Research published in JAMA Dermatology found that women who drank four cups of coffee every day were more protected from rosacea. Rosacea is a type of inflammatory disease in the skin that causes redness, lumps, and irritation. In addition, rosacea also often makes blood vessels in the face clearly visible.

Dr. Rajani Katta, a skin disease specialist in the United States states that previously hot drinks were thought to be triggers of rosacea. However, after further research found that coffee, although hot, can actually reduce the risk of symptoms of rosacea.
The study was conducted on 82,737 women to find out the effects of caffeine on coffee on rosacea. These women were interviewed about various health problems they had and how often they drank coffee, tea, soda, and chocolate.
Apparently, the results of the study showed that the more coffee was drunk, the less likely it was to get rosacea. However, this does not apply to tea, soda, and chocolate even though all three contain caffeine.
Why can caffeine in coffee reduce the risk of rosacea?
Research has found that polyphenols in caffeinated coffee are one of the substances that play a role in this. As an antioxidant, polyphenols serve as anti-inflammatories which can help ward off skin inflammation from rosacea.
In addition, caffeine in coffee also acts as a vasoconstrictor that is useful for reducing blood flow to the skin surface. High levels of caffeine in coffee can constrict blood vessels in the face. Not only that, but caffeine in coffee can also help balance the levels of hormones associated with rosacea. Some of these hormones include adrenaline, noradrenaline, and cortisol.
However, further research is still needed to see a clearer relationship between coffee, caffeine, and rosacea, especially for different subtypes.
