Rosacea triggers are only proposed. There is not one rosacea trigger proposed that produces a rosacea flare up in every rosacea sufferer. Not one. In addition, all rosacea triggers are simply anecdotal, collected in surveys, polls and online posts.
sources for the triggers listed above are listed in the book, Rosacea 101, page 46 and also if you scroll to the bottom of this post in 'Footnotes for the Trigger List' as well as the End Notes. +

Researching Rosacea Trigger Factors
Just think if 10K members of the RRDi each donated one dollar and insisted on supporting a reputable clinician to study what they wanted, supporting their own research, what might be discovered? For example, what about sponsoring investigation into rosacea triggers with an actual double blind, placebo controlled, peer reviewed paper? This can only happen if you want it to happen. Or you can continue to do nothing and let the status quo research continue on.
