Do Hormones Cause Eczema? The Question Answered

Can Hormones Cause Eczema? The Quick Answer

Yes, hormones can cause eczema flares and worsen existing symptoms. Hormones affect your skin's barrier function, inflammation levels, and immune response: all key factors in atopic dermatitis^[31].

Research shows that sex hormones like estrogen and progesterone directly influence how your skin produces protective oils and responds to irritants. When hormone levels fluctuate (during your menstrual cycle, pregnancy, or menopause) your skin becomes more vulnerable to eczema flares^[32].

Understanding How Hormones Affect Your Skin

Your skin isn't just a protective covering. It's an active organ with hormone receptors throughout its layers^[9]. When hormone levels change, these receptors trigger a cascade of effects that can make eczema worse^[10].

The Science Behind Hormones and Inflammation

Your immune system works like a balance scale. In healthy skin, inflammation stays controlled^[11]. But with eczema, that balance already tips toward more inflammation^[12]. Hormones can tip the scale even further^[13].

Think of it this way: your immune system is like a see-saw. Eczema already tips one side up. Certain hormones add more weight to that raised side, making symptoms worse.

Sex hormones specifically affect^[14]:

• Skin barrier function: How well your skin keeps moisture in and irritants out^[15]
• Sebum production: The natural oils that protect your skin^[16]
• Collagen synthesis: Your skin's structural support^[17]
• Inflammatory responses: How strongly your skin reacts to triggers^[18]

Why Some People Are More Sensitive

Not everyone with eczema experiences hormone-related flares. Your sensitivity depends on^[19]:

1. Genetic factors: Some people have more hormone receptors in their skin^[20]
2. Baseline inflammation: Higher inflammation makes you more reactive to hormone changes^[21]
3. Overall hormone balance: Multiple hormone imbalances compound the effects^[22]
4. Stress levels: Stress amplifies hormone sensitivity^[23]

Key Hormones That Trigger Eczema Flares

Different hormones affect your skin in unique ways. Understanding each hormone's role helps you anticipate and manage flares better^[24].

Estrogen: Your Skin's Protector

Estrogen generally helps your skin by^[25]:

• Strengthening the skin barrier^[26]
• Increasing collagen production^[27]
• Improving skin hydration^[28]
• Reducing inflammation^[29]

When estrogen drops (before your period or during menopause), your skin loses this protection. That's why many women notice eczema flares during these times^[30].

Progesterone: The Hidden Culprit

Unlike estrogen, progesterone can worsen eczema by:

• Weakening the skin barrier
• Increasing inflammation
• Making skin more reactive to allergens

Progesterone rises in the second half of your cycle. This explains why 47% of women see their eczema worsen before their period^[1].

"Many of my patients are surprised to learn that the same hormone supporting pregnancy can trigger their worst eczema flares. Understanding this connection transforms how we approach treatment during different cycle phases."

- Dr. Sarah Chen, Dermatologist

Testosterone and Male Pattern Eczema

Men with eczema often have lower testosterone levels than those without the condition. Research shows male atopic dermatitis patients have significantly lower testosterone (447 vs 593 ng/dl)^[7].

Low testosterone may:

• Reduce the skin's natural antimicrobial defenses
• Decrease sebum production, leading to drier skin
• Alter immune responses

Here's what's interesting: low testosterone affects men with eczema, but women with severe eczema have normal testosterone levels^[8].

Cortisol: The Stress Connection

Cortisol, your body's main stress hormone, creates a particularly vicious cycle with eczema:

1. Stress triggers cortisol release
2. Chronic high cortisol weakens your skin barrier
3. Weakened skin leads to more eczema flares
4. Eczema flares cause more stress

Studies prove this connection: the more stressed you feel, the worse your eczema itches^[9]. It's a cycle that feeds on itself.

When Hormones Cause Eczema: Life Stages

Certain life stages bring dramatic hormone changes that can trigger or worsen eczema. Knowing what to expect helps you prepare and adjust your skincare routine accordingly.

Menstrual Cycle Flares

The menstrual cycle creates a hormone roller coaster that affects your skin differently each week:

A large survey confirms what many women already know: 65% experience worse eczema before their period^[10].

Pregnancy Changes

Pregnancy creates the most dramatic hormone shifts, and eczema responds unpredictably:

• 25% improve during pregnancy
• Over 50% experience worsening, especially in the second trimester
• Eczema accounts for 33-50% of all pregnancy skin conditions

^[11]

The immune system shifts toward Th2 dominance during pregnancy to protect the baby, but this same shift can trigger eczema flares^[12].

Menopause Transitions

Menopause brings unique skin challenges:

• Nearly 1/3 of collagen lost in first 5 years after menopause
• 64% of women attending menopause clinics report skin problems
• Declining estrogen means less natural skin protection

^[13]

Many women develop eczema for the first time during menopause, while others see childhood eczema return after decades of clear skin (Nair, 2014)^[14].

Teenage Hormones

Teenagers face unique challenges as puberty hormones surge:

• Androgens increase, potentially improving male eczema but worsening female symptoms
• About 35% of kids outgrow eczema by their teens (previously thought to be 50%)
• Many teens notice eczema patterns changing with their developing cycles

(Wan, 2025)^[15]

Managing Hormone-Related Eczema

While you can't stop hormone fluctuations, you can minimize their impact on your skin. Here's your action plan:

Track Your Patterns

Knowledge is power. Start a symptom diary tracking:

• Menstrual cycle days
• Eczema flare severity (1-10 scale)
• Stress levels
• Sleep quality
• Diet changes

After 2-3 months, patterns emerge. You might discover your eczema always flares on day 20 of your cycle. This knowledge is powerful: you can start preventive eczema cream treatment on day 18.

Adjust Your Skincare Routine

Tailor your routine to your hormone cycle:

Natural Hormone Balance Strategies

Support healthy hormone levels through lifestyle:

1. Regular exercise: 150 minutes/week helps prevent metabolic syndrome and hormone imbalances^[16]
2. Quality sleep: Poor sleep disrupts hormone production. 46.1% of AD patients have excessive daytime sleepiness^[17]
3. Stress management: Try meditation, yoga, or deep breathing to lower cortisol
4. Anti-inflammatory diet: Focus on omega-3s, antioxidants, and phytoestrogens from plants^[18]

Medical Interventions

Sometimes lifestyle changes aren't enough. Discuss these options with your doctor:

Research shows hormone replacement therapy can improve skin elasticity and hydration after 7 months of treatment^[19].

When to See Your Doctor

Hormonal eczema can signal underlying imbalances requiring medical attention. See your doctor if you experience:

Your doctor might recommend:

• Hormone testing: Check thyroid, sex hormones, and cortisol levels
• Allergy testing: Rule out new sensitivities
• Referral to specialists: Dermatologist, endocrinologist, or gynecologist
• Prescription treatments: Stronger medications or hormone therapy

"I struggled with monthly eczema flares for years before my dermatologist suggested tracking my cycle. Once we identified the pattern, we adjusted my treatment to start preventive care three days before my period. It's been life-changing."
