Understanding the Changes in Skin After 45
If your skin has started behaving in ways that feel entirely foreign to you, you are not alone. Many women in their mid-forties and beyond describe similar experiences: products that worked beautifully for years suddenly feel wrong, skin that was once oily has become parched, and a general sense that the face in the mirror belongs to a stranger. This is not your imagination, and it is not simply ageing. It is oestrogen.
Oestrogen is one of the most powerful regulators of skin health in the female body. It stimulates collagen production, supports the skin barrier, helps retain moisture, and keeps oil glands functioning. When oestrogen levels begin to decline during perimenopause, typically from the mid-forties onwards, the effects on skin are real, rapid, and wide-ranging.
What Actually Changes, and Why
Collagen is the structural protein that gives skin its firmness and bounce. Oestrogen plays a direct role in its production, which is why the decline in oestrogen during perimenopause and menopause leads to a measurable loss of skin density. The change can feel sudden because, for many women, it is. The perimenopausal years are marked by an accelerated rate of collagen loss compared to the years that come before or after.
At the same time, the skin’s ability to hold onto water decreases. Oestrogen supports the production of hyaluronic acid, a naturally occurring substance that draws moisture into the skin. As levels fall, so does the skin’s capacity to stay hydrated. The result is that dry, tight feeling that no amount of moisturiser seems to fully address.
The skin barrier, which is the outermost layer of skin responsible for keeping moisture in and irritants out, also becomes less robust. This is why skin that was once resilient suddenly reacts to products, weather, or stress in ways it never did before. Sensitivity, redness, and a general feeling of skin being easily upset are all common complaints during this transition.
The Changes That Catch Women Off Guard
Beyond dryness and loss of firmness, the hormonal shifts of menopause can trigger changes that feel particularly unexpected. Adult acne is one of them. As oestrogen declines, androgens (male hormones present in smaller amounts in women) can become relatively more dominant, stimulating oil glands and contributing to breakouts, particularly around the chin and jaw.
Hair thinning at the scalp, and in some cases increased facial hair, can also occur for the same hormonal reasons. Melasma, or patchy pigmentation, may worsen due to increased sensitivity to UV exposure during this time. And the fat padding beneath the skin, which gives the face its structure and volume, gradually diminishes, contributing to changes in facial contour that no topical product can fully reverse.
What This Means for Your Skincare
Understanding what is happening beneath the surface is the first step to making better decisions about how to care for your skin. The products and routines that served you in your thirties were designed for different skin with different needs. Menopausal skin requires more focus on barrier repair, deep hydration, and targeted support for collagen.
The good news is that this stage of life has never been better served by skincare science. Ingredients that genuinely address the concerns of oestrogen-depleted skin, from ceramides to peptides to retinoids, are widely available and well understood. The articles in this series will walk you through each of them in detail.
The other piece of advice worth holding onto from the outset is this: what your skin needs right now may be quite different from what it needed five years ago, and different again from what it will need in five years time. The women who navigate this transition most successfully are the ones who stay curious, stay flexible, and stop expecting their skin to behave as it once did.
