We all know what caffeine can do for our moods in the morning, but
caffeine is also increasingly celebrated in the dermatological
community for its impact on the skin.
For
years, caffeine's ability to quickly and effectively constrict blood
vessels has made it a valued topical ingredient, particularly in
products designed to minimize facial flushing. For that reason,
caffeine can be a tremendous boon to those who suffer from rosacea,
which is essentially caused by frequently dilated blood vessels that
lose their ability to contract.
La Roche Posay Rosaliac products, for example, are a great anti-inflammatory option for anyone who suffers from rosacea or facial redness. Topix Replenix CF Anti-Photoaging Complex SPF 45 is another excellent, well-rounded product that offers a blend of powerful antioxidants, caffeine, and sunscreen.
Caffeine's blood vessel-constricting benefits also make it a go-to ingredient in many eye creams (like MD Formulations Moisture Defense Antioxidant Eye Crème, for example), as it can quickly minimize redness and puffiness.
In
addition to its anti-inflammatory benefits, though, caffeine is
starting to get lots of attention for its antioxidant properties when
used both topically and orally. (That morning cup o' joe might not be so bad after all!)
In
fact, research suggests that both oral and topical caffeine may offer
powerful anticarcinogenic benefits. A series of studies performed on
mice found that caffeinated green and black teas prevented sun damage
and even repaired damage once it occurred, whereas decaffeinated teas
did not.
One particularly promising study suggested that
topical caffeine may also repair UV damage - and that it may prove to
be a stronger antioxidant than certain green tea polyphenols, currently
among the strongest and best-researched antioxidants around. (On a
related note, coffeeberry, which comes from the fruit of the coffee plant, is also getting a lot of attention lately as the next big antioxidant.)
Just
a couple words of caution, though: Caffeine is dehydrating, so be sure
to follow your coffee or tea with plenty of water. And if you're prone
to facial flushing, hot beverages can cause redness; consider enjoying
your caffeinated beverages over ice.
