The caffeine in coffee stimulates circulation, which leads to a more radiant, glowing complexion. Just as with your face and body, coffee is a key for eliminating buildup and dead skin
cells. You know how coffee wakes you up in the morning? It does the same thing
for your skin. When applied as a face mask, the stimulating properties
of coffee improve blood flow and making your skin appear radiant,
bright, and, well, alive.
