Editor’s note: It’s important to note that these findings only suggest a potential association. To determine any cause and effect relationship, further study is required.

Researchers in Denmark have reported a potential link between rosacea and migraine headaches, finding an association between the two conditions particularly in women over the age of 50. A relationship between the two conditions has been hypothesized for the past 30 years, but only a handful of studies, mostly with limited sample sizes, have investigated the potential connection.
