Understanding Rosacea

What Should I Look For?

Rosacea can vary substantially from one individual to another, and in most cases some rather than all of the potential signs and symptoms appear. According to a consensus committee and review panel of 28 medical experts worldwide, diagnosis requires at least one diagnostic sign or two major signs of rosacea. Various secondary signs and symptoms may also develop but are not diagnostic.1
