Histamine Intolerance and Rosacea Flares
Histamine is a chemical involved in immune responses. Some patients find that specific foods can trigger a flare of their rosacea and it is possible that histamine contained with these foods can be contributary for a small proportion of patients.
Can histamine be a driver for rosacea flares?
If you notice that your flushing and redness are consistently triggered after consuming high-histamine foods like aged cheese, red wine, processed meats, or fermented products (like sauerkraut), histamine intolerance might be a contributing factor. Other systemic symptoms alongside the flush, such as headaches, hives, or digestive issues, can also be a clue.
Can a low histamine diet help rosacea?
If histamines are triggers for roasacea flares it might seem logical that a low histamine diet could help. However, the diet is very restrictive and difficult to follow long-term. It needs to be followed for a minimum of 1 month to see if there is a benefit and even when patients have relevant symptoms it often does not lead to an improvement in rosacea.
Can antihistamines help rosacea?
While it might seem logical that antihistamines could be helpful, in my experience they rarely have any benefit for rosacea flares. Nevertheless they are safe drugs and it is reasonable to try in patients with relevant symptoms.
How can I help
I see patients in person in central London. An in person consultation allows me to examine the skin directly including features that are difficult to capture in a photograph such as 3-dimensional changes and textural change. This is the better option where the diagnosis is uncertain, where previous treatment has not been effective, or where a procedure is being considered. For more straightforward conditions such as acne and rosacea a remote consultation with clear photographs can be a good option.
