Rosacea and Menopause: What's the Connection?

In a study led by Wen-Qing LI, the team observed that the risk of rosacea was significantly reduced in postmenopausal women. The decline in estrogen caused by menopause could explain the decreased risk of rosacea in postmenopausal women. Indeed, estrogens are known to be vasodilators, thus causing telangiectasias , one of the main symptoms of rosacea.

However, in addition to sex hormones, the ovaries also produce asexual hormones, known as prostaglandins. These hormones are the most potent vasomodulators that can trigger a response from the brain's hemodynamic centers, leading to symptoms such as hot flashes and rosacea.Increased production of prostaglandins by the uterus in response to fluctuations in estrogen levels during perimenopause, just before menopause around age 47, could be a risk factor for the development and worsening of rosacea.

Their relationship remains quite controversial, and researchers' opinions on the matter diverge. The variations in sample sizes, along with internal and external factors, are believed to be the cause of these discrepancies.

How to prevent rosacea flare-ups during menopause?

In some instances, rosacea flare-ups may occur during menopause. Here are some general tips to prevent them.

  • Manage your stress. During a stresssituation, the blood vessels dilate, warm blood rushes to the face, and reddens the skin. When these episodes of vasodilation are repeated, there will then be continuous skin inflammation and permanent telangiectasias, characteristics of rosacea. Reduce your stress by practicing stress management techniques such as meditation, yoga, or deep breathing.

  • Protect your skin from the sun. Rosacea predominantly affects individuals with light skin and eyes, who are often prone to photoaging due to UV exposure. UV irradiation promotes photoaging by inducing matrix metalloproteinases (MMPs) that degrade and suppress collagen production, leading to the formation of vascular tubes similar to telangiectasias. Use a sunscreen with broad-spectrum protection and an SPF of 30 or higher every day, even on cloudy days.

  • Avoid rosacea triggers. Various known triggers of rosacea (spicy food, alcohol, sudden temperature changes, etc.) These factors would positively regulate substance P and CGRP, two vasodilators, and cause a significant vasodilation. Therefore, avoid excessive alcohol consumption, spicy food, and situations that could cause a thermal shock.

  • Use non-irritating skincare products. Prioritize the use of gentle products for the skin to avoid irritating and weakening it. Avoid harsh exfoliants, products containing alcohol, perfume.

At the slightest doubt, consult a dermatologist to get personalized advice on managing rosacea during menopause and on the available treatment options if necessary.
