How Caffeine from Coffee Can Reduce Your Rosacea Symptoms

A new study has found that increasing your caffeinated coffee consumption can reduce your risk of rosacea, a chronic inflammatory skin disease characterized by flushing and redness.
“This is certainly a surprising finding. While we believed that hot beverages were rosacea triggers, coffee is not something that’s been on our radar as ‘good’ for rosacea,” Dr. Rajani Katta, a board-certified dermatologist and author of “Glow: The Dermatologist’s Guide to a Whole Foods Younger Skin Diet,” told Healthline.
Coffee has previously been seen as a trigger for rosacea because the heat from the beverage can induce symptom flares.
However, the study authors found the polyphenols in caffeinated coffee could mitigate those effects at doses of four servings per day.
This is why caffeinated coffee, not decaffeinated, not tea, nor chocolate, proves effective.
Caffeinated coffee is further beneficial because it’s a vasoconstrictor, meaning it reduces the rush of blood to the skin’s surface.
It’s also full of protective antioxidants and has an immunosuppressant effect that can help curb inflammation.

Finally, the study authors said that caffeine from coffee can help balance hormone levels that are associated with rosacea, including adrenaline, noradrenaline, and cortisol.
What other experts say
Healthline spoke with dermatologists to see how these findings impact the advice they’ll give their patients with rosacea.
Dr. Patricia Farris, dermatologist and clinical associate professor at the Tulane University School of Medicine in Louisiana, told Healthline: “As a dermatologist, I find this study interesting but not all that helpful… I am not going to tell my patients to drink four cups of coffee a day to control their rosacea. Drinking this much coffee will probably give you the jitters and heart palpitations.”
Katta added that, along with jitters and heart palpitations, there are a number of other health concerns to consider when consuming such servings of caffeinated coffee.
First, she mentioned, is the fact that some people are more sensitive to caffeine than others.
Second, “many people find it hard to drink black coffee. Which means that many people will be adding sugar or cream to their coffee, and all of that extra sugar and cream adds up,” she noted.
