Managing rosacea isn't just about what you put on your skin; it's also about identifying and managing the external and internal factors that cause your symptoms to flare. Keeping a trigger diary can be helpful.

Why do heat, spicy food, alcohol and stress cause flares?

These are common that lead to vasodilation (widening of blood vessels) and inflammation. Heat from saunas, hot showers, or exercise directly dilates facial blood vessels. The capsaicin in spicy foods and the compounds in alcohol, which are common dietary triggers, can stimulate nerve receptors in the skin that cause flushing. Stress triggers the release of cortisol and other hormones that drive an inflammatory response throughout the body, including the skin.

How to manage triggers realistically?

Complete avoidance is often impossible. The goal is recognise and moderate triggers. For example, avoid scalding hot drinks, go for less spicy food, and avoid or moderate alcohol consumption. For stress, incorporate regular relaxation practices like deep breathing, meditation, or gentle exercise.
