Rosacea is a common skin condition that often begins with a tendency to blush or flush more easily than others, particularly as a result of stress, alcohol consumption, warm temperatures, or eating spicy food. The four sub-types of rosacea include varied symptoms from facial redness, flushing, and visible blood vessels to acne-like breakouts or thickening skin. One sub-type of rosacea affects the eyes and can cause burning, stinging, itching, and blurred vision.
