As many of you know, rosacea is a chronic skin condition by which superficial blood vessels cause significant redness to the face. When rosacea worsens in an individual, or when the facial redness becomes more intense, this occurrence is called a rosacea flare.
Additionally, when a particular activity, food item, or medication causes a flare, it is referred to as a trigger. Caffeine is an item that is frequently included in the list of rosacea triggers.
Even though caffeine decreases blood vessel dilatation chemically, it has been theorized that the combination of caffeine and heat as in hot tea or coffee could trigger a flare up of preexisting rosacea. However, just like any preconceptions and even theories, this particular one had been put to the test.
A recent study published in the Journal of the American Medical Association Dermatology (JAMA Dermatology) sought to answer the question of what impact caffeine really has on rosacea. In this study, the researchers used data from the Nurses Health Study 2, which has followed over 82,000 female nurses since 1989.
The study specifically focused on 5,000 women, all of whom had a history of diagnosed rosacea in 2005. The researchers adjusted for a number of risk factors and looked for a correlation between amount of caffeine intake and number of rosacea flares.
The results were very interesting. Not only was caffeine not found to be a trigger for rosacea and its flare-ups, but the researchers found that those who drank more coffee actually had less of a risk of rosacea flares.
Plus, they found no association when caffeine was measured in foods (e.g. chocolate) or other liquids besides coffee (e.g. tea). The researchers also took note of the patients’ intake of decaffeinated drinks, and found no links between them and rosacea flare-ups.
