How Hormones Affect Your Skin, Stage by Stage

Hormones affect your skin in three main ways. Some shifts make it oilier and prone to breakouts, and estrogen keeps it thicker and better hydrated. Pregnancy hormones and the pill are thought to trigger dark patches. On darker skin, the dark spots a breakout leaves can last much longer than the breakout itself.

Maybe your skin behaved for years and then changed after a new pill, a pregnancy or a run of strange periods. If so, the cause probably isn't your cleanser. And if the breakout cleared months ago but the dark spot it left is still there, that's a different problem with a different fix.

How Do Hormones Affect Your Skin?

Two effects do most of the work. The first is oil. MedlinePlus lists hormonal changes that make the skin oilier as an acne trigger, tied to puberty, periods, pregnancy, birth control pills and stress. Oil mixes with dead skin cells, plugs a pore, and a pimple follows.

The second is estrogen. In a review of the menstrual cycle and skin, estrogen was associated with increases in skin thickness and dermal water content. When it falls at menopause, skin loses some of that.

A third effect matters more on medium and dark skin. Rising estrogen and progesterone are thought to trigger extra pigment, which is how melasma can start.

Hormones and Skin at Each Life Stage

Each stage pulls a different lever. The table puts them side by side, using only what the sources linked below support, with the detailed article for each.

Stage	What shifts	What skin tends to do	Worth watching	Read next
Menstrual cycle	Progesterone reaches its peak	Acne, eczema, psoriasis and irritant dermatitis can flare around your period	Dark marks from spots on darker skin	Period skin changes
Starting or stopping the pill	Hormone levels fluctuate when you start or stop	Breakouts can start or stop. Some pills are FDA approved to treat acne	Melasma, since the pill is a listed trigger	Hormonal acne treatment
Pregnancy	Estrogen and progesterone rise	The "mask of pregnancy," a dark line on the belly, sometimes acne	Most color changes fade within a few months of birth. Some women keep freckles	Postpartum skin
Perimenopause	Hormones swing up and down	Breakouts can flare	Dark marks from breakouts on darker skin	Perimenopause skin
After menopause	Estrogen drops	Less collagen, drier skin, more acne for some women	Dryness. Cleveland Clinic advises a daily moisturizer and SPF 30+	Skin in your 50s

The pill row cuts both ways. The pill can clear acne or trigger it, and it's also a listed melasma trigger.

Why Does My Skin Break Out Before My Period?

Because some skin conditions flare when progesterone is highest. The cycle review found that acne, psoriasis, eczema and irritant dermatitis can flare around periods, and that flares occur at the peak of progesterone.

Whether progesterone itself is the cause isn't settled. The timing is real, though, and a few months of notes will show you your own pattern. Why your skin changes during your period covers what helps, and why the week-by-week skincare calendars have little behind them.

Can Birth Control Change Your Skin?

Yes, in either direction. The American Academy of Dermatology (AAD) lists starting or stopping birth control pills among the hormone shifts behind adult acne in women. Periods, pregnancy, perimenopause and menopause are on the same list.

It's also a treatment. The AAD says the FDA has approved some oral contraceptives for acne. The AAD notes the pill raises the risk of blood clots, heart attack and high blood pressure, though most healthy women don't have these side effects.

Women with breakouts along the jawline and lower face tend to have good results from hormonal therapy. So a pill that clears one woman's skin can be the reason another woman breaks out after she stops it.

Spironolactone is the other hormonal option. The AAD warns that it can cause serious birth defects, so you need birth control while you take it. If the breakouts keep coming in your 30s and 40s, why adult acne keeps coming back sorts out which kind you have.

What Happens to Your Skin During Pregnancy?

Pigment is the big change. MedlinePlus describes brownish or yellowish patches around the eyes and over the cheeks and nose, known as the mask of pregnancy. A dark line can also appear down the lower belly. Sunlight makes them darker, so a hat and sunscreen matter more now.

The AAD says the rise in estrogen and progesterone in pregnancy is thought to trigger melasma. Melasma is also more common in medium and dark skin tones. Most pregnancy color changes fade within a few months of giving birth, according to MedlinePlus. Some women are left with freckles.

The skincare rules change too. The AAD says to stop isotretinoin, tazarotene and spironolactone right away if you're pregnant, because they can cause serious birth defects. Most experts also advise stopping adapalene and tretinoin.

Azelaic acid is thought to be safe. Benzoyl peroxide is considered safe in limited amounts and salicylic acid for a limited time, but ask your obstetrician or dermatologist before using either.

How Do Perimenopause and Menopause Change Your Skin?

Both can bring breakouts, and dryness follows the estrogen drop after menopause. The AAD lists perimenopause and menopause among the hormone shifts behind adult acne. What happens to your skin in perimenopause goes through the swings in detail.

After menopause, the estrogen drop takes moisture with it. Cleveland Clinic says that when estrogen falls, your skin's collagen production decreases, too, and the skin loses molecules that help it hold water. Some women also get more acne then.

Cleveland Clinic suggests a gentle, non-foaming cleanser, a daily moisturizer (hyaluronic acid helps hold in water) and broad-spectrum SPF 30 or higher every day. It also says there aren't enough controlled studies to show that collagen supplements help skin after menopause. For the slower changes that aren't all hormonal, see skin changes in your 30s and 40s.

Why Do Hormonal Breakouts Leave Dark Marks on Darker Skin?

Because on darker skin, dark spots fade far more slowly than acne clears. The AAD says the dark spots acne leaves on darker skin can last much longer than the acne. A breakout from one bad month can still show long after the spot itself has healed.

That changes the order of the plan. The AAD says treating acne early can stop it getting worse, and that untreated moderate or severe acne raises the risk of darker patches and keloids. Picking adds to the risk of scars.

For acne in skin of color, the AAD says a retinoid with benzoyl peroxide works well, and that retinol can unclog pores and fade dark spots. It suggests starting with 2.5% benzoyl peroxide, Stronger versions can dry and flake, so go slowly.

Pregnancy is where the stages collide. The prescription retinoids are ones to stop or avoid in pregnancy, which is also when hormones are thought to trigger melasma. Azelaic acid is thought to be safe in pregnancy, and daily sun protection helps keep patches from darkening.

How to treat melasma covers the options after birth. Why acne marks last longer on dark skin has the full fading plan.

When Should You See a Doctor About Hormonal Skin?

When the skin is one sign among several. The AAD says acne is sometimes a sign of an underlying condition, and treating that condition often clears it.

Polycystic ovary syndrome (PCOS) is the common one. The Office on Women's Health says it affects 1 in 10 women of childbearing age. Signs include irregular periods, extra hair on the face or chin, and acne on the face, chest and upper back. Skin can also darken along neck creases or under the breasts.

Thyroid problems can change skin too. The NIDDK lists dry skin or dry, thinning hair among the signs of an underactive thyroid, along with tiredness, feeling cold and heavy or irregular periods.

See a doctor if acne arrives with irregular periods or new hair growth, or if dry skin comes with those thyroid signs. The AAD says that if nothing clears your acne, you should see a dermatologist.

If you're pregnant and have persistent itching without a rash, contact your provider promptly rather than waiting for your next appointment. MedlinePlus says it may indicate a more serious condition called cholestasis.

Frequently Asked Questions

Can Hormones Cause Dry Skin?

Yes. Cleveland Clinic says falling estrogen after menopause costs skin some of the molecules that hold moisture. An underactive thyroid can also cause dry skin, so mention it to your doctor if you're tired and cold as well.

Does Birth Control Clear Skin?

Some pills do. The FDA has approved some oral contraceptives for acne, and women with breakouts on the jawline and lower face tend to have good results. Starting or stopping the pill can also trigger breakouts, so a switch can move your skin either way.

Does Pregnancy Melasma Go Away?

Often. MedlinePlus says most pregnancy color changes fade within a few months of birth, though some women keep freckles. Sun makes the patches darker, so daily sunscreen and a hat help keep them from darkening.
