Common Rosacea Triggers and How to Avoid Them

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.

I am a London-based Consultant Dermatologist and Dermatological Surgeon. I am highly experienced in skin cancer diagnosis, Mohs micrographic surgery, acne, rosacea, acne scarring and laser treatments. I studied at the Universities of Cambridge and Oxford, and completed my dermatology training and Mohs fellowship at the prestigious St John's Institute of Dermatology. I graduated from medical school in 2003 and have worked exclusively in Dermatology since 2012.

I lead a research team at King's College London investigating the molecular biology of skin cancer. In recent years I have been involved in Media Appearances, including the Channel 5 series 'Skin A&E', where I perform skin surgeries and treat various skin conditions.

My NHS practice is at Guy's Hospital. I consult with private patients at OneWelbeck (near to Bond Street station) and on Harley Street. Book A Consultation.
