This New Cream Is Giving 40+ Skin Its Much-Needed Hormonal Reset

We’re told about what perimenopause and menopause can do to our bodies, but there’s much less about what the process does to our skin. Hormonal changes can transform the way our skin looks and feels. One minute your skincare routine is working just fine, the next your skin is dry, sensitive, thinner and somehow not responding to anything the way it used to. But figuring out what to use next can feel like a full-time job. Why is my skin suddenly so dry? Which active? How often? Can I use these together?

This new Australian skincare launch is taking a much simpler, medically guided approach that addresses the hormonal shift behind some of the most common signs of ageing.

The launch comes from The Secret, one of Australia’s most trusted names in skincare. Founded by Perth-based doctors Dr Clara Hurst and Dr Deb Cohen-Jones, the premium prescription-based skincare brand has built its reputation around simplifying medical-grade skincare, combining multiple active ingredients into straightforward, personalised routines. EstroRepair continues along the same line, with a first-of-its-kind oestrogen formulation, customised to you.

So, why would your skin need oestrogen?

If your skin has suddenly changed its mind about everything, there may be more going on than simply getting older.

Turns out oestrogen plays a major role in collagen production, hydration, elasticity and the skin barrier. As levels decline, these processes tend to slow down too. In fact, The Secret points to research suggesting that around 30% of collagen can be lost in the first five years of menopause, which honestly feels quite cruel considering everything else our bodies are going through.

It could also explain why skin that was once relatively easy to manage suddenly feels dry, thinner or less plump, and why your usual skincare routine isn’t quite cutting it.

Oestrogen and skin isn’t exactly new

Researchers have been studying topical oestrogen and its effects on skin for decades, including its impact on collagen, skin thickness, elasticity and wrinkle depth. Surprisingly, it’s one of the few skincare actives where researchers have actually looked under the hood, measuring changes directly using skin biopsies and microscopy rather than relying on photographs or self-reported findings.

In one six-month study of 59 women, researchers objectively measured changes in the skin and found an increase in collagen fibres and improvements in elasticity and firmness, alongside reductions in wrinkle depth and pore size.

Now, this isn’t proof that oestrogen is some sort of miracle cream. But it does suggest there’s a legitimate reason to be looking more closely at the relationship between oestrogen and our skin, and The Secret’s own EstroRepair trials support these findings too.

So, what’s actually in EstroRepair?

At the heart of the formula is estriol (E3), one of the body’s naturally occurring forms of oestrogen. The same one responsible for that “pregnancy glow”. Applied topically, estriol works by interacting with oestrogen receptors in the skin, helping support processes involved in collagen production, hydration, elasticity and barrier function. It’s paired with hyaluronic acid for hydration and barrier support, plus a nourishing base containing vitamins D and E. The active ingredients are then tailored to your individual skin needs.

At $200, EstroRepair is certainly an investment. But the idea is to simplify rather than add to your routine, bringing multiple active ingredients together in a personalised formula instead of requiring a separate product for every concern. And because it’s prescription-only, you also get guidance and support from medical professionals along the way.

And no, it’s not MHT in a face cream

EstroRepair isn’t intended to replace menopausal hormone therapy. The topical treatment is designed to target the skin without disrupting your body’s delicate hormonal system.

And before we go any further, The Secret makes it clear: we shouldn’t be applying vaginal oestrogen creams or body hormone gels to the face. These products are formulated for different purposes and contain different forms and concentrations of oestrogen. They’ll do more harm than good.

If you think you’re experiencing oestrogen-deficient skin, book a consult with The Secret’s medical team to discuss whether EstroRepair is suitable for you.

Could this be the next chapter of anti-ageing skincare?

For years, the conversation around skin after 40 has centred on slowing down ageing. EstroRepair takes a slightly different view: what if we focused less on fighting the visible signs and more on understanding why the skin is changing in the first place?

The Secret reports that 98% of participants in its six-week patient outcomes trial saw visibly firmer skin, while 92% reported improved luminosity and even tone and 86% reported improved hydration and plumpness.

These results, combined with decades of previous study, present a pretty compelling case. When hormones start changing, perhaps our approach to skincare needs to change with them.
