenced by sun exposure.
Can anything change the hormonal part?
Not through skincare. HRT addresses oestrogen deficiency properly for women who need it, and many notice skin improving as a secondary effect, but that is a conversation for your GP about your symptoms as a whole.
Why do I look tired rather than old?
Because the cues people read most strongly are under-eye shadows, brow position and skin dullness, and all three signal fatigue rather than age. It is also why those are the most satisfying things to address.
Is it too late to start looking after my skin?
No, at any age. Sun protection started at sixty still protects the collagen you have at sixty. The best time to start is whenever you decide to.
What is the single most useful thing either sex can do?
Daily broad spectrum sun protection. It costs less than anything else on this page and the evidence for it is stronger than for everything else combined.
