Brimonidine vs Oxymetazoline for Redness
Brimonidine (Mirvaso) and oxymetazoline (Rhofade) are topical prescription medications designed to temporarily reduce the background redness seen with rosacea. They work by constricting the small blood vessels in the face. Please note that Rhofade is not widely available in the United Kingdom.
Which works best?
Both can produce a significant, though temporary, reduction in redness for several hours. Some patients find one works better than the other. Brimonidine often has a faster onset and may produce a more dramatic initial effect, but it also carries a higher risk of side effects.
Differences in rebound and tolerance
The main difference is in their side effect profiles. Brimonidine (Mirvaso) has a higher risk of "rebound flushing," where the redness returns even worse than baseline several hours after application as the medicine wears off. It can also sometimes cause a patchy or pale appearance. Oxymetazoline (Rhofade) has a lower risk of rebound flushing, making it a better option for many patients. However, neither is a cure, and both are best used for specific occasions such as presentations or meetings and I do not recommend either of these for long term control of rosacea.
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.
