Does HRT make you look younger? What it does for skin, hair and collagen

Women on HRT often say their skin looks better. Partners notice. Friends ask what has changed. It is one of the most common unprompted comments we hear at follow-up, and it is also one of the most over-sold claims on the internet, so it deserves a straight answer.

The short version: oestrogen does a great deal for skin, losing it at menopause does visible damage quite quickly, and replacing it slows or partly reverses some of that. It does not undo sun damage, it is not a facelift, and it is not a reason on its own to take HRT.

What oestrogen does in skin

Skin is full of oestrogen receptors, which is why it changes so noticeably when levels fall. Oestrogen:

• Drives the fibroblasts that make collagen, the protein that gives skin its structure
• Supports elastin, which lets skin spring back
• Increases hyaluronic acid, which holds water in the skin
• Maintains the skin barrier and sebum production, so skin stays supple rather than dry
• Keeps blood flow to the skin up, which affects colour and healing

None of this is subtle. It is the same reason skin often looks its best in pregnancy, when oestrogen is high.

What happens at menopause

Studies going back to the 1980s found that skin collagen falls by around 30 percent in the first five years after menopause, and then by roughly 2 percent a year after that. That first drop is steep, which is why so many women describe their face “falling” over a couple of years rather than ageing gradually.

In practice this shows up as:

• Dryness and a rougher texture, often the first change women notice
• Thinner skin that bruises more easily and heals more slowly
• Deeper lines and loss of firmness along the jaw and neck
• A duller complexion as blood flow drops
• Itching, and sometimes a crawling sensation, from the drier skin and changes in nerve signalling

Because these changes coincide with other menopause symptoms, women often assume they are simply ageing. They are, partly. But the pace is hormonal.

What HRT does

Comparisons between women on HRT and women of the same age who are not show the HRT group with thicker skin, more collagen and better elasticity and hydration. The benefit is clearest in women who start HRT within a few years of menopause, while the collagen is still being lost quickly, rather than a decade later.

Studies measuring wrinkles directly are less consistent. Some show improvement, some show none, and the honest reading is that HRT helps the quality and thickness of skin more reliably than it smooths established lines. It makes no difference to sun damage or pigmentation, which are driven by ultraviolet light rather than hormones.

It does not matter much whether the oestrogen is a patch, a gel or a tablet as far as skin is concerned. The skin effect comes from circulating oestradiol, so a dose that controls your other symptoms is the dose that helps your skin.

Hair

Oestrogen keeps hair in its growing phase for longer, which is why hair often feels thicker in pregnancy and sheds afterwards. After menopause the growing phase shortens and the relative influence of androgens on the scalp increases, which can lead to thinning over the crown and a wider parting. This is female pattern hair loss, and it is common.

HRT can slow shedding for some women, and many report fuller hair. It is not, on its own, a treatment for hair loss, and it is not prescribed for that purpose. If thinning is marked, your doctor may suggest checking iron and thyroid, which are frequent contributors, and may discuss specific hair loss treatments separately.

Women are often worried that testosterone, where it is added to HRT, will make hair loss worse. At the low doses used for women, with blood levels kept in the normal female range and monitored, this is uncommon. It is one of the things your doctor watches for at reviews.

Why we will not prescribe HRT for your skin

HRT is prescribed for menopause symptoms and, in some women, to protect bone. The risks are small for most women and the benefits are real, but the balance only makes sense when there is something to treat. Prescribing a systemic hormone purely for appearance is not good medicine, and a clinic willing to do it is telling you something about its priorities.

What we will say is this: if you have symptoms that warrant HRT and you have been putting it off, better skin is one of the quieter benefits that comes along with sleeping through the night and thinking clearly again. Our guide to HRT in the UK sets out the risks and benefits properly so you can make that decision with the full picture.

Skin care that actually works alongside

Whether or not you take HRT, the things with real evidence for skin after menopause are unglamorous:

• Daily broad-spectrum sunscreen, which does more for lines than any cream
• A topical retinoid at night, which stimulates collagen and is the best-evidenced active ingredient there is
• A richer moisturiser than you used at 35, applied to damp skin
• Not smoking, which breaks down collagen faster than menopause does
• Enough protein, and vitamin C, which collagen production depends on

Oestrogen face creams are sold online and in some clinics. They are not licensed in the UK, the doses are uncontrolled, and we do not recommend them. For the genital skin, where thinning and dryness cause real discomfort, vaginal oestrogen is licensed, very safe and highly effective, and it is a different matter entirely.

The bottom line

Falling oestrogen thins skin, dries it and takes away its structure faster than normal ageing, and HRT measurably slows that and partly reverses it, especially when started close to menopause. It will not remove lines caused by the sun and it is not a reason to start HRT by itself. If you have symptoms, the skin is a bonus. A doctor who builds your HRT around your symptoms will get the dose right for the things that matter, and your skin will follow.
