How Hormones Affect Your Skin: Acne, Dryness & Perimenopause

Ciao, Beautiful!

Have you ever wondered how you can have oily, acne-prone skin at 16… fairly predictable skin at 35… and then suddenly find yourself dealing with pimples and dry skin around 48?

Hormones.

Not everything happening to our skin is hormonal, of course. Genetics, sun exposure, stress, medications, environment and the products we use all matter. But our skin is very responsive to hormones, which is why some of its biggest changes tend to show up during some of the biggest hormonal chapters of our lives: puberty, pregnancy and perimenopause.

And once you understand what’s happening underneath the surface, some of those seemingly contradictory changes, like being dry and breaking out at the same time, start to make a lot more sense.

We tend to associate puberty with estrogen in girls, and estrogen absolutely rises as the reproductive system matures. But when it comes to puberty-related acne, androgens are especially important.

During puberty, increasing androgen activity causes our sebaceous glands to grow and produce more sebum, or oil. More oil doesn't automatically mean acne, but combine that oil with dead skin cells inside a follicle and you've created the perfect environment for a clogged pore.

If that plug stays closed, you get a whitehead, otherwise known as a closed comedone. If the pore remains open, the contents react with oxygen and darken, forming a blackhead. That dark color isn't dirt—and scrubbing harder isn't going to wash it away.

Add bacteria and inflammation into the mix, and those clogged pores can become the red, tender pimples we traditionally think of as acne.

So even during puberty, hormones aren't necessarily "causing a pimple." They're changing the environment of the skin in a way that makes acne more likely.

And that distinction becomes even more important later in life.

Pregnancy brings dramatic changes in estrogen, progesterone and other hormones, and skin doesn't respond exactly the same way in every woman.

Some women experience the famous pregnancy "glow." Others suddenly develop acne, pigmentation such as melasma, dryness or greater sensitivity. Some women who already have acne see it become worse; others see it improve. ACOG notes that many common pregnancy-related skin changes are associated with hormonal shifts, although the exact cause of every change isn't fully understood.

That variability is an important lesson: your hormone numbers alone don't tell the whole story.

Your skin's sensitivity to those hormones matters, too.

And because pregnancy changes which acne treatments are appropriate, always check with your OB-GYN or dermatologist before continuing strong actives or prescription acne treatments during pregnancy. Azelaic acid is one ingredient generally considered acceptable during pregnancy, but treatment should still be individualized.

Then comes perimenopause. Here we go again.

Perimenopause generally begins sometime in the 40s, although it can start earlier, and estrogen doesn't simply fall in one neat straight line. It fluctuates, sometimes significantly, before eventually declining.

Menopause itself is reached after 12 months without a period, and the average age in the United States is around 51. So when we talk about the skin changes many women notice "around 50," we're often talking about the menopausal transition rather than age 50 being some hormonal switch that suddenly flips.

And this is where acne gets really interesting.

As estrogen declines, the relative influence of androgens can become greater, even when a woman's testosterone level isn't abnormally high. Research on adult female acne describes this relative androgen influence as one reason acne can appear or reappear during the menopausal transition.

That's different from saying that women simply "overproduce estrogen in their 30s" and then gain weight and develop acne. Hormones are much more complicated than that.

Testosterone and other androgens also change with age. They do not suddenly disappear at menopause, and women continue to have androgen production from the adrenal glands, ovaries to varying degrees, and conversion within peripheral tissues. What changes is the balance between hormones, and how our tissues respond to them.

In other words, you can have hormonally influenced acne without necessarily having dramatically elevated testosterone.

Skin changes alone can't diagnose perimenopause, but when they begin alongside changes in your menstrual cycle, hot flashes, night sweats, sleep disturbances or other midlife symptoms, hormones deserve a place in the conversation.

Some skin changes women may notice include:

• new or returning acne, often along the lower face or jawline

• skin that somehow feels dry and still breaks out

• increasing tightness, flaking or dehydration

• greater sensitivity or easier irritation

• rosacea or eczema that seems harder to manage

• more noticeable fine lines or crepey texture

• slower healing

• easier bruising or skin that simply feels more fragile

Declining estrogen has been associated with decreased collagen, reduced elasticity, changes in hydration and skin thickness, and slower wound healing.

This is one reason I've become such a believer in treating the barrier first, rather than immediately throwing stronger and stronger actives at changing skin.

One of estrogen's many roles appears to involve helping support skin hydration, collagen and normal barrier function. As estrogen declines, skin can lose moisture more easily and become thinner and more fragile. Research has also found changes in skin-surface pH around menopause, with pH tending to become higher, or less acidic, in menopausal women.

That acidic environment matters because your skin barrier isn't simply there to make your face look smooth. It's part of your body's defense system, helping limit excessive water loss while creating an environment that supports normal skin function and microbial balance.

So rather than saying estrogen itself "protects you from skin infections," I think the more accurate way to explain it is this: estrogen helps support several properties of healthy skin, and when those properties change, skin can become drier, more fragile and slower to recover.

That's exactly where barrier-first skincare starts to make sense.

Our Barrier-First Face Bundle was created specifically with dry, reactive or fragile-feeling skin in mind. Instead of constantly exfoliating or trying to force mature skin to behave like teenage skin, the goal is to replenish hydration, reduce unnecessary irritation and support the barrier that's already doing a very important job.

Hyaluronic acid is one of my favorite places to start.

And here's an important distinction: hyaluronic acid itself isn't an oil. It's a humectant, meaning it helps attract and retain water. Topical HA has been shown to improve skin hydration, which makes it especially useful when skin starts feeling dehydrated.

The finished product still matters because HA serums can contain other ingredients—including oils or emollients—depending on the formula.

If your skin is dry but easily congested, I like the idea of starting with water-based hydration. Apply your HA, then, if your skin tolerates it and still feels dry, follow with a moisturizer to help reduce moisture loss.

And when skin becomes very dry, reactive or fragile, that's where a barrier-supporting product can become especially helpful.

Hydration gives skin water and a moisturizer helps hold onto it.

And an oil or more occlusive finishing layer can sometimes help reduce water loss even further, but not every acne-prone person needs that final step.

Skin in perimenopause may be simultaneously thinner, drier and more reactive, which means the aggressive acne routine you tolerated at 20 may leave your skin angry at 48. The American Academy of Dermatology specifically cautions that treatments designed for teenage acne can sometimes be too drying for menopausal skin.

So one ingredient worth discussing with your dermatologist is azelaic acid.

Azelaic acid has evidence supporting its use for both acne and rosacea, and it has anti-inflammatory properties. It's often an attractive option for skin that is acne-prone but can't tolerate a parade of harsh actives. That doesn't mean nobody experiences irritation—any active can sting or bother sensitive skin—but it's one of the more versatile ingredients available.

Occasional superficial chemical peels may also help selected cases of acne by removing accumulated dead skin cells and excess oil from clogged pores. But I wouldn't describe peels as a universal treatment for "inflammation," particularly if your barrier is already irritated or your rosacea is flaring. Peel type, strength, skin type and the condition being treated all matter.

This is another place where more isn't always better.

Something people rarely think about is the vehicle a topical medication comes in.

The active ingredient may get all the attention, but an ointment, cream, lotion and gel don't necessarily behave the same way on your skin.

Ointments generally contain the highest proportion of oil and are the most occlusive, making them useful for very dry skin. Creams sit somewhere in the middle. Lotions are lighter, easier to spread and typically contain less oil. Gels and solutions can feel especially lightweight, although certain formulas, particularly alcohol-based ones, may sting compromised or inflamed skin.

That's why two people can use treatments with the same active ingredient and have very different experiences.

Your skin at 50 may need something completely different from what it needed at 25!

Adult acne doesn't automatically mean you have a hormonal disorder. In fact, many women with adult acne have normal androgen levels.

But if your acne suddenly becomes severe or is accompanied by things like irregular periods, significant unwanted facial hair, scalp hair thinning or other signs of androgen excess, it's worth discussing with a physician rather than treating the skin in isolation. Adult female acne can sometimes occur alongside conditions such as PCOS or other endocrine abnormalities.

This is where women's healthcare needs to be more connected.

A dermatologist can address what's happening in the skin. Your gynecologist or primary-care physician can look at the bigger perimenopause picture. And when symptoms suggest a possible endocrine issue, an endocrinologist may help evaluate what's happening hormonally.

Sometimes your face really is giving you information about something happening deeper inside.

Your genes matter, but they aren't the only thing influencing how your skin ages.

Epigenetics describes changes in the way genes are regulated without changing the underlying DNA sequence itself. Researchers are increasingly studying how outside influences including UV exposure, pollution, smoking, diet and stress interact with epigenetic pathways involved in skin aging.

That doesn't mean a face cream can "rewrite your genes," and I would be very suspicious of anyone promising that. But what it does mean is that your everyday choices still matter! 

Hormones may change the hand we're dealt, but there are still plenty of things we can do to support the health and resilience of our skin along the way.

The skin you had during puberty wasn't the same skin you had during pregnancy. And the skin you have during perimenopause isn't supposed to behave exactly like the skin you had at 30.

So if you're suddenly dealing with breakouts, sensitivity and dryness all at the same time, start with the basics: protect your barrier, replenish water, moisturize appropriately, use acne actives thoughtfully and don't be afraid to bring your dermatologist or women's-health provider into the conversation.

And if hormonal breakouts have also made it harder to figure out what kind of makeup or foundation will actually look good on your changing skin, watch my YouTube video on choosing foundation for hormonally induced, acne-prone skin here: https://youtu.be/nrEMTpgzpYA?si=SV26WVyfNg1-B0bt
