What is Acne Rosacea?

The earliest written reference to "acne rosacea" appeared in an English medical text by Dr. Thomas Bateman in 1812, who stated that: "The perfect cure of acne rosacea is, in fact, never accomplished." Other 19th century references commonly listed rosacea among the various forms of acne. Dermatologists now know that rosacea is a different skin condition from acne, and that treatment for acne can often make rosacea worse.
