How Your Hormones Affect Rosacea — and What Helps

What is rosacea — and why does it affect women more severely?

Rosacea is a chronic skin condition that primarily appears as persistent redness, visible blood vessels, and periodic flare-ups on the face — especially on the nose, cheeks, and forehead. Many confuse it with sunburn or allergy, but rosacea is an inflammatory condition that does not go away on its own.

What is remarkable is that women are affected three to four times more often than men. This is no coincidence. Women go through a series of hormonal phases throughout life — menstrual cycle, pregnancy, perimenopause, and menopause — and research shows that these phases significantly affect the skin’s ability to manage inflammation. Rosacea and hormones are, in other words, two sides of the same coin for many women.

What estrogen does to the skin — and what happens when it decreases

Estrogen is not just a reproductive hormone. It plays an active role in skin health by regulating immune responses, maintaining the skin barrier’s building blocks, and reducing inflammation. More specifically, estrogen helps maintain ceramides and filaggrin — the lipids and proteins that keep the skin barrier intact. A well-functioning barrier protects the skin from environmental irritants and retains moisture.

When estrogen levels drop — as they do in the days leading up to menstruation, during perimenopause, and in menopause — three things happen simultaneously: the barrier weakens, the skin’s ability to reduce inflammation decreases, and the blood vessels in the face become more reactive. The result is exactly what many women with rosacea know all too well: increased redness, more frequent flushing, and a general feeling that the skin is on "high alert."

A clinical study from 2024 published in PubMed Central examined 59 perimenopausal women with rosacea (average age 48.4 years). The results were clearer than expected: lower estradiol levels correlated statistically significantly with more severe rosacea (p=0.01). Over 71% of participants had moderate to severe rosacea, and nearly half reported anxiety as a consequence.

When in life are rosacea and hormones most connected?

Hormonal fluctuations affect the skin differently depending on where you are in life. Here are the phases most women recognize:

Menstrual cycle: Many women experience worsening rosacea symptoms in the days leading up to menstruation — precisely the phase when estrogen falls and progesterone dominates. Progesterone can increase sebum production and make the skin more reactive. The result is more frequent flushing and possibly pustules resembling acne.

Pregnancy: Hormones are constantly changing during pregnancy. Rising estrogen and progesterone can dilate blood vessels and increase the skin’s warmth and reactivity. Some women experience improvement, others worsening — especially in the second and third trimesters.

Perimenopause and menopause: This is the phase where most women with rosacea notice it most clearly. Estrogen declines irregularly and permanently, and hot flashes — which are themselves a classic rosacea trigger — act like daily flare-ups. In fact, rosacea often first appears in many women during this period precisely because the skin’s natural defense is weakened.

How to build a routine that keeps your skin calm despite hormonal fluctuations

You cannot control your hormones, but you can build a skincare routine that gives your skin the best conditions to cope, even when hormone levels fluctuate. The principle is simple: fewer, gentle products and strong barrier care.

In the morning: Cleanse with a foam cleanser that does not remove the skin’s natural lipid layer. DemSol Mild Foam Cleanser from NIMO SKIN is developed for sensitive and rosacea-prone skin — it cleans effectively without irritating. Then apply a light barrier cream like Grums Hydra Calm Face Cream, which contains hyaluronic acid (attracts moisture and keeps the skin soft), niacinamide (reduces visible redness), and lactic acid (strengthens the barrier without irritating). Finish with factor 50 sunscreen — UV rays are one of the strongest rosacea triggers, and with a weakened skin barrier, the skin is even more vulnerable.

In the evening: Cleanse gently again. Here you can advantageously use ZZ-Creme on the most affected areas. ZZ-Creme contains zinc and sulfur, which work on active inflammation and redness overnight while you sleep. It is a night cream — not a day cream — and works best as the final step in the evening routine.

A complete routine with all three elements can be found in the Rosaceapakken, which combines DemSol Cleanser, ZZ-Creme, and Grums Hydra Calm Cream.

Ingredients that help the skin with rosacea — and those you should avoid

Product choice is crucial when rosacea and hormones create already irritated skin. Here is what research and clinical practice recommend:

Good ingredients: Zinc (anti-inflammatory, reduces redness and regulates bacteria), sulfur (works against superficial inflammations and supports the skin’s natural balance), niacinamide — also called vitamin B3 (strengthens the barrier and reduces redness), ceramides (rebuild the lipids normally maintained by estrogen), hyaluronic acid (hydrates and supports the barrier), and panthenol (soothing and healing effect).

Ingredients to avoid: Alcohol (dries out and irritates), perfume and essential oils (classic triggers for rosacea), strong acids like AHA/BHA in high concentrations (further break down the barrier), menthol and camphor (stimulate blood vessels and increase flushing), as well as very hot water when cleansing.

When should you seek medical help?

Skincare can make a big difference, but it is important to know when professional help is necessary. Contact your doctor or dermatologist if you experience: pustules and bumps resembling acne but not responding to normal treatment, persistent and worsening redness despite gentle care, facial swelling (a rare but serious form of rosacea called rhinophyma in men, or periorbital edema), or eye irritation and sensitive eyes — these may be signs of ocular rosacea, which requires treatment. A dermatologist can prescribe prescription creams such as ivermectin or metronidazole, or in more severe cases, oral treatment.
