Probiotics for Rosacea

Given the links between gut health and rosacea, I am often asked whether modulating the gut microbiome with probiotics can help rosacea.

The immune system is immensely complex and it is possible that these could be helpful for some patients, however in my view the evidence is not strong enough to recommend them as a treatment to patients and anecdotally patients that have tried them have not reported good results to me.

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.
